8. Relative Differentiated Quality of Service of the Internet
In this chapter, the feedback cyclic control policy is first extended to the case that the arrival rates are not known in advance. The policy is then...

Stabilized Vegas
TCP Vegas was introduced in 1994 [5] as an alternative to TCP Reno. Unlike Reno (or its variants such as NewReno and SACK), that uses packet loss as...

Global Stability of Nonlinear Congestion Control with Time-Delay
In recent years large strides have been taken in analytical approaches to network congestion control. These methods, originating in the academic...
