Define the following parameters for a switching network: N = number of hops between two given end systems L = message length in bits B
Define the following parameters for a switching network:
number of hops between two given end systems
message length in bits
data rate, in bits per second bps on all links
fixed packet size, in bits
overhead header bits per packet
call setup time circuit switching or virtual circuit in seconds
propagation delay per hop in seconds
For compute the endtoend delay for circuit switching, virtual circuit packet switching, and datagram packet switching. Assume that there are no acknowledgments. Ignore processing delay at the nodes.
Derive general expressions for the three techniques of part a taken two at a time three expressions in all showing the conditions under which, the delays are equal.
