Problems solved by technology

[0008] To sum up, in the prior art, partial QoS guarantees can be realized inside some access devices, and some devices can also provide certain differentiated services. However, since these devices do not have the ability to identify service types, they cannot target different Business bandwidth control and differential service provision
Moreover, the QoS policies of these traditional devices cannot change dynamically with the resources of the network, let alone implement traffic monitoring.

Embodiment Construction

[0037] In order to provide differentiated services for each service connection, the present invention proposes an access network structure.

[0038] see Figure 5 As shown, the access network of the present invention includes a service control function entity (SCF), an access-side bearer network resource management entity (ACM), a BRAS and an access bearer network. The access bearer network includes CPE and DSLAM.

[0039] Among them, SCF is composed of various service control platforms that process user service applications. It determines the current service connection parameters according to user service requests: QoS parameters, IP quintuples, namely source IP address, destination IP address, protocol number , source port number, and destination port number, and then apply to the ACM for the bearer path of the service flow. Moreover, logically, there may be multiple SCFs, and each SCF is aimed at a service type, that is, each SCF processes a service request. Moreover, the ...

Abstract

This invention discloses a kind of method for ensuring end -to -end service quality. After receiving the service connection request sent by UE, SCF ensures connection parameters of this time service and sent resource request containing the connection parameters of this time service to ACM. ACM ensures QoS strategy and sends the QoS setting message containing the QoS strategy to BRAS; BRAS sends QoS setting message containing the said QoS strategy to each downstream switch-in node device. According to the said QoS strategy, each switch-in node sets up QoS and service connection; according to the assigned QoS strategy, service flow carried out retransmitting in switch-in network. This invention also discloses a kind of switch-in network that ensures the end to end service quality.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for ensuring end-to-end business service quality and an access network. Background technique [0002] Such as figure 1 As shown, the access side of the current network usually includes customer premises equipment (CPE), digital subscriber line access server (DSLAM), broadband remote access server (BRAS) and other aggregation equipment, such as routers, switches (LAN SWITCH) Wait. [0003] The traditional CPE is a simple xDSL MODEM with bridging and routing functions. It does not have bandwidth control and differential service functions, nor can it realize traffic supervision, but it supports multi-PVC / VLAN configuration and multi-port address learning function. With more and more services on the user side, in order to support data services, packet voice services and packet video services at the same time, the new enhanced CPE functions are becoming more and more...
