Embodiment 1
[0146] Such as figure 2 As shown, on the controller side of the Openflow system, the embodiment of the present invention provides a flow entry generation method, including:
[0147] S201, the controller of the Openflow system generates a first flow entry and a second flow entry, and the first flow entry and the second flow entry are used by the switch of the Openflow system to operate on the tenant message;
[0148] The first flow entry indicates that the tenant information of the tenant message is associated with the tunnel information, the tenant information is used to identify the tenant to which the tenant message belongs, and the tunnel indicated by the tunnel information is used to transmit the tenant message to the switch; the second flow entry is used It is used to operate tenant packets according to tenant information and tunnel information;
[0149] S202. The controller sends the generated first flow entry and the second flow entry to the switch.
[0150] Optional...
Embodiment 2
[0218] Such as Figure 10 As shown, on the controller side of the Openflow system, the embodiment of the present invention provides a flow entry generation method, including:
[0219] S1001, the controller of the Openflow system generates a flow entry, and the flow entry is used for multicasting tenant messages of switches in the Openflow system;
[0220]The flow entry indicates that the outgoing port information of the tenant message is associated with the tunnel information, the tunnel indicated by the tunnel information is used to transmit the multicast tenant message of the switch, and the outgoing port indicated by the outgoing port information is used for the multicast tenant message;
[0221] S1002. The controller sends the generated flow entry to the switch.
[0222] In this embodiment, the flow entry generated by the controller of the Openflow system includes a matching field and an operation field, the matching field carries the ingress port information of the tenan...

Abstract
The invention provides a method for generating a flow table item to realize the operation of tenant messages based on the Openflowsystem. The method of the present invention includes: the controller of the Openflowsystem generates the first flow table item and the second flow table item, and the first flow table item and the second flow table item are used for the switch of the Openflowsystem to operate the tenant message; the first flow table item indicates The tenant information of the tenant message is associated with the tunnel information, the tenant information is used to identify the tenant to which the tenant message belongs, and the tunnel indicated by the tunnel information is used to transmit the tenant message to the switch; the second flow entry is used to The tunnel information operates on tenant packets; the controller sends the generated first flow entry and second flow entry to the switch.
Description
technical field [0001] The present invention relates to the communication field, in particular to a method for generating and receiving a flow entry, a controller, a switch and a system for generating a flow entry. Background technique [0002] With the development of the Internet, today's Internet services have put forward higher and higher transmission quality requirements for the Internet, and the OpenFlow system has been proposed to meet the needs of new services. The OpenFlow system mainly includes an OpenFlow switch (OpenFlow Switch) and a controller. The OpenFlow system converts the original message forwarding process completely controlled by the switch / router into a joint completion of the OpenFlow switch and the controller, thereby realizing message forwarding and routing control. separation. The controller can control the flow entries in the switch through pre-specified interface operations, so as to achieve the purpose of controlling packet forwarding. [0003] ...
