A data center mesh network and connection method

Abstract

The invention relates to a data center MESH network and a connection method. The data center MESH network provided by the embodiment of the invention comprises K<2> CAWGs (Coaxial Adapter Waveguides) and K switch groups, wherein each switch group comprises N switches, and is interconnected in intra-group connection and inter-group connection ways; each switch comprises KxN connection ports and K pairs of receiving-transmitting ports; each pair of receiving-transmitting ports comprises a transmitting port and a receiving port; in intra-group connection, N switches in each switch group are connected with N switches in the same group through one CAWG; in inter-group connection, each of the N switches in each switch group is connected with N switches in any other switch group in the K switch groups through another CAWG respectively. Through adoption of the data center MESH network and the connection method provided by the embodiment of the invention, the defects in the prior art can be overcome. Connection of a large-capacity data center MESH network is realized by the CAWGs; the large capacity demand of a future data center network is met; the quantity of used optical fibers is reduced; and the physical space of a machine room is saved.

Description

technical field [0001] The invention relates to network communication technology, in particular to a data center MESH network and a connection method. Background technique [0002] Existing data centers require the joint action of the access layer, aggregation layer and core layer to realize the connection between all servers. The physical network of the data center uses optical fiber to realize the connection between switches, and each pair of ports occupies a pair of optical fibers. , When the scale of the data center network is large, tens of thousands of pairs of connecting optical fibers are required, which greatly occupies the physical space of the computer room. Moreover, data center network traffic is developing at a compound annual growth rate of 50%, and P-level data centers will appear in large numbers in the next few years. The capacity of existing technology data centers is directly limited by the capacity of core switches, and it is difficult to achieve future ...
