PPT-Precept 2: TCP Congestion Control Review

Q1 The size of the TCP Receive window never changes throughout the duration of the connection TCP Basics Q1 The size of the TCP Receive window never changes throughout the duration of the connection. Advanced Computer Networks: TCP Congestion Control. 1. Principles of Congestion Control. Congestion:. informally: “too many sources sending too much data too fast for the . network. to handle”. different from flow control!. Network Fundamentals. Lecture . 13: Beyond TCP Congestion Control. (a.k.a. how to get a job at MIT). In Between Network and Transport…. 2. Goals:. Replace TCP congestion control. Keep queues/delay short. 3-. 1. Chapter 3.

Background: Congestion Control. What is congestion?. A network state where the arrival rate exceeds the service rate. Throughput starts decreasing (due to packet losses). Delay increases fast (queues build up). (from an OS perspective). Yin Lou. 10/08/2009. Outline. Background. TCP Review. Congestion Avoidance and Control.

We were doing very well, up to the kind of sum when a bath is filling at the rate of so many gallons and two holes are letting the water out, and please to say how long it will take to fill the bath, when my mother put down the socks she was darning and clicked her tongue in impatience..

Absent changes to the network can we actually do something?. Yes. Is there work in the area of measurements that can we do to create “incentives” to make updates in the network happen?.
