[0039] In this embodiment, the microwave node device may include: a fault detection module, a main control module, an agent module and a driving task module. The main control module realizes interaction with the local management terminal (Local Management Part referred to as LMP) and network element management system (Element Management System, referred to as EMS). In this embodiment, LMP and EMS belong to the management interface, and local or remote users use this Two modules to complete device management functions; the driver task module has a higher priority and is used to complete the quick configuration of zero-lag time V4-level routing; the proxy module completes non-zero-lag time V4-level routing configuration, and completes return time and lag time response At the same time, it is necessary to complete the chip setting of VC12-level SNCP routing and the execution of commands (clearing, protection blocking, forced switching, manual switching) operations. Among them, th...

Abstract

The invention discloses a route switching method in subnet connection protection and a microwave nodal point device. The method includes that the microwave nodal point device receives local request orders, obtains interruption port information and determines to be switched to a matched SNCP route according to configuration state and the interruption port information. By means of the technical scheme, the method resolves the problem in the relative art that subnet connection protection in VC4 grade and VC12 grade is poor in reliability and time and further improves reliability of the subnet connection protection.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a route switching method and microwave node equipment in SubNetwork Connection Protection (SNCP for short). Background technique [0002] Microwave communication technology has been in existence for more than half a century. It is a wireless communication method for information transmission through ground line-of-sight in the microwave frequency band. In order to improve service availability and increase network flexibility, microwave equipment supports the transmission of Synchronous Digital Hierarchy (referred to as SDH) services, and implements add / drop multiplexer (Add / Drop Multiplexer, referred to as ADM) / terminal multiplexer Termination Multiplexer (TM for short) and Synchronous Transfer Module (STM for short) transparent transmission function. [0003] SDH protection is divided into subnet connection protection and path protection. Path protection includes multiplex sec...
