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.
