Show transcribed image text Consider a switching fabric shown in Figure below. Assume that packets 1-..6 are initially in the buffer of input ports at time to as below. . Packet 1 and packet 4 are in buffer at input port 1 in this order . Packet 2 and packet 5 are in buffer at input port 2 in this order . Packet 3 and packet 6 are in buffer at input port 3 in this order The destination output port of each pack is also shown in Figure 1. At each time instance tn (n = 0, 1, 2, ..), starting at time to, a packet from each buffer will be de-queued, switched to an output port, assuming that there is no output port contention. Packets switched at (n =0, 1, 2,?) without output port contention are transmitted from the output port at tn+1. When there is an output port contention, the packet coming from the lower input port number would have the priority and is successfully switched to an output port. For each time instance in the table below, indicate which packets are transmitted from the output ports. Mark ?X? if no packets are transmitted.
