“…For example, the seven sets of finite projective planes are randomly assigned to seven ports. Without loss of generality, port 1 is assigned (1,2,3) and port 2 is assigned (1,4,5), etc. Imagining the switch fabric as a 7 X 7 grid, the locations of switch points of a port on the grid correspond to the points of the set assigned to that port.…”

“…For instance, we want to find the settings of switch points for the path from input port 3 to output port 4. The intersection point of these two sets (1, 6 , 7) and (2, 4,6 ) is ( The state of a switch point of the Crossbar* is very similar to that of a conventional crossbar switch. In the cross state, the signal goes straight through the switch point.…”

“…In the switch below, a cross state refers to a downstream cross state. (4,8,9,15,18) According to the sets, we get the corresponding switch of 16 ports as shown in Figure 6. The decision diagram for the 16 port switch is exactly the same as that of the four port switch.…”

The drawback of a conventional crossbar switch is its high complexity of switch points, O ( N 2 ), where N is the number of ports of the switch. We present an alternative design of crossbar switch (Crossbar*) which maps the locations of the switch points to a set of a finite projective plane. Since the number of points of a set of a finite projective plane is f i , the complexity of switch points is reduced to 0 ( N J N ) . We also show a simple self routing algorithm, which is essential for fast cell switching. An analytical performance evaluation for bursty traffic based on Markov Modulated Poisson Process Model (MMPP) demonstrates that the cell loss probability is about ten percent higher than that of the conventional crossbar switches due to blocking effect of the Crossbar*. 0-7803-3873-1/97 $1 0.00 0 1997 IEEE 1 84
