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.

Abstract:

A plurality of secondary stations (10. sub. a through 10. sub. n) are coupled to a primary station (8) by way of a shared communication medium (15, 16). The secondary stations (10. sub. a through 10. sub. n) sends information to the primary channel on the upstream channel. The primary station sending information to the secondary stations (10. sub. a through 10. sub. n) on a downstream channel. The power level of a secondary station (10. sub. n) is set at the power level stored in secondary station memory (55). The secondary station (10. sub. n) transmits a message to the primary station on the upstream channel. The primary station (8) receives the message, determines the power level of the received message, and sets the power level of the secondary device to the nominal power level.
