Question:
(a) Explain the usage of the following parts of the IPv4 datagram format.
i. VERS ii. HLEN iii. TOTAL LENGTH iv. SERVICE TYPE v. HEADER CHECKSUM
(b) Name the fields present in IPv4 no longer present in IPv6. Why are these fields no longer required?
(c) The deployment of IPv6 has been slow to date. Why has it been slow? What is needed to accelerate its deployment?
(d) Consider sending a 5000-byte datagram into a link that has a MTU of 1500 bytes. Suppose the original datagram is stamped with the identification number 256. How many fragments are generated? What are their characteristics?
(e) A client requesting an IPv4 address will broadcast messages on the physical subnet to discover available DHCP servers. Will the client send a TCP or UDP packet? To which destination IP address will this packet be addressed?
Virtual channel is normally a link from one source to one destination, although multicast connections are also allowed. The other name for virtual channel is virtual circuit.
Factor Causing Parallel Overheads Figure clearly explains that the performance metrics are not able to achieve a linear curve in comparison to the enhance in number of process
Q. Describe Physical Layer in OSI layers model? Physical Layer : Controls the transmission of the actual data onto the network. It describes the electrical signals, line state
What metrics are used by routing protocols to verify the best path?
In this part we shall give a short description of the routines in the PVM 3 user library. Each PVM program should include the PVM header file "pvm3.h" (in a C program) or "fpvm3.h"
UDP is connectionless, and does not give error checking. But remember, error checking can happen at other layers too.
In this project, you will implement a Transport Layer protocol to transmit data with Reliable Data Transfer from a client to a server in the presence of channel errors and loss. Th
What is horizontal and vertical parity A single error can cause both horizontal and vertical parity checks to be wrong. Two errors can also be easily detected. If they are not
How can I identify the difference types of networks
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
