Abstract

The invention provides a software defined switching network communication method/system, a readable storage medium and a device. The software defined switching network communication method comprises the following steps: when a network communication request appears in a software defined switching network, calculating a communication path among a virtual switch, a forwarding switch and an external network egress switch; allocating labels for route switching to the virtual switch, the forwarding switch and the external network egress switch; and establishing a label-based data flow table corresponding to the virtual switch, the forwarding switch and the external network egress switch according to the communication path, and issuing the data flow table. According to the software defined switching network communication method/system, the number of SDN network flow tables is effectively reduced by multi-flow table grading, the performance of the switch can be effectively improved, the speedof data communication can be effectively improved, the existing physical SDN switch networking can be supported, the expansion of network functions can be supported, the software defined switching network communication method/system have the ability of adapting to different cloud computing platforms and solve the contradiction between network flexibility and performance in existing cloud computingenvironments.

Description

technical field [0001] The invention belongs to the field of cloud computing and computer networks, and relates to a communication method and system, in particular to a communication method / system, readable storage medium and equipment of a software-defined switching network. Background technique [0002] OpenStack is a very popular technical implementation method for implementing cloud computing platforms. It has become one of the most successful open source projects recognized by the industry, and has also become a recognized private cloud standard in the industry. There are many cloud platform products based on secondary development of OpenStack on the market. [0003] As one of the three key basic resources in the OpenStack cloud platform, the management of the Neutron network is quite complicated, and various network functions and configurations have high requirements for users, and it is very difficult to locate the cause after a problem occurs, and the virtual network...
