Question
Consider the above figure, in which there is a cloud ofnetworks having various networks.
Suppose there are 7 routers in betweenHost A and Host B.
Identify
a. How come host A knows theaddresses of all the routersbetween A to B?
b. What will be the value of the TTLfield when the source host A sends thedatagram 7th
time towards the destinationB, and the third router in thepath receives that datagram?
c. How many times does the source Aneeds to send the datagram so that it finally reaches at
destination host B?
d. What will be the value of the TTLfield when the source host A sends thedatagram 4th
time towards the destinationB, and the second router in thepath receives that datagram?
e. What will be the value of the TTLfield when the source host A sends thedatagram first
time towards the destinationB, and the first router in thepath receives that datagram?
Explanation / Answer
Dear, a. The address of all the routers inbetweenHost A and Host B can be obtained by using the information in the"Routing Table" b. Here the Time To Live( TTL ) valuewill be 4 c. Until Unless the value of the TTL becomes 0,Host A sends datagrams to Host B. d. Here the TTL value will be 5 d. Here the TTL value will be 5 e. When Host A first time sends the datagram thevalue of TTL field will be 7. " I hop this willhelp you " " I hop this willhelp you "Related Questions
