Problems solved by technology

[0004] In the existing technology, Ethernet OAM is located on the second layer, while BFD is located on the third layer. The flexibility and scalability of the application are limited, and it increases the difficulty for upper-layer system users to understand the two protocols of OAM and BFD, thereby improving the System Vendor Development Costs

Abstract

The invention discloses an Ethernet OAM and BFD dual-stack processing engine realization method and device; the method comprises the following steps: a, receiving a message; b, parsing and determining message types, and if the message is an OAM message or BFD message, entering steps c and d, if not, entering a step e; c, transferring the message to a dual-stack processing engine for reception process; d, transferring the message to the dual-stack processing engine for emission process; e, sending out the message. The Ethernet OAM and BFD dual-stack processing engine is nested in a chip, so the OAM message and BFD message can be processed in the dual-stack processing engine, thus enlarging great flexibility and expandability on one hand, and reducing understand difficulty of an upper level system for two protocols on the other hand, finally reducing system manufacturer exploitation cost and accelerating novel product releasing time.

Description

technical field [0001] The invention relates to the field of network communication, and in particular, to a method and device for realizing an Ethernet OAM and a BFD dual-stack processing engine. Background technique [0002] The Ethernet OAM (Operations, Administration and Maintenance) technology was originally proposed by IEEE 802.1ag, ITU-Y.1731, and is used to monitor, locate, and report errors on service channels at various levels in Ethernet. [0003] Later, IETF proposed the use of BFD (Bidirectional Forwarding Detection, bidirectional forwarding detection) based on IP as an OAM technology. BFD is more flexible in the use of sending time intervals, and supports functions such as negotiation and modification. The traditional Ethernet OAM is different, and the general use precision is millisecond level. [0004] In the prior art, the Ethernet OAM is located at the second layer, while the BFD is located at the third layer. The flexibility and scalability of the applicat...
