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.
