Title: A probabilistic analysis of traffic separation in shared Ethernet systems using the h-BEB collision resolution algorithm
Issue Date: 2005
Abstract: Ethernet is a widely used network technology, with a Medium Access Controlprotocol based on the collision detection between randomly initiated transmissions.It has a non-deterministic behaviour, due to the use of a probabilistic contentionresolution algorithm, which impairs the support of real-time communications. In thispaper, it is proposed the use of a modified algorithm for the collision resolution inshared Ethernet networks. Such algorithm, referred as high priority BinaryExponential Backoff (h-BEB), provides high priority traffic separation, enabling thesupport of real-time communications. It allows multiple Ethernet standard devicesto coexist with one h-BEB modified station in the same network segment, imposing ahigher priority for the transfer of h-BEB related traffic. The probabilistic analysis oftraffic separation provided by the proposed algorithm shows that it guarantees anaccess delay significantly smaller for an h-BEB station, when compared with theaccess delay for BEB stations.
