A Slotted Medium Access Control Scheme Designed for CATV Network
Résumé
In this paper, we propose for Cable TV Networks (CATV Networks) designs of a slotted medium access scheme with collision detection. These designs are very simple; the used operations are as simple as the ones used in Ethernet. We analyze performance of these medium access schemes and show that easy optimizations of the collision resolution scheme can provide performance close to optimal. We discuss in detail synchronization issues. In the framework of our proposed protocol design,we describe a scheme to handle medium access priority. Our approach allows to handle various applications (ATM, CBR, VBR, ABR) and remains extremely simple.
