A. Shibata et al., METHODS FOR STORING ARRIVING CELLS IN A SHARED MULTI-BUFFER ATM SWITCH, Electronics & communications in Japan. Part 1, Communications, 82(2), 1999, pp. 39-47
A shared multi-buffer ATM switch is cost-effective, since it uses low-
access-speed memories when compared with a shared single-buffer ATM sw
itch. Due to the low access speed, however, the switch cannot read sev
eral cells from a buffer during a single access. Such an access confli
ct provides a high cell loss rate. In this paper, we propose several c
ell storage methods that avoid the access conflict, and we compare our
approach via simulation with the previously proposed cost-ineffective
solution that uses high speed memories under various load conditions.
The results show that one of the proposed methods in this paper provi
des an almost equivalent cell loss characteristic to the previously pr
oposed approach. (C) 1998 Scripta Technica, Electron Comm Jpn Pt 1, 82
