Multi business IP bearing system with service quality assurance and implementing method thereof

Abstract

A multi-services IP bearer system having QoS assurance and the implementing method thereof, it includes at least : a switching function unit, which supports the resource scheduling and isolation, and support to match the specific service with the specific network resource and forward the specific service using the specific network resource; and resource control function unit, which controls and manages the resource scheduling of switching function unit, and downward-transfer the resource scheduling and the allocation rule as well as the mapping relation of the resource and the service to switching function unit. The logic networks loaded service by the bearer system are separated each other, QoS of various services is not affected from other services, and it can receive QoS feedback of the service network, schedule the resource in the IP bearer system, and improve the QoS assurance for services.

Description

technical field [0001] The present invention relates to a network system capable of carrying multiple services using Internet Protocol (Internet Protocol) (hereinafter referred to as IP) technology, in particular to a multi-service IP bearing system with Quality of Service (hereinafter referred to as QoS) guarantee and Implementation. Background technique [0002] The inherent technical and economic characteristics of IP technology have created the brilliance of the Internet (Internet) and prompted the telecom industry to try to integrate more and more telecom services, such as softswitch, Internet Protocol Television (IPTV for short), third The 3rd Generation (hereinafter referred to as 3G), the Next Generation Network (Next Generation Network, NGN for short), etc., are carried on the IP network. However, the connectionless working mode, best-effort transmission, bandwidth statistical multiplexing, and hop-by-hop congested packet discarding of IP technology make the QoS gu...

AI Technical Summary

Problems solved by technology

However, the connectionless working mode, best-effort transmission, bandwidth statistical multiplexing, and hop-by-hop congestion packet discarding of IP technology make the QoS guarantee capability of IP network inherently flawed.

Existing QoS assurance schemes, such as Integrated Services (IntServ for short) model, Differentiated Service (DiffServ for short) model, and traffic engineering, cannot be deployed on the entire network due to scalability reasons, or due to excessive management granularity Coarse cannot solve the problem of end-to-end QoS guarantee
