Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] In one embodiment, a switch is provided. According to the OSI (Open System Interconnect) seven-layer model, the switch can be divided into a second-layer switch, a third-layer switch, etc., up to a seventh-layer switch. Take a Layer 2 switch working based on a Mac (Media Access Control, Media Access Control) address as an example. In a Layer 2 switch, there is a Mac address, Vlan (Virtual Local Area Network, Virtual Local Area Network) information, and an address for storing port information. Table, the switch uses the source Mac address and Vlan information of the received signal to look up...

Abstract

The invention provides an address table storage and lookup method, applied to a switch. The method comprises the following steps: receiving an address table query instruction; parsing the address table query instruction to obtain an Mac address and Vlan information to be looked up; querying a mapping address corresponding to the address table query instruction according to the Mac address and the Vlan information; and querying port information corresponding to the address table query instruction in a preset multi-layer chain table according to the mapping address, wherein the port information and the mapping address that corresponds to the port information are stored in the preset multi-layer chain table. The invention also provides an address table storage and lookup device, computer equipment and a readable storage medium. According to the invention, after an address table query instruction is received, the query instruction is parsed to acquire the Mac address and the Vlan information, the corresponding mapping address is queried, and the port information is queried in the preset multi-layer chain table to ensure that the retrieval for the Mac address and the Vlan information can be quickly performed, and the lookup speed can be increased.

Description

technical field [0001] The invention relates to network communication technology, in particular to an address table storage and search method, device, computer equipment and readable storage medium. Background technique [0002] With the development of computer and communication technology, computer network technology represented by the Internet has developed rapidly, which not only greatly enriches the content and form of information, but also provides more possibilities for information exchange and resource sharing. But at the same time, the transmission and exchange speed of Ethernet data often restricts the development of Ethernet, requiring higher performance network equipment to increase the speed of the network. [0003] As an important layer 2 switching network device, a switch directly affects the overall network speed of the network where it is located. In a layer 2 switch, the address table lookup speed of the switching chip is an important factor determining the ...
