Problems solved by technology

[0003] However, in many complex business scenarios, factors affecting network services are not limited to continuous packet loss or bit errors, and there are many other factors that make it impossible to switch working channels in time, such as: transmission delay
However, it is difficult to accurately determine whether there is a large delay in data transmission according to the reception status of the existing CCM. Therefore, when there are many factors affecting network services, the current channel protection switching mechanism is difficult to trigger the switching of the working channel in time. Channels with low transmission capacity undertake network services, reducing the quality of network services in complex service scenarios

Embodiment Construction

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0044] This application is applicable to a transmission network, which includes at least a source-end service provider edge PE and a sink-end service provider edge PE. Referred to as the sink PE, the source PE is connected to the sink PE through at least two channels including the first channel and the second channel; the current working channel of the source PE and the sink PE is the first channel , the working channel is the channel used by the source PE and the sink PE to transmi...

Abstract

The invention discloses a method and a device for managing a data transmission channel, relates to the technical field of communication, and can improve the quality of network services in a complex service scene. The method comprises the following steps: acquiring the time delay of data transmitted on a first channel, the continuity parameter of the first channel, the time delay of data transmitted on a second channel and the continuity parameter of the second channel; detecting whether a fault event occurs on the first channel or not; and if the fault event occurs on the first channel, switching a working channel of a source end service provider edge PE and a working channel of a destination end service provider edge PE to the second channel.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for managing a data transmission channel. Background technique [0002] At present, with the development of communication technology, many data transmission networks will adopt a transmission subset based on Multi Protocol Label Switching (English: Multi Protocol Label Switching Transport Profile, MPLS-TP for short) technology. One of the main functions of the MPLS-TP technology is to keep the data transmission channels used to undertake network services unimpeded. The channel protection switching mechanism in MPLS-TP technology is roughly as follows: the source-end service provider edge PE (English: Provider Edge, PE for short) router and the sink-end PE router (usually the source-end PE router is referred to as the source-end PE for short, and the sink-end PE The router is referred to as the sink PE) in the process of data exchange, the...
