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 present application provides a method for issuing a Flow spec entry, a network device, a controller, and an autonomous system. The method includes: if the received message is a Border Gateway Protocol flow rule BGP Flow spec protocol message, according to the The community attribute field included in the BGP Flow spec protocol message determines whether the local community attribute field identical to the community attribute field is stored locally; if stored, the Flow spec entry of the BGP Flow spec protocol message is added to the In the Flow spec table corresponding to the local community attribute field; according to the preset correspondence between the local community attribute field and the local interface group, the Flow spec table is sent to the local interface group corresponding to the local community attribute field, to achieve Different Flow spec entries are issued for different interfaces, making the Flow spec function more flexible to use and saving hardware resources at the same time.

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 ...
