Abstract

The advent of Video On Demand (VOD) services is made possible by specialized high performance, high reliability computer systems. These systems must maintain the constant bandwidth required by video and guarantee fault resiliency. SeaChange®'s digital video system meets the VOD challenges with a scalable cluster solution using a patented data distribution algorithm for efficient data redundancy. The SeaChange digital video cluster incorporates several different bus and fabric technologies to deliver high performance and data reliability. But, the existence of many data paths and congestion scenarios make it difficult to determine the maximum performance of, or bottlenecks in, the system. Therefore, a simulation model to represent the internal fabric of a VOD cluster from SeaChange is designed, implemented and verified.
