Abstract

The invention discloses a resource control method, device and system of OpenFlow protocol, which are used to solve the problem of insufficient utilization of forwarding resources. A method provided by the present invention may include: a controller sends a resource allocation request message to a repeater, and an OpenFlow interface is established between the controller and the repeater; the controller receives a response from the repeater to the repeater; A resource configuration message sent by a resource allocation request message, the resource configuration message includes: idle forwarding resources acquired by the forwarder from the total forwarding resources; The created service allocates service available forwarding resources, and the service available forwarding resources are part or all of the idle forwarding resources.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a resource control method, device and system of the OpenFlow protocol. Background technique [0002] OpenFlow is a communication protocol defined by the Open Networking Foundation (English: Open Networking Foundation, ONF). OpenFlow is used in software-defined networking (English: software-defined networking, SDN) to provide access from a controller (English: controller) to a forwarder (English: forwarder). SDN is characterized by openness, programmability, and support for separation of control and forwarding. [0003] The principle of SDN technology is to abstract the forwarding process into two objects: matching (English: match) and instruction (English: instruction). The forwarding process of the message is to match the flow table according to the message information, and execute according to the instruction specified in the flow table after matching. Forward....
