DQDB — Some New Characteristics
Lars Falk, Ulf Körner · 1995
In this paper we study the DQDB bus under heavy traffic conditions. We also observe the impact of bursty traffic on the access delay. Here we especially study the impact of the third moment in the arrival process and find that the access delay decreases dramatically with an increase of the skewness, when lower arrival moments are kept constant. In fact for constant first and second moments we can obtain almost any value of the access delay by varying the third moment. Under heavy traffic conditions we found that the “normal” DQDB-unfairness is reversed. Some variants of DQDB are introduced in order to decrease the unfairness. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
