Problems solved by technology

At this time, the standby controller is upgraded to the master controller, and the standby controller cannot obtain the protocol packet, so the standby controller cannot process the protocol packet, which may cause service interruption.

Embodiment Construction

[0104] The embodiment of the present invention provides a protocol message processing method, the protocol message processing method is mainly applied to a system composed of a master controller, a standby controller, a forwarding node, and a peer node, so that if the master If the controller fails, the backup controller can seamlessly take over the master controller, so as to effectively ensure that the protocol and forwarding traffic are not interrupted. The following combination figure 2 A detailed description of a protocol message processing method provided by the embodiment of the present invention is shown in the following figure:

[0105] 201. The forwarding node receives the first protocol packet sent by the peer node to the main controller;

[0106] A TCP connection between the main controller and the Peer node is established, so that the forwarding node can forward the first protocol message generated by the Peer node to the main controller.

[0107] The forwarding...

Abstract

The embodiment of the invention discloses a method for processing protocol messages, a method for processing faults of controllers and a related device. The method for processing the protocol messages comprises the steps that the first protocol message sent to the master controller by a Peer node is received by a forwarding node and then stored in a database by the forwarding node so that the first protocol message can be obtained by the standby controller; the first protocol message is sent to the master controller by the forwarding node, so that the first protocol message is processed by the master controller. Back-up is conducted on the first protocol message by the forwarding node so that if the master controller breaks down, the first protocol message can be obtained from the database by the standby controller, the phenomenon that if the master controller breaks down, the first protocol message sent by the Peer node is lost is avoided, and the standby controller replaces the master controller for processing the first protocol message.

Description

technical field [0001] The invention relates to a communication system, in particular to a protocol message processing method, a controller fault processing method and related equipment. Background technique [0002] Software Defined Network (Software Defined Network, SDN) is a new network innovation architecture proposed by the clean slate research group of Stanford University in the United States. Its core technology, Open Flow, realizes Flexible control of network traffic provides a good platform for core network and application innovation. Its advantage is that the SDN controller integrates multiple network services on the basis of centralized control of the network. Users only need to invest in one controller to complete all network control functions. And when the service is provisioned based on the SDN network, the user's policy is centralized in the controller, and the controller identifies the host access, and then dynamically delivers the service to the network ac...
