Time to Live (TTL) field: This field records the number of hops the datagram may make before being destroyed. A hop is the name given to the action of passing over a data link between contiguous nodes. Each node handling the datagram reduces the TTL number by one. When TTL reaches zero, unless the node handling it is the destination, the datagram is destroyed. If the datagram is a broadcast message, TTL is set to 1 by the source. In this way, the datagram is restricted to the immediate network and is not forwarded.
Finally, to avoid confusion, it is as well to repeat that IP forms datagrams. If UDP is employed as the transport layer protocol, the frame is forwarded through TLFeBOOK 26 A TCP/IP World? 10 IP ARP/InvARP Data link sublayer Physical sublayer IP Internet protocol ICMP Internet control message protocol IGMPInternet group management protocol ARP Address resolution protocol InvARP Inverse address resolution protocol TCP/IP protocol stack. the network on a best-effort basis without path control, no connection is established, acknowledgments are not given, and error and flow control are not used.
13. CP-B sends a Ready to Receive message to CP-A. 14. CP-A notifies the operator that the connection is ready. 15. The operator logs on to Host B with a password and sends the request: Get yyyy. The request may include the size of the buffer allocated to receive yyyy and the maximum speed at which it can be received. 16. CP-B consults a list of valid users, or by other means determines that it may respond to the request. 17. CP-B requests File yyyy from its operating system (OS-B). 18. OS-B transfers a copy of the file to the control of CP-B.
