Abstract
Methods and apparatus for delivering data over extant infrastructure within a content-based network. In one embodiment, the network comprises a cable network, and the infrastructure comprises that nominally used for on-demand (OD) services such as VOD. The method includes the allocation of dedicated end-to-end network resources via a “session request, as well as data flow control and packet size adaptation, by a data server based on feedback from the requesting/receiving client device (e.g., DSTB) within the network. Mechanisms for retransmission requests for error recovery are also provided.
