Embodiment Construction

[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0024] see figure 2 , which shows the working model of Linktrace using MPLS-TP OAM following the present invention. As can be seen from the figure, in the present invention, the exchange chip no longer forwards the received Linktrace response message to the software of the CPU for processing, but forwards it to the MPLS-TP OAM engine implemented by the FPGA for processing.

[0025] In the present invention, the MPLS-TP OAM engine function is realized based on the FPGA, and the processing of the linktrace corresponding message is realized thereby, effectively avoiding the problem that the CPU load increases when processing a large number of Linktrace response messages.

[0026] see image 3 , when the present invention processes the Linktrace ...

Abstract

The invention discloses a method for realizing Linktrace of MPLS-TP OAM based on FPGA. The method comprises the following steps: (1) the exchange chip receives the Linktrace response message and forwards it to the FPGA in the system; (2) MPLS-TP OAM implemented by the FPGA The TP OAM engine processes the Linktrace response message, and stores the processed result in the memory dedicated to the OAM engine for storage; (3) The CPU directly reads and displays it from the memory dedicated to the OAM engine. Utilizing the present invention will not cause impact on the CPU when the system receives a large number of Linktrace response messages.

Description

technical field [0001] The invention belongs to the technical field of packet transport network (PTN, PacketTransport Network) in data communication technology and data transmission technology, and specifically relates to a method for realizing Linktrace of MPLS-TP OAM based on FPGA. Background technique [0002] A Packet Transport Network (abbreviated as PTN hereinafter) is a telecommunications transmission network, which is a converged technology. In order to realize the maintainability and manageability of the PTN network, the PTN technology incorporates some characteristics and functions of OAM similar to SDH (Synchronous Digital Hierarchy, Synchronous Digital Hierarchy). In PTN technology, this SDH-like OAM (Operation Administration and Maintenance, Operation-Operation, Management-Administration, Maintenance-Maintenance) function is collectively referred to as MPLS-TP OAM, which is a series of operations applied in the MPLS-TP network environment , management, maintena...
