The network aspect of Infrastructure-as-a-Service

Current service platform offers that provide Infrastructure as a Service (IaaS) do not adequately meet the requirements expressed by interactive real-time services. Online application response times can not yet be enforced in virtual infrastructures without service level objectives (SLOs) that meet virtual machine interconnection constraints. This paper presents a framework spanning from the service description model over the IaaS platform interface for service level agreement (SLA) negotiation to the management of virtual network resources in an IaaS environment.
