State control method, device and message transmission method

Abstract

The invention provides a state control method, a state control device, and a message transmission method, and relates to the communication technology field. The state control method is used for VXLANTunnel End Point VTEP. The state control method comprises steps that a first protocol message is configured on an interface corresponding to the VTEP, and the first protocol message comprises block priority corresponding to an access circuit AC bonded with the interface and a network identification corresponding to VSI of the AC; the first protocol message is transmitted from the AC, and a secondprotocol message transmitted by other VTEP; whether the network identification in the second protocol message is matched with the network identification of the first protocol message is determined, when yes, and the blocking priority in the second protocol message is higher than the blocking priority in the first protocol message, and the working state of the AC is set as a blocking state. By adopting the technical scheme provided by the invention, the convenient control over the AC working state corresponding to the VTEP is realized, and therefore reliability of data message transmission is guaranteed.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a state control method, an apparatus, and a message transmission method. Background technique [0002] In the scenario where the multi-homed user edge device accesses the operator network, loops are easily formed between the virtual tunnel endpoints (VXLAN Tunnel End Point, VTEP) to which the user edge device is multi-homed, which affects the reliable transmission of data packets. , how to easily improve the loop problem needs to be studied. Among them, VXLAN (Virtual Extensible LAN) is a network virtualization technology. VXLAN can provide Layer 2 interconnection for scattered physical sites based on the existing service provider or enterprise IP (Internet Protocol, the protocol for interconnection between networks). Different tenants provide business isolation. SUMMARY OF THE INVENTION [0003] In view of this, the purpose of the present disclosure is...
