Integration of rate and credit schemes for ATM flow control
IEEE Network, 1995The authors make the case in favor of an integrated approach to ATM flow control. They contend that both rate and credit schemes have advantages and disadvantages, and that to a large extent they can be viewed as complementary. >

A Method of Control of a Predetermined Flow Rate
Review of Scientific Instruments, 1953The accurate control and determination of small rates of displacement of fluids are of interest in many experiments. Such problems are of particular importance in nonequilibrium investigations involving diffusion, flow of fluids, and other studies in which time is a primary variable.

The rate mismatch problem in heterogeneous ABR flow control
Proceedings of INFOCOM '97, 2002Because the ATM Forum does not standardize the ABR flow control algorithm that an ATM switch should run, some ATM networks are likely to contain switches that run different ABR flow control algorithms. Even if all the switches within a "cloud" of switches use the same algorithm, individual clouds (each with it own algorithm) will be interconnected by ...

Dynamical behavior of rate-based flow control mechanisms
ACM SIGCOMM Computer Communication Review, 1990Flow control mechanisms are essential for the efficient and stable operation of store-and-forward networks. New transport protocols, such as VMTP and NETBLT, intend to use rate-based flow control. We present a model in which a network with connections subject to rate-based flow control is considered as a dynamical system, i.e., a set of coupled ...

Decentralized optimal flow control with constrained source rates
IEEE Communications Letters, 1999We study optimal flow control in multiservice networks, in which users (controllers) optimize their performance objectives in a decentralized manner. We adopt a model that differs from previously considered ones in that a user's strategy (viz., flow or average rate) is constrained between two numbers: those are specified by the user's quality of ...

Control-theoretic max-min flow control with minimum rate guarantee
GLOBECOM'01. IEEE Global Telecommunications Conference (Cat. No.01CH37270), 2002We present a novel control-theoretic explicit rate (ER) allocation algorithm for the max-min flow control of elastic traffic services with minimum rate guarantee in the context of the ATM ABR service. The proposed ER algorithm is simple in that the number of operations required to compute it at a switch is minimized, scalable in that per-VC (virtual ...

Control of Plug-Flow Tubular Reactors by Variation of Flow Rate
Industrial & Engineering Chemistry Fundamentals, 1970The control of isothermal and adiabatic plug-flow tubular reactors by variation of flow rate was studied. Proportional feedback, feedforward, and optimal control responses were compared for the regulation of reactor conversion in the presence of inlet disturbances.

Convergence Complexity of Optimistic Rate-Based Flow-Control Algorithms
Journal of Algorithms, 1999Summary: This paper studies basic propertics of rate-based flow-control algorithms and of the max-min fairness criteria. For the algorithms we suggest a new approach for their modeling and analysis, which may be considered more ``optimistic'' and realistic than traditional approaches.

The rate-based flow control framework for the available bit rate ATM service
IEEE Network, 1995A new ATM service category, the available bit rate service, is currently the subject of intense development. This new service will systematically and dynamically allocate available bandwidth to users by controlling the flow of traffic with feedback. The rate-based flow control framework has been identified as the most appropriate for the support of ...

Control of flow rate in supercritical fluid chromatography
Chromatographia, 1986Supercritical Fluid Chromatograph was constructed using two pumps and two restrictors. With this system in conjunction with the fused silica column packed with relatively large particles (40 μm), the flow rate was controlled both for isobaric and pressure programmed operations.
