Case Study II: Resource Management of Network Virtualization

Abstract

Network virtualization is an emerging trend claimed to reduce the costs of future networks. The key strategy in network virtualization is of slicing physical resources (links, routers, servers, etc.) to create virtual networks composed of subsets of these slices. One important challenge is the resource management of the physical or substrate networks. Sophisticated management techniques should be used to accomplish such management. Self-management techniques rise as an appropriated alternative to address such a challenges on network virtualization. This chapter depicts the joint use of self-organizing property and P2P technique according to the principles of the Self-* P2P design in order to manage the substrate network resources. The concepts behind self-organizing P2P approach are presented as well as the network virtualization model considered in this work. Then the instantiation of the generic self-organizing P2P solution on the network virtualization environment is depicted, its implementation and summary evaluation of the solution are also described. An evaluation of the self-organizing P2P solution is discussed and the final remarks of this case study presented.
