Embodiment Construction

[0027] The multi-branch fat tree network topology is applicable to most system interconnection switch hardware, including Myrinet, Infiniband, Quadrics, etc. The following uses the Myrinet switch as an example to illustrate the specific implementation method of the multi-branch fat tree network topology.

[0028] The Myrinet products we will use include M3-E128, port link card, and cascade link card. Among them, M3-E128 is a switch cabinet with 128 ports. Each switch cabinet has 8 built-in 16-port switches. If all 16 port link cards are inserted, a maximum of 128 ports can be provided. The port link card is a down link card with a built-in 16-port switch, and each card provides 8 down link ports. The cascading link card is an uplink connection card, and each card provides 8 uplink connection ports.

[0029] We take the three-branch fat tree topology as an example to illustrate its specific implementation method. The three-branch fat tree topology requires three M3-E128 port ...

Abstract

When numbers of node in network increases to a certain scale, network topology interconnection techniques between exchangers are produced. Synthesized interconnection mode of fat tree topology and full net topology is utilized in the invention, that is to say fat tree interconnection is utilized for each branch and full net interconnection mode is applied among branches. Based on number of branch, two branches fat trees, three branches fat trees and four branches fat trees are named. Comparing with network topology structure of nonblocking fat tree under condition of the same number of exchnger, the invented structure possesses advantages of available large scale of networked scale, lowered communication delay, and higher rate of performances/cost.

Description

1. Technical field [0001] The invention relates to the field of computer and communication, and is a fat tree network topology system structure, in particular a multi-branch fat tree topology structure formed by the comprehensive interconnection of the fat tree topology and the whole network topology. 2. Technical background [0002] With the continuous development of network technology and the explosive growth of network scale, especially the construction of large-scale computer cluster systems, it is necessary to stack switches to support more ports. To this end, it is necessary to design the topology of the switch stack to meet the actual application requirements. [0003] There are many methods for topological design of switch stacking, and there are also many topological structures that have been formed, such as full network structure, hypercube structure, fat tree structure, butterfly tree structure, and so on. The most concerned issues in designing network topology a...
