Abstract

The present invention provides a ring network protection switching device and method, wherein the device includes: a protection logic processing module, which is used to obtain the transmission information of the node where the protection logic processing module is located, and detects that the node is located in the working tunnel segment In the case of a failure, determine whether switching is required, wherein the transmission information includes: the information used to transmit service flows before and after the protection switching of the ring network where the node is located; the protection switching execution module is used to judge in the protection logic processing module Switching is required and after the transmission information of the node sent by the protection logic processing module is received, the node is switched according to the transmission information. The invention solves the problem of long time required for ring network protection switching in the related art, thereby effectively shortening the time required for ring network protection switching and improving the efficiency of ring network protection switching.

Description

technical field [0001] The present invention relates to the communication field, in particular to a ring network protection switching device and method. Background technique [0002] The explosive growth of IP services and the emergence of a large number of data services have made the Synchronous Digital Hierarchy (SDH) technology with Time Division Multiplex (TDM) circuit switching as the core unable to adapt to business packet transmission. In order to meet the needs of the needs, the Packet Transfer Network (PTN) technology with IP packet switching as the core came into being. It successfully realized the unified bearing of all services and the integration of the network, forming a flexible, efficient and low-cost packet transfer network. Delivery platform. Due to the importance of PTN carrying services in the short term and the comprehensiveness of long-term carrying services, the reliability of the PTN network is extremely important. Therefore, the research on the prot...
