Abstract

Data streaming by swarming over peer-to-peer overlay networks has attracted much attention in recent years and initially the swarming solution is based on data-driven schemes. This paper presents a new request-driven swarming scheme. The scheme offers several advantages: high efficiency in data delivery, low control overhead, and flexibility in streaming control. Some key issues on the design of the relevant scheduling and forwarding mechanisms are discussed. We simulated our proposed request-driven scheme and compared it with an existing data-driven scheme. According to the simulation results, our request-driven scheme incurs much lower control overhead while providing comparable or better efficiency in data delivery.
