Embodiment 1

[0057] Embodiment 1 of the present invention takes MPLS (Multi-Protocol Label Switching, Multi-Protocol Label Switching) packet forwarding in network nodes to perform tunnel speed limit processing as an example, and illustrates that grouping services are grouped according to different priorities of sub-services on network nodes. A method for implementing differentiated services. In this embodiment, the MPLS packets accessed by the device port have the same tunnel label, and the tunnel label is configured with rate limiting parameters CIR (Committed Information Rate, Committed Information Rate) and CBS (Committed Burst Size) based on a single leaky bucket for the corresponding tunnel. , committed burst length). In this embodiment, the sharing of the total bandwidth of different priority sub-services in the tunnel is realized through rate limiting processing, and at the same time, priority forwarding of high-priority sub-services is ensured.

Abstract

The invention discloses a method and a device for achieving differentiated service of packet service. The method comprises the following steps: configuring traffic parameters of a service, allocating corresponding priority or weight to each sub-service according to service identifies of the sub-services, and allocating corresponding sub-token bucket to each sub-service, wherein, the bucket depth of the sub-token bucket is equal to the bucket depth of the service; determining the available tokens of the service according to the traffic parameters of the service at a preset timing time interval; distributing the available tokens to the corresponding sub-token bucket of each sub-service according to the relationship of the priority or the weight of the sub-services; and transmitting messages of each sub-service to corresponding sub-token barrel according to the service identity of each sub-service to carry out dyeing treatment. The device comprises a priority or weight distribution module, a token distribution module, and a dyeing treatment module. The method and the device can realize bandwidth share and bandwidth control for forwarding messages based on priority or weight of the sub-services.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for realizing differentiated services of packet services. Background technique [0002] When a traditional packet forwarding device implements differentiated service processing, it needs to be implemented based on queue scheduling. Queue scheduling is to assign each sub-service of a service flow to different queues, and output shaping is performed between the queues to realize differentiated services among various output sub-service flows. For complex business flows and a large number of business flow processing, the number of queues and the number of scheduling levels are increased, so the complexity of scheduling is also increased, and the cost of implementation is also high. [0003] In the data forwarding process in the Packet Transport Network (PTN), when realizing the rate limit of tunnel forwarding services, the rate limit based on priority control of differe...
