Problems solved by technology

When the new network protocol needs to use the SCL module, it is necessary to select the message field concerned by this protocol. However, because the corresponding KeyType is not pre-designed, the new network protocol cannot be used in the existing network chip, which greatly reduces the use of the chip. life

Abstract

The invention relates to a programmable implementation method of an SCL KEY. The method comprises the following steps: 1, a user configuring and selecting a keyword type of a message; 2, obtaining a flexible keyword template according to the keyword type of the selection message; 3, generating a flexible keyword through the flexible keyword template; and 4, updating the SCL KEY based on the flexible keyword. According to the invention, the flexible keyword template is used for selecting the field with any length at any position of the message to obtain the flexible keyword, and the SCL KEY isobtained by updating, so that the flexible programming of the SCL KEY can be realized on the basis of not influencing the logic of the original chip SCL KEY.

Description

Technical field[0001]The present invention relates to the technical field of network switching chip design, in particular to a programmable realization method of the network chip SCL KEY.Background technique[0002]When designing a network switching chip, a network service list (Service Classify List, SCL) module is used to perform service classification processing on messages. For example, tunnel messages need to be decapsulated, and VLANs in the messages need to be converted. However, SCL needs to match specific fields in the message to correctly classify the message, that is, only the message that matches the corresponding field can be processed accordingly.[0003]Currently, the key type (KeyType) is designed in the chip in advance, and different fields of the message are selected according to different key types (KeyType). For example, when the virtual extended local area network (Vxlan) tunnel message is decapsulated, the chip will design the key type (KeyType) as the virtual exte...
