Problems solved by technology

[0005] To sum up, it can be seen that in the FPGA-based MPLS-TP OAM implementation scheme, the sending, receiving, and processing of MPLS-TP OAM packets are all completed by the FPGA, causing the FPGA to undertake most of the work of MPLS-TP OAM implementation. Many items and heavy tasks
Although the FPGA resources are fully utilized, it also increases the cost of the equipment

Abstract

The invention provides a method for sending messages. The method comprises the following steps: receiving MPLS-TPOAM (Multi-Protocol Label Switching-Transport Profile Operation Administration Management) configuration information through an MPLS-TPOAM module, and sending the configuration information and VLAN ID (Virtual Land Area Network Identifier) to an Ethernet OAM module; judging whether the configuration information is connectivity detection CV (Curriculum Vitae) frame enabling through the Ethernet OAM module, invoking a driver interface function for sending the Ethernet CV frame with appointed VLAN ID to the FPGA (Field Programmable Gate Array) through an exchange chip if the configuration information is the CV frame enabling, and converting the Ethernet CV frame into an MPLS-TPOAM message through the FPGA and sending the MPLS-TPOAM message out through the exchange chip. The invention also provides a message sending device, and message receiving method and device. Due to the adoption of the technical scheme, the cost of products can be reduced under the condition that the MPLS-TPOAM function is not influenced.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method and device for sending and receiving messages. Background technique [0002] Driven by the trend of IP (Internet Protocol)ization of telecommunication services, the services carried by the transport network have changed from time division multiplexing (TDM, Time Division Multiplexing) to IP. Driven by this demand, it is represented by Multi-Protocol Label Switching-Transport Profile (MPLS-TP, Multi-Protocol Label Switching-Transport Profile) and Provider Backbone Bridge-Traffic Engineering (PBB-TE, Provider Backbone Bridge-Traffic Engineering). The Packet Transport Network (PTN, Packet Transport Network) technology is the product of the combination of IP / MPLS or Ethernet bearer technology and transport network technology. Including voice, data and video services. [0003] Among them, MPLS-TP introduces the operation management and maintenance (OAM...
