Questions from the topic - 5. Transport Layer (5 hours) - Computer Networks
  1. Why do you think that there exists two protocols in transport layer where as there exists only one in Internet layer in TCP/IP reference model. Explain token bucket algorithm for congestion control. - 2069 Chaitra
  2. What are the differences between TCP and UDP services? Explain the TCP datagram format in detail. - 2068 Chaitra

    b) Secret Key Algorithm: DES
    c) ISDN Signalling and ATM AAl
    d) ICMP Message Types - 2066 Bhadra
  5. Both UDP and TCP use port numbers to identify the destination entity when delivering a message. Give two reasons for why these protocols invented a new abstract ID (port numbers), instead of using process IDs, which already existed when these protocols were designed. - 2065 Shrawan
