Embodiment Construction

[0043] like figure 2 As shown, the VLAN information transmission method includes: when sending VLAN information, the VLAN information includes an effective VID determined according to one or more virtual local area network identification (VID) selection rules, or, when sending VLAN information, the VLAN information It includes the types of one or more VID selection rules and the parameters used by each VID selection rule to indicate the VID selection range.

[0044] The VLAN information is information configured for one or more combinations of device nodes, aggregated interfaces, sub-interfaces, and cross-rack aggregated identifiers (D-LAG-ID); the VLAN information includes device node , aggregated interface, sub-interface, cross-rack aggregated ID (D-LAG-ID) and one or more information.

[0045] The VID selection rule is an inclusion rule, a parity rule, or an exclusion rule;

[0046] The inclusion rule is used to indicate that the VID indicated by this rule is valid, and ...

Abstract

The invention discloses an information transmission method and an information transmission device of a virtual local area network. The method comprises the following steps that when information of the virtual local area network is sent, the information of the virtual local area network comprises a valid VID (virtual local area network identify) which is determined in accordance with one or a plurality of VID selection rules, or the information of the virtual local area network comprises types of one or a plurality of VID selection rules and parameters of all of the VID selection rules for indicating the selection range of the VID. Through comprehensive application of rules including an inclusion rule, an odd-even rule or an exclusion rule, the configuration of the information of the virtual local area network (VLAN) is simplified, the combination with a node, an aggregation interface, a subinterface and a distributed link aggregation identify (D-LAG-ID) is performed, so that traffic flow can be flexibly distributed, the continuous VLAN information is compressed during encoding, special encoding is performed on different information, and the information flow is reduced during protocol interaction.

Description

technical field [0001] The invention relates to data communication technology, in particular to a virtual local area network (VLAN) information transmission method and device. Background technique [0002] like figure 1 What is shown is a distributed Link Aggregation Group (LAG) system based on the Link Aggregation Control Protocol (LACP) technology specified in the 802.1AX standard. Some new features appear in the system, one of the important features is to protect the network part at the interconnection interface, not to block some ports, to fully utilize the bandwidth of the network, and to meet the requirements of protection, load balancing, and redundancy. [0003] from figure 1 You can see that there is a service gateway interface, which is used to determine how the business flow is forwarded. The basis of the judgment is to obtain relevant information, but at present, it is only known that the forwarding is performed according to the VLAN, and the configuration met...
