Detailed description of the invention
Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not used to limit
Determine the present invention.
A kind of bandwidth reservation approach that the embodiment of the present invention proposes, is mainly used in bandwidth control in ethernet networks
Device processed realizes reserving service bandwidth, and this bandwidth control apparatus can include for receiving the right of user setup
The end that the input of preset time period and the port bandwidth configuration of reservations parameter corresponding with this preset time period controls
Port band width configuration of reservations unit, for what the parameter of port bandwidth configuration of reservations cell location was verified
Port bandwidth reserve verification unit, for preserve verification successful port bandwidth configuration of reservations unit configured
The port bandwidth configuration of reservations storage unit of parameter, it is used for initiating service creation procedure and by port bandwidth
The RSVP configuration verification that configuration of reservations unit sends over is transmitted to service bandwidth and reserves verification unit
Business configuration unit, for preserve business configuration data business configuration storage unit and for right
The service bandwidth that the resource reservation configuration of port carries out verifying reserves verification unit.
During the reserved realization of service bandwidth, port bandwidth configuration of reservations unit receive user's input
Preset time period and the configuration information of the port bandwidth configuration of reservations parameter corresponding with this preset time period,
And be sent to port bandwidth and reserve verification unit and verify.Reserve verification unit when port bandwidth to verify into
After merit, configuration information is sent to business configuration unit；Otherwise, if port bandwidth reserves verification unit school
Test failure, then return the information that the configuration information verification of port is failed.Business configuration unit will receive
Configuration information is transmitted to service bandwidth and reserves verification unit and verify, if service bandwidth reserves verification unit
Verify successfully, then configuration information is sent to business configuration unit, and given end by business configuration unit forwards
Port band width configuration of reservations unit, then port bandwidth configuration of reservations unit issues port bandwidth configuration of reservations guarantor
Memory cell stores；Verify unsuccessfully if service bandwidth reserves verification unit, then return the configuration letter of business
The information that breath verification is failed.
When user requires that certain business has guaranteed bandwidth within certain specific time period, and at another
When there is no guarantee that bandwidth requirement in the time period, not only to provide bandwidth parameter when business configuration, in addition it is also necessary to
On the port that business is corresponding, configured bandwidth is reserved.Such that it is able to ensure access service by RSVP
Port can carry the business of the guarantee bandwidth in limited scope, the most effectively keep away creating Service Period
Exempt from resource contention, provide reliable Bandwidth guaranteed for business.
As shown in Figure 1, it is shown that one RSVP method for parameter configuration one embodiment of the present invention.This reality
The RSVP method for parameter configuration executing example comprises the following steps:
Step S10, receive the RSVP parameter of user configured port；Described RSVP parameter includes
RSVP and preset time period；
In the present embodiment, user can be pre-by the bandwidth of the port of port bandwidth configuration of reservations cell location
Staying parameter, this RSVP parameter includes preset time period and the RSVP corresponding with this preset time period,
This port can be physical port or logic port.This preset time period can be to be divided into multiple by the time of one day
Time period, it is possible to arrange as the case may be and flexibly.RSVP comprises the steps that static guarantee reserves band
The reserved bandwidth of guarantee wide, dynamic, peak value reserve bandwidth and port convergence ratio etc..Wherein, it is ensured that reserved band
Width includes that static guarantee is reserved bandwidth and dynamically ensure reserved bandwidth, and static state ensures that reserved bandwidth refers in industry
When business creates, specified services flows through to another port from a port, dynamically ensures that reserved bandwidth refers to industry
Business flows through to another port from a certain port according to protocol generation business when creating, and peak value is reserved bandwidth and referred to
The maximum bandwidth that business flows through.
Below it is illustrated, as a example by the physical port of an Ethernet, it is assumed that its physical port
Available bandwidth (i.e. port speed) is 1000M, and can arrange the first preset time period is 00:00 to 11:
59, and the RSVP parameter of configuration includes within this time period: the reserved bandwidth of static guarantee may be configured as
100M, dynamically ensures that reserved bandwidth may be configured as 80M, and peak value is reserved bandwidth and be may be configured as 200M, end
Mouth convergence ratio may be configured as 80%；Arranging the second preset time period is 12:00 to 23:59, and when this
Between in section the RSVP parameter of configuration include: static ensure that reserved bandwidth may be configured as 200M, dynamically protect
The reserved bandwidth of card may be configured as 100M, and peak value is reserved bandwidth and be may be configured as 300M, and port convergence ratio can set
It is set to 80%.Now, within the time period that the two is different, it is provided that two kinds of different RSVPs are joined
Putting, wherein, the RSVP in the second preset time period requires the RSVP than the first preset time period
Many.
Step S20, determine in preset time period each described whether described RSVP meets and preset bar
Part；
After above-mentioned user is by the RSVP parameter of the port of port bandwidth configuration of reservations cell location,
In order to ensure that the distribution of RSVP does not the most produce conflict in each preset time period, needs time default
Between section and the RSVP corresponding with this preset time period carry out the first verification；And in order to ensure that business exists
During use, current business does not produces with the distribution of RSVP in each preset time period
Conflict, needs preset time period and the RSVP corresponding with this preset time period are carried out the second verification,
Pre-conditioned to judge whether to meet.Wherein, this pre-conditioned include the first verification condition and second verification
Condition.
First pass through and port bandwidth is reserved verification unit carry out the first verification, if the first verification is unsuccessful,
Then point out RSVP verification the configuration failure information, i.e. RSVP in each preset time period of port
It is unsatisfactory for the first verification condition；If first verifies successfully, then reserve verification unit by service bandwidth and carry out
Second verification.When the second verification is unsuccessful, then the RSVP verification configuration failure of prompt service, i.e. exists
In each preset time period, RSVP is unsatisfactory for the second verification condition；When second verifies successfully, it is determined that
In each preset time period, RSVP meets pre-conditioned.
Step S30, when described RSVP meets pre-conditioned, by described each preset time period with right
The RSVP answered is associated storage；
After above-mentioned second time verifies successfully, illustrate that the reserved band width configuration of port does not has with current business
Conflict, i.e. RSVP meets pre-conditioned, then the most every by port bandwidth configuration of reservations storage unit
Individual preset time period is associated storage with corresponding RSVP；Otherwise, if second time verifies unsuccessfully,
Then the configuration of this RSVP is not preserved.
Further, if described RSVP parameter does not include preset time period, then by described RSVP
Reserve as real-time bandwidth.If it should be noted that by the end of port bandwidth configuration of reservations cell location
Mouthful RSVP parameter time, be configured without preset time period, then this RSVP give tacit consent at All Time
In, will reserve as real-time bandwidth by RSVP.
The embodiment of the present invention by user to port configuration preset time period and corresponding with this preset time period
RSVP, and in each preset time period, the first verification condition and the second verification ought be met by RSVP
When condition etc. are pre-conditioned, each preset time period is associated with corresponding RSVP storage.Make
Obtain user and can carry out RSVP configuration for the different time periods, meet user and require certain business
Within certain time period, have guaranteed bandwidth, improve the utilization rate in broadband.
Further, as in figure 2 it is shown, based on above-described embodiment, in the present embodiment, above-mentioned steps S20
Comprise the steps that
Step S21, judging in preset time period each described, described port all of static ensures pre-
Bandwidth and all of dynamic guarantee is stayed to reserve whether bandwidth sum is less than or equal to the available band of described port
Width, and whether the peak value of described port reserve bandwidth and ensure more than or equal to all of static of described port
Reserved bandwidth reserves bandwidth sum with all of dynamic guarantee；
Above-mentioned user after each preset time period configured bandwidth is reserved, in order to ensure in each time period
The distribution of interior RSVP does not the most produce conflict, needs to reserve verification unit to wide port by port bandwidth
Band reserve parameter and carry out verifying for the first time, i.e. to all of preset time period, and with this Preset Time
The RSVP of section correspondence carries out unifying verification, it is desirable in each time period, the distribution of RSVP is not produced
Raw conflict.First verification condition of port check bit RSVP can be: in each preset time period, right
In all of the port: all of static ensure that reserved bandwidth+all of dynamic guarantee reserves bandwidth≤port can
Use bandwidth；Meanwhile, the peak value of port reserves bandwidth >=port all of static ensure reserved bandwidth+all
Dynamically ensure reserved bandwidth.If meeting the first verification condition, then first verifying successfully, port bandwidth is pre-
Stay verification unit that the RSVP parameter of port is sent to business configuration unit.Otherwise, if being unsatisfactory for,
Then explanation first verifies unsuccessfully, returns the RSVP verification configuration failure information of port, and user can root
Again RSVP parameter is carried out reasonable disposition according to this information.
Therefore, according to above-mentioned set parameter, in time period 00:00 to 11:59, port quiet
State ensures that reserved bandwidth 100M+ dynamically ensures reserved bandwidth 80M=180M, less than the available bandwidth of port
1000M.Meanwhile, the peak value of port is reserved bandwidth 200M and is reserved bandwidth and dynamically guarantee more than static guarantee
Reserved bandwidth sum 180M.Therefore, the parameter configured within this time period meets the first verification condition.
In time period 12:00 to 23:59, the static of port ensures that reserved bandwidth 200M+ dynamically ensures pre-
Stay bandwidth 100M=300M, less than the available bandwidth 1000M of port.Meanwhile, the reserved band of the peak value of port
Wide 300M ensures reserved bandwidth equal to static state and dynamically ensures reserved bandwidth sum 300M.Therefore, at this
The parameter configured in time period also meets the first verification condition, to sum up illustrates that this RSVP parameter meets
First verification condition.
If all of static of the described port of step S22 ensures that reserved bandwidth is reserved with all of dynamic guarantee
Bandwidth sum is less than or equal to the available bandwidth of described port, and the peak value of described port is reserved band and is wider than
Or equal to described port all of static ensure reserved bandwidth and all of dynamic guarantee reserve bandwidth it
With, then judge in preset time period each described, through the guarantee bandwidth of all business of described port
Whether sum ensures reserved band less than or equal to all of static of described port with the product of port convergence ratio
Bandwidth sum is reserved in wide and all of dynamic guarantee；
When above-mentioned first of RSVP in each time period is verified successfully after, in order to ensure that business exists
During use, current business does not produce with the distribution of RSVP within each time period conflicts,
In service creation procedure, business configuration unit needs for traffic assignments bandwidth, and pre-by service bandwidth
Stay verification unit that the RSVP parameter of the port that business configuration unit forwards comes is carried out the second verification.
It addition, above-mentioned first of RSVP parameter in each time period is verified successfully after, i.e. in institute
State port all of static ensure reserved bandwidth and all of dynamic guarantee reserve bandwidth sum less than or etc.
In the available bandwidth of described port, the peak value of described port reserves the bandwidth institute more than or equal to described port
Some reserved bandwidth of static guarantee reserve bandwidth sum with all of dynamic guarantee, and are carrying out service creation
Time, in service creation procedure, the peak value of described port is reserved the peak value that band width configuration is business and reserves
Bandwidth.Now, it is not necessary to peak value is reserved bandwidth and is further verified, thus facilitate business
Peak value reserves the use of bandwidth.
It should be noted that a bandwidth can exist multiple business, each business can be in multiple differences
Time period configuration there is different or identical service bandwidth reserve parameter.This business refers to have end-to-end
The tunnel of linking relationship, pseudo-wire and the various teleservices of their carryings.
In particular it is required that the RSVP to the preset time period demand of the bandwidth of business and bandwidth with port
And preset time period compares, it is desirable to the RSVP of all business through port configures and presets
Time period meets the RSVP of port and the configuration of preset time period thereof.This verification business uses process band
Second verification condition of bandwidth reservation may be configured as: in each preset time period, through this configuration port
The reserved bandwidth of all static guarantee of the guarantee bandwidth sum * port convergence ratio≤port of all business+all
Dynamically ensure reserved bandwidth.If before the RSVP parameter of configuration port, port is configured
Business, at this moment needs directly the parameter of configuration to be issued service bandwidth and reserves verification unit and verify.
Below it is illustrated, it is assumed that in time period 00:00 to 11:59, port is configured
Three business, these three business to ensure that bandwidth is the bandwidth of configuration in 100M, and this time period pre-
Stay parameter consistent with the above.Then within this time period, the guarantee bandwidth sum of three business is
3*100M=300M, now, guarantee bandwidth 300M* port convergence ratio 80%=240M of business is more than
The static of port ensures reserved bandwidth 100M and dynamically ensures reserved bandwidth 80M sum.Now,
A time period is had to be unsatisfactory for condition, it is not necessary to time period 12:00 to 23:59 to be verified again,
Therefore, the reserved band width configuration of port has with current business conflicts, this situation configuration failure,
I.e. second time verifies unsuccessfully, needs to return to user-dependent configuration failure information, i.e. returns the band of business
Bandwidth reservation configuration failure information.If in time period 00:00 to 11:59, this port is only configured with one
Individual business, a width of 100M of guarantee band of business, then within this time period, guarantee bandwidth 100M* of business
Port convergence ratio 80%=80M ensures reserved bandwidth 100M less than the static of port and dynamically ensure reserved
Bandwidth 80M sum.In time period 12:00 to 23:59, the guarantee bandwidth 100M* port of business
Convergence ratio 80%=80M ensures reserved bandwidth 200M less than the static of port and dynamically ensure reserved bandwidth
100M sum.Now, the reserved band width configuration of port is not conflicted with current business, this feelings
Condition configuration successful, i.e. second time verify successfully.
If step S23 is through the guarantee bandwidth sum of all business of described port and taking advantage of of port convergence ratio
The long-pending reserved bandwidth of all of static guarantee band reserved with all of dynamic guarantee less than or equal to described port
Wide sum, then in each described preset time period, described RSVP meets pre-conditioned.
The present embodiment carries out the first verification and second when above-mentioned to the RSVP in each preset time period
Verification is all successful, then in each preset time period is described, RSVP meets pre-conditioned.
Further, based on above-described embodiment, in the present embodiment, above-mentioned steps S30 comprises the steps that
Added Business in the current business of described port, it is judged that in preset time period each described, warp
Whether the guarantee bandwidth sum of all business crossing described port is less than or equal to the product of port convergence ratio
The all of static of described port ensures that reserved bandwidth reserves bandwidth sum with all of dynamic guarantee；
If it is not, the RSVP configuration failure information of then prompt service.
Specifically, enter meeting pre-conditioned each preset time period with corresponding RSVP above-mentioned
Row association storage after, through port business to this RSVP parameter use during, when end
In the current business of mouth during Added Business, need to carry out above-mentioned second time verification.When the institute through port
The guarantee bandwidth sum of business is had to reserve more than all of static guarantee of port with the product of port convergence ratio
When bandwidth sum is reserved in bandwidth and all of dynamic guarantee, the reserved band width configuration of port and business now
There are conflict, second time to verify unsuccessful, return the RSVP configuration failure information of business.
Assuming in time period 00:00 to 11:59, the current business of port is 2, these 2 industry
That is engaged in ensures that the RSVP parameter that bandwidth configures in being 100M, and this time period is consistent with the above.Then
Within this time period, the guarantee bandwidth sum of 2 business is 2*100M=200M, now, and the guarantor of business
Card bandwidth 200M* port convergence ratio 80%=160M less than port static ensure reserved bandwidth 100M with
Dynamically ensure reserved bandwidth 80M sum.But, if now creating a guarantor on the basis of current business
The card business with a width of 100M, then guarantee bandwidth 300M* port convergence ratio 80%=240M of business is little
Static in port ensures reserved bandwidth 100M and dynamically ensures reserved bandwidth 80M sum.Now,
Through there being a time period to be unsatisfactory for condition, it is not necessary to again time period 12:00 to 23:59 is verified
?.Therefore, the reserved band width configuration of port has with current business conflicts, and the configuration of this situation is lost
Lose, i.e. second time verifies unsuccessfully, returns the RSVP configuration failure information of business.
Similarly, it is assumed that in time period 00:00 to 11:59, the current business of port is 1,
The RSVP parameter and above-mentioned one of configuration in the equal 100M of guarantee bandwidth of this 1 business, and this time period
Cause.But, within this time period, ensure to carry a width of 100M if creating one on the basis of current business
Business, then guarantee bandwidth 200M* port convergence ratio 80%=160M of business is less than the static state of port
Ensure reserved bandwidth 100M and dynamically ensure reserved bandwidth 80M sum.And at time period 12:00 extremely
Also the demand of bandwidth is ensured after meeting Added Business in 23:59.Therefore, the reserved band width configuration of port with
Current business is not conflicted, and the RSVP parameter of the above-mentioned configuration of this situation is effective.
Accordingly, as it is shown on figure 3, propose one RSVP parameter configuration device first of the present invention and implement
Example.The RSVP parameter configuration device of this embodiment includes:
Receiver module 100, for receiving the RSVP parameter of user configured port；Described RSVP
Parameter includes RSVP and preset time period；
In the present embodiment, user can be pre-by the bandwidth of the port of port bandwidth configuration of reservations cell location
Staying parameter, so that receiver module 100 receives this RSVP parameter, this RSVP parameter includes presetting
Time period and the RSVP corresponding with this preset time period, this port can be physical port or logic port.
This preset time period can be that the time of one day is divided into multiple time period, it is possible to flexible as the case may be
Arrange.RSVP comprises the steps that static guarantee is reserved bandwidth, dynamically ensures that reserved bandwidth, peak value are reserved
Bandwidth and port convergence ratio etc..Wherein, it is ensured that reserved bandwidth includes that static guarantee is reserved bandwidth and dynamically protect
The reserved bandwidth of card, the reserved bandwidth of static guarantee refers to that specified services flows through from a port when service creation
To another port, dynamically ensure when reserved bandwidth refers to service creation according to protocol generation business from a certain
Port flows through to another port, and peak value reserves the maximum bandwidth that bandwidth refers to that business flows through.
Below it is illustrated, as a example by the physical port of an Ethernet, it is assumed that its physical port
Available bandwidth (i.e. port speed) is 1000M, and can arrange the first preset time period is 00:00 to 11:
59, and the RSVP parameter of configuration includes within this time period: the reserved bandwidth of static guarantee may be configured as
100M, dynamically ensures that reserved bandwidth may be configured as 80M, and peak value is reserved bandwidth and be may be configured as 200M, end
Mouth convergence ratio may be configured as 80%；Arranging the second preset time period is 12:00 to 23:59, and when this
Between in section the RSVP parameter of configuration include: static ensure that reserved bandwidth may be configured as 200M, dynamically protect
The reserved bandwidth of card may be configured as 100M, and peak value is reserved bandwidth and be may be configured as 300M, and port convergence ratio can set
It is set to 80%.Now, within the time period that the two is different, it is provided that two kinds of different RSVPs are joined
Putting, wherein, the RSVP in the second preset time period requires the RSVP than the first preset time period
Many.

Within certain time period, have guaranteed bandwidth, improve the utilization rate in broadband.
Further, as shown in Figure 4, based on above-described embodiment, above-mentioned in this embodiment module 200 is determined
Comprise the steps that
First judging unit 210, for judging in preset time period each described, owning of described port
Static ensure that whether reserved bandwidth and all of dynamic guarantee reserve bandwidth sum less than or equal to described end
Mouthful available bandwidth, and the peak value of described port reserves bandwidth whether all more than or equal to described port
Static ensure that reserved bandwidth reserves bandwidth sum with all of dynamic guarantee；
Above-mentioned user after each preset time period configured bandwidth is reserved, in order to ensure in each time period
The distribution of interior RSVP does not the most produce conflict, and the first judging unit 210 needs to be reserved by port bandwidth
The band of wide port is reserved parameter and is carried out verifying for the first time by verification unit, i.e. to all of preset time period,
And the RSVP corresponding with this preset time period carries out unifying verification, it is desirable to bandwidth in each time period
Reserved distribution does not the most produce conflict.First verification condition of port check bit RSVP can be: at each
In preset time period, for all of the port: all of reserved bandwidth+all of dynamic guarantee of static guarantee is pre-
Stay the available bandwidth of bandwidth≤port；Meanwhile, the peak value of port reserves bandwidth > all of static state of=port
Ensure that bandwidth is reserved in reserved bandwidth+all of dynamic guarantee.If meeting the first verification condition, then the first verification
Success, port bandwidth is reserved verification unit and the RSVP parameter of port is sent to business configuration unit.
Otherwise, if being unsatisfactory for, then explanation first verifies unsuccessfully, returns the RSVP verification configuration failure of port
Information, user can carry out reasonable disposition to RSVP parameter again according to this information.
Therefore, according to above-mentioned set parameter, in time period 00:00 to 11:59, port quiet
State ensures that reserved bandwidth 100M+ dynamically ensures reserved bandwidth 80M=180M, less than the available bandwidth of port
1000M.Meanwhile, the peak value of port is reserved bandwidth 200M and is reserved bandwidth and dynamically guarantee more than static guarantee
Reserved bandwidth sum 180M.Therefore, the parameter configured within this time period meets the first verification condition.
In time period 12:00 to 23:59, the static of port ensures that reserved bandwidth 200M+ dynamically ensures pre-
Stay bandwidth 100M=300M, less than the available bandwidth 1000M of port.Meanwhile, the reserved band of the peak value of port
Wide 300M ensures reserved bandwidth equal to static state and dynamically ensures reserved bandwidth sum 300M.Therefore, at this
The parameter configured in time period also meets the first verification condition, to sum up illustrates that this RSVP parameter meets
First verification condition.
For all of static of described port, second judging unit 220, if ensureing that reserved bandwidth is with all of
Dynamically ensure the reserved bandwidth sum available bandwidth less than or equal to described port, and the peak value of described port
Reserved bandwidth ensures reserved bandwidth and all of dynamic guarantee more than or equal to all of static of described port
Reserved bandwidth sum, then judge in preset time period each described, through all business of described port
The product of guarantee bandwidth sum and port convergence ratio whether less than or equal to all of static state of described port
Ensure that reserved bandwidth reserves bandwidth sum with all of dynamic guarantee；
When above-mentioned first of RSVP in each time period is verified successfully after, in order to ensure that business exists
During use, current business does not produce with the distribution of RSVP within each time period conflicts,
In service creation procedure, business configuration unit needs for traffic assignments bandwidth, and by the second judging unit
220 reserve the verification unit RSVP to the port that business configuration unit forwards comes by service bandwidth
Parameter carries out the second verification.
It addition, above-mentioned first of RSVP parameter in each time period is verified successfully after, configuration is single
At all of static of described port, unit, for ensureing that reserved bandwidth reserves bandwidth with all of dynamic guarantee
Sum is less than or equal to the available bandwidth of described port, and the peak value of described port is reserved bandwidth and is more than or equal to
Described port all of static ensures that bandwidth sum is reserved in reserved bandwidth and all of dynamic guarantee, and
When carrying out service creation, in service creation procedure, it is industry that the peak value of described port is reserved band width configuration
The peak value of business reserves bandwidth.Now, it is not necessary to peak value is reserved bandwidth and is further verified, thus
The peak value facilitating business reserves the use of bandwidth.
It should be noted that a bandwidth can exist multiple business, each business can be in multiple differences
Time period configuration there is different or identical service bandwidth reserve parameter.This business refers to have end-to-end
The tunnel of linking relationship, pseudo-wire and the various teleservices of their carryings.
Specifically, the second judging unit 220 needs the preset time period demand of the bandwidth to business and bandwidth
Compare with RSVP and the preset time period of port, it is desirable to the bandwidth of all business through port
Configuration of reservations and preset time period thereof meet the RSVP of port and the configuration of preset time period thereof.This school
Business of testing uses the second verification condition of process RSVP may be configured as: in each preset time period,
Pass through all static state of the guarantee bandwidth sum * port convergence ratio≤port of all business of this configuration port
Ensure that bandwidth is reserved in reserved bandwidth+all of dynamic guarantee.If configuration port RSVP parameter it

Verification certificate unit verifies.
Below it is illustrated, it is assumed that in time period 00:00 to 11:59, port is configured
Three business, these three business to ensure that bandwidth is the bandwidth of configuration in 100M, and this time period pre-
Stay parameter consistent with the above.Then within this time period, the guarantee bandwidth sum of three business is
3*100M=300M, now, guarantee bandwidth 300M* port convergence ratio 80%=240M of business is more than
The static of port ensures reserved bandwidth 100M and dynamically ensures reserved bandwidth 80M sum.Now,
A time period is had to be unsatisfactory for condition, it is not necessary to time period 12:00 to 23:59 to be verified again,
Therefore, the reserved band width configuration of port has with current business conflicts, this situation configuration failure,
I.e. second time verifies unsuccessfully, needs to return to user-dependent configuration failure information, i.e. returns the band of business
Bandwidth reservation configuration failure information.If in time period 00:00 to 11:59, this port is only configured with one
Individual business, a width of 100M of guarantee band of business, then within this time period, guarantee bandwidth 100M* of business
Port convergence ratio 80%=80M ensures reserved bandwidth 100M less than the static of port and dynamically ensure reserved
Bandwidth 80M sum.In time period 12:00 to 23:59, the guarantee bandwidth 100M* port of business
Convergence ratio 80%=80M ensures reserved bandwidth 200M less than the static of port and dynamically ensure reserved bandwidth
100M sum.Now, the reserved band width configuration of port is not conflicted with current business, this feelings

RSVP be associated storage after, through the business of port in the mistake that this RSVP parameter is used
Cheng Zhong, when Added Business in the current business of port, needs to carry out above-mentioned second time verification.When
Guarantee bandwidth sum through all business of port is more than all of of port with the product of port convergence ratio
When the reserved bandwidth of static guarantee reserves bandwidth sum with all of dynamic guarantee, the reserved band width configuration of port
Having with business now and conflict, second time verifies unsuccessful, returns the RSVP configuration failure letter of business
Breath.
Assuming in time period 00:00 to 11:59, the current business of port is 2, these 2 industry
That is engaged in ensures that the RSVP parameter that bandwidth configures in being 100M, and this time period is consistent with the above.Then
Within this time period, the guarantee bandwidth sum of 2 business is 2*100M=200M, now, and the guarantor of business
Card bandwidth 200M* port convergence ratio 80%=160M less than port static ensure reserved bandwidth 100M with
Dynamically ensure reserved bandwidth 80M sum.But, if now creating a guarantor on the basis of current business
The card business with a width of 100M, then guarantee bandwidth 300M* port convergence ratio 80%=240M of business is little
Static in port ensures reserved bandwidth 100M and dynamically ensures reserved bandwidth 80M sum.Now,
Through there being a time period to be unsatisfactory for condition, it is not necessary to again time period 12:00 to 23:59 is verified
?.Therefore, the reserved band width configuration of port has with current business conflicts, and the configuration of this situation is lost
Lose, i.e. second time verifies unsuccessfully, returns the RSVP configuration failure information of business.
Similarly, it is assumed that in time period 00:00 to 11:59, the current business of port is 1,
The RSVP parameter and above-mentioned one of configuration in the equal 100M of guarantee bandwidth of this 1 business, and this time period
Cause.But, within this time period, ensure to carry a width of 100M if creating one on the basis of current business
Business, then guarantee bandwidth 200M* port convergence ratio 80%=160M of business is less than the static state of port
Ensure reserved bandwidth 100M and dynamically ensure reserved bandwidth 80M sum.And at time period 12:00 extremely
Also the demand of bandwidth is ensured after meeting Added Business in 23:59.Therefore, the reserved band width configuration of port with
Current business is not conflicted, and the RSVP parameter of the above-mentioned configuration of this situation is effective.
