Project title: Energy-Aware Virtual Data Center Embedding

Over the last decade, the use of computer networks has greatly increased, leading to new research areas like Software Defined Networks (SDNs). This type of network separates the decision-making process on a physical switch or router to an external controller. These controllers can manage a large number of devices and has its advantages such as error free convergence, learning networks etc.

To make this technology scalability and profitable for Internet Service providers, my research focuses on the introduction of a layer of virtualisation between the underlying hardware and a software controller.

Considering virtualisation at a higher scale, infrastructure can be provided as a service, where multiple tenants can lease resources for a price. Having multiple tenants such as Internet Service Providers (ISPs) would like to host their own software controller for their network.

Recently there has been a lot of interest in this possibility as it is more economical in the long run, enables performance on demand and provides services cheaper for end users with better services. Hence recent research is looking at merging SDNs and Virtualisation to give Virtualised Software Defined Networks
(vSDNs).

My study analysis the impact of virtualisation in terms of latency, cost and intra/inter provider handovers of data. It also looks at the efficiency of virtual SDNs to non virtual SDNs.
