Evaluation of the Placement of Network Services
Todd Sproull, Roger D. Chamberlain · 2011
Abstract — Network services are used in the Internet today for a variety of functionality, from Voice Over IP (VoIP) relays to network game servers. Determining the placement of these network services and measuring the quality of the placement in realistic scenarios is a challenging problem. This paper explores different methodologies for evaluating the placement of network services. The strategies include: simulations of with thousands of nodes, emulation of different topologies with hundreds of nodes, and Internet deployment for a diverse selection of nodes and network communications. In addition, comparisons to a centralized communication model are studied. This range of exploration enables a better understanding of the impact the selection of supernodes provides on a variety of applications and platforms. 1.
