Problems solved by technology

[0007] When the Bcube structure expands the network, the number of servers increases in multiples of the number of ports of a switch for each layer of expansion. When a switch with a small number of ports is used, the expansion speed is slow. When a switch with a large number of ports is used, although The expansion speed is fast, but the switch with a large number of ports is expensive, which will lead to higher costs

Abstract

The invention discloses a data center network structure and a routing method thereof, and belongs to the field of computers. The data center network structure comprises k layers of networks, wherein k>1 and k is an integer. When k> / =2, the kth layer of network comprises bn (k-1)th layers of networks and n(bn)k-2 sets of the kth layer switches. Each set of the kth layer switches comprises b the kth layer switches. One matrix of bn rows and n(bn)k-2 columns is formed by servers in the bn (k-1)th layer networks. The bn servers of each column of the matrix are correspondingly connected with one set of the kth layer switches. The first to the kth layers switches are n-port switches, wherein 2n> / =b>1 and b is the integer. The kth layer network is formed by the bn(b>1) (k-1)th layer networks, and the number of the servers is increased by bn times of the original when one layer of network is additionally arranged by a data center network so that expansion speed is ensured to be rapid, and great cost caused by high price of application of multiport switches can be avoided.

Description

technical field [0001] The invention relates to the computer field, in particular to a data center network structure and a routing method thereof. Background technique [0002] A data center is a complete set of complex facilities, including large-scale computer systems (such as server farms) and other supporting equipment (such as network equipment such as switches and storage systems, etc.), as well as redundant data communication connections, environmental control, etc. equipment, monitoring equipment and various safety devices. Among them, the data center network structure is the core part of the data center, which is used to connect thousands of servers using network devices such as switches, and provide a path between any two servers, and this path must meet high-bandwidth, high-speed , good scalability and low cost. [0003] Currently, there are some typical data center network structures in the industry, mainly including Portland, VL2 (Virtual Layer 2, Virtual Laye...
