Embodiment Construction

[0027] Please refer to figure 1 It is a schematic diagram of the organization of non-iterative routing and forwarding entries. When LR (LineRate, rate limit) is configured under the TE tunnel, the TE will apply for the queue number FLOWID resource, and implement the hardware rate limit of the tunnel based on the queue, that is, the forwarding traffic rate entering the queue will be Limited by the size of the FLOWID resource.

[0028] In the specific implementation process, the FLOWID resource will be delivered to the OUTLIF table (outgoing interface table) of the tunnel of the TE, and the OUTLIF table records various attributes based on the configuration of the outgoing port. The FIB (Forwarding Information Base, Forwarding Information Base) table of the forwarding prefix of the traffic is directly associated with the OUTLIF table of the TE, and the value of the FLOWID is obtained therefrom to perform TM (Traffic Management, traffic management) rate limiting.

Abstract

The present disclosure provides a method and device for tunnel rate limiting. By pre-establishing the corresponding relationship of LSP tunnel nodes for TE tunnel iteration, after obtaining the queue number resource of any TE tunnel, the outgoing interface entry corresponding to the specified LSP tunnel node is obtained. , and then deliver the queue number resource to the outbound interface entry corresponding to the specified LSP tunnel node, so that the specified LSP tunnel node can limit the speed according to the queue number resource in the outbound interface entry, so as to realize the networking in route iteration. Under the circumstance, the bandwidth resources under the TE tunnel are effectively used to ensure the effectiveness of the TM rate limiting function of traffic.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a method and device for speed limiting in a tunnel. Background technique [0002] Currently, for TE (Traffic Engineering, traffic engineering) tunnels, resources can be dynamically allocated when the environment changes, and services are not interrupted. Since the user cannot determine how much bandwidth the service provider needs to provide initially when using the bandwidth, but from the user's point of view, they are more willing to pay for the bandwidth that has been used, so the service provider can try to avoid providing more bandwidth than the user needs. Dynamic allocation method to provide bandwidth to users. However, when the service provider dynamically allocates bandwidth resources to users, it will not provide unlimited bandwidth guarantees for users due to the continuous growth of user traffic. Therefore, users need to dynamically adjust band...
