ABSTRACT
Most common network protocols (e.g., the Internet Proto-
col) work with variable size packets, whereas contemporary
switches still operate with fixed size cells, which are easier to
transmit and buffer. This necessitates packet segmentation
and reassembly modules, resulting in significant computa-
tion and communication overhead that might be too costly
