5) Which of the following statements is true about LAN
Switch and Routers? {Study functional differences and
similarities}
1) What is the 32-bit binary equivalent of 192.122.12.21?
2) Suppose an application generate chunks of 60 bytes of
data every 20 msec, and each chunks get encapsulated in
a TCP segment and then an IP datagram. What percentage
of each datagram will be overhead, what percentage will
be application data?
3) Suppose there are six routers between a source host
and a destination host. Ignoring fragmentation, an IP
datagram sent from the source host to the destination host
will travel over how many interfaces? How many
forwarding tables will be indexed to move the datagram
from the source to the destination?
Solution
a) Binary Equivalent of 192.122.12.21 is
11000000.01111010.00001100 .00010101
b) 40% overhead. IP -- > 40 bytes TCP -- > 40 bytes
The size of application data = 60bytes . Size of a TCP
header = 20 bytes and Size of the IP header is
20 bytes , Thus Total Header size = 40 bytes. Hence
the total segment size is 100 bytes Therefore, percentage
of
