Abstract

The invention discloses a method and device for layering microcode table entries, relating to the field of communication. The method comprises the following steps of: setting a first-level microcode table, a second-level microcode table and a third-level microcode table which are suitable for different services in a network; searching the first-level microcode table or the second-level microcode table according to the forwarding table results of different services in the forwarding table entry searching process; and determining search of a next level table entry according to the search result of the first-level microcode table or the second-level microcode table until an outlet and encapsulating information are found. By layering the microcode table entries, the microcode table entries are easy to drive and update, and quick switching is realized when a service is under protection, in particular under multi-level protection.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a method and device for hierarchical processing of network processor microcode entries. Background technique [0002] Telecom operators require metro transmission networks to provide more flexible network topologies including point-to-point, point-to-multipoint, etc., provide multi-service carrying capabilities to achieve heterogeneous interoperability, and provide carrier-class protection switching to meet long-term evolution Technology (Long Term Evolution, "LTE" for short) bearer requirements, need to support Layer 2 Virtual Private Network (Layer 2 Virtual Private Network, "L2VPN") bridging Layer 3 Virtual Private Network (Layer 3 Virtual Private Network, "L3VPN") and many more. In order to meet the various needs of operators, the equipment needs to support ordinary layer 2 routing, ordinary layer 3 routing, L2VPN, L3VPN, end-to-end pseudo wire emulation (Pseudo Wire Emulati...
