TCP/IP over ATM based HFC systems

The introduction of fiber to CATV systems can improve noise figures and at the same time expedite the introduction of a return channel to enable support of interactive services. The role of TCP/IP in such services is currently dominant and the efficient support of these widespread protocols is important for cost-effective utilization of the infrastructure. This paper investigates the issues arising from the support of TCP/IP in the peculiar hybrid fiber coax (HFC) environment and proposes solutions for improved performance.
