1. What are the ways in which we can keep a check on the number of duplicate packets generated due to the Flooding Routing technique?
Answer: Flooding obviously generates vast numbers of duplicate packets, in fact, an infinite number unless some measures are taken to damp the process. To prevent packets from looping forever, each router decrements a hop count contained in the packet header, whenever the hop count decrement to zero, and the router discards the packet. To reduce looping even further:
1. Add a sequence number to each packet’s header.
2. Each router then needs a list per source router telling …show more content…
For each source router S, a router:
• Keep track of the highest sequence number seen from S.
• Whenever it receives a packet from S containing a sequence number lower than the one stored in its table, it discards the packet.
2. Though Flooding is not a very efficient routing method, it still finds use in a number of applications. Name at least 2 such applications you can think of.
Answer: Flooding is not practical and a very efficient in most applications, but it still has several numbers important uses of applications. For example, in military applications, where large numbers of routers may be blown to bits at any instant, the tremendous robustness of flooding is highly desirable. Based on this reality here is the name of application I may think of this particular perspective:-
1. In military applications, the network must remain robust in the face of (extreme) hostility
2. Sending routing updates, because updates can’t rely on the correctness of a router’s routing table.
3. Theoretical – chooses all possible paths, so it chooses the shortest one.
3. Store and Forward Switches have an advantage over Cut through Switches. What is
