Multiple System Operators (MSOs) throughout the Cable Industry are planning to roll out IP video services. Many MSOs hope to eventually migrate these IP Video Services to their DOCSIS 3.0 infrastructure in an effort to capitalize on many benefits, including the statistical multiplexing gains of channel bonding, the QoS that permits partnerships with other Internet content providers, and the simplicity of a single delivery system.
One particular challenge to this planned migration is created by the fixed amount of bandwidth available on the HFC plant to support simultaneous deployment of legacy services and the new DOCSIS-based IP video services during the transition. This “Simulcast Roadblock” problem will be described within this paper, and a toolkit of potential solutions will be identified.
