Embodiment Construction

[0033] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0034] In an embodiment of the present invention, a method for synchronizing a forwarding table, such as figure 1 As shown, the method includes:

[0035] Step 10, when performing synchronization, the synchronization initiator uses markup language to write a synchronization message, and then sends the synchronization message to the synchronization receiver; wherein, in the synchronization message, each tag is associated with a field in the forwarding table to be synchronized corresponding, and the value of each label is equal to the value of the field corresponding to the label;

[0036] Wherein, the identification information of the field may be represented by a field name of ...

Abstract

The invention relates to a synchronization method and system of a forwarding table. The synchronization method comprises the following steps of: compiling a synchronous message through using a markup language by a synchronous initiating terminal during synchronization, and then sending the synchronous message to a synchronous receiving terminal, wherein in the synchronous message, each label corresponds to a field in the forwarding table to be synchronized, and each label value is equal to a reading value of the field corresponding to the label; and resolving the received synchronous message by the synchronous receiving terminal, only synchronizing the values of the labels corresponding to the fields included in a local forwarding table to a local terminal in allusion to each resolved label. By virtue of the synchronous method and system, the expandability, the synchronous success rate, the flexibility and the compatibility of the forwarding table are improved, the redundancy of a code is reduced, the quantity of fault items generated due to unsuccessful synchronization on the forwarding table is reduced, and the speed of version upgrading is increased.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for synchronizing forwarding tables. Background technique [0002] A switch usually includes a master control and a line card. The master control refers to the core component responsible for the switching, control, monitoring, clock, management and other functions of the system. Each switch is configured with at least 1 master controller and a maximum of 2 master controllers. When two master controllers are configured, the two master controllers can work in the mode of 1+1 master / standby and 1:1 load sharing. The line card is the component responsible for the most basic forwarding function, and it can provide different optical and speed combinations according to different types. The forwarding table is the table required to realize the forwarding of Layer 2 / Layer 3 packets in the switch, including: MAC (Medium Access Control, Media Access Control Layer) table, host...
