Abstract

The invention provides a method for realizing an Ethernet protection switching. The method comprises: in two data units dual-homed connected in the Ethernet, when a data unit which is transmitting a service learns local link anomalies, inserting an alarm in a time slot of a corresponding system port, and a cross board choosing the system port's time slot of the data unit without the alarm to transmit the service according to a sub-network connection protection. The invention also provides a system for realizing the Ethernet protection switching. The method and the system can effectively solve a problem that in a dual-homed connection, the service cannot be continuously transmitted as normal when a channel is broke down.

Description

technical field [0001] The present invention relates to the technical field of network communication, and in particular to a method and system for realizing protection switching of Ethernet services. Background technique [0002] With the development of the Internet and the rapid growth of data services, Ethernet technology has been widely and importantly applied; and due to the inheritance and development of communication technology applications, Ethernet is also moving towards Multi-Service Transport Platform (MSTP for short) direction development. In the actual application of Ethernet, some services have higher and higher requirements on the reliability and real-time performance of the network. Therefore, a method for supporting high reliability and real-time Ethernet Protection Switching (Ethernet Protection Switching, EPS for short) is needed in the network. [0003] Such as figure 1 As shown in , it describes the schematic diagram of Ethernet dual-homing connection....
