According to, the corresponding critical data of IPCP agreement, the corresponding critical data of IPV6CP agreement, the corresponding critical data of MPLSCP agreement,
The corresponding critical data of OSINLCP agreement, PAP agreement and the corresponding critical data of CHAP agreement etc..
Interface index is the unique identification of interface, and the interface index of same communication equipment be it is unique, primary master control and
The interface of spare master control common user communication equipment, thus primary master control can be set in advance as with the interface index of spare master control it is consistent
's.
Mark is updated, each agreement corresponding one updates mark in the first data mapping tables, corresponding for tag protocol
Whether critical data has update, and critical data has the agreement of update to need the data of update being synchronized to spare master control, primary master
Control will update flag set before the data of update are synchronized to spare master control, in primary master control that the data of update are synchronous
To after spare master control, the set is removed.
Step S130, spare master control store received first data mapping tables to the second data mapping tables.
Received first data are reflected the first data mapping tables active push to spare master control, spare master control by primary master control
Firing table is stored to the second data mapping tables, completes synchronizing process with this.
A record in second data mapping tables can include: interface index (interface ID), the corresponding key of LCP agreement
The corresponding crucial number of data, the corresponding critical data of IPCP agreement, the corresponding critical data of IPV6CP agreement, MPLSCP agreement
According to, the corresponding critical data of OSINLCP agreement, PAP agreement and the corresponding critical data of CHAP agreement etc..
Whether step S140 judges in the second data mapping tables comprising the corresponding critical data of LCP agreement.
Spare master control stores the first data mapping tables to the second data mapping tables, judges each in the second data mapping tables
It whether include the corresponding critical data of LCP agreement in the critical data of the ppp protocol of interface, if respectively being connect in the second data mapping tables
Include the corresponding critical data of LCP agreement in the critical data of the ppp protocol of mouth, advances to step S150；If the second data are reflected
Do not include the corresponding critical data of LCP agreement in the critical data of the ppp protocol of each interface in firing table, advances to step S160.
Step S150, spare master control restore LCP agreement according to the corresponding critical data of LCP agreement.
If in the second data mapping tables including the corresponding critical data of LCP agreement, spare master control is assisted according to the LCP of each interface
Corresponding critical data is discussed, sets consistent with critical data in the second data mapping tables for the parameter of the LCP of corresponding interface
The LCP agreement of each interface of spare master control is reverted to the consistent configuration of primary master control corresponding interface LCP agreement by data, in order to
When primary master switching to spare master control, LCP agreement had with the consistent protocol negotiation parameter of the communication equipment of link opposite end,
The LCP ECHO link keep-alive request message that link opposite equip. interface can be responded, so that local terminal and opposite end link processing keep-alive
State, link not will disconnect, and business datum also normally forwards.
Step S160, spare master control do not restore LCP agreement.
Step S170, in primary master switching to spare master control, configuration data assists PPP based on the received for spare master control
The configuration data of view is restored.
In primary master switching to spare master control, spare master control is matched according to the allocation data recovering ppp protocol of storage

Step S200, spare master control do not restore NCP agreement.
Embodiment 2
Fig. 2 a to Fig. 2 b is a kind of flow diagram for active and standby method for synchronously switching that second embodiment of the invention proposes.
This method is applied to support that the communication equipment of ppp protocol, the communication equipment include two master controls, and a master control is
Primary master control, another master control are spare master control, and the ppp protocol includes LCP agreement and NCP agreement, and the NCP agreement includes
IPCP agreement, IPV6CP agreement, MPLSCP agreement and OSINLCP agreement.
The ppp protocol further includes authentication protocol, and the authentication protocol includes PAP agreement and CHAP agreement.
In the present embodiment, the communication equipment can be the routing device of support ppp protocol, gateway etc..
The communication equipment includes that at least one supports ppp protocol interface, is connect for the interface with other communication equipments
To realize the communication between two communication equipments.
Method includes the following steps:
Step S210, two master controls are held consultation with the primary master control of determination and spare master control, and to primary in communication equipment
Master control and spare master control are initialized respectively.
Before communication equipment initialization, the negotiations process of primary master control and spare master control can be carried out in advance, it is primary with determination
Master control and spare master control, the data transmitted between two communication equipments are sent to the processing that primary master control carries out next step.
Primary master control and spare master control are according to negotiation as a result, being respectively completed the work of primary master control and spare master control.
In initialization, primary master control and spare master control are respectively completed respective initialization.
Step S220, primary master control configure ppp protocol, by matching for the order for having executed operation in ppp protocol
It sets data and is synchronized to spare master control.
In order to avoid the protocol configuration of ppp protocol and the critical data appearance of ppp protocol are inconsistent, primary master control will be defined
The configuration data for needing to save is synchronized to spare master control, the configuration data not saved clearly, asynchronous to arrive spare master control.
Further, the configuration data for clearly requiring preservation can be the corresponding PPP of order for having executed operation
The configuration data of agreement.
Configuration is generally saved on communication equipment, is to need operator clearly to execute configuration and save to order currently to match to save
It sets.For example, if current-configuration need to be saved, when executing write command operation, then can be saved when being configured to ppp protocol
Execute the configuration data of ppp protocol current when the write command, i.e. operator's current-configuration clearly to be saved；Do not hold
The write that went operation, also just without clearly to save configuration.
Ppp protocol is configured in primary master control, the ppp protocol of the order of operation will have been executed in primary master control
Configuration data is synchronized to after spare master control, before primary master switching to spare master control, if the configuration of the ppp protocol occurs
Variation, changed configuration data is also synchronized to spare master control by primary master control, so that primary master control and spare master control are matched
Set data realtime uniform.
Step S230, primary master control acquires the critical data of the ppp protocol of each interface, and critical data is stored to
One data mapping tables.
Primary master control is previously stored with the first data mapping tables, and the original records in first data mapping tables can be
Ppp protocol critical data when primary master control initializes.
For example, following table is the example of the critical data of acquisition.
In upper table, the negotiation option data of LCP agreement acquisition includes Magic value and opposite end MRU, and Magic value is for identifying
Whether LCP message is what oneself sent, and checks that link whether there is loop, after the completion of LCP negotiates, the meeting of ppp link both ends
LCP ECHO message interaction is carried out, realizes keepalive feature.Therefore to the front and back of spare master control, Magic is needed primary master switching
If approving jointly by the negotiation of ppp link both ends, however there is no GR standards for ppp protocol, cannot renegotiate disconnection
Under the premise of ppp link business datum forwards, that is, need configuration, the critical data etc. between primary master control and spare master control
The synchronization of data, after guaranteeing primary master switching to spare master control, the Magic value that ppp link local terminal uses be by with opposite end
Negotiate approval.
Others negotiate option data, have the synchronous reason similar with above-mentioned Magic value, no longer describe one by one here.
After configuration data is synchronized to spare master control by primary master control, the ppp protocol in primary master control start carry out LCP and
NCP negotiates, and when the negotiation state of LCP and NCP changes between Opened state and Not Opened state, acquisition is every
The critical data of the ppp protocol of one interface.
It stores by the critical data of the ppp protocol of each interface to the first data mapping tables, while advancing to step
S240 and step S260.
Step S240, after primary master control and spare master control successful connection for the first time, primary master control is by the first data of storage
Mapping table is pushed to spare master control.
Spare master control is reliably connected request after primary master control initialization to primary master control initiation and begins listening for being reliably connected
Request, listen to from spare master control be reliably connected request after, with spare master control foundation be reliably connected.
In the present embodiment, spare master control can periodically be initiated to be reliably connected request, until between primary master control can
By successful connection.
The second data mapping tables are previously stored in spare master control, primary data may include spare in the second data mapping tables
The critical data of ppp protocol when master control initializes.
After primary master control and spare master control successful connection for the first time, primary master control actively pushes the first data to spare master control
Mapping table, the specific steps are as follows:
The total interface of first data mapping tables of primary master control traversal current cache corresponds to the critical data of agreement, does not examine
Look into update mark.
If not having critical data in the first data mapping tables of current cache, the mapping of the first data is pushed to spare master control
The message that table empties, spare master control receive the message that the first data mapping tables empty, will cached in spare master control immediately
Two data mapping tables empty, while checking in the second data mapping tables whether there is the corresponding critical data of LCP agreement, if there is LCP
LCP agreement is reset to init state by the corresponding critical data of agreement.
If the critical data for having interface to correspond to agreement in the first data mapping tables of current cache, pushes away to spare master control
The critical data for sending the first data mapping tables total interface to correspond to agreement will after spare master control receives the first data mapping tables
All the elements are stored to the second data mapping tables in first data mapping tables.
Step S250, spare master control store received first data mapping tables to the second data mapping tables.
Step S260, judges whether the negotiation state of the corresponding ppp protocol of the interface of primary master control changes.
It stores by the critical data of the ppp protocol of interface to the first data mapping tables, primary master control also judges interface
Whether the negotiation state of corresponding ppp protocol changes, preceding if the negotiation state of the ppp protocol of the interface changes
Proceed to step S270；If the negotiation state of ppp protocol does not change, step S300 is advanced to.
Further, the protocol negotiation state changes including being converted to Opened state from Not Opened state
Not Opened state is converted to from Opened state.
Since the expression of Not Opened state is being held consultation, there is no progress, primary master control is cut for corresponding data forwarding
When shifting to spare master control, data forwarding will not influence, therefore, the critical data of Not Opened state, it is not necessary to need to be synchronized to
Spare master control reduces data volume that is synchronous and restoring, avoids simultaneously compared to the scheme that all data are synchronized to spare master control
Configuration data and the inconsistent situation of critical data, because the configuration of primary master control may not save and be synchronized to spare master
Control.
Step S270, the critical data of the ppp protocol of primary master control acquisition interface update the according to the critical data of acquisition
One data mapping tables, and flag set will be updated.
It further include updating mark in first data mapping tables.
In the LCP and NCP of the ppp protocol of the interface, in TLU, (This-Layer-UP, corresponding negotiation state are from Not
Opened state is converted to Opened state) and TLD (This-Layer-Down, corresponding negotiation state are to turn from Opened state
Be changed to Not Opened state) movement when, acquire the critical data of the ppp protocol of the interface.
The first data mapping tables are updated according to the critical data of the ppp protocol of the interface of acquisition, and the first data are mapped
Flag set is updated in table.The set indicates that the critical data of corresponding agreement has update.
For example, following table is the example of the first data mapping tables.
As shown above, LCP agreement, IPCP agreement, the IPV6CP agreement of interface A has update to indicate, the negotiation of agreement
State is Opened, can indicate that the LCP agreement, IPCP agreement, IPV6CP agreement of interface A just negotiates to complete, also will not more
New data is synchronized to spare master control, and primary master control can push away LCP agreement, IPCP agreement and the corresponding critical data of IPV6CP agreement
It is sent to spare master control, after pushing successfully, removes the set for updating mark；MPLSCP agreement, the OSINLCP agreement of interface A does not have
Mark is updated, protocol negotiation state is Opened, can indicate that the MPLSCP agreement of interface A, OSINLCP agreement have been negotiated
