a) Assume that the time required to transmit one packet (i.e. the packet length divided by link data rate) is 10ms and the Round Trip Time (from Source to Destination and back) is 50ms. In the space below, draw a diagram illustrating the timing of Source and Destination exchanging packets and acknowledgments using a stop-and-wait protocol. Assume that packets are only sent from source to destination and that acknowledgments (of negligibly small size) are sent back immediately after the data frame is received.
b) Calculate link utilisation (proportion of time the channel is actually used for transmission) for the stop-and-wait case.
Q Illustrate Return to Zero encoding? - In NRZ-I long strings of 0s may still be a problem - May comprise synchronization as part of the signal for both 1s and 0s - How?
Ans) The Transport Layer : Segments upper-layer applications. Establishes an end-to-end connection. Sends segments from one end host to another. Optionally, make sures
CHARACTERIZATION OF NETWORKS: There are three kinds of characterization of networks. LOCAL AREA NETWORK (LAN): It is needed for a single building. METROPOLOTAN AREA
These are fully-loaded machines which consists of multiprocessors, high-speed disk arrays for interview I/O and fault tolerant features.
Address is a full unique identifier. Connectionless delivery needs address on every packet. Connection-oriented delivery may use a short hand that shows the connection rather th
