Embodiment bis-
With reference to Fig. 2, provided the network collocating method flow chart of the enterprise network that the embodiment of the present invention two provides.
In the embodiment of the present invention, each access device of enterprise network inside adopts the periodic method of synchronization, and therefore whether current access device can detect to reach and carry out the synchronous cycle.Wherein, the synchronous cycle can be set according to actual demand, as 2 seconds, all can within 1 minute, wait, and the embodiment of the present invention is not construed as limiting this.
If, reach the synchronous cycle, perform step 203; If not, do not reach the synchronous cycle, return to step 202, wait for the synchronous cycle that reaches.
Owing to there being a plurality of access devices in enterprise network, and LAN configuration information synchronous normally end-to-end in enterprise network, be other access devices of being synchronizeed with current access device of mentioning in the embodiment of the present invention, can be understood as is the opposite equip. of being synchronizeed with this current access device.
In the embodiment of the present invention, current access device can periodically carry out the detection of LAN configuration information of whole enterprise network and synchronous, therefore arrive synchronous all after dates, current access device can send the whole network comparison request message to other access devices in enterprise network (as the access device adjacent with this access device), this the whole network comparison request message, for the LAN configuration information of the whole network of other access device storages of acquisition request, then can obtain the LAN configuration information of corresponding the whole network from the whole network comparison response message of these other access device feedbacks.
Because LAN configuration information may have been stored a lot of configuration informations, therefore in order to reduce in comparison the waste to resource, and compare fast, can calculate in advance the MD5(Message-Digest Algorithm 5 of LAN configuration information, Message-Digest Algorithm 5) value, thus directly adopt the MD5 value to compare.Therefore the load of the whole network comparison response message of other access devices feedbacks, the content of carrying is to obtain the MD5 value of LAN configuration information of the whole network of its storage.Then adopt the MD5 value of current access device in the LAN configuration information of the whole network of this locality storage, compare with the MD5 value of the LAN configuration information of the whole network obtained, determine that whether two MD5 values are identical.
Wherein, MD5 is complete consistent for guaranteeing communication, is one of widely used hash algorithm of computer (being called again digest algorithm, hash algorithm).
If the LAN configuration information of the whole network of local storage is identical with the LAN configuration information of the whole network of other access device storages, returns to step 202, waits for that next cycle detects again.
If not, the LAN configuration information of the whole network of local storage is not identical with the LAN configuration information of the whole network of other access device storages, performs step 204.
And, the embodiment of the present invention is synchronous in order to carry out fast, the synchronizing process of LAN configuration information also current access device is carried out with other access devices simultaneously, be the MD5 value of the LAN configuration information of the load of the whole network comparison request message the whole network that can carry local storage, so that other access devices can synchronously carry out the comparison of LAN configuration information.Subsequent process is consistent with this step, and when sending a request message with response message, its load can be carried the content of asking of local storage.
Owing to can comprising a plurality of VLANs (Virtual Local Area Network, VLAN) in enterprise network, in the LAN configuration information of the whole network, can comprise the LAN configuration information of each local area network (LAN).
If current access device is different from the LAN configuration information of the whole network of other access devices, current access device can send local area network (LAN) comparison request message to other access devices, LAN configuration information for each VLAN of acquisition request, therefore can receive the local area network (LAN) comparison response message of other access device feedbacks, the load of this local area network (LAN) comparison requests/response messages, the content of carrying is VLAN ID (Virtual Local Area Network Identity, VLAN ID), MD5 value with the LAN configuration information of this VLAN.
Current access device can be determined the VLAN that the MD5 value is corresponding according to VLAN ID, therefore can detect the LAN configuration information that VLAN ID is identical, and whether its MD5 value in this locality storage is identical with the MD5 value of obtaining from other access devices.
Determine that due to above-mentioned the LAN configuration information of the whole network is different, now current access device is in local canned data, and the LAN configuration information of at least one VLAN is not identical with the LAN configuration information of the corresponding VLAN of other access device storages.
Owing to can configuring a lot of different contents such as strategy in each VLAN, therefore the configuration operations such as change repeatedly may have been carried out according to demand to the configuration information of VLAN in actual treatment, for operation is distinguished, for configuration operation each time records corresponding operation number in LAN configuration information.
Wherein, operation number can be configured to: VLAN ID+ device id+sequence number, as shown in table 1:
| B0-B3 | B4-B7 | B8-B11 |
| VLAN?ID | Device id | Sequence number |
