Global Stability Analysis of a Nonlinear Model of Internet Congestion Control With Delay
Matthew M. Peet, Sanjay Lall · IEEE Transactions on Automatic Control · 2007
We address global stability of a model for the TCP/AQM congestion control protocol. This model represents the dynamics of a single link and single source, and consists of a nonlinear differential equation with a time-delay. We make use of absolute stability theory and integral-quadratic constraints to give conditions under which the dynamics are globally asymptotically stable
