Problems solved by technology

[0003] The current problem is that when the above-mentioned tunnel forwarding network encapsulates and forwards packets, it forwards all types of packets equally. When it is too large, control packets and protocol packets may be discarded, so that the control packets and protocol packets cannot be transmitted correctly, resulting in the inability to ensure timely transmission of session information between the VCF controller and the server, affecting the server's Business execution, for example, the server cannot receive the latest flow table issued by the controller in time, so traffic forwarding cannot be performed according to the latest flow table

Embodiment Construction

[0024] SDN is a network that separates the control plane and the data plane. In SDN, the SDN controller is the control center, which is responsible for generating the flow table and sending it to the forwarding device in the SDN. The forwarding device processes the message according to the received flow table sent by the controller. deal with. Such as figure 1 As shown, the figure 1 The network shown is the network architecture of SDN, and the network includes a VCF controller 11 (this embodiment takes VCF as an example, and other controllers can also be used in specific implementations), a forwarding network 12 and a plurality of servers 13 (including server 1 , server 2 and server 3, etc.); wherein, the forwarding network 12 is a tunnel forwarding network such as a VXLAN network, and the starting edge forwarding device of the network performs VXLAN tunnel encapsulation on the message after receiving the message sent by the source device, and then Forwarding is performed on...

Abstract

The invention provides a message control method and equipment. The message control method includes the steps that edge forwarding equipment in a channel forwarding network is obtained and is connected with a controller or a server; the controller sends a message control strategy to the edge forwarding equipment so that the edge forwarding equipment can set the priority of a message between the controller and the server as the highest priority according to the message control strategy. The message control method and equipment can guarantee that the message is sent preferentially according to the highest priority in the forwarding network, and the situation that the message between the controller and the server is abandoned is avoided as much as possible.

Description

technical field [0001] The invention relates to network technology, in particular to a message control method and equipment. Background technique [0002] In the software-defined network (Software Defined Network, referred to as: SDN) network architecture, the control plane and forwarding plane of network equipment are separated, and the network traffic is controlled centrally through the SDN controller. The Virtual Converged Framework (Virtual Converged Framework, referred to as : VCF) controller is one of the controllers. In one application, the middle of the message between the SDN controller and the service server can be forwarded through the tunnel forwarding network. For example, the tunnel network is a VXLAN network, and the message between the SDN controller and the service server reaches the edge device of VXLAN (VTEP), the packets between the SDN controller and the service server are tunnel-encapsulated according to the format specified by VXLAN, forwarded to the ...
