SDN resource allocation method based on multi-homing structure of two-sided market

Abstract

The invention discloses an SDN resource distribution method based on a two-sided market multihoming structure. The SDN resource distribution method based on the two-sided market multihoming structure comprises the steps that firstly, an SDN resource distribution frame is divided into a customer layer, a control layer and a retailer layer; secondly, after the customer layer receives application requests of different users, summarizes the application requests into a request information list and transmits the request information list to the control layer through a northbound interface; thirdly, the retailer layer transmits resource information to the control layer in real time through a southbound interface; fourthly, the control layer comprises a plurality of independent control platforms, each control platform receives the resource information from the retailer layer and sends the resource information and expense information of the control platforms to the customer layer, and the users in the customer layer carry out selection from the multiple control platforms according to the self needs; fifthly, each customer requires needed resources from the multiple control platforms, and carries out selection according to a resource cost-performance ratio provided by each control platform by using a resource combination strategy. The SDN resource distribution method based on the two-sided market multihoming structure meets the requirements for tasks of users, makes full use of network resources, and improves the reliability of the network.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to an SDN resource allocation method based on a bilateral market multi-homing structure. Background technique [0002] So far, the Internet has been developed for more than 40 years, and many countries in the world have built it as an important social infrastructure, which has changed the way of life and work of human society to a large extent. However, with the continuous development of wireless communication, transmission technology, and computing technology, as well as the emergence of new applications such as the Internet of Things, social networks, high-traffic video services, and 3DTV, the existing Internet architecture is increasingly unable to keep up with the growing demand . The switches, routers, and other devices used to build networks have become extremely complex because they implement a growing number of distributed protocols standardized by organizations such a...

Problems solved by technology

In the face of new demands, the main deficiencies of the original hierarchical data center of the Internet include: limited server-to-server connection and bandwidth, small scale, scattered resources, high cost of vertical expansion, low routing efficiency, large configuration overhead, and no Traffic isolation between services and network protocols need to be improved, etc.
