Improved Utility-Based Congestion Control for Delay-Constrained Communication

Improved Constrained PID Control Design based on Connvex-Concave Optimization

In this paper, an algorithm is proposed to improve the design of constrained PID controller based on convex-concave optimization. This design method is based on the optimization of a performance cost function, taking into account the stability and efficiency constraints with frequency domain analysis in which the concepts of sensitivity and complementary sensitivity has been used. It is shown, ...

Delay-based AIMD congestion control

Our interest in the paper is investigating whether it is feasible to make modifications to the TCP congestion control algorithm to achieve greater decoupling between the performance of TCP and the level of buffer provisioning in the network. In this paper we propose a new family of delay-based congestion control algorithms that we refer to as delay-based AIMD.

The Case for Delay-based Congestion Control

We argue that, in the absence of explicit feedback, delaybased algorithms become the preferred approach for endto-end congestion control as networks scale up in capacity. Their advantage is small at low speed but decisive at high speed. The distinction between packet-level and flow-level problems of the current TCP exposes the difficulty of lossbased algorithms at large congestion windows.

Delay-based Congestion Control for Low Latency

Constrained TCP-Friendly Congestion Control for Multimedia Communication

With the lack of admission control and resource reservation mechanisms in the Internet, overload situations can only be avoided by having the end systems deploying congestion control schemes. That is, the end systems should adjust their transmission and reception behavior in accordance with the available network resources. This is generally achieved by adjusting the transmission behavior of a s...
