Problems solved by technology

[0004] In view of this, the purpose of the embodiments of the present invention is to provide a network flow control method, VTEP equipment and storage media to solve the configuration troubles in the flow control mode when the network is congested in the prior art, which is not conducive to centralized management of flow, and will Destroy the user's original message and original quality of service information, and when the network is congested, a large amount of traffic will still be sent to the congested device, which will continue to put pressure on the congested device, resulting in the inability to recover business traffic quickly technical issues

Embodiment 1

[0031] figure 2 It is a schematic diagram of the implementation flow of the network traffic control method provided by the embodiment of the present invention, and the execution subject of the method is figure 1 The first VTEP device in the see figure 2 As shown, the network flow control method provided in this embodiment includes the following steps:

[0032] In step S201, the first VTEP device configures a traffic type and a service priority for the service traffic according to the service type of the service traffic being accessed.

[0033] In this embodiment, the manager of the EVPN VXLAN network pre-configures the service type of the service traffic and the association relationship between the traffic type and the service priority. After receiving the service flow sent by the user side, the VTEP device identifies the service type of the service flow, and then queries the association relationship according to the identified service type to obtain the flow type and ser...

Embodiment 2

[0041] Figure 4 It is a schematic diagram of the implementation flow of the network traffic control method provided by another embodiment of the present invention, and the execution subject of the method is figure 1 The first VTEP device in the see Figure 4 As shown, the network flow control method provided in this embodiment includes the following steps:

[0042] In step S401, the first VTEP device configures a traffic type and a service priority for the service traffic according to the service type of the service traffic being accessed.

[0043] It should be noted that since the implementation of step S401 is exactly the same as the implementation of step S101 in the previous embodiment, it will not be repeated here.

[0044] Step S402, the first VTEP device judges whether the flow control message sent by the second VTEP device is received, the flow control message includes the congestion flag bit and the expected bandwidth of the second VTEP device, if the first VTEP d...

Abstract

The embodiment of the invention discloses a network flow control method, VTEP equipment and a storage medium, and relates to the technical field of communication. The method comprises the steps that first VTEP equipment configures a flow type and a service priority for service flow according to the service type of the accessed service flow; the first VTEP equipment encapsulates the service flow into an extensible virtual local area network (VXLAN) message, and encapsulates the flow type and the service priority of the service flow into the VXLAN message; and the first VTEP device sends the VXLAN message to the second VTEP device, so that the second VTEP device performs flow control on the service flow according to the flow type and the service priority of the service flow carried in the VXLAN message when congestion occurs. According to the embodiment of the invention, centralized management can be carried out on the access flow, and the network congestion processing efficiency of theVTEP equipment is improved.

Description

technical field [0001] The present invention relates to the technical field of data communication, in particular to a network flow control method, an extensible virtual local area network tunnel termination point (Virtual Tunnel End Point, VTEP) device and a storage medium. Background technique [0002] With the development of network technology, the Internet data center network continues to expand, and the Ethernet Virtual Private Network (EVNP) technology using the scalable Virtual Local Area Network (Virtual eXtensible LAN, VXLAN) technology is getting more and more applications. EVPN is a Layer 2 virtual private network technology. The control plane uses the multi-protocol border gateway protocol to advertise EVPN routing information, and the data plane uses VXLAN encapsulation to forward packets. When tenants' physical sites are scattered in different locations, EVPN can provide Layer 2 interconnection for the same subnet of the same tenant based on the existing service...
