1) For the bit stream 01100011101, sketch the waveforms for Miller encoding techniques.

2) Define the following parameters for a switching network:

N = number of hops between two given end systems

L = Message length in bits

B = data rate, in bits per second (bps), on all links

P = fixed packet size, in bits

H = overhead (header) bits per packet

S = call setup time in seconds

D = propagation delay per hop in seconds

For N = 10, L = 12800, B = 56000, P = 1024, H = 32, S = 0.2, D = 0.001, compute the end-to end delay for circuit switching, virtual circuit packet switching, and datagram packet switching. Assume that there are no acknowledgments. Ignore processing delay at the nodes.

Circuit Switching: 0.438 ms.

Datagram Packet Switching = 245 ms.

Virtual Circuit Packet Switching: = 445ms

3) What is the percentage of overhead in a T1 carrier? (Overheadany information on a frame that is not part of actual data)

Voice T1 career the overhead is 12.95%

Data T1 career the overhead is 16.58%

I need to confim my answers are correct. Apparently my virtual and datagram are off but i would like to get a second opinion
