FATHOC- a rate control algorithm for HFC networks

摘要

This paper presetns a rate contorl algorithm to use with SARP (Simple ATM based Reservation Protocol) for HFC (Hybrid Fibre Coax) networks.The SARP is a hybrid reservation and rate based protocol.,based on ATM,whose main characteristics are its wsimplicity,high efficiency,and flexibility to support different classes of traffic.FATHOC (Fairness Achievement Through Congestion) deals with fairness achievement and congestion avoidance probems as a single problem,by trying to achieve fairness dynamically through congestion handling.FATHOC scope of applcation is both the ABR and nrt-VBR service categories.FATHOC algorithm was designed to work on HFC netowrks at the Head-end and was developed in the scope of the project ATHOC,a European ACTS research and development project.
