Rate based congestion control promises effective traffic management for ABR service class suitable to data communications in ATM networks. The rate based congestion control algorithm dynamically regulates transmission rate of source end system according to feedback information from the network. In this paper, we described two rate based congestion control algorithms, Explicit Forward Congestion...

Modern persistent Key/Value stores are designed to meet the demand for high transactional throughput and high data-ingestion rates. Still, they rely on backwards-compatible storage stack and abstractions to ease space management, foster seamless proliferation and system integration. Their dependence on the traditional I/O stack has negative impact on performance, causes unacceptably high write-...

The performance evaluation of the regional innovation system (RIS) based on the management entropy theory can dynamically describe its overall innovation level and its development trend. This article describes the content of management entropy theory and analyzes its function mechanism of the RIS. On the basis of above, this article establishes its own index evaluation system and entropy evalua...

For many emerging applications and environments , information systems designers and im-plementors must consider the tradeoos between eeciency and the quality of query answers. This exibility, while allowing numerous opportunities for optimization, complicates the development of various system components and their performance evaluation. In this short paper, we begin by outlining issues that ari...

The elements of modelling in general and of performance evaluation of discrete event systems (DES) in particular have undergone a tremendous transformation during these last four decades. The aim of this paper is to look back over all this evolution, trying to retain some particular experiences from the past. I will try to classify these elements according to what I have perceived as their posi...

The INET framework for the simulation tool OMNeT++ provides a TCP module, which can be used for evaluating various Internet applications. However, the implementation of this TCP module has not been state of the art. Some important features of modern TCP implementations – particularly Selective Acknowledgements (SACK) and a complete Flow Control – have been missing. In this paper, we first intro...

A survey of four research papers pertaining to performance evaluation of operating system is presented. This survey and its related discussion highlight the approaches to system evaluation along with its associated challenges and tradeoffs. The article speaks to methodological issues of realism, accuracy, the granularity of measurement, the portability of measurement techniques and tools, as we...
