Embodiment Construction

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. the embodiment. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0042] At present, after the network device receives the Flow spec, it can only take effect on all boards and interfaces globally. In this way, Flow spec entries will also be issued to some interfaces that do not have traffic matching Flow spec entries. , resulting in a waste of hardware resources; on the other hand, flexible control of packets cannot be achieved. For example, the pac...

Abstract

The invention provides a Flow spec table entry issuing method, network equipment, a controller and an autonomous system; the method comprises the following steps: if the received message is a border gateway protocol flow rule BGP Flow spec protocol message, whether a local group attribute field the same as a group attribute field is locally stored according to the group attribute field included inthe BGP Flow spec protocol message; if the local group attribute field is stored, the Flow spec table entry of the BGP Flow spec protocol message is added to a Flow spec table corresponding to the local group attribute field; according to a preset correspondence between the local group attribute field and a local interface group, the Flow spec table is issued to the local interface group corresponding to the local group attribute field, so that different Flow spec entries can be issued for different interfaces, and the Flow spec function is more flexible to use; meanwhile, the technical effect of hardware resources is also saved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method for issuing Flow spec entries, network equipment, a controller and an autonomous system. Background technique [0002] Border Gateway Protocol (Border Gateway Protocol, BGP) is a dynamic routing protocol used between self-made systems, and BGP flow rules (Flow Specification, Flow spec) indicate that traffic policies are passed to BGP Flow Specification by passing BGP FlowSpecification routes On the peer device, the BGPFlow spec route is used to define the characteristics of the flow and the behavior of the flow (such as: flow rate limit, redirect actions (redirectActions), modify the DSCP value of the message, filter the flow, etc.), so as to realize the Enable BGP Flow spec on the network, and deliver BGP Flow spec routes to devices in the network, so as to prevent DDOS attacks in the network and guide network traffic forwarding. [0003] Existing ...
