Appl. No.:

10/032100

Gerald Grand - Cumming GA, US
Niki R Pantelias - Duluth GA, US
R. Jeff Lee - Lawrenceville GA, US

Francisco J Gomez - Lawrenceville GA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H04L 12/56

US Classification:

370389, 370466

Abstract:

A method and system for creating an ethernet-formatted packet from an upstream DOCSIS packet. The upstream packet is first received along with packet characteristic data that is contained in physical layer prepend data and in the packet header. A packet tag is then created, based on the packet characteristic data. The packet characteristic data includes identifiers for the transmitting remote device and the channel over which the transmission is sent. Packet characteristic data also includes information about the physical characteristics of the transmission signal, such as the power level and time offset. The packet characteristic data also includes administrative information, such as the minislot count at which the packet is received and whether the packet was received in contention. The packet tag is appended to the payload of the upstream packet. Also appended to the payload is an encapsulation tag, and source and destination address headers.
