VolvoxDC : A new scalable data center network architecture

Abstract

To contend with increasing requirement of cloud based applications nowadays, it is becoming very essential for the data center networks (DCN) to expand the network capacity very frequently. A good DCN topology must possess several properties for any dimensions of the network such as low diameter, high bisection bandwidth, low cost of deployment etc. Moreover, a DCN topology must also show efficiency in terms of scalability, failure resiliency, routing and construction. In this paper, we propose a novel DCN topology named VolvoxDC which resembles the structure of the similar named multi-cellular Algae Volvox which consists of thousands of cells within it. VolvoxDC is built up with several modules connected via perfect matchings and each module is constructed from an arbitrary diameter 2 graph. VolvoxDC shows excellent topological properties and it outperforms significant topologies like Fattree and Jellyfish in terms of providing a better cost effective design with more capacity.
