摘要:
A method and apparatus for downloading content within a video-on-demand system is provided herein. During operation a Video Home Office (VHO) will cache a subset of the Video Service Office (VSO) content. When a user requests content that is not stored on the VHO, the VHO will request that content from another VHO or the VSO. In order to reduce the additional network load imposed during item forwarding while attempting to balance the total load on all the links interconnecting the VSO and VHOs, recorded traffic history metrics are used to predict their future or current traffic. A VHO or VSO is chosen for fetching the content that will result in the lowest predicted traffic on the interconnecting links.
