New video-on-demand service architecture using multi-spread path to guarantee QoS

A new Video-on-Demand (VOD) Service architecture is put forward and spreading VOD data through multi paths on application layer is achieved. The new architecture can reduce the influence of band-width fluctuation on QoS of VOD service and can overcome the defect of traditional architecture because of a single routing congestion under too many VOD data or other reasons when the QoS of service can't guarantee. The protocol and arithmetic of multi-spread paths are given out. The experiment proves that the new architecture can lighten the pressure on a single routing service for VOD, especially on main VOD server, and the spreading of VOD data can change the band-width, and can guarantee QoS of VOD service better than traditional one.
