Use word " if " can be construed to " and ... time " or " when ... time " or " response
In determining ".
The network equipment logically can be divided into datum plane and control plane, and wherein, datum plane is responsible for number
According to process and forwarding；Control plane to be responsible for controlling and the operation of management procotol, carry for datum plane
The various network informations needed for processing for data and forward and forwarding-table item.
At present, the network equipment commonly used double control planar mechanism, the most primary control plane and standby control
Plane, it is desirable to two procotol state real-time synchronizations controlling plane, so that in the event of primary control plane
Switch to standby control plane during barrier and continue to run with procotol, improve the reliability of the network equipment.
See Fig. 1, for the structural representation of conventional network equipment.Wherein, primary control plane is by logical
Road 1 and data-plane communication, standby control plane passes through passage 2 and data-plane communication, primary control
Communicated by passage 3 between plane and standby control plane.
Procotol status synchronizing process is: after datum plane receives procotol message, above gives master
With control plane (standby control plane not with data-plane communication, passage 2 is in two-way blocked state),
After primary control plane is to procotol Message processing, issue forwarding-table item by passage 1 to datum plane,
Meanwhile, procotol state is sent to standby control plane by passage 3 by primary control plane, to protect
Demonstrate,prove standby control plane and the procotol state consistency of primary control plane.When primary control plane failure
Time, due to standby control plane and the procotol state consistency of primary control plane, therefore, network is assisted
When view is switched to the operation of standby control plane, do not result in network traffic interruption.
But this technical scheme requires that primary control plane frequently communicates with standby control plane, to reach net
Network protocol status real-time synchronization, and also need to back up some control management data, easily cause passage 3
Block up, particularly under some extreme condition, the phenomenon of loss of data can occur because of blocking up.
For the problems referred to above, the embodiment of the present application proposes a kind of procotol state synchronization method, the method
By datum plane, the procotol message of reception given on simultaneously primary control plane and standby control plane,
Standby control plane updates procotol state voluntarily according to procotol message, flat to reach primary control
Face and the procotol state synchronized of standby control plane.
See Fig. 2, for the structural representation of a kind of network equipment shown in the embodiment of the present application.With Fig. 1
The shown network equipment is compared, between primary control plane and the standby control plane in the embodiment of the present application not
Need special communication port again.
Seeing Fig. 3, for an embodiment flow chart of the application procotol state synchronization method, this is real
Execute example procotol status synchronizing process is described.
Step 301, datum plane receiving network protocol message.
Step 302, described procotol message up sending is given primary control plane by datum plane.
In course of normal operation, datum plane only interacts information with primary control plane, when primary control
During plane failure processed, datum plane just from being switched to alternately and standby control plane of primary control plane
Mutual.In the embodiment of the present application, step 301 and step 302 can use prior art to realize, at this
Repeat no more.
Step 303, described procotol message up sending is given standby control plane by datum plane.
Unlike the prior art, the embodiment of the present application is no longer necessary to set up primary control plane and standby
Control the procotol state backup passage between plane, but directly procotol message up sending is given standby
With controlling plane.Detailed process is as follows:
Datum plane obtain be pre-configured with on send strategy, this send strategy for will receive procotol report
Standby control plane is sent on literary composition.Datum plane receive procotol message after with on send strategy to mate,
When procotol message mates and send strategy on this, illustrate that this procotol message is for sending control flat on needing
The message that face processes, now, gives standby control plane by this procotol message up sending.
Step 304, described standby control plane updates procotol shape according to the procotol message received
State, so that described primary control plane is identical with the procotol state of described standby control plane.
From the description of abovementioned steps 301 to step 303 it can be seen that the network that datum plane will receive is assisted
View message gives primary control plane and standby control plane on simultaneously, but it is emphasized that data are put down
Passage between face and standby control plane is two-way obstruction, and datum plane only will match the net sending strategy
Giving standby control plane on network protocol massages, standby control plane cannot send message to datum plane,
It is to say, datum plane only to carry out complete information with primary control plane mutual.
In datum plane with primary control plane information interaction, procotol state is continually changing,
The change of this procotol state can be embodied in mutual procotol message, and therefore, datum plane leads to
Cross the procotol message up sending mutual with primary control plane to standby control plane, make standby control
Plane only can update procotol state voluntarily by the procotol message of change in monitoring network, with
Reach the purpose of procotol state synchronized with primary control plane.
Additionally, for the network partly depending on network-external event (such as, Interface status change etc.)
Protocol status, can be notified the network-external event of perception to primary control plane and standby by datum plane
Control plane, so that primary control plane and standby control plane are assisted according to network-external event update network
View state.
By foregoing description it can be seen that primary control plane and standby control plane are all to update network voluntarily
Protocol status, and the procotol sent in primary control plane and standby control plane due to datum plane
Message is identical, therefore, can accomplish procotol state synchronized, simultaneously, it is to avoid primary in prior art
What control plane was likely to result in when standby control plane backs up blocks up and data loss problem.
The application procotol state synchronized scheme is simple, makes full use of existing procotol and processes
Flow process, does not increase extra hardware and software cost.
Corresponding with the embodiment of aforementioned network protocols state synchronization method, present invention also provides network association
The embodiment of view state synchronizing apparatus.
The embodiment of the application procotol state synchronizing apparatus can be applied on network devices.Device is real
Execute example to be realized by software, it is also possible to realize by the way of hardware or software and hardware combining.With soft
