Abstract

Disclosed in the invention are a method and an apparatus for processing microcode table items hierarchically, which relate to the field of communications. The method comprises the following steps: setting a first level microcode table, a second microcode table and a third microcode table suitable for different services in a network; in the process of searching a forwarding table items, searching the first microcode table or the second microcode table according to the forwarding table results of different services; determining, according to the searching results of the first microcode table or the second microcode table, the search of a next level table item until an outlet and encapsulation information are found. By processing microcode table items hierarchically, the invention can make the drive update operation of the microcode table items simple, and enables fast switching when the service is under protection especially under multi-level protection.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a device for hierarchically processing network processor microcode entries. Background technique [0002] Telecom operators require metro transmission networks to provide more flexible network topologies including point-to-point and point-to-multipoint, provide multi-service carrying capacity to achieve heterogeneous intercommunication, and provide carrier-level protection switching. In order to meet the requirements of long-term evolution Technology (Long Term Evolution, referred to as "LTE") needs to support Layer 2 Virtual Private Network (Layer 2Virtual Private Network, referred to as "L2VPN") bridging Layer 3 Virtual Private Network (Layer 3Virtual Private Network, referred to as "L3VPN") etc. In order to meet the various needs of operators, the device needs to support common layer 2 routing, common layer 3 routing, L2VPN, L3VPN, end-to-end pseudowire emulation (Pseud...
