A queuing model with discrete service speeds
ACM SIGSIM Simulation Digest, 1976An input source of the model is generated in accordance with a probability density function P r (n,t), where n and t are a spatial variable and a time variable, respectively. Thus the input arrives as a time-variable train.

Queues with service speed adaptations
Statistica Neerlandica, 2008In this paper, we consider various queueing models in which the server can work at two different service speeds. The speed of the server depends on either the number of customers or the workload. Our main interest is in the model in which service speed adaptations can take place only at the arrival instants of an external Poisson observer.

DANTE's plans for high speed services
Computer Networks and ISDN Systems, 1994Abstract DANTE has been formed as a non-profit company by a group of national research networks in order to provide them with international services. In addition to the 2◊Mbps multi-protocol service which it already operates, DANTE is making plans to introduce 34 Mbps and higher speed services as soon as this is feasible.

Responsive aperiodic services in high-speed networks
[1993] Proceedings. The 13th International Conference on Distributed Computing Systems, 2002A fast packet-switched network is considered that transmits fixed-sized packets or cells and provides connection-oriented services. A number of rate-based service disciplines that offer timing guarantees have recently been proposed. These disciplines work well for connections which exhibit low burstiness or whose burstiness can be managed by admission ...

Adaptive transport service for high speed networks
Concurrency: Practice and Experience, 1994AbstractIt has been shown that protocol processing represents a severe bottle‐neck for high speed computer networks. The disadvantages of currently proposed solutions are their incompatibility with existing standardised protocol implementations, their complexity and/or their inflexibility.

The backlog process in queues with random service speed
International Journal of Systems Science, 1996This paper examines the backlog (total amount of unfinished work in the system) in a single server queue that works in a ‘random environment’. Specifically, the service speed is described by an exogenous (non-negative) ‘environment’ process. We characterize the time-dependent backlog via a stochastic integral equation and use this equation to compute ...

Access Protocols for Cellular High-Speed Data Services
International Journal of Wireless Information Networks, 1999In this contribution, novel access techniquesfor the future cellular information networks areproposed. To facilitate a fast deployment, the suggestedaccess techniques have been implemented over well-known technological platforms, namely DECT (DigitalEnhanced Cordless Telecommunications) containing aFDM/TDMA (Frequency Division Multiplex/Time ...

Loading Speed of Modern Websites and Reliability of Online Speed Test Services
2015Loading speed of websites reflects the website´s performance and has a significant influence on user experience and satisfaction. In this paper we analyze causes and consequences of slow loading of websites, followed by recommendations and comments on usual practice and feasibility.

cISP: A Speed-of-Light Internet Service Provider.
2022Low latency is a requirement for a variety of interactive network applications. The Internet, however, is not optimized for latency. We thus explore the design of wide-area networks that move data at nearly the speed of light in vacuum. Our cISP design augments the Internet's fiber with free-space microwave wireless connectivity over paths very close ...

Queues with adaptable service speed
Statistica Neerlandica, 2008In this paper, we consider various queueing models in which the server can work at two different service speeds. The speed of the server depends on either the number of customers or the workload. Our main interest is in the model in which service speed adaptations can take place only at the arrival instants of an external Poisson observer.
