Problems solved by technology

In this way, for each type of data for different purposes, such as IP packets, etc., it takes a lot of coding space to make coding judgments, thus occupying a large amount of coding space
Moreover, with the rise of Ethernet OAM (Operation Administration Maintenance, operation, maintenance and management), the types of messages for different purposes and other data information are still increasing at a high speed, so that the corresponding demand for coding space continues to increase, which not only makes the data The encoding space at the forwarding level is increasing, and the efficiency of finding data information for different purposes is decreasing

Embodiment Construction

[0023] A data processing method and device provided in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The search engine mentioned in the following embodiments may be TCAM (Ternary Content Addressable Memory, ternary content addressable memory).

[0024] Such as figure 1 As shown, a data processing method provided by an embodiment of the present invention, the method includes:

[0025] 101: Receive data information; for example: when the data forwarding plane receives an Ethernet message, the data forwarding plane can receive it through an Ethernet port.

[0026] 102: Acquiring the key field of the data information; wherein, the key field is used to distinguish the data information; for example: when the data forwarding plane receives the Ethernet message, obtaining the key field of the data information is to obtain The destination MAC address of the Ethernet packet;

[0027] 103: According to the key f...

Abstract

The embodiment of the invention discloses a method and a device for processing data, and relates to the technical field of network communication. The method and the device solve the problems of large coding space for processing data of a data forwarding plane and low search efficiency in the prior art. The method for processing the data, provided by the embodiment of the invention, comprises the following steps of: receiving data information; acquiring key fields of the data information, wherein the key fields are used for distinguishing the data information; acquiring processing indications of the key fields of the data information in a data resolving table of a search engine according to the key fields of the data information; and correspondingly resolving the data information according to the processing indications of the data information. The method and the device not only can reduce the coding space for processing the data of the data forwarding plane, but also can greatly improve the search efficiency.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a data processing technology. Background technique [0002] At the data forwarding level, data processing needs to judge data attributes and types based on data information and forwarding control table items, and then jump to different branches for processing. The following takes the identification processing of the destination MAC (Media Access Control, Media Access Control) address of the Ethernet packet as an example to illustrate. [0003] For a message entering from an Ethernet port, first read the destination MAC address of the message to determine the type of the MAC address. If the destination MAC address of the received message is a unicast MAC address or a broadcast MAC address, then carry out normal bridge forwarding; if the destination MAC address of the received message is a multicast MAC address, then one by one Detect and compare the destination MAC...
