Abstract

The embodiment of the present invention discloses a cross-device linear multiplex section protection method, a gateway, and a controller. The method includes: the controller receives a first negotiation message sent by the first gateway, and the first negotiation message is when the sent when the first gateway detects a link failure with the second gateway; the controller sends a second negotiation message to the first gateway and the second gateway, so that the second gateway Decrease to the standby state according to the second negotiation message, wherein the second negotiation message is used to indicate to bridge the service data on the working link to the protection link for transmission, and the working link is the A link between the second gateway and the controller, the protection link is a link between the first gateway and the controller. The present invention is applicable to the scenario where the SDH network dual-homing accesses the public network.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a cross-device linear multiplexing section protection method, a gateway and a controller. Background technique [0002] APS (AutomaticProtectionSwitching, automatic protection switching) is an important feature of SDH (SynchronousDigitalHierarchy, synchronous digital series) network. APS refers to the use of a protection channel to provide protection for one or more working channels. When a fault occurs on the working channel, the services originally transmitted on the working channel can be automatically switched to the protection channel, thereby ensuring that user data is not lost and improving network reliability. The APS protocol is transmitted through K1 bytes and K2 bytes in MSOH (MultiplexSectionOverhead, multiplex section protection). The K1 byte is used to transmit the switching request signal, and the K2 byte is used to transmit the bridge status signal. The p...
