Monday, June 26th: TCP 1

• Jamshid Mahdavi, Shawn Ostermann
• Room 116

8:00 am - 9:00 am	Breakfast
9:00 am - 10:00 am	Introduction to TCP - Internet Protocol Stack/Layers - End to end argument - Duties of the Transport Layer Reliability Connection Establishment Mux/demux Congestion control - TCP Packet Format - TCP state machine
10:00 am - 10:30 am	Introduction to Analysis of TCP Packet Traces - Lab Tools Netperf application tcpdump: packet traces tcptrace: analyze traces xplot: plot traces
10:30 am - 11:00 am	Break
11:00 am - 12:00 pm	TCP loss and congestion control - Loss detection Timers RTO calculation - Flow control - Congestion control (Slowstart, Cong Avoidance) - Fast retransmit/Fast Recovery
12:00 pm - 1:00 pm	Lunch
1:00 pm - 2:30 pm	Lab 1 - This lab will consist of about 5-7 different packet traces of TCP connections. - Students will analyze each trace. 1. Find the RTT for the connection. 2. Find the average bandwidth achieved. 3. Estimate the available bandwidth. 4. Attempt to identify TCP problems in the connection.
2:30 pm - 4:00 pm	Extensions to TCP - Introduce new concepts to fix problems seen in Lab I. Reno problems ==> SACK, NewReno 16 bit Window ==> WinScale Timers ==> Timestamp option (but not good?) Packet sizes ==> Path MTU Packet Loss ==> ECN also RFC2414 larger initial window - We will demonstrate each with traces as well.
