چکیده

This paper points out a phase effect with REDlike queue management algorithms and two-way TCP traffic. It is shown by simulation and measurement that the RED queue converges to a state of heavy oscillation in the presence of two-way bulk-data TCP traffic, causing suboptimal link utilization and service differentiation between in-profile and out-of-profile packets. Besides investigating the reasons for the oscillatory behavior, we show that the oscillations persist in scenarios with two-way Web-like TCP traffic and disappear in case of significant amounts of cross traffic and/or usage of drop-tail instead of RED.

Stability Criteria of RED with TCP Traffic

This report investigates the dynamics of RED queue management in the presence of FTP and Web-like TCP reno flows for scenarios with homogeneous and heterogeneous round trip times. We systematically derive quantitative guidelines and steady state models how to set the RED-parameters as a function of the scenario parameters bottleneck-bandwidth, round-trip-time, number of TCP flows in order to av...

Stability of TCP-RED Congestion Control

We present a method for deriving necessary and sufficient conditions for the local stability of the TCP-RED congestion control. The analysis is based on a differential equation model of the system. One equation describes the dynamics of the TCP source population operating in the congestion avoidance phase. The TCP dynamics are driven by another differential equation representing the RED control...

Linear stability of TCP/RED and a scalable control

We demonstrate that the dynamic behavior of queue and average window is determined predominantly by the stability of TCP/RED, not by AIMD probing nor noise traffic. We develop a general multi-link multi-source model for TCP/RED and derive a local stability condition in the case of a single link with heterogeneous sources. We validate our model with simulations and illustrate the stability regio...
