FATHOC — a rate control algorithm for HFC networks
M. M. Macedo, Mario Serafim Nunes, Hermínio Duarte-Ramos · 1998
This paper presents a rate control 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 simplicity, high efficiency, and flexibility to support different classes of traffic. FATHOC (Fairness Achievement Through Congestion) deals with fairness achievement and congestion avoidance problems as a single problem, by trying to achieve fairness dynamically through congestion handling. FATHOC scope of application is both the ABR and nrt-VBR service categories. FATHOC algorithm was designed to work on HFC networks at the Head-end and was developed in the scope of the project ATHOC, a European ACTS research and development project.
