Abstract
As additional channels are added to a communication system for applications, such as standard density (SD) and eventually high density (HD) Video on Demand (VOD), additional capacity can be realized by reducing the time required to transmit content. A reduction of transmission time (or an increase of the transmission rate) can be achieved by bonding channels of the communication system. The bonded channels typically provide a statistical multiplexing gain because the additional bandwidth is treated as a large single channel for the download. Bonding channels of the communication system can provide high speed downloading of content, such as video content, far in excess of the playback rate. Using bonded channels can relax the Quality of Service (QoS) requirements of a data stream, such as a video stream, over an internet protocol (IP) network.
