D-MORE: Dynamic mesh-based overlay peer-to-peer infrastructure

Traditionally, Internet Service Providers (ISPs) have to interconnect with content providers to provide network services to customers. Current business model that connectivity and bandwidth become commodities has motivated ISPs to distribute content and other application-specific services to their customers using their own infrastructure. It is desirable for ISPs to economize existing infrastructure to support a variety of applications and services. We propose a dynamic mesh-based overlay peer-to-peer infrastructure and illustrate its two examples usage cases among other potentials. We describe several key techniques, namely capacity classification, locality-awareness and incentive mechanisms for construction of the tiered infrastructure. Through extensive simulations, we show D-MORE scales well with an increasing number of hosts, in terms of control overhead, link stress and data path length, for supporting media distribution services. We propose further improvements to enhance the D-MORE performance, which brings up to 35% network resource savings and up to 200% control overhead reduction in our simulations.
