Dynamically provisioned virtual clusters provide a means of consolidating servers in a data center and for supporting utility computing. Data centers typically sport a large number of (layer 2) switches and very few routers, yet, the existing layer-2 QoS are not well developed. This paper proposes the notion of virtual link as an interconnection abstraction to provide granular QoS. The paper also presents an experimental study comparing virtual link based congestion control against other alternatives for emerging 10 Gb/sec Ethernet links. It is shown that virtual links can provide desired capabilities with a small perturbation to existing standards and can work well in mixed legacy environments.
