Abstract

The invention belongs to the technical field of optical communication, and particularly relates to a free space optical data center network architecture and a topology reconstruction system and method.The data center network architecture comprises N servers, M cabinets, polarization controllers, 1 * 2 couplers and metasurface free space optical exchangers, each cabinet is internally provided with N/M servers, each server is provided with a polarization controller and a 1 * 2 coupler, the network architecture improves the short-distance high-speed dense information exchange capability of the servers, and also can realize high bandwidth transmission rate and low network energy consumption; the reconstruction system comprises an LSTM-based flow prediction module, a reconstruction trigger judgment module and a topology generation module, and the system and the reconstruction method based on the system can effectively improve the network bandwidth, achieve a higher network resource utilization rate, and fully improve the performance of the free space optical data center architecture.

Description

technical field [0001] The invention belongs to the technical field of optical communication, and in particular relates to a free space optical data center network architecture, topology reconstruction system and method. Background technique [0002] The data center supports many user-oriented applications, including 5G, big data, cloud services, content delivery, etc. It also carries bandwidth-intensive services such as neural networks, artificial intelligence, and the Internet of Things. The rapid development of these applications and services has brought great challenges to the data center as the core infrastructure. At the same time, the data center interconnection network serves as the main carrier for short-distance, high-speed intensive information exchange between servers, including links for transmitting information, and switches for forwarding information received from input links to designated output links. Rising has placed higher bandwidth demands on data cente...
