Virtual Structured P2P Network Topology for Distributed Computing

P2P and grid computing are two paradigms more and more used in today computing environments; their potential to provide better quality of service to users is very promising compared to the cost it involves. This paper presents a hierarchical virtual network topology, built on top of the real existing one and which is used to manage distributed resources in grid environment. The distributed resources are found on the Web following P2P techniques; and so they are very volatile. The virtual topology constructs an efficient and robust virtual machine which will serve as a distributed computing platform. This topology is called TreeP and it is exploited in DGET by Hudzia, B. et al, (2005); a data-grid middleware environment. Here, we study this virtual topology both theoretically and experimentally. We show that this topology is very scalable, robust, load-balanced, and easy to construct and maintain
