Hybrid overlay communication method for data center network

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 ...

AI Technical Summary

Problems solved by technology

[0006] In the traditional networking mode, the communication between the virtual machine switch and the physical switch relies on the multicast exchange of MAC addresses between VTEPs. At the same time, the network throughput is limited by the performance of the virtual machine switch, which is difficult to meet the needs of multi-data center interconnection.
