A Virtual Network to Achieve Low Energy Consumption in Large-scale Datacenter
Yuya Tarutani, Yuichi Ohsita, Masayuki Murata (Osaka Univ.) PN2011-98
Abstract (in Japanese) (See Japanese page) 
(in English) The data center network should provide communication with sufficiently large bandwidth and small delay between all servers so that the data center can handle a large amount of data efficiently. On the other hand, energy consumption of the data center network should be reduced, because energy consumption of the data center network occupies the non-negligible fractions of the total energy consumption in the data center. In this paper, we introduce the virtual network configured over the data center network constructed of the optical cross connects (OXCs) and the electronic switches. We design the VNT so as to achieve sufficiently large bandwidth and small delay with small energy consumption. In our evaluation, We clarify that our method achieves the sufficient bandwidth by using a smaller number of virtual links than the existing data center networks. We also clarify that our method achieves the target maximum number of hops between {\em top-of rack(ToR)} switches by using the similar number of virtual links to the existing data center networks.
