An approach to peer selection in service overlays

Networking services are increasingly being provided by peer-to-peer service overlay networks (P2P SON), allowing service providers to cooperatively offer and run a flexible set of services. In this respect, the selection of peers is a key issue for improving resource usage and end users Quality of Experience (QoE). This paper presents an approach to best peer selection in a three-tier P2P SON architecture, allowing the splitting of service business functions and peer selection functions. The proposed best peer selection approach is evaluated by simulation, using a 5-dimension distance metric available in the literature and real delay, jitter and geographical positioning made available by the CAIDA project and MaxMind's free database. The simulation results show the consistency and good performance of the proposed peer selection approach.
