Further, described after detecting that the first forwarding process is abnormal, the basis is currently
Before one the second forwarding process of configuration backup process creation of operation, can also include: by the configuration backup process to
The control plane, which is sent, prevents message to prevent the control plane from carrying out issuing for configuration message；The institute by creation
It can also include: when the second forwarding process is created before stating the step of the second forwarding process executes the configuration load operation
When building up function, the control plane is notified to put wildcard and set issuing for message.
When detecting that the first forwarding process is abnormal, it can be sent and be prevented to control plane by configuration backup process
Message controls the transmission interprocess communication configuration of planar configuration process at this time and disappears to prevent control plane from carrying out issuing for configuration message
Can be blocked when breath, configuration message will be stored in inter-process communication mechanisms caching in, with etc. process to be forwarded recovery；When
When the second forwarding process creation success, reinforms control plane and put wildcard and set issuing for message, so that network recovery is normal.Pass through
It is this that control plane is prevented to carry out the mode that configuration message issues during Network Abnormal restores, it ensure that during Network Abnormal
The configuration message that control plane generates will not lose, to improve the reliability of Network Abnormal recovery.
The Network Abnormal restoration methods that the present embodiment proposes, since configuration backup process performs and the first forwarding process phase
Same configuration loads operation, therefore it can back up all configurations before the first forwarding process is abnormal, when the first forwarding
When process exception, only subsequent match need to be executed according to the configuration backup process creation being currently running one new forwarding process
Load operation is set, the recovery of Network Abnormal can be realized, compared with the prior art, the present invention is not necessarily to reacquire from configuration plane
Configuration, so as to reduce the recovery time of forwarded service exception, promotes the online experience of user.
Further, it is based on inventive network abnormal restoring method first embodiment, proposes inventive network abnormal restoring
Method second embodiment.
In the present embodiment, described when receiving the configuration message that control plane issues, pass through preset configuration backup
Process and the first forwarding process execute the step of corresponding with configuration message configuration load operation respectively and may include:
The configuration message that control plane issues is received by preset configuration backup process, and judges that the configuration message is
Synchronization message or asynchronous message；When the configuration message is synchronization message, the configuration message is sent to described first
Forwarding process, so that the first forwarding process executes configuration load operation corresponding with the configuration message；Matched by described
It sets backup process and receives the configuration result information that the first forwarding process returns, and the configuration result information is fed back into institute
State control plane；When the configuration result information is configuration successful, controls the configuration backup process and execute and the configuration
The corresponding configuration load operation of message；When the configuration message is asynchronous message, the configuration message is sent to described the
One forwarding process, and control the configuration backup process and the first forwarding process be performed simultaneously it is corresponding with the configuration message
Configuration load operation.
Specifically, normal platform configuration, which issues, generally comprises two kinds of type of messages: 1, synchronization message, and control plane, which is given, to be turned
It sends out plane and sends a configuration message, after needing that Forwarding plane processing is waited to complete and return the result, can just issue next match
Set message；2, asynchronous message, control plane send configuration management message to Forwarding plane, are indifferent to the processing result of message, no
Forwarding plane processing must be waited to complete and return the result.
Based on above two type of message, what Forwarding plane can be issued by configuration backup process reception control plane matches
Message is set, and judges to configure message for synchronization message or asynchronous message.It, first will configuration when configuring message is synchronization message
Message is sent to the first forwarding process, so that the first forwarding process executes configuration load corresponding with configuration message and operates, then,
The configuration result information that the first forwarding process returns is received by configuration backup process, and configuration result information is fed back into control
Plane, when configuration result information is configuration successful, control configuration backup process executes configuration corresponding with the configuration message and adds
Operation is carried, it is thus achieved that configuration backup process is synchronous with the configuration of the first forwarding process under synchronization message type.Work as configuration
When message is asynchronous message, then the configuration message is sent to the first forwarding process, and control configuration backup process and first turn
Hair process is performed simultaneously configuration load operation corresponding with the configuration message, realizes configuration backup under asynchronous message type extremely
Process is synchronous with the configuration of the first forwarding process.
Further, above-mentioned synchronization message includes interface creation message, described when the configuration message is synchronization message,
The configuration message is sent to the first forwarding process, so that the first forwarding process executes and the configuration message pair
The step of configuration load operation answered may include: to create the interface when the configuration message is that interface creates message
Message is sent to the first forwarding process, so that the first forwarding process is right according to interface creation message establishing one
The kernel virtual network device interface answered, and obtain filec descriptor corresponding with the kernel virtual network device interface；
It is described when the configuration result information is configuration successful, control the configuration backup process and execute and the configuration
The step of corresponding configuration load of message operates includes: to control institute when the kernel virtual network device interface creates successfully
It states configuration backup process and obtains the filec descriptor, and the filec descriptor that will acquire from the first forwarding process
It is saved.
Specifically, when configuration backup process receives interface creation message, interface creation message is sent to first
First forwarding process, so that the first forwarding process creates message establishing one corresponding kernel virtual network device according to the interface
Interface, and obtain filec descriptor corresponding with the kernel virtual network device interface, wherein kernel virtual network device interface
The interfaces such as including but not limited to tun/tap；When kernel virtual network device interface creates successfully, control configuration backup process from
First forwarding process obtains filec descriptor, and the filec descriptor that will acquire is saved, in this way, since two processes are same
This corresponding filec descriptor of kernel virtual network device interface of Shi Chiyou, when forwarding process exception to exit, this kernel
Resource will not wither away, and can directly inherit kernel money according to the second forwarding process that configuration backup process is rebuild later
Source eliminates the process of kernel resources reconstruction, further reduces the time of Network Abnormal recovery.
Above-mentioned Network Abnormal recovery process eliminates the operation for reloading configuration reading configuration, and eliminates kernel money
The reconstruction and configuration in source realize second grade quick restoring mechanism below.
