Openflow protocol-based resource control method and system, and apparatus

An OpenFlow protocol-based resource control method, comprising:

• receiving, by a forwarder, a resource allocation request message sent by a controller, wherein an OpenFlow interface is established between the forwarder and the controller;
• obtaining, by the forwarder, an idle forwarding resource from total forwarding resources according to the resource allocation request message;
• and
• sending, by the forwarder, a resource configuration message to the controller, wherein the resource configuration message comprises the idle forwarding resource obtained by the forwarder.

A controller, comprising:

• a sending module, configured to send a resource allocation request message to a forwarder, wherein an OpenFlow interface is established between the controller and the forwarder;
• a receiving module, configured to receive a resource configuration message from the forwarder, wherein the resource configuration message is sent by the forwarder in response to the resource allocation request message, and the resource configuration message comprises an idle forwarding resource obtained by the forwarder from total forwarding resources;
• and
• a resource allocation module, configured to allocate, according to the idle forwarding resource, a service-accessible forwarding resource to an already created service on the controller, wherein the service-accessible forwarding resource is some or all resources in the idle forwarding resource.

A forwarder, comprising:

• a receiving module, configured to receive a resource allocation request message sent by a controller, wherein an OpenFlow interface is established between the forwarder and the controller;
• a resource management module, configured to obtain an idle forwarding resource from total forwarding resources according to the resource allocation request message;
• and
• a sending module, configured to send a resource configuration message to the controller, wherein the resource configuration message comprises the idle forwarding resource obtained by the forwarder.

A controller, comprising a network interface and a processor, wherein

• the network interface is configured to implement OpenFlow protocol-based communication with a forwarder;
• and
• the processor is configured to:
• send a resource allocation request message to the forwarder;
• receive a resource configuration message from the forwarder, wherein the resource configuration message is sent by the forwarder in response to the resource allocation request message, and the resource configuration message comprises an idle forwarding resource obtained by the forwarder from total forwarding resources;
• and
• allocate, according to the idle forwarding resource, a service-accessible forwarding resource to an already created service on the controller, wherein the service-accessible forwarding resource is some or all resources in the idle forwarding resource.

A forwarder, comprising a network interface and a processor, wherein

• the network interface is configured to implement OpenFlow protocol-based communication with a controller;
• and
• the processor is configured to:
• receive a resource allocation request message sent by the controller;
• obtain an idle forwarding resource from total forwarding resources according to the resource allocation request message;
• and
• send a resource configuration message to the controller, wherein the resource configuration message comprises the idle forwarding resource obtained by the forwarder.
