Method for routing data centre network system

Abstract

The invention relates to a method for routing a data centre network system. The data centre network system comprises row head exchangers, line head exchangers and access exchangers, wherein the access exchangers are arranged in the form of a matrix; at least one row head exchanger is deployed at the row head of each row; at least one line head exchanger is arranged at the line head of each line; and servers are connected with the access exchangers which are connected with all row head exchangers in the rows of the access exchangers and all line head exchangers in the lines of the access exchangers. In the invention, the servers in the same sub network communicate with each other through the access exchangers connected with the servers; and the servers of different sub networks communicatewith each other through the access exchangers, the row head exchangers and the line head exchangers. The routing method provided by the invention has the advantages of simplicity, high efficiency, convenience for realization through hardware and high routing speed.

Description

technical field [0001] The invention relates to a routing method, in particular to a routing method for a data center network system. Background technique [0002] The data center is the provider center of various application services of the enterprise, and the center of data calculation, exchange and storage. It combines advanced network technology and storage technology, carries more than 80% of the service requests and data storage capacity in the network, and provides services and operating platforms for the healthy operation of customers' business systems. [0003] Data centers first appeared in the early 1960s. With the rapid construction of the Internet and the rapid development of information technology, the data center entered a period of vigorous development in the middle and late 1990s, and the construction scale and the number of servers increased at an alarming rate every year. The vigorous development of Internet technology has set off a climax in the constru...

Problems solved by technology

[0006] Although the above network structure solves the upper-layer bandwidth bottleneck problem of building a large-scale data center network, it still has the following disadvantages: (1) Due to the limitation of its topology structure, the oversubscription (Oversubscription) ratio of network traffic is difficult to be flexible according to actual needs (2) Its network topology is relatively complex, device addressing needs to follow strict and complex rules, and device ports are connected in strict order. Deployment is cumbersome, and network maintenance during operation is relatively difficult; (3) Due to the complex topology, its routing algorithm is relatively complex; (4) When building a small-scale data center network, there will be ports In the case of wasted space, the network scalability is poor
