Referring to FIG. 2, being the processing flow schematic diagram of switching equipment upgrade method provided by the invention, the switching equipment liter
Grade method can be applied to the controller in SDN network, the switching equipment upgrade method the following steps are included:
Step 201, the version information capable of updating firmware of switching equipment to be upgraded is determined；
After switching equipment in SDN network is online, OpenFlow can be sent to the controller in SDN network and (opened
Stream) connection request, controller after receiving the OpenFlow connection request, reply OpenFlow back message, with the friendship
Exchange device establishes OpenFlow connection.
Later, NETCONF (Network Configuration Protocol, net that controller can be run according to it
Network configuration protocol), SNMP (Simple Network Management Protocol, Simple Network Management Protocol), or
Information acquiring pattern as defined in OVSDB (Open Virtual Switch Data Base, open virtual switch database),
Obtain the device model and corresponding device version information for establishing the switching equipment of OpenFlow connection, and the equipment that will acquire
Model and corresponding device version information preservation are into local data base.
Controller in the embodiment of the present invention can also preserve newest firmware version information list, can also not protect
It periodically or by administrative staff is taken manually from distal end file as needed automatically in the case where depositing newest firmware version information list
Business device obtains the newest firmware version information list.Including various firmware versions in the newest firmware version information list
The information such as firmware version number, holding equipment type, the newest firmware version information are typically recorded in version APP
In (Application, application program) or general configuration file.
When needing to carry out edition upgrading to the switching equipment in SDN network, controller can be first in local data base
It is middle to search device model corresponding with switching equipment to be upgraded and device version information, then, saved in controller newest
Firmware version list in select switching equipment to be upgraded device model support firmware version information, alternatively, from distal end
The device model support of switching equipment to be upgraded is selected in the newest firmware version information list that file server obtains
Firmware version information will select a firmware version information as friendship to be upgraded later in the firmware version information selected
The version information capable of updating firmware of exchange device.
Under normal conditions, when choosing the version information capable of updating firmware of switching equipment to be upgraded, version levels may be selected
Higher than capable of updating firmware version information of the firmware version information as switching equipment to be upgraded of the device version information.
It wherein, can be by version etc. if the firmware version information that version levels are higher than the device version information is one
Grade is higher than capable of updating firmware version information of the firmware version information of the device version information as switching equipment to be upgraded.So
And if the firmware version that the device model of switching equipment to be upgraded selected from newest firmware version information list is supported
Information be it is multiple, one of them can be chosen from multiple firmware version informations for example and can be the highest firmware version of version levels
Capable of updating firmware version information of this information as switching equipment to be upgraded.
But if the switching equipment to be upgraded is not available version levels highest or higher firmware version information is completed to rise
Grade, the switching equipment to be upgraded then can using the firmware version information once upgraded successfully in the firmware version information selected as
The version information capable of updating firmware of switching equipment to be upgraded.
The content of the newest firmware version information list of above-mentioned acquisition, can also pass through Web UI, Shell or Rest
The modes such as API are for external or user query.
Step 202, it will guide via the message of the switching equipment forwarding to be upgraded to other switching equipment；
When upgrading in the embodiment of the present invention to switching equipment, it can be upgraded for a switching equipment, it can also
To carry out batch upgrade to more switching equipment.For example, can be selected to upgrade specified switching equipment as needed by user
To specified firmware version, it also can choose and batch liter carried out to more specified switching equipment according to specified firmware version
Grade.
Later, update time can also be preset as needed for switching equipment to be upgraded by user, wait reach in advance
When the update time of setting, switching equipment to be upgraded is upgraded.
In addition, controller has the function of the automatic update time of setting when carrying out version management, if user does not set in advance
Update time is set, firmware version can also be carried out to switching equipment to be upgraded according to the automatic update time that the controller is arranged
Upgrading.
Alternatively, if user does not preset update time, it can also be after selecting version information capable of updating firmware, directly
The upgrading of firmware version is carried out according to follow-up process to switching equipment to be upgraded.The present invention is to this without limitation.
Since restarting for switching equipment to be upgraded can be triggered during carrying out firmware version upgrade, to avoid to be upgraded
When switching equipment is restarted, controller is because of message packet loss caused by can not issuing forwarding strategy in time, so when reaching upgrading
Between after (do not presetting update time, when can directly upgrade to switching equipment to be upgraded, then without waiting for reach upgrading
Time), before upgrading to switching equipment to be upgraded, the embodiment of the present invention can also be to original via the switching equipment to be upgraded
The path of forwarding recalculates the new forward-path after excluding the switching equipment to be upgraded, and generates corresponding update stream
List item is issued to all switching equipment on new forward-path, by original via the message of the switching equipment forwarding to be upgraded
It guides to the switching equipment on the new path, and then the message for being sent to switching equipment forwarding to be upgraded is avoided packet loss occur
Situation.
Referring to FIG. 3, it is assumed that VSb121 be switching equipment to be upgraded, receive VMa130 in controller and be sent to VMa131
When the first message of (forwarding via VSb121), controller learns VMa130- according to the destination address and network topology of the message
VMa131 via switching equipment VSb121 to be upgraded path are as follows:
VSa120-VSb121-VSc122-VSf125；
When switching equipment VSb121 to be upgraded is upgraded, then original is guided through the message of VSb121 reachable to other
On the switching equipment of VSf125, it may be assumed that recalculate in the path of VSa120 arrival VSf125 and exclude switching equipment to be upgraded
New forward-path after VSb121, and all switching equipment on new forward-path issue update flow entry, it will be former
It guides via the message of the switching equipment forwarding to be upgraded to the switching equipment on the new forward-path.For example, again
Calculated new path are as follows:
VSa120-VSd123-VSe124-VSf125；
Later, the update flow entry issued respectively to VSa120, VSd123, VSe124, VSf125, by original via
The message of VSb121 forwarding is guided to new forward-path, forwards the message by the switching equipment on new forward-path.
It later, then can be according to update when VSa120 receives the message for being sent to VSb121 during the upgrading of VSb121
Received message is forwarded to VSd123 by flow entry, to avoid forwarding the packet to switching equipment VSb121 to be upgraded, but due to
VSb121 restarts the case where leading to message packet loss.
Meanwhile controller can also all switching equipment on the new forward-path issue according to the new forwarding road
The update flow entry that the reverse path of diameter generates, so that the host of connection VSf125 is when with the main-machine communication for connecting VSa120,
It avoids for message being sent to switching equipment VSb121 to be upgraded.
Further, before controller issues and updates flow entry, in order to avoid being to gather around because of the new path recalculated
Stifled path, the case where still resulting in message packet loss, can also carry out traffic statistics to the new path of calculating, to determine new turn
Whether hair path is to meet the forward-path of preset condition, will be via friendship to be upgraded and when new path meets preset condition
The message of exchange device forwarding is guided according to the destination address of message to the path for meeting preset condition；Determining the new forwarding
Path is the forward-path for being unsatisfactory for preset condition, reach it is preset retry the time when, again to the new forward-path
Carry out traffic statistics.It wherein, include with original in the traffic statistics result by the flow of new forward-path via described to be upgraded
The flow of the forward-path of switching equipment be overlapped after flow；
Judge whether new forward-path is to meet preset condition in the present invention specifically:
If the traffic statistics result is less than or equal to preset bandwidth usage, determine that the new forward-path is full
The forward-path of sufficient preset condition；
If the traffic statistics result is greater than preset bandwidth usage, it is pre- to be unsatisfactory for determine the new forward-path
If the forward-path of condition.
For example, the target MAC (Media Access Control) address of message is VMa-MAC, and the company, host VMa131 institute of target MAC (Media Access Control) address VMa-MAC
The switching equipment connect is VSf125, due to including switching equipment to be upgraded in the original route of VSa120-VSf125, need weight
Newly calculate the new forward-path after excluding switching equipment VSb121 to be upgraded in the path of VSa120-VSf125, it is assumed that root
According to Fig. 4 calculated new path be two equivalent routes:
Path 1:VSa120-VSd123-VSe124-VSf125；And
Path 2:VSa120-VSd123-VSc122-VSf125；
So, the embodiment of the present invention can carry out traffic statistics to above-mentioned two paths respectively, and obtain traffic statistics knot
Fruit.
It should be noted that in order in view of the flow of equipment to be upgraded being guided to new and is turned during subsequent upgrade
The pressure for sending out path, therefore, it is necessary to turn original in new via the flow summation of the forward-path of the switching equipment to be upgraded
Traffic statistics are carried out on hair path.
It is assumed that preset bandwidth usage is 70%, link VSa120-VSd123, VSd123-VSe124, VSe124-
The total bandwidth of VSf125, VSd123-VSc122 and VSc122-VSf125 are respectively 100M, and the bandwidth of VSa120-VSb121 accounts for
Dosage is 20M.
So, the traffic statistics result of path 1 (VSa120-VSd123-VSe124-VSf125) are as follows:
VSa120-VSd123 bandwidth usage are as follows: 40M (VSa120-VSd123 bandwidth usage)+20M (VSa120-
The bandwidth usage of VSb121)=60M；
VSd123-VSe124 bandwidth usage are as follows: 30M (VSd123-VSe124 bandwidth usage)+20M (VSa120-
The bandwidth usage of VSb121)=50M；
VSe124-VSf125 bandwidth usage are as follows: 40M (VSe124-VSf125 bandwidth usage)+20M (VSa120-
The bandwidth usage of VSb121)=60M.
So, it is contemplated that the total occupancy of VSa120-VSd123 bandwidth after flow guidance are as follows: 60%；
It is expected that the total occupancy of VSd123-VSe124 bandwidth after flow guidance: 50%；
It is expected that the total occupancy of VSe124-VSf125 bandwidth after flow guidance: 60%.
The traffic statistics result in path 2 (VSa120-VSd123-VSc122-VSf125) are as follows:
VSa120-VSd123 bandwidth usage are as follows: 40M (VSa120-VSd123 bandwidth usage)+20M (VSa120-
The bandwidth usage of VSb121)=60M；
VSd123-VSc122 bandwidth usage are as follows: 65M (VSd123-VSc122 bandwidth usage)+20M (VSa120-
The bandwidth usage of VSb121)=85M；
VSc122-VSf125 bandwidth usage are as follows: 50M (VSc122-VSf125 bandwidth usage)+20M (VSa120-
The bandwidth usage of VSb121)=70M.
So, it is contemplated that the total occupancy of VSa120-VSd123 bandwidth after flow guidance: 60%；
It is expected that the total occupancy of VSd123-VSc122 bandwidth after flow guidance: 85%；
It is expected that the total occupancy of VSc122-VSf125 bandwidth after flow guidance: 70%.
According to above-mentioned statistical result it is found that path VSa120-VSd123-VSe124-VSf125 is being superimposed VSa120-
After the bandwidth of VSb121, the total occupancy of the bandwidth of each link is not up to preset bandwidth usage 70% therefore can be true
Determining path VSa120-VSd123-VSe124-VSf125 is the path for meeting preset condition；
And due to link VSd123-VSc122 and VSc122- in the VSa120-VSd123-VSc122-VSf125 of path
The total occupancy of the bandwidth of VSf125 has been more than that preset bandwidth usage is 70%, hence, it can be determined that path VSa120-
VSd123-VSc122-VSf125 is not the path for meeting preset condition.
Controller can then guide the message for being sent to VMa131 to the path VSa120-VSd123- for meeting preset condition
VSc122-VSf125, it may be assumed that respectively all switching equipment on the forward-path for meeting preset condition (VSa120, VSd123,
VSc122, VSf125) update flow entry is issued, and then original is guided via the message that VSb121 is forwarded to new forward-path
Switching equipment be forwarded.
Meanwhile controller can also on the new forward-path all switching equipment (VSa120, VSd123,
VSc122, VSf125) it issues according to the reverse path VSf125-VSc122-VSd123-VSa120 of new forward-path generation
Update flow entry so that the host of connection VSf125 when with the main-machine communication for connecting VSa120, avoid for message being sent to
The switching equipment VSb121 of upgrading.
When receiving the message for being sent to VSb121 during the upgrading of VSb121 as a result, controller can be according to current band
Wide busy situation cooks up the more idle new forward-path of bandwidth, and all switching equipment on new forward-path
Update flow entry is issued, so that received message is sent to by VSa120 according to update flow entry by more idle path
VSf125, simultaneously, it is ensured that message not packet loss.
However, if carry out traffic statistics to the new path of calculating, and when determining that preset condition is not satisfied in new path,
Can reach it is preset retry the time when, traffic statistics are carried out to new path again according to the above process, and turn in new
When hair path meets preset condition, all switching equipment on new forward-path issue flow entry to carry out flow guidance.
Wherein, the embodiment of the present invention guides the message forwarded via switching equipment to be upgraded to except switching equipment to be upgraded
The bootstrap technique of other switching equipment in addition updates outside the method for flow entry except through the above-mentioned OpenFlow that issues, can be with
The message forwarded via switching equipment to be upgraded is guided by way of direct traffic in the technologies such as OVSDB or NETCONF
To other switching equipment in addition to switching equipment to be upgraded.For example, can be by new forward-path in NETCONF
All switching equipment issue the control strategies such as ACL (Access Control List, accesses control list) carry out flow draw
It leads, specific process flow can refer to the prior art, and this is no longer going to repeat them.
