Slot-reuse in high-speed communication networks

摘要

In this paper we discuss the possible gain of bandwidth for slot-reuse mechanisms in high-speed networks, depending on the traffic matrix and topology. For this investigation an analytical approach is used to calculate the optimal location of a given number of so-called erasure nodes for a fixed traffic matrix. The influence of changing traffic matrices on the gain of bandwidth is also considered. Furthermore we show the effect of dominant stations on the optimal location of erasure nodes. Finally we discuss the problems of implementing erasure nodes in an DQDB network.
