This work proposes a fluid model for a large class of MP-TCP algorithms and identifies design criteria that guarantee the existence, uniqueness, and stability of system equilibrium and motivates the algorithm Balia (balanced linked adaptation), which generalizes existing algorithms and strikes a good balance among TCP-friendliness, responsiveness, and window oscillation.

- 1 August 1995
A new approach to determining the admissibility of variable bit rate (VBR) traffic in buffered digital networks is developed, and the boundary of the set of admissible traffic sources is found to be sufficiently linear that an effective bandwidth can be meaningfully assigned to each VBR source.

- 14 March 2010
This paper develops light-weight cooperative cache management algorithms aimed at maximizing the traffic volume served from cache and minimizing the bandwidth cost, and establishes that the performance of the proposed algorithms is guaranteed to be within a constant factor from the globally optimal performance.

An approximation to the steady-state buffer distribution is called Chenoff-dominant eigenvalue, which is effective for analyzing ATM multiplexers, even when the traffic has many, possibly heterogeneous, sources and their models are of high dimension.
Analysis, approximations and admission control of a multi-service multiplexing system with priorities

- Computer ScienceProceedings of INFOCOM'95
- 2 April 1995
An ATM system with an architecture which is designed to accommodate users with very different quality of service requirements is considered and a characterization of the output of the high priority buffer as another Markov-modulated fluid source is characterization.

Analysis of separable Markov-modulated rate models for information-handling systems
- T. Stern, A. Elwalid
- Computer ScienceAdvances in Applied Probability
- 1 March 1991
In this work a general mathematical model for separable MMRPs is presented, focusing on Markov-modulated continuous flow models, and it is shown that the ‘state explosion' problem typical of systems composed of a large number of subsystems can be circumvented because of the separability property.
