Method and device for managing data transmission channels

Abstract

The invention discloses a method and device for managing data transmission channels, and relates to the technical field of communications. Through the adoption of the method and device, the quality of network services in complicated business scenes can be improved. The method comprises the following steps: obtaining the time delay of the data transmitted on the first channel and the continuous parameters of the first channel, and the time delay of the data transmitted on the second channel and the continuous parameters of the second channel; detecting whether a failure event occurs on the first channel or not; if yes, switching the working channel for a source service provider edge PE and a sink service provider edge PE to the second channel.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for managing data transmission channels. 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. [0003] 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, there are...

Problems solved by technology

[0004] 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
