一种分配调度资源的方法、系统及路由设备A method, system and routing device for allocating and scheduling resources

技术领域technical field

本发明涉及通信领域，特别涉及一种分配调度资源的方法、系统及路由设备。The present invention relates to the communication field, in particular to a method, system and routing equipment for allocating and scheduling resources.

背景技术Background technique

如图1所示的组网拓扑中，用户侧PE设备120汇聚并透传用户终端131与用户终端132的业务，所有业务统一由宽带接入服务器110(BroadbandRemote Access Server，BRAS)进行用户管理及认证，由于用户规模越来越大，为减轻宽带接入服务器110的处理负担，将宽带接入服务器110的功能转移到用户侧PE设备120上实现，即采用分布式宽带接入服务器。In the networking topology shown in Figure 1, the user-side PE device 120 aggregates and transparently transmits the services of theuser terminal 131 and theuser terminal 132, and all services are uniformly managed by the Broadband Remote Access Server 110 (Broadband Remote Access Server, BRAS). Authentication, because the scale of users is getting larger and larger, in order to reduce the processing burden of thebroadband access server 110, the function of thebroadband access server 110 is transferred to thePE device 120 on the user side for implementation, that is, a distributed broadband access server is used.

基于分布式宽带接入服务器，对于IPoE(IP over Ethernet)接入方式的业务通常在用户侧PE设备120上进行用户管理及认证，但对于PPPoE(Point-to-Point Protocol over Ethernet)接入方式的业务通常仍在宽带接入服务器110上进行用户管理及认证，用户侧PE设备120只是透传PPPoE业务。Based on the distributed broadband access server, for IPoE (IP over Ethernet) access services, user management and authentication are usually performed on the user-side PE device 120, but for PPPoE (Point-to-Point Protocol over Ethernet) access services The services of thebroadband access server 110 are usually still managed and authenticated by users, and thePE equipment 120 on the user side only transparently transmits PPPoE services.

基于上述介绍，同一用户终端可能同时存在IPoE接入方式的业务和PPPoE接入方式的业务，可能部分业务在用户侧PE设备120进行用户管理及认证，部分业务则经过用户侧PE设备120透传，由宽带接入服务器110进行用户管理及认证。为保证业务的服务质量，需要做层次化服务质量(Hierarchical Quality of Service，HQoS)调度，对于非透传业务，用户侧PE设备120可感知其上下线，当用户终端131的第一个上线业务为非透传业务时，用户侧PE设备120可以为用户终端131动态分配调度资源，实现HQoS调度，但当用户终端131的第一个上线业务为透传业务时，由于用户侧PE设备120无法感知其上下线，因此用户侧PE设备120无法为用户终端131动态分配调度资源。现有技术有两种技术方案解决上述问题，分别为：Based on the above introduction, the same user terminal may have IPoE access services and PPPoE access services at the same time. Some services may be managed and authenticated by the user-side PE device 120, and some services may be transparently transmitted through the user-side PE device 120. , thebroadband access server 110 performs user management and authentication. In order to ensure the service quality of the business, Hierarchical Quality of Service (HQoS) scheduling is required. For the non-transparent transmission business, the user-side PE device 120 can perceive its on-line and off-line. When the first online service of theuser terminal 131 For non-transparent services, the user-side PE device 120 can dynamically allocate scheduling resources for theuser terminal 131 to implement HQoS scheduling. However, when the first online service of theuser terminal 131 is a transparent transmission service, the user-side PE device 120 cannot Perceiving its online and offline, the user-side PE device 120 cannot dynamically allocate scheduling resources for theuser terminal 131 . There are two technical solutions in the prior art to solve the above problems, which are respectively:

1、对于用户终端131的业务，用户侧PE设备120为非透传业务动态分配调度资源，非透传业务在用户侧PE设备120上做HQoS调度，BRAS为透传业务动态分配调度资源，透传业务在宽带接入服务器110上做HQoS调度；1. For the services of theuser terminal 131, the user-side PE device 120 dynamically allocates scheduling resources for non-transparent services, and the non-transparent services perform HQoS scheduling on the user-side PE device 120, and the BRAS dynamically allocates scheduling resources for transparent transmission services. HQoS scheduling is performed on thebroadband access server 110 for the transmission service;

2、用户侧PE设备120为用户终端131静态分配的调度资源，非透传业务和透传业务都在用户侧PE设备120上做HQoS调度。2. The user-side PE device 120 statically allocates scheduling resources for theuser terminal 131 , and HQoS scheduling is performed on the user-side PE device 120 for non-transparent services and transparent transmission services.

在实现本发明的过程中，发明人发现现有技术至少存在以下问题：In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art:

对于同一用户终端，用户侧PE设备120为用户终端131的非透传业务动态分配调度资源，BRAS为用户终端131的透传业务动态分配调度资源，由于调度资源的分离，导致同一用户终端的透传业务和非透传业务不能进行统一HQoS调度，而如果用户侧PE设备120为用户终端131静态分配调度资源，当用户终端131下线时，调度资源不能及时释放，会造成网络资源的浪费。For the same user terminal, the user-side PE device 120 dynamically allocates scheduling resources for the non-transparent transmission services of theuser terminal 131, and the BRAS dynamically allocates scheduling resources for the transparent transmission services of theuser terminal 131. Due to the separation of scheduling resources, the transparent transmission services of the same user terminal Unified HQoS scheduling cannot be performed for transmission services and non-transparent transmission services. If the user-side PE device 120 statically allocates scheduling resources for theuser terminal 131, the scheduling resources cannot be released in time when theuser terminal 131 goes offline, resulting in waste of network resources.
