Nondestructive continuous extensible interconnection structure for data center

Abstract

The invention discloses a constant degree interconnection structure, which provides interconnection structures with nondestructive and continuous extensible capability, simple and feasible unicast single-path routing methods, and parallel efficient unicast multi-path routing methods for a great amount of common servers and low-end switches, which are respectively provided with two network adapter ports. The interconnection of all servers and switches is completed according to the scale of the data center, the port number of the switches, the layer number of the data center and other requirements, so as to form the nondestructive continuous extensible interconnection structure; the address of a target server is identified according to the data transmission requirement, and a complete path is generated by adopting the unicast single-path routing method, so as to transmit data to the target server; and the address of the target server is identified according to the data transmission requirement, and a plurality of parallel paths are generated by adopting the unicast multi-path routing method, so as to parallelly transmit data to the target server along the multiple paths.

Description

technical field [0001] The invention belongs to the field of data centers and cloud computing, and relates to a lossless, continuously scalable interconnection structure and a supporting routing method of a data center, so that the data center can meet continuous scalability, lossless scalability, Design goals such as high fault tolerance and high cost performance. Background technique [0002] A data center refers to a facility for centralized placement of computer systems and related components (servers, switches, etc.), and includes backup power supplies, current transmission equipment, environmental controls (such as air conditioners, fire extinguishers, etc.) and safety equipment. With the emergence of new application forms such as cloud computing and the Internet of Things, data centers, as an important supporting force, have gradually become the focus of attention in the current academic and industrial circles. Scientists have realized that the further development of...

Problems solved by technology

[0009] (2) In order to realize the lossless scalability of the data center interconnection structure, each server is equipped with a fixed number of network adapter ports. At this time, can the scale of the data center continue to grow and ensure the scalability of the data center from the root? The construction rules of DCell and BCube determine that the maximum size of the corresponding data center has been limited by the number of network adapter ports of its server, so it does not have continuous scalability

If each server of DCell and BCube is equipped with only two network adapter ports, the scale of the data center is very limited and cannot meet the application requirements of 100,000 or even millions of servers

[0010] It is not difficult to find that for the existing server-centric interconnection structures such as Dcell and BCube, its lossless scalability and continuous scalability are a pair of contradictory design indicators, which cannot be achieved at the same time.

That is, in order to ensure lossless scalability, each server is required to be equipped with a fixed number of network adapter ports, so that its continuous scalability cannot be ensured; in order to ensure continuous scalability, each server is required to continuously add new network adapter ports, so then No guarantee of lossless scalability
