Problems solved by technology

[0012] If the OpenFlow controller delivers the flow table incorrectly or the VEPA switch is faulty, a loop may occur between port 3 and port 4, which will cause the traffic to fail to be forwarded normally, and the upstream and downstream traffic to be forwarded chaotically, resulting in abnormality of the switch and server, and even network failure. paralysis

Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0027] In the embodiment of the present invention, a LACP loop detection method based on the OpenFlow protocol is proposed. The method is applied to a server in a network including an OpenFlow controller, a server and an edge switch. The server virtualizes a plurality of virtual machines VM and a The virtual edge port aggregates the VEPA switch, and the uplink port of the VEPA switch is aggregated with the downlink port of the edge switch to form an aggregation group.

[0028] The VEPA switch adds the uplink ports that need to be aggregated to an aggregation group, and the edge switch adds the downlink ports that need to be aggregated to an aggregation group. The VEPA switch and the edge switch send LACP packets through the uplink ports ...

Abstract

The present application discloses an OpenFlow protocol based link aggregation control protocol (LACP) loop detection method comprising: a virtual edge port aggregation (VEPA) switch periodically sending a link aggregation control protocol data unit (LACPDU) message to the edge switch via each of uplink ports in an aggregation group for loop detection; when receiving an LACPDU message for loop detection sent locally via any uplink port in the aggregation group, determining a loop is generated between the VPEA switch and the edge switch, keeping one uplink port in the aggregation group running normally, and shutting down the rest of the uplink ports. On the basis of the same inventive idea, the present application further presents a device, which is able to ensure the normal forwarding of traffics between the VPEA switch and the edge switch.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a Link Aggregation Control Protocol (Link Aggregation Control Protocol, LACP) loop detection method and device based on the OpenFlow protocol. Background technique [0002] With the increasing business of data centers and the continuous improvement of user requirements, the scale and functions of data centers are becoming more and more complex, and the management difficulty is also becoming more and more difficult. In this context, integrating data centers, reducing data center management costs, and fully exploiting existing resource capabilities to meet higher business needs have become important tasks for enterprise data centers. Virtualizing data center resources has become an important trend in data center integration. [0003] Virtualization technology abstracts physical resources and provided services, so that resource users and system managers do no...
