Embodiment Construction

[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be described in detail below in conjunction with the embodiments. It should be noted that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] In this data center network hybrid overlay communication method, vSwitch hosts and EVPN network element devices based on different implementation methods are managed to the SDN controller through OpenFlow; the SDN controller uses the OVSDB management protocol to deliver configurations to the vSwitch host through Rest and RPC And the control flow table, using the NetConf protocol to control the interface configuration and network policy of the EVPN network element; the Underlay network uses the OSPF protocol to publish the management IP of the EVPN network element to the data link, and connect the ...

Abstract

The invention particularly relates to a hybrid overlay communication method for a data center network. According to the hybrid overlay communication method for the data center network, a vSwitch hostand EVPN network element equipment based on different implementation modes are managed to an SDN controller through OpenFlow; the SDN controller uses an OVSDB management protocol to issue a configuration and control flow table to the vSwitch host through Rest and RPC modes, and uses a NetConf protocol to control interface configuration and a network strategy on an EVPN network element; the underlay network publishes a management IP of an EVPN network element to a data link by using an OSPF protocol, and connects a vSwich host and the EVPN network element through a routing switch, thereby realizing two-layer interconnection between devices, and realizing fusion of different types of data centers from a control layer and a data layer. According to the hybrid overlay communication method forthe data center network, the fusion of different network architectures on the same platform is solved, the expandability and extensibility of the network are improved, the management cost is reduced,and the network communication quality is greatly improved.

Description

technical field [0001] The invention relates to the technical field of computer network communication, in particular to a method for data center network hybrid overlay communication. Background technique [0002] With the advent of the Internet + era, high-tech technologies such as cloud computing, big data, and virtualization are undergoing a technological innovation. Global Internet companies are also looking for opportunities to expand their data centers, establish higher-speed, more efficient, more convenient, and more user-friendly system models, and occupy a place in the Internet + era. [0003] In the traditional networking mode, the server access can be a virtual switch or a physical switch, so there are three different construction modes: network overlay, host overlay, and hybrid overlay: in the network overlay solution, all terminals use physical switches As a VTEP node; in the host overlay solution, all terminals use virtual switches as VTEP nodes; in the hybrid ...
