Modeled with just simple FTP sessions? Ugh: they admitted to having MIT backbone packet traces to analyze, and then used that simple of a simulator... George William Herbert Sent from my iPhone On Oct 23, 2012, at 8:29 PM, Rodrick Brown <rodrick.brown () gmail com> wrote:
"With coded TCP, blocks of packets are clumped together and then transformed into algebraic equations that describe the packets. If part of the message is lost, the receiver can solve the equation to derive the missing data. The process of solving the equations is simple and linear, meaning it doesn't require much processing on behalf of the router/smartphone/laptop. In testing, the coded TCP resulted in some dramatic improvements. MIT found that campus WiFi (2% packet loss) jumped from 1Mbps to 16Mbps. On a fast-moving train (5% packet loss), the connection speed jumped from 0.5Mbps to 13.5Mbps." http://www.mit.edu/~medard/papers2011/Modeling%20Network%20Coded%20TCP.pdf --RB
