Embodiment 1

[0011] A kind of unicast VXLAN management steps based on Linux bridge and SDN controller, including the management steps of Linux bridge and vtep, the management steps of Layer 2 addressing (FDB forwarding table), and the sequence management steps between bridge-vtep and FDB Part, the management step of described Linux bridge and vtep is based on Redis Queue (abbreviation RQ) and Consumer, realizes the management of two-layer virtual switch and vtep (vxlan tunnel terminal); Described two-layer addressing (FDB forwarding table) The management steps: based on etcd and watch, realize the management of the FDB forwarding table, the sequence management steps between the bridge-vtep and the FDB: controlled by the order of the SDN controller operation, to ensure that the linux bridge and vtep have priority over the FDB forwarding post exists.

Embodiment 2

[0013] As an optimization, the management steps of the described Linux bridge and vtep are as follows: step a, the SDN controller sends the request to create or delete the linux bridge and vtep to the RQ message queue; step b, the consumer on the VM host computer and the RQ keep Connect, create or delete linux bridge and vtep according to the content of the message after receiving the message from RQ.

Embodiment 3

[0015] As an optimization, the management steps of the two-layer addressing (FDB forwarding table) are: step c, the SDN controller sends the information of creating the FDB table entry to the registration center (etcd is used here); step d, the VM host machine The watch on the server is connected to etcd, and after discovering new information on etcd, it operates the local FDB to communicate with other hosts through the tunnel network, and vtep establishes a tunnel with the host with the same vxlan id.

Abstract

The invention discloses a unicast VXLAN management method based on Linux bridge and SDN controller, the method steps include the management steps of Linux bridge and vtep, the management steps of two-layer addressing and the sequence between bridge-vtep and FDB The management step has three parts.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a unicast VXLAN management method based on a Linux bridge and an SDN controller. Background technique [0002] With the rapid development of information technology, the construction of data centers has gone through decades. In fact, the server architecture currently in use has been in use for decades, and existing problems have surfaced. The emergence of blade servers has taken the architecture design of servers a step forward; however, it has also brought about the problem of scattered storage resource utilization. Although the numerous network devices and storage devices in the data center are connected through the network, they are actually independent groups. The integration, optimization, intensification and integrated design of data center equipment have been put on the agenda. Improve the efficiency of the server and the performance of the entire data center, sa...
