Spring 2011 Homework 10 1. What is the maximum amount of data that can be carried by a TCP packet that is carried in an IPv4 datagram? Hint: the maximum size of an IPv4 datagram is 65535 bytes, but the datagram must hold the IP header and the TCP header as well as the TCP data. Assume there are no options in the IP or TCP headers. Max TCP data = 65535 – IP header – TCP header = 65535 – 20 – 40 = 65475 bytes 2. The HLEN field in a TCP header is 8. How many bytes are in the header? How many of those bytes are options or padding? Header = 8 x 4 = 32 bytes of header 32-20=12 bytes of options or padding. 3. A sender and receiver use Stop-and-Wait Protocol. Diagram (with arrows going between source and destination) a lost acknowledgement and the recovery. 4. A sender and receiver use Go-Back-N protocol. The sending window size is 4 and the receiving window size is 1. The initial sending window holds packets 0 - 3 and the initial receiving window holds packet 0. The sender sends packets 0 - 3 but packet 2 is lost. Diagram (with arrows going between the source and destination) this situation and the
