Effects of Output Buffer Sharing on Buffer Requirements in an ATDM Packet Switch

Broadband packet switches handling an ATDM-type protocol format can achieve buffer efficiencies by sharing buffers between output ports; the analysis of this paper shows that the number of buffers required with sharing would be over-estimated by as much as 50 percent if the negative correlations that naturally exist between packet streams destined for different output ports were not taken into account.
