It should be noted that in the case of not conflicting, the embodiment in the present invention and the feature in embodiment can phases
Combination mutually.Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
In embodiments of the present invention, in order to improve the efficiency that neighbours set up, the network equipment is made to provide normal network service,
Embodiments provide a kind of neighbours' method for building up process, be applied to the tunnel module of arbitrary network equipment, such as Fig. 1 institute
Showing, this process may comprise steps of:
S101, when receiving tunnel and deleting message, obtains the destination address in tunnel to be deleted.
In actual applications, the tunnel module of the network equipment can receive tunnel and delete message.Specifically, this tunnel is deleted
Message can be sent by neighbor protocol module.
Such as, when network concussion, when the network equipment disconnects neighborhood with arbitrary neighboring net-work device, neighbor protocol occur
Module will send tunnel to tunnel module and delete message, and notice tunnel module deletes the tunnel that this neighboring net-work device is corresponding.
Or, occur masterslave switchover time, i.e. when the mainboard in the network equipment and backboard generation masterslave switchover, or active and standby enter
When switching between journey, in order to ensure that between neighbor protocol module and the tunnel module of the network equipment, data are protected after masterslave switchover
Holding consistent, thus ensure the accuracy that neighborhood is set up, the neighbor protocol module of the mainboard after switching will be together with tunnel module
Smooth.
Specifically, neighbor protocol module notice tunnel module is smooth when starting, neighbor protocol module can according to oneself
Neighbor information, e.g., mainboard before synchronizes the neighbor information come, or, the neighbor information that self obtains from data base, logical
Know that tunnel module re-creates tunnel.After tunnel module receives establishment tunnel message, can check that this locality has created
This tunnel, if it has been, then put a flag information and return by this tunnel；If do not created, the most newly created tunnel
Road, and put a flag information.It is to say, mark letter all will be included with neighbor protocol module keeps consistent tunnel
Breath rather than according to the tunnel of neighbor protocol module creation, as before tunnel module and particular neighbor protocol module create from
Dynamic tunnel, will not comprise flag information.
After the notification message establishment tunnel juxtaposition flag information that tunnel module sends according to neighbor protocol module completes, can
To send the response message created to neighbor protocol module.After neighbor protocol module receives this response message, Ke Yitong
Know that tunnel module is smooth to terminate.Tunnel module receives smooth end, can travel through the local all of tunnel created, and
Obtain the flag information in each tunnel, determine that the tunnel not comprising flag information is tunnel to be deleted.
Therefore, in embodiments of the present invention, it can be neighbor protocol module that message is deleted in the tunnel that tunnel module receives
The message deleting certain tunnel being sent to.Can also be to receive the flat of neighbor protocol module transmission in smoothing process
Sliding end.
In embodiments of the present invention, after the network equipment receives tunnel deletion message, the mesh in tunnel to be deleted can be obtained
Address.Concrete, the network equipment receives tunnel and deletes message, and the destination address obtaining tunnel to be deleted can have following reality
Existing mode:
Such as, the destination address that can carry tunnel to be deleted in message is deleted in the tunnel that the network equipment receives；Or,
The identification information that can carry tunnel to be deleted in message is deleted in tunnel, each tunnel mark that the network equipment can preserve according to this locality
In the corresponding relation of knowledge information and destination address, search the destination address corresponding with the identification information in tunnel to be deleted, and will look into
The destination address found is defined as the destination address in tunnel to be deleted.
Owing to a tunnel is corresponding to a neighboring net-work device, therefore, the network equipment obtains the purpose in tunnel to be deleted
During address, namely obtain the address of peer network device corresponding to tunnel to be deleted.
Can S102, according to described destination address, it is judged that be connected to peer network device；If it could not, execution step
S103, if it can, perform step S104.
In actual applications, when neighbor protocol module sends tunnel deletion message to tunnel module, may be simply because
Of short duration network concussion.After actually passing a period of time, when tunnel module receives tunnel deletion message, network may be
Recovering normal, the peer network device that tunnel to be deleted is corresponding may can connect.
In this case, if tunnel to be deleted is deleted by tunnel module, successive neighbor protocol module will learn again to treating
Delete the peer network device that tunnel is corresponding and it needs to again set up neighborhood with this peer network device, and re-establish
Tunnel.
In embodiments of the present invention, in order to improve the efficiency that neighbours set up, the network equipment is made to provide normal network service,
After tunnel module receives tunnel deletion message, tunnel to be deleted will not be deleted immediately, but can be according to tunnel to be deleted
Destination address and source address, it is judged that peer network device can be connected to.
If not can connect to peer network device, then show that peer network device may roll off the production line the most, or network event
Barrier does not recovers, and in this case, tunnel module can delete tunnel to be deleted.
If can connect to peer network device, show that neighbor protocol module sends tunnel and deletes message, it may be possible to because
The of short duration concussion of network causes the local terminal network equipment and peer network device to be disconnected neighborhood.In this case, local terminal is shown
The network equipment can set up neighborhood with peer network device, for the neighbours pass quickly set up and between peer network device
System, it is to avoid carry out tunnel deletion, neighbor learning, tunnel set up, with according to neighborhood create corresponding tunnel except that,
In the present embodiment, according to the destination address in tunnel to be deleted, tunnel module can notify that neighbor protocol module is set up and opposite end net
The neighborhood of network equipment, i.e. creates corresponding neighborhood according to tunnel information.
In one implementation, can tunnel module be according to the destination address in tunnel to be deleted and source address, it is judged that
When being connected to peer network device, detection report can be sent according to this destination address and source address to peer network device
Literary composition.After peer network device receives detection messages, response message can be sent to the local terminal network equipment, therefore, when tunnel mould
When block receives the response message that peer network device sends, determine and can connect to peer network device.
Wherein, the detection messages that tunnel module sends can be ICMP (Internet Control Message
Protocol, Internet control message agreement) message.ICMP is a sub-protocol of TCP/IP protocol suite, on IP main frame, road
Message is controlled by transmission between device.Control message refer to network lead to obstructed, main frame whether up to, route whether can use etc. network this
The message of body.
Such as, tunnel module can be sent out to peer network device according to the destination address in tunnel to be deleted and source address
Send detection messages.Then detect whether to receive the response message that peer network device sends, if received, it is determined that can connect
Receive peer network device.
Alternatively, in order to avoid failing to recover in time because of network failure, peer network device does not receives local terminal network and sets
The detection messages that preparation is sent, the local terminal network equipment can repeatedly send message.As, the local terminal network equipment can according to set time
Between be spaced, such as 1 millisecond, 2 milliseconds, 5 milliseconds etc., send detection messages to peer network device, connect improving peer network device
Receive the probability of message.Wherein, in order to can the fastest detecting be connected to peer network device, can arrange shorter
Time interval.On the basis of above-mentioned embodiment, tunnel module can be according to time interval set in advance to opposite end net
Network equipment sends detection messages, and, it is judged that whether the number of times of transmission detection messages reaches the maximum number of times of transmission pre-set.
If not receiving the response message that peer network device sends in being spaced sometime, and reach to set in advance
The maximum number of times of transmission put, it is determined that not can connect to peer network device.
Concrete, tunnel module can preset time interval and detection messages maximum number of times of transmission, when sending one
After individual detection messages, tunnel module can detect whether receive the response that peer network device sends in a time interval
Message, if received, it is determined that can connect to peer network device, does not retransmit detection messages to peer network device.
If do not received, transmission detection messages is to peer network device the most again, and continues whether detection connects in this time interval
Receive the response message that peer network device sends, judge that the maximum whether the detection messages number of times sent reaches to set is sent out simultaneously
Sending number of times, if not receiving the response message that peer network device sends in an arbitrary time interval, and having reached
The maximum number of times of transmission set, it is determined that not can connect to peer network device.
The efficiency of peer network device can be connected to, it is to avoid detection process takies the long time to improve detection,
Whether reach the alternative of the maximum number of times of transmission set as the number of times judging detection messages, optionally, tunnel module can
To preset maximum duration, when receiving response message in this maximum duration, it may be determined that can connect to correspondent network
Equipment；When not receiving response message in maximum duration, tunnel module will not continue to detection, it may be determined that can not connect
To peer network device, peer network device may roll off the production line the most, or network does not also recover.
Wherein, maximum duration set in advance is more than the time interval set.Certainly, at maximum duration model set in advance
In enclosing, tunnel module can only send one-time detection message, it is also possible at set time intervals, repeatedly sends detection report
Literary composition.
In another kind of implementation, can the local terminal network equipment be according to destination address and source address, it is judged that be connected to
During peer network device, it is also possible to according to destination address and source address, the two-way converting inspection between establishment and peer network device
Survey BFD session；As described BFD session UP, determine and can connect to peer network device.
BFD (Bidirectional Forwarding Detection, two-way converting detects) is general a, standard
Quick fault testing mechanism that change, that medium is unrelated and agreement is unrelated, may be used for detecting the Link State in network, it is ensured that energy
Enough it is quickly detected the communication failure between the network equipment, so as to take measures in time, it is ensured that business continuous service.
After the local terminal network equipment creates the BFD session between peer network device, this BFD session can be detected further
Whether it is in UP state.Specifically, the local terminal network equipment can periodically detect whether this BFD session is in UP state.
S103, deletes described tunnel to be deleted.
When the local terminal network equipment determine not can connect to peer network device time, show that peer network device may the most
Rolling off the production line, or network failure does not recovers, in this case, tunnel module can delete tunnel to be deleted.
S104, according to the destination address in described tunnel to be deleted, notice neighbor protocol module is set up and described correspondent network
The neighborhood of equipment.
When the local terminal network equipment determine can connect to peer network device time, show neighbor protocol module send tunnel delete
Message, it may be possible to because network concussion causes the local terminal network equipment and peer network device to be disconnected neighborhood.This situation
Under, show that the local terminal network equipment can set up neighborhood with peer network device, set with correspondent network to quickly set up
