Chapter 7, Problem P14P
Explanation of Solution
Chaining used in direct routing:
As in the section 7.7.2, suppose the chaining is used in indirect routing via home agent, the following events would occur:
- The node “A” will get the mobile node then “A” alerts the home agent that the mobile node currently visiting “A”. The datagram to the mobile is forwarded to the particular COA (care-of-address).
- The mobile node is moved to the node “B”. The foreign agent at node “B” will alerts the foreign agent at node “A” and in node “A” the mobile node is no longer stayed, but in fact is resident in node “B” and that has the specified care-of-address in node “B”. Forward the datagrams by the foreign agent in node “A” and it receives that are addressed to the mobile care-of-address in node “A” to the mobile care-of-address in node “B”.
- The mobile node is moved to the node “C”. The foreign agent at node “C” will alerts the foreign agent at node “B” and in node “b” the mobile node is no longer stayed, but in fact is resident in node “C” and that has the specified care-of-address in node “C”. Forward the datagrams by the foreign agent in node “B” and it receives that are addressed to the mobile care-of-address in node “B” to the mobile care-of-address in node “C”.
If the mobile node returns to the home agent or it goes offline, the datagram forwarding state must be maintained by the foreign agents in “A”, “B” and “C” are removed.
Chaining not used in direct routing:
Suppose the chaining is not used in indirect routing via home agent, the following events would occur:
- The node “A” will get the mobile node then “A” alerts the home agent that the mobile node currently visiting “A”...

Goal: Understand how to build a concurrent server and deal with signals Description:
Use TCP socket programming in C to implement a pair of client and server programs. The
client simply asks the user to enter a string (null-terminated), and then displays a menu for the user to
select an operation on that string. The string and the type of operation are sent to the child server which
performs the required operation and returns the result back to the client. That is, the server (parent)
creates a child for each request of the client (you need to print the port and IP address of the client on
the server terminal). Then it waits for the child to finish processing client's request and prints the
process ID of the terminated child.
The connection between your client and server should stay open, so that the client can send another
request. However, the exit will happen when the user sends the client program the SIGQUIT signal.
The handler will print a notifying message (for example, "Good…
