Description
Technical field
The present invention relates to the data communication technology field, relate in particular to a kind of system hot standby processing method, management board and communication apparatus.
Background technology
In the data communication field, major product comprises router and switch, owing to have the lot of data message in the backbone network, then all there are the possibility of inefficacy in router or switch.Wherein, core router or switch often dispose redundant hardware and software resource, can switch on the corresponding resource backup after active router or switch inefficacy.Yet present most product need restart the route control process on the resource backup, as Border Gateway Protocol (Border GatewayProtocol after switching; Hereinafter to be referred as: BGP), SPF (Open Short Path First; Hereinafter to be referred as: OSPF), the multicast routing protocol of protocol-independent etc., connect with neighbours again and carry out route and calculate, this will cause the lot of data message to be dropped in handoff procedure, network topology changes and phenomenon such as route oscillation occurs.Therefore, uninterrupted route (Non-Stop Routing; Hereinafter to be referred as: NSR) and uninterrupted forwarding (Non-Stop Forwarding; Hereinafter to be referred as: NSF) technology is arisen at the historic moment, in network behind router or the switch single point failure, make resource backup to take over seamlessly, maintenance is connected and route switching with the peripheral adjacent router, and in handoff procedure, keep data forwarding, so that single point failure is reduced to minimum degree to the negative effect of network.
In the prior art, the scheme that realizes the NSR/NSF technology comprise that agreement is restarted slowly, Hardware Mirroring, system information Hot Spare and agreement mirror image etc.Agreement is therein restarted in the scheme slowly, and after the route control process of active router lost efficacy, active router still can be transmitted data message, and restarts route control process in the near future in inefficacy.Neighbor router is judging that will give tacit consent to it after this active router lost efficacy can recover rapidly, and continues to transmit data message to it, and does not carry out data redirection.This scheme can be limited in the influence that single point failure caused of network in the relatively little scope, can avoid network concussion and loss of data.
Yet, in realizing process of the present invention, the inventor finds that there are the following problems at least in the prior art: neighbor router can't judge that active router is " soft start " or " hard reboot ", when active router lost efficacy owing to some expendable bust, then its neighbor router is still constantly transmitted data message to it, then causes data message to be lost; And heat needs to carry out communication between a large amount of plates in the process fully.

Fig. 2 is the flow chart of system hot standby processing method embodiment two of the present invention, and as shown in Figure 2, present embodiment provides a kind of system hot standby processing method, can specifically comprise the steps:
Step 201 is divided according to state level and priority the internal state of self respectively from management board and main management plate, and generates respectively from the State Summary catalogue of management board and the State Summary catalogue of main management plate.
In the present embodiment, main management plate and adopt the mode of synchronous operation, i.e. main management plate and all receive protocol massages from neighbours from management board from management board.This step generates corresponding State Summary catalogue for principal and subordinate's management board respectively according to self state, particularly, the main management plate is divided according to state level and priority main management intralamellar part state, make up the State Summary catalogue of main management plate, from management board main management intralamellar part state is divided according to state level and priority, made up State Summary catalogue from management board.Wherein, the content of State Summary catalogue can comprise the State Summary value of state index and each state index correspondence.This step can adopt digest algorithm that different state informations is converted into one section condition code, i.e. State Summary value, and digest algorithm herein can specifically adopt Message Digest Algorithm 5 (Message Digest Algorithm 5; Hereinafter to be referred as MD5) algorithm, perhaps adopt verification and (checksum) digest algorithm etc.In this step, principal and subordinate's management board is when generating each self-corresponding State Summary catalogue, can divide internal state separately according to state level and priority, make up the state catalogue with this, each state directory entry is represented its summary status of all subitems down respectively.In the present embodiment, the State Summary value of every grade of node is the State Summary value sum of the next stage child node of described node in the State Summary catalogue.State Summary catalogue in the present embodiment is a tree structure, forms hierarchical structure by the State Summary catalogue with the main management plate or from the state of management board; From the root node of State Summary catalogue, the state of root node reflects whole state of a process; The State Summary value sum of all child nodes of root node next stage is the State Summary value of this root node; By that analogy, the State Summary value of every grade of node is the summation of State Summary value of the next stage child node of this node.When carrying out the contrast of two State Summary catalogues, by one-level level comparison, can find the nonsynchronous node of state of minimum zone, the state of this node correspondence is carried out can solving nonsynchronous situation synchronously.
In order to be illustrated more clearly in the generative process of State Summary catalogue in the present embodiment, present embodiment is with (the Open Shortest Path First that generates that Open Shortest Path First; Hereinafter to be referred as: OSPF) the State Summary directory process of Routing Protocol module is that example describes.Fig. 3 is the schematic diagram of the State Summary catalogue among the system hot standby processing method embodiment two of the present invention, as shown in Figure 3, the state of this OSPF Routing Protocol module eight grades have been divided, i.e. OSPF top-level root catalogue, OSPF example list, OSPF example, OSPFarea, ospf interface tabulation, ospf interface and ospf neighbor and status list thereof.Wherein, OSPF top-level root catalogue has been represented whole OSPF module, stores the State Summary of the whole OSPF module of representative under this catalogue.The next stage summary of OSPF top-level root catalogue is OSPF example list summary, the OSPF example list is being represented the state information summary status summary of OSPF instance number and each example, and this grade State Summary is represented the summary that gathers of OSPF example 1, OSPF example 2 and 3 three example state summaries of OSPF example.Wherein, the OSPF example is the entity of independent operating ospf protocol logically, is similar to independent O SPF entity physically.By that analogy, the subordinate of OSPF example list summary is respectively the State Summary of each OSPF example.And the next stage of each OSPF example summary is ospf area (area) summary, and this grade OSPF area summary is represented the state of OSPF area 0, OSPF area 1 and OSPF area 2.Wherein, OSPF area is the area concept that defines in the ospf protocol, is used to divide ospf network, to reach the effect of stratification ospf network.The next stage summary of OSPF area is ospf interface tabulation summary, and this ospf interface list state summary is represented the state of ospf interface 1, ospf interface 2 and ospf interface 3.Wherein, ospf interface refers to participate in the logic interfacing of ospf protocol operation.And the next stage summary of ospf interface tabulation is each ospf interface State Summary, and each ospf interface State Summary is represented the state of each ospf interface respectively.At last, ospf neighbor and status list thereof summary is represented the neighbours under the ospf interface and the state information of status list thereof etc.Wherein, ospf neighbor refers to the ospf adjacency peer-to-peer found on ospf interface.
Step 202, from management board to generate according to oneself state self the State Summary catalogue and the State Summary catalogue of the main management plate that obtains safeguard processing.
Main management plate in the present embodiment only is responsible for generating the State Summary catalogue of self, i.e. the State Summary catalogue of main management plate in running; And from management board except the State Summary catalogue that be responsible for to generate self, also obtain the State Summary catalogue of main management plate simultaneously.The main management plate sends to the State Summary catalogue of this main management plate from management board after generating the State Summary catalogue of main management plate according to the state of main management plate.From management board to obtain self the State Summary catalogue and the State Summary catalogue of main management plate safeguard processing, promptly preserving the State Summary catalogue of self and the State Summary catalogue of main management plate simultaneously from management board this locality.
Step 203, whether consistent with the State Summary catalogue of described main management plate from management board according to described self the State Summary catalogue of preset trigger condition judgment, if, then return execution in step 202, otherwise execution in step 204.
In the present embodiment, main management plate and adopt the mode of synchronous operation from management board, promptly main management plate and all receive protocol massages from neighbours from management board is then similar with the main management plate from management board, also can obtain correct external information.In theory, if the main management plate with obtain identical input information from management board, and adopt the mode of synchronous operation to move, then output result of Chan Shenging and state are also with identical.Yet, because main management plate and can't reach in full accord the ideal from the sequential of management board inside and ambient conditions, may exist certain data transmit-receive to postpone, as the main management plate and from time of management board receiving data packets may be inequality, from management board the inconsistent situation of state with the main management plate appears probably running then.Therefore, present embodiment is from State Summary catalogue and the State Summary catalogue of main management plate when safeguarding of management board to self, come the State Summary catalogue of self and the State Summary catalogue of main management plate are compared according to the preset trigger condition from management board, judge that the two is whether consistent, find the main management plate and from the inconsistent situation of the state of management board with this.
Particularly, the preset trigger condition can be specially when detect described self State Summary catalogue from management board and change in the present embodiment, maybe when the State Summary catalogue that receive the described main management plate that described main management plate sends from management board.Be that this step can be specially when detecting described self State Summary catalogue from management board and change, judge whether the State Summary catalogue of self is consistent with the State Summary catalogue of main management plate; If consistent with the State Summary catalogue of main management plate from the State Summary catalogue of management board self, then return execution in step 202, continue the State Summary catalogue of self and the State Summary catalogue of main management plate are safeguarded; If inconsistent from the State Summary catalogue of the State Summary catalogue of management board self and main management plate, then execution in step 204, start a synchro timer.Perhaps be specially when receiving the State Summary catalogue of the described main management plate that described main management plate sends from management board, judge whether the State Summary catalogue of self is consistent with the State Summary catalogue of main management plate; If consistent with the State Summary catalogue of main management plate, then return execution in step 202 from the State Summary catalogue of management board self; If inconsistent from the State Summary catalogue of the State Summary catalogue of management board self and main management plate, then execution in step 204, start a synchro timer.
Step 204 starts synchro timer from management board.
In the present embodiment, main management plate and from having certain state delay between the management board receives certain protocol massages earlier as the main management plate, causes the state of main management plate that change has taken place; And do not receive this protocol massages simultaneously from management board, and its this protocol massages that in time of delay, is untreated, then the state from management board does not change.Perhaps earlier certain protocol massages is handled, and upgraded the State Summary catalogue of self from management board, and main management plate this message that also is untreated, its state does not change.This shows main management plate and State Summary catalogue inconsistent temporarily that may cause principal and subordinate's management board from the state delay between the management board.For fear of main management plate and state delay from existing between the management board, if present embodiment is through judging from the State Summary catalogue of the State Summary catalogue of management board self and main management plate when inconsistent, start a synchro timer from management board, postpone a period of time by synchro timer and carry out state synchronized again.Specifically can be in advance the timing of synchro timer be set according to the main management plate and from the state delay time between the management board.
Step 205 judges from management board whether synchro timer is overtime, if then execution in step 208, otherwise execution in step 206.
, after starting synchro timer, the timing of this synchro timer is safeguarded from management board, judged whether this synchro timer is overtime.Within the timing of synchro timer, promptly when judging that from management board synchro timer is not overtime, then execution in step 206, and it is consistent with the State Summary catalogue of described main management plate to continue to judge whether to detect described self State Summary catalogue from management board; When the timing of synchro timer arrives, when promptly synchro timer was overtime, then execution in step 208, with described self state and the state of described main management plate carry out synchronously.
Step 206, it is consistent with the State Summary catalogue of described main management plate to judge whether to detect described self State Summary catalogue from management board, if then execution in step 207, otherwise continues execution in step 205.
Before synchro timer is overtime, continue to judge that from management board the State Summary catalogue that whether detects self in timing is consistent with the State Summary catalogue of main management plate.If detecting the State Summary catalogue of self in timing becomes consistent from management board again with the State Summary catalogue of main management plate, then execution in step 207, cancel this synchro timer, and cancellation is to described self the state synchronization processing of state and described main management plate, otherwise continue execution in step 205, overtime up to the timing of this synchro timer.If it is consistent that the State Summary catalogue that does not detect self from management board in timing and the State Summary catalogue of main management plate become, then with described self state and the state of described main management plate carry out synchronously.
Step 207 is cancelled described synchro timer from management board, and cancellation is to described self the state synchronization processing of state and described main management plate.
Before synchro timer is overtime, when the State Summary catalogue that detects self from management board in timing and the State Summary catalogue of main management plate become again when consistent, cancel described synchro timer from management board, and cancellation is to described self the state synchronization processing of state and described main management plate, so just, avoided from the state synchronized between management board and the main management plate, eliminated the main management plate and from the state delay between the management board.
Step 208, from management board with described self state and the state of described main management plate carry out synchronously.
When inconsistent from the State Summary catalogue of the State Summary catalogue of management board self and described main management plate, and the synchro timer that starts is overtime, and the State Summary catalogue that does not detect self from management board is consistent with the State Summary catalogue of main management plate, then from management board with described self state and the state of described main management plate carry out synchronously.Usually, if principal and subordinate's management board has on all four input, then their final states are also with unanimity, thus the synchro timer in the present embodiment always is in startup, in the repetitive process cancelling, cancel, start.Yet, after starting synchro timer, as if the inconsistent situation that the follow-up operation process, can't eliminate this state from management board, then receive the state information of managing independently plate from management board, and according to the state information of main management plate with self state synchronized to the state of main management plate, be consistent with the state of guaranteeing principal and subordinate's management board.
In the present embodiment, because the message of principal and subordinate's management board input is identical, the state of the two generation also is consistent in theory, do not need to carry out restorative synchronous, communication in this process between principal and subordinate's management board mainly is the synchronous communication of state catalogue summary, the traffic of its generation is very little, does not influence the operation of main management plate basically, and its efficient can not reduce yet.In case the nonsynchronous situation of master slave mode takes place, carry out state information when synchronous as long as carry out synchronously to nonsynchronous state content takes place.Such as ospf protocol, make in mode shown in Figure 3 and to build the state catalogue, suppose that other state is all consistent, and only be that neighbor list and state thereof under certain interface is unlikely, so as long as carry out synchronously at neighbor list this interface under and state thereof, the required communication information amount of this synchronizing process is just very little.The technical scheme that the complete heat of in the prior art other is equipped with, do not move from management board, do not receive protocol massages yet, all switching take place information that the back relied on all by the main management plate to sending from management board, it is huge that it keeps the required amount of information of operation, may cause the congested of communication between plate, and the adverse consequencess such as operational efficiency reduction of route protocol module on the main management plate.And, will postpone could obtain for a long time to switch the required data message in back from management board if caused between plate communication congested, this has just increased the mortality that switches when taking place.This shows that present embodiment can reduce communication between the hot plate that is equipped with in the process to greatest extent than the scheme of prior art, increases principal and subordinate's management board success rate for switching.In addition, in the present embodiment, for real work main management plate, under the situation of having opened the NSR function, the main management plate only carries out the generation and synchronously of the State Summary catalogue of self generally speaking, can not produce a large amount of cpu resource consumption like this, and do not need block type with data sync to from management board, the operational efficiency of main management can not reduce like this, so present embodiment has higher efficient.
