Abstract (EN): In this paper, it is presented the simulation analysis of an enhanced algorithm for the collision resolution in shared Ethernet networks. Such algorithm, referred as high priority Binary Exponential Backoff (h-BEB), provides high priority traffic separation, enabling the Support of real-time communications. One of the main features of the h-BEB algorithm is to enable the coexistence in the same network segment of Ethernet standard stations with h-BEB modified stations, by imposing higher priority for the transfer of h-BEB messages (privileged traffic). The simulation analysis shows that the proposed traffic separation guarantees a predictable and significantly smaller access delay for the h-BEB station, when compared with the access delay for standard Ethernet stations. The simulation analysis also shows that the h-BEB traffic must be tightly controlled, as it has a high interference level over the non-real-time traffic. Otherwise, if the load generated by the h-BEB station is not closely controlled, the standard Ethernet stations may experience extended access delays.
