Abstract :
The design of a dynamic MAC protocol to arbitrate the common medium in a hybrid fiber coaxial system providing service differentiation and enhanced QoS capabilities as well as the implementation, testing and verification of the MAC controller are described in this paper. The MAC protocol employs four access priorities and a flexible reservation scheme. The MAC controller was implemented mainly in hardware to execute all real-time operations and was integrated in the AROMA HFC system, which is shown. Various group tests were carried out using the lab demonstrator of the system to assess the system performance and verify that the developed implementation meets the design objectives concerning QoS differentiation
