ABSTRACT
In this paper we present a concept of new architectural model consisting of multiple loop delay to increase
the throughput. The simulated behavior of an optical node has been realized by using an n x m optical switch
and recirculating optical delay lines. This investigation infers the scaling behaviors of the proposed architec-
ture to maintain efficient use of the buffer under Poisson traffic loading. The analysis also reports the traffic
handling capacity for the plexity of the node architectural design.
