ATM switches based on shared buffering are
known to have better performance and buffer uti­
lization than input or output queued switches. Al­
though shared buffer switches do not suffer from
head of line blocking which is a common problem
in simple input buffering, their performance is ad­
versly affected in the case of unbalanced traffic at
the inputs of the switch. In this paper, we in­
vestigate the performance of a shared buffer ATM
switch in the presence of a hot spot traffic pattern.
In recent years, broadband ISDN (BISDN) has
