1. Assume a private internet uses a protocol suite totally different from the TCP/ IP protocol suite. Can this internet still use the services of UDP or TCP as an end-to-end vehicle of message communication?
2. Can you explain why we need four (or sometimes three) segments for connection termination in TCP?
3. In TCP, some segment types can be used only for control; they cannot be used to carry data at the same time. Can you define some of these segments?
