ABSTRACT:
The present invention relates generally to a system for managing bandwidth usage in a content delivery system such as a Video on Demand (VOD) network. Specifically, an Edge Resource Manager (ERM) makes use of a number of policies to optimally select a transmission device such as a Quadrature Amplitude Modulation (QAM) device. The policies aid in providing efficient use of the transmission devices particularly when a number of different transmission rates for different media are employed.
