Embodiment Construction

[0021] Such as figure 1 Shown, a kind of UP MEP message processing method comprises steps:

[0022] S200: Analyze the OAM message in the switch chip to obtain necessary OAM information.

[0023] In the Parser (analysis) module of the switch chip, the OAM message is parsed, and the necessary OAM information is obtained, and the information is passed to the IGP (Ingress Process, entry process), EGP (Egress Process, exit process) module. Specifically, there are multiple types of OAM messages, which mainly include BFD messages and CCM messages, and different types of OAM messages have different necessary OAM information. Specifically, when the OAM message is a BFD message, obtain yourDiscrimination information, and when the OAM message is a CCM message, obtain mel, megId, and mepId information.

[0024] S400: Identify the fast OAM message in the OAM message according to the necessary OAM information.

[0025] The IGP module adds OAM packet type distinction, and distinguishes fa...

Abstract

The present invention provides a method and system for processing UP MEP messages, which analyze the OAM messages in the switching chip, obtain necessary OAM information, and identify the fast OAM messages in the OAM messages according to the necessary OAM information, for fast The OAM message performs the UP MEP lookup table operation, obtains the address of the UP MEP, and modifies the destination port address of the fast OAM message to the OAM engine, reads the corresponding data in the preset database according to the address of the UP MEP, and combines it with the MEP state for OAM operations. In the whole process, identify the fast OAM message in the OAM message, perform a lookup table operation on the fast OAM message, put the UP MEP lookup in the packet switching process, reduce the burden of the lookup table on the OAM engine, and improve the processing speed , realizing efficient processing of UP MEP packets.

Description

technical field [0001] The present invention relates to the technical field of computer communication, in particular to a UP MEP (Maintenance association End Point, Maintenance End Point) message processing method and system. Background technique [0002] Ethernet technology has been widely used due to its good economy, interoperability and ease of use. Carrier Ethernet has become an important research field of current network technology. Carrier Ethernet must provide functions such as good service management, fault detection, and performance monitoring, and the core of this function is OAM (Operation Administration and Maintenance). [0003] In recent years, as the MPLS (Multi-Protocol Label Switch, Multi-Protocol Label Switching) technology matures and is widely used in the field of transmission networks, the PTN technology has been adopted by more and more operators. IETF (Internet Engineering Task Force, Internet Engineering Task Force) expands the original MPLS technol...
