Active queue management with discrete sliding modes in TCP networks

Active queue management with discrete sliding modes in TCP networks

Abstract. In this paper, a new active queue management (AQM) algorithm for data traffic control in TCP/IP networks is developed. The algorithm design is based on the principles of discrete sliding-mode control. Unlike majority of earlier studies, the design procedure considers the effects of both non-negligible delay in transferring data and feedback information and unpredictable capacity varia...

Synthesis of Robust Active Queue Management controllers in TCP Networks

This paper is concerned with the derivation of improved AQM control schemes to cope with unwanted variations of characteristic parameters such as the the average round-trip time, the load and the link capacity. To achieve this aim, we use novel robust control strategies for time-delay systems, which are based on the use of robust reduction methods and H∞ strategies resulting in memory and memor...

Modelling BLUE Active Queue Management using Discrete-time Queue

This paper proposes a new discrete-time queue analytical model based on BLUE algorithm in order to determine the network congestion in preliminary stages. We compare the original BLUE, which has been implemented in Java, with our proposed analytical model with regards to different performance measures (average queue length, throughput, average queueing delay and packet loss probability). The co...

TCP Enhancement: Fast Active Queue Management Scalable Transmission Control Protocol

FAST TCP is Fast Active queue management Scalable Transmission Control Protocol. FAST TCP is an alternative congestion control algorithm in TCP. It is designed for high speed data transfers over large distance. FAST TCP is assumed to be the “successor” of TCP. Lot of people already worked on this subject. Their research work and results yield a new dimension for the entertainment and scientist ...
