Many form of resource sharing have been proposed to improve performance in multipath routing in multimedia to content distribution applications in P2P networks. From the perspective of any single user, throughput is increased by ignoring the interaction among users and by providing parallelism. Focusing on parallelism is by no means sufficient as it ignores the existence of many users with potentially similar strategies. In this paper, we focus on the delay performance of a multiuser system

We use a fork-join queuing model to provide analytical results in a special case of homogeneous users and servers. Our proposed model is simplistic, and yet, it does capture the trade-off between parallelism, traffic load increase, and reassembly /synchronization delay to a large extent. Furthermore, we prove the robustness of a certain locally optimal strategy to non-cooperation in a Nash equilibrium sense.
