Problems solved by technology

However, the agreement does not stipulate how OFS dynamically connects to OFC clusters, that is, when OFS connects to OFC clusters, which OFCs need to be connected has not yet been supported by standard specifications.
Although you can manually specify which OFCs are connected to the OFS, this will greatly increase the operating cost of the product and increase the difficulty of maintenance

Embodiment Construction

[0055] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0056] Such as figure 1 As shown, a method for connecting a switch to a controller cluster includes steps:

[0057] S100. The controller receives a request message sent by the switch, and acquires a new controller to be connected to the switch in response to the request message;

[0058] The controller can include an Openflow controller, etc., and the switch can include an Openflow switch, etc. According to the message type defined by the Openflow protocol specification, the request message can use an Experimenter message with editable data segments; the format of the Experimenter message is as fo...

Abstract

The invention discloses a method and system for realizing clustering by connecting a switch with a controller, a switch, and a controller. The controller, according to a request message sent by the switch, obtains a new controller to be connected with the switch, then fills the information of the new controller in the data segment of the request message, obtains a response message, returns the response message to the switch, and according to a connection request sent by the switch, establishes connection with the new controller, such that the product operation cost and the maintenance difficulties are reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for connecting a switch to a controller cluster, a system for connecting a switch to a controller cluster, a controller and a switch. Background technique [0002] Starting from version 1.2, the Openflow protocol specification has made a normative description of OFS (OpenflowSwitch, Openflow switch) connecting multiple OFCs (OpenflowController, Openflow controller), as follows: [0003] 1. One OFS can establish Openflow connections with multiple OFCs; [0004] 2. The connection between OFS and OFC is divided into three roles: EQUAL (default role), MASTER (primary role), and SLAVE (standby role). Among them, OFC in the roles of EQUAL and MASTER has the full read and write ability of OFS, and is in the role of SLAVE The OFC has read-only permissions; [0005] 3. An OFS can only have one connection with the role of MASTER, but it can have multiple connections with ...
