Routing method for module-expansion-based data center network topology system

Abstract

The invention discloses a routing method for a module-expansion-based data center network topology system, and mainly aims to solve the problem that the conventional routing methods in the Ethernet and a data center tree network cannot be well applied to the module-expansion-based data center network topology system. The method is implemented by the following steps of: (1) performing initialization, and identifying each piece of network equipment in the topology system by adopting a hierarchical addressing mechanism; (2) reading the addressing information of current network equipment, and judging the type of the current network equipment; (3) generating data, and transmitting the data to edge layer switches by using a source server; (4) determining data output ports according to the destination address of the data and a port with the data by using the edge layer switches, convergence layer switches and intermediate layer switches; and (5), determining a data output port according to the destination address of the data, the hop number of a path hop number and the cache information of the port by using core layer switches. The method has the advantages that: network throughput is improved; traffic balancing is realized; the method can be used for the path selection of a data center network and the provision of high-efficiency data transmission service; and the shortcomings of static routing are overcome.
