Abstract

The invention discloses a method, equipment and a system for improving type B protection switching performance. The method comprises: when an OLT has no fault, backing up the related information of a main PON port into a standby PON port and informing all ONUs of the fact that the OLT is in a type B protection state; when a fault is detected in the OLT, switching the main PON port to the standby PON port and sending a deregistration request to all ONU of the OLT; and after the OLT receiving re-registration requests of the ONUs, giving discovery windows in a whole period to all ONUs in a first authentication period and giving the discovery windows in part of the period to unregistered ONU in a subsequent authentication period till all ONUs finish re-registration. The equipment comprises an information backup unit, a deregistration request sending unit and a discovery window distribution unit. The method of the invention solves the problems of long switching time and unsatisfactory reliability of the prior art.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, device and system for improving Type B protection switching performance. Background technique [0002] As a broadband access technology, EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network) has begun to enter a stage of large-scale deployment and has begun to enter various fields. Since commercial users, especially those with high reliability requirements, such as banks, electric power companies, and large enterprises, have relatively high reliability requirements, three mainstream protection technologies of Type A, B, and C have emerged. Among them, Type B protection has become the most popular protection method for operators due to its relatively low cost and high reliability, such as figure 1 Shown is a schematic diagram of Type B protection in the prior art. [0003] A typical Type B protection switching process includes: OLT (Optical L...
