Abstract
An apparatus, method and system for delivering Internet Protocol (IP) content within a system that includes a bypass architecture, using a Session Encapsulation Information Database (SEIDB). Within an existing PacketCable Multimedia (PCMM) framework used as a control plane for IP content bypass flow setup, the SEIDB system stores session bypass encapsulation information for IP content bypass flows within the system. Within the SEIDB, each entry of bypass encapsulation information has a flow classifier component that uniquely identifies a bypass flow in a manner that allows both a cable modem termination system (CMTS) and the IP content source to uniquely identify the bypass flow at the SEIDB. Initially, the CMTS gathers bypass encapsulation information and uploads it to the SEIDB. Before the bypass flow begins, the IP content source obtains the necessary bypass encapsulation information from the SEIDB, e.g., using a flow classifier as a search filter item.
