Paper Abstract

We address the problem of content delivery network for HD-VoD service. Content delivery network (CDN) is a network that puts users closer to the storage resources. The conventional CDN structure for video delivery is based on the IP-over- WDM network which could not meet the requirements for HD-VoD service, such as high-speed transfer and low latency and jitter. A novel all-optical CDN network model for high-definition VoD service is proposed in this paper. We introduce the concept of optical timeslot in the lightpath provision. A mini-control plane mechanism based on ring topology is also designed for the fast optical timeslot setup/release. Simulation results and analysis of our model is showed at the end of paper.
