Embodiment Construction

[0047] The technical solution of the present application will be described in detail below through specific examples.

[0048] figure 1 It is a schematic structural diagram of a communication network according to an embodiment of this application. The communication network may be, for example, a campus network. The communication network includes a plurality of network devices, the plurality of network devices include a control device and a plurality of forwarding devices, and the plurality of forwarding devices include a first network device, a second network device, a third network device and a fourth network device equipment. The multiple forwarding devices may be switches or routers, and the control device may be switches or routers. In a possible implementation, the control device may be a route reflector (route reflector, RR). exist figure 1In the shown scenario, the multiple forwarding devices may be edge network devices, such as edge switches or edge routers; the n...

Abstract

A control traffic forwarding method, device and system. The method comprises: a control device receiving a first message sent by a first network device, the first message comprising a first service message; the destination of the first message is the control device, the destination of the first service message is the first user equipment, and the first user equipment is connected to the network through the second network device. Then, the control equipment determines a first forwarding strategy according to the first message and the first routing table entry, and the first forwarding strategy is used for guiding forwarding of a first data stream to which the first service message belongs; and the control device sends the first forwarding strategy to the first network device. Therefore, the control device intervenes and controls the forwarding path of the data stream to which the message belongs according to the message sent by the network device.

Description

[0001] This application claims the priority of the Chinese patent application submitted to the State Intellectual Property Office on October 21, 2020, the application number is CN202011133176.6, and the invention title is "a control method, device and system for traffic forwarding path", all of which The contents are incorporated by reference in this application. technical field [0002] The present application relates to the technical field of communications, and in particular to a method, device and system for controlling flow forwarding. Background technique [0003] The underlying (underlay) network is a distributed network without a central control node. Each device in the underlay network learns the reachability information of the network through protocol transfer, and each device decides how to forward it. It directly leads to the lack of an overall concept and the inability to regulate traffic from the perspective of the entire network. [0004] The overlay network ...
