Dynamic bandwidth allocation in broadband-ISDN using a multileveloptimal control approach
(1995)This paper presents a novel scheme for the dynamic allocation of bandwidth at the virtual path level in B-ISDNs. A fluid flow model is developed to describe the time varying mean behaviour of a virtual path and serves as ...

A multilevel optimal control approach to dynamic bandwidth allocation in broadband ISDN
(1995)In this paper a novel scheme for the dynamic allocation of bandwidth at the virtual path level in B-ISDNs is presented. A fluid flow model is developed to describe the time varying mean behaviour of a virtual path and ...

Aggregated bandwidth allocation: Investigation of performance of classical constrained and genetic algorithm based optimisation techniques
(2002)We consider a high speed integrated services network, and investigate compare and contrast the performance of two algorithms for solving the Aggregated Bandwidth Allocation (BA) problem. The algorithms we focus our attention ...

Bandwidth Allocation for Virtual Paths (BAVP): Investigation of performance of classical constrained and genetic algorithm based optimization techniques
(2000)We investigate the performance of a classical constrained optimization (CCO) algorithm and a constrained optimization Genetic Algorithm (GA) for solving the Bandwidth Allocation for Virtual Paths (BAVP) problem. We compare ...

Adaptive nonlinear congestion controller for a differentiated-services framework
(2005)The growing demand of computer usage requires efficient ways of managing network traffic in order to avoid or at least limit the level of congestion in cases where increases in bandwidth are not desirable or possible. In ...

Congestion control for differentiated-services using non-linear control theory
(2001)The growing demand of computer usage requires efficient ways of managing network traffic in order to avoid or at least limit the level of congestion in cases where increases in bandwidth are not desirable or possible. Using ...

Integrated control of connection admission, flow rate, and bandwidth for ATM based networks
(1996)We consider the combined control problem of connection admission, flow rate, and bandwidth allocation (capacity, service-rate) under nonstationary conditions. A fluid flow model in state variable form describes the time ...

Integrated switching strategy for ABR traffic control in ATM networks
(1997)In this paper we extend earlier results on combined control problem of connection admission, flow rate, and bandwidth allocation (capacity, service-rate) in ATM based networks under nonstationary conditions to the multiple ...

MBMS Handover control: A new approach for efficient handover in MBMS enabled 3G cellular networks
(2007)With the introduction of Multimedia Broadcast Multicast Service (MBMS) system in 3rd Generation (3G) mobile cellular networks, the Radio Network Controller (RNC) for radio resource efficiency can use either Point-to-Point ...

Locating objects in mobile computing
(2001)In current distributed systems, the notion of mobility is emerging in many forms and applications. Mobility arises naturally in wireless computing since the location of users changes as they move. Besides mobility in ...

Social confluence in client-server systems
(1997)An extension to the theory of partial confluence of concurrent systems is presented in the setting of the polyadic π-calculus. The main result, expressed in terms of client-server systems, is that in certain client contexts, ...

Article
On sharing and determinacy in concurrent systems
(1995)The relationship between sharing and determinacy in concurrent systems is studied. Syntactic conditions on programs of a concurrent object language are isolated and it is established, on the basis of two different semantic ...

Article
On transformations of concurrent object programs
(1996)Transformation rules which increase the scope for concurrent activity within systems prescribed by programs of concurrent object languages are given. The correctness of the rules is proved using a semantic definition by ...

On confluence in the π-caleulus
(1997)An account of the basic theory of confluence in the 7r-calculus is presented, techniques for showing confluence of mobile systems are given, and the utility of some of the theory presented is illustrated via an analysis ...

DBGlobe: A service-oriented P2P system for global computing
(2003)The challenge of peer-to-peer computing goes beyond simple file sharing. In the DBGlobe project, we view the multitude of peers carrying data and services as a super-database. Our goal is to develop a data management system ...
