Common telecommunication grouping data network system and congestion control method thereof

Abstract

The invention provides a PTDN and the congestion control process, wherein the process comprises the following steps that arranging the parameter of a VPN channel for the outlet interface of each intermediate node of the PTDN in order to divide the chain channel of the PTDN into several VPN channels which respectively comprise a VPN number, business flow sorts and an outlet interface ID, wherein the VPN number is relative to the business sort, the business flow sort means the service which is provided for the business sort, and the intermediate nodes of the same VPN comprise a VPN channel, conducting one-time congestion examination when the intermediate nodes of the VPN channel receive one message of the business flow of the business flow sort, and searching whether the outlet interface ofthe outlet interface ID has the congestion records of the business flow if the congestion is searched, not sending congestion warning indicating information if has the congestion records, or simultaneously sending the congesting warning indicating information to a data source end if has the congestion records. The invention increases the network congestion control for the PTDN.

Description

technical field [0001] The present invention relates to the communication field, in particular to a public telecommunication packet data network system and a congestion control method thereof. Background technique [0002] PTDN (Public Telecom Data Network, Public Telecom Packet Data Network) can be used to carry existing telecommunication services, and can guarantee that the telecommunication services carried by it can provide the same quality of service (QoS, Quality of Service) as traditional telecommunication services. For example, PTDN can not only carry Internet (Internet) services, provide the same capabilities as the existing Internet, support existing Internet services, but also be used to carry other services that may arise in the future. [0003] PTDN is a trusted network. The data plane, control plane and management plane of the business network built on it can ensure the security of the business network without using security encryption technology and establishi...

AI Technical Summary

Problems solved by technology

[0005] In the process of realizing the present invention, the inventor found that the telecommunication services carried by the existing PTDN may suddenly increase the amount of data, resulting in network congestion, and network congestion often leads to packet loss, excessive delay and other problems that degrade network performance , while the existing PTDN lacks proper control over network congestion
