What are the trade-offs between circuit switching, packet switching, and virtual circuit switching?
Differentiate, with the help of diagrams, between Packet Switching and Circuit Switching. 1. What are the applications of each kind? 2. What are the advantages and disadvantages of each? 3. Give some application names that use Packet Switching and Circuit Switching.
a) Why can we have the packet header in virtual circuit switching to be much smaller than the typical header in datagram switching? b) Assume that we are using datagram switching (i.e. we are not using virtual circuits). Is it possible to guarantee bandwidth to each source-destination pair? Are there disadvantages of doing this using datagram switching? c) What is the big-O complexity of processing the header of a packet if we are using virtual circuits? Briefly explain why. d)...
Compute the time required for circuit switching and packet switching with the following conditions: •The destination is 4hops away from the source: three intermediate switches between the source and the destination, with 4links. •The distance between source (anddestination) computerto its connected switch is 1Km.The distance between any two adjacent switches is 10Km. •The signal propagation speed is 5x10^5m per second.•The message size is 5 Mega bits (1 Mega = 10^6) •The maximum packet size is 200k bits (1k = 10^3....
Is it possible to use packet switching instead of circuit switching? If yes, explain your answer?
When should a virtual circuit packet network be employed?
help with computer network questions 1. What is the difference between circuit switching and packet switching? 2. What are the different layers in today’s Internet? Why do we create layers? 3. Suppose there is a 10 Mbps microwave link between a geostationary satellite and its base station on Earth. Every minute the satellite takes a digital photo and sends it to the base station. Assume a propagation speed of 2.4 * 10^8 meters/sec. a. What is the propagation delay of...
