in a virtual network, there are three switches k1, k2 and k3. Source P need to communicate with destination T. The input port, output port and VCI for k1 is 8,4,55, input port, output and VCI for k2 is 6,5,75 and input port,ouport and VCI for k3 is 9,7,66.

Conatruct the packet switch table for k1 k2,k3 and diagramatically represent the flow of setup request and acknowledgement.
