What are the main problems a transport protocol must solve to achieve reliable transfer?
What will be an ideal response?
An end-to-end transport protocol must be carefully designed to achieve efficient, reliable
transfer. The major problems are:
? Unreliable Communication. Messages sent across the Internet can be lost, duplicated,
corrupted, delayed, or delivered out of order.
? End System Reboot. At any time during communication, either of the two end systems might
crash and reboot.
? Heterogeneous End Systems. A powerful sender can generate data so fast that it overruns a
slow receiver.
? Congestion In The Internet. If senders aggressively transmit data, intermediate switches and
routers can become overrun with packets, analogous to a congested highway.
