A topology reconfiguration control method for optical network

Abstract

The present invention provides a topology reconfiguration control method for an optical network, comprising: 1) acquiring the bandwidth provided by the optical network for the lines between each network node to generate a current bandwidth matrix; 2) acquiring the bandwidth of each network in the application scene load requirements between nodes to generate a demand matrix; 3) comparing the current bandwidth matrix with the demand matrix, and performing topology reconfiguration if the current bandwidth matrix does not meet the demand matrix.

Description

technical field [0001] The invention relates to an optical interconnection network, in particular to topology reconfiguration of the optical interconnection network. Background technique [0002] In recent years, the Internet industry has developed rapidly, and new network applications have been introduced continuously, which has led to a rapid increase in the number of Internet users; with the rise and development of the cloud computing industry, a large number of enterprises deploy their services to private or public cloud computing clusters, and the concentration of application deployment makes the scale of data centers Growing. Large-scale data centers carry many different types of applications such as big data processing, Internet applications, cloud computing, and scientific computing. Existing data centers use a fixed and single interconnection network structure to achieve high scalability, but it is difficult to efficiently meet multiple The requirements of various ...

Problems solved by technology

Most existing technologies cannot guarantee a fast, uninterrupted, and orderly process of topology reconfiguration

This is because, in different application scenarios, the network also has different requirements for the traffic load of each area. However, most of the existing technologies do not consider selecting the appropriate destination topology for different network requirements, rather than optimal The purpose topology is often difficult to make the reconstruction process develop in a direction that is beneficial to the throughput and delay of the entire network

Moreover, the reconstruction preparation time of most existing technologies is relatively long. For example, the calculation of the intermediate topology of the existing dynamic topology reconstruction occupies most of the preparation time, making it difficult to quickly realize topology reconstruction. During the reconstruction process It brings unnecessary waste to the use of network resources
