Abstract:
Over the last years, the complexity and variety of services available on the Internet increased. This fact is leading to the search for efficient techniques of routing client requests to the best server available. A known technique is the application layer anycast.

Anycast is an IP layer technique used to deliver datagrams from a client to one server among many. The definition says that an IP (Internet Protocol) address maps to a group of servers that offer the same service. The application layer anycast concept utilizes the same strategy as the IP layer anycast, but in the application layer. This brings much more flexibility to the system, such as the variety of metrics that can be used on the selection of the best server.

In this seminar I will present my work. Its main goal is to elaborate efficient ways to provide application layer anycast with quality of service in the context of cloud computing. I will present the progress so far, including new strategies adopted and results through simulations. Also, I will talk about our current work, a real prototype deployment to validate our results.
