Enabling Robust Network Fault Tolerance for IP-Based Surveillance Systems

Abstract

One of the most critical disadvantages of the IP- based surveillance is the network reliability problem. That is, since the IP-based surveillance system is IP-based, all of the services provided by the IP-based surveillance system will not be accessible at all if network failure occurs. In this paper, a network-fault-tolerable IP-based surveillance (NeTSurv) system is proposed. In addition to the existing features of current video surveillance systems, a multihome-based approach is adopted to improve the network fault tolerance capability of the NeTSurv system. Furthermore, the fault tolerance mechanism is developed to solve the connectivity issue and the continuity issue of video playout for different link failure scenarios.
