Embodiment Construction

[0034] The core of the present invention is to identify the best-effort delivery service in the MPLS ring network, and use a fair algorithm to allocate the bandwidth occupied by the best-effort delivery service, so as to ensure that each best-effort delivery service can occupy the remaining bandwidth fairly.

[0035] The method of the present invention is as image 3 and Figure 4 As shown, it mainly includes the following steps:

[0036] Step 41: On the MPLS ring network node, determine that it is a best-effort delivery service according to the information carried in the received message, that is, when the ring network node is blocked, determine the corresponding service from the message received by the ring network node Best-effort delivery service packets, so as to facilitate corresponding processing based on traffic fair delivery;

[0037] Specifically, it can be identified according to the service transmission value of the Exp (experimental domain) field in the MPLS pac...

Abstract

The invention relates to a method to transmit flow fair in MPLS ring network, which comprises: first, determining whether the said message requires do its best to transmit according to the carried information in MPLS message; then, calculating the usable fair band width with fair algorithm; finally, sending the message in MPLS ring network based on said fair broadband. Thereby, this invention ensures the transmitted business to take up broadband resource fairly and reasonably in MPLS ring network.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for realizing fair traffic transmission in an MPLS ring network. Background technique [0002] MSTP (Multi-Service Transport Node) based on SDH (Synchronous Digital Hierarchy) system can well support TDM (Time Division Multiplexing) voice service and DDN (Digital Data Network) private line service, but it does not support IP packet service very well. The uncertainty and unpredictability of the IP traffic itself makes the use of traditional SDH equipment to provide IP packet transmission services lack of dynamic bandwidth adjustment capabilities, low resource utilization, poor network scalability, complex equipment implementation, weak topology automatic management capabilities, etc. shortcoming. [0003] Ethernet technology can well support IP packet services, has the characteristics of simplification, easy expansion, and low price, and has been widely use...
