Answer 1

The ICMP is an error reporting protocol nad it is having the devices like routers and that is helpful to generate the error messages to the respective source ip address whenever the network problems that are preventing the delivery of the IP packets.

The ICMP is not a transport protocol but it sends to the data between systems There are several types of ICMP types are there those are sent by the host or the gateway.These all can explains about the error condition. The main types of this ICMP types are ECHO_REQUEST.

1.The ICMP ECHO_REQUEST is the type 8 and the Echo reply type 0 because the ICMP uses this messages in the tandem.

2.The remote hosts uses these two messages to the type to the test connectivity .

3.Whenver the user executes the ping command utility and starts the process of the intializing the generation of the ICMP ECHO_REQUESTS it is having some expectation that the destination host sebds a corresponding ECHO_REPLAY.

4.When we get the successful recipt of the replies to the echo requests the followinf messages are comes to follows.

• firstly it indicates the successful test of the program.
• It follows the valid communication between the paths which that has been exist.
• We need to assume that the end hosts that may be work only on the network laayer.

The ECHO_REQUEST and the replay that is generated when we use the ping utility tool.
