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 present invention relates to a programmable implementation method of SCL KEY. The method comprises the following steps: step 1, the user configures the keyword type of the selection message; step 2, obtains a flexible A keyword template; Step 3, generating a flexible keyword through the flexible keyword template; Step 4, updating the SCL KEY based on the flexible keyword. The present invention selects a field of any position and length in a message through a flexible keyword template to obtain a flexible keyword, and updates the SCL KEY to obtain the SCL KEY, which can realize the flexible programming of the SCL KEY without affecting the logic of the original chip SCL KEY.

Description

technical field [0001] The invention relates to the technical field of network switching chip design, in particular to a programmable realization method of a network chip SCL KEY. Background technique [0002] When the network switching chip is designed, the network service list (Service Classify List, SCL) module will be used to classify the packets. For example, the tunnel packets need to be decapsulated, and the Vlan in the packets needs to be converted. However, SCL needs to match specific fields in the packets to correctly classify the packets, that is, only packets matching the corresponding fields can be processed accordingly. [0003] At present, the key type (KeyType) is pre-designed in the chip, and different fields of the message are selected according to different key types (KeyType). For example, to decapsulate virtual extended local area network (Vxlan) tunnel packets, the chip will design the key type (KeyType) as virtual extended local area network (Vxlan), ...
