Abstract

An embodiment of the present invention provides a method for sending a connection establishment request, the method comprising: the OpenFlow switch sends a parameter request message to the configuration server, and the parameter request message is used to request to obtain the connection parameters of the OpenFlow controller; The flow switch receives the Internet Protocol IP address sent by the configuration server and the connection parameter set of the OpenFlow controller, the connection parameter set includes at least the connection parameter of the first OpenFlow controller; the OpenFlow switch according to the configuration server The sending IP address and the connection parameters of the first OpenFlow controller send a connection establishment request message to the first OpenFlow controller, the embodiment of the present invention also provides an OpenFlow switch, a configuration server and a sending The system for establishing a connection request can automatically establish a connection between the OpenFlow switch and the OpenFlow controller through the technical solutions provided by the embodiments of the present invention.

Description

Technical field [0001] The embodiment of the present invention relates to the field of communication technology, and in particular to a method for sending a connection establishment request, an OpenFlow switch, a configuration server and a system. Background technique [0002] With the continuous maturity and development of network technology, the separation of control and forwarding is a trend. Openflow provides a new type of network model. OpenFlow Network can include two types of equipment: OpenFlow Control (OpenFlow Controller) and OpenFlow Switch (OpenFlow Switch). The OpenFlow controller is responsible for centralized control of the network and delivers a flow table to the open switch. At the same time, the OpenFlow controller is open to users. The OpenFlow switch performs packet matching and forwarding according to the flow table. In this way, the user defines the flow on the open flow controller and controls the path of the flow in the network, thereby releasing the cont...
