Sago: A Network Resource Management System for Real-Time Content Distribution

Abstract— Content replication and distribution is an effective technology to reduce the response time for web accesses and has been proven quite popular among large Internet content providers. However, existing content distribution systems assume a store-and-forward delivery model and is mostly based on static content. This paper describes the design, implementation, and initial evaluation of a network resource management system for real-time Internet content distribution called Sago, which provides facilities to provision and allocate network resources so that multiple bandwidth-guaranteed and fault-tolerant multicast connections can be multiplexed on a single physical network. Sago includes a novel network resource mapping algorithm that takes into account both physical network topology and dynamic traffic demands, a network-wide fault tolerance mechanism that supports both node-level and link-level fault tolerance, and a hierarchical network link scheduler that provides performan...
