Embodiment Construction

[0052] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0053] The method for multiplexing section protection in the packet transmission network of the present invention is applied to the multiplexing section protection of the main service in the packet transmission network. The packet transport network includes a main channel and a backup channel, and the two ends of the main channel are main ports of the main board for running main services. The two ends of the standby channel are the standby ports of the standby board, which generally do not carry services and are used for multiplex section protection when the main service link fails. Multiplex section protection includes linear multiplex section protection and ring network multiplex section protection. The multiplex section protection of the present invention is mainly used for one-to-one (1:1) bidirectional protection...

Abstract

The present invention relates to multiplex section protection method and system. The method includes the following steps: a main single board detects main port alarm information of a main channel at real-time, and sends the main port alarm information to a main control board; a standby single board detects standby port alarm information and a standby port K1K2 byte of a standby channel at real-time, and sends the standby port alarm information and the standby port K1K2 byte to the main control board; according to the main port alarm information, the standby port alarm information, the standby port K1K2 byte and preset external control order, the main control board determines whether a main service works in the main channel or the standby channel. Once the multiplex section protection main control board and system of the present invention detect that the main service needs to switch via the real-time detection of the main port alarm information, the standby port alarm information and the standby port K1K2 byte, the main control board performs the main service switch in time according to the main port alarm information, the standby port alarm information, the standby port K1K2 byte and preset external control order; which further improves the safety and reliability of the data transmission in the packet transport network.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to a method and system for multiplexing section protection in a packet transmission network. Background technique [0002] The MSTP (Multi-Service Transfer Platform) technology based on SDH (Synchronous Digital Hierarchy) provides the transport function of carrier-class packet services, reflecting the evolution trend of optical transport network to support packet transport. However, MSTP is still based on TDM (Testing Data Management / Technical Data Management, test data management / technical data management) as the core, and it is difficult to meet the application requirements mainly based on packet services. Therefore, the industry has proposed a transport network mainly suitable for packet services——PTN (Packet Transport Network, packet transport network). The PTN can efficiently transmit packet services, and provides carrier-class OAM (Operation Administration and Maintenance...
