We study a traffic measurement issue for active queue management and dynamic bandwidth allocation at a single network node under the constraint of Cell Loss Probability (CLP) or buffer overflow probability. Using the concept of measurement-based Virtual ...

This paper presents results from our measurement and modeling efforts on the large-scale peer-to-peer (p2p) overlay graphs spanned by the PPLive system which is arguably the most popular and largest multimedia streaming p2p system today. We believe that ...

The rapid increase in the volume of unsolicited commercial e-mails, also known as spam, is beginning to take its toll in system administrators, business corporations and end-users. Widely varying estimates of the cost associated with spam are available ...

In this paper we define and evaluate a framework for estimating the energy consumption of Java-based software systems. Our primary objective in devising the framework is to enable an engineer to make informed decisions when adapting a system's architecture, ...

Mobile agents have arisen as an interesting paradigm to build distributed applications, due to the unparalleled advantages they offer. However, along with the advantages they also present new challenges. One of the most relevant is that it is not easy ...

This paper is an experimental follow up to our earlier paper [1] that investigated the TCP simultaneous-send problem which arises in infrastructure mode 802.11 wireless local area networks. In particular it was observed that for file transfer traffic, ...

The Network Processor market is one of the fastest growing segments of the microprocessor industry today. In spite of this increasing market importance, there does not exist a common framework to compare the performance of different Network Processor ...

Taking measure of measurement
The Texas rancher is trying to impress the English farmer with the size of his property. "I can drive out at dawn across my land, and by sundown I still haven't reached my ranch's borders." The Englishman ...

Performance measurements of IEEE 802.11 access points provide important information for networking research and network management. In this paper, we present an active measurement method to determine the maximum saturation throughput of wireless LAN ...

Power grid's traditional security assessment approach - based on SCADA data and off-line studies conducted long in advance of real time operations - are becoming increasingly problematic for real time operations because they cannot fully anticipate all ...

Wireless opportunistic connections are the primary mechanism for transferring data between disconnected nodes, such as vehicles, remote sensors, or village kiosks DieselNet, SeNDT, KioskNet in a delay tolerant network (DTN). Opportunistic connections ...

Information Technology (IT) is playing vital role in today's business success. It has been proved that IT services directly effect on business processes performance and organization success. A main factor, which is directly related to IT performance, ...

Current software-based microarchitecture simulators are many orders of magnitude slower than the hardware they simulate. Hence, most microarchitecture design studies draw their conclusions from drastically truncated benchmark simulations that are often ...

Conventional power estimation techniques are prone to manysources of error. With increasing dominance of coupling capacitances,capacitive coupling potentially contributes significantly toUDSM power consumption. We analyze potential sources of inaccuracyin ...

This paper describes a newly proposed low-power charge-recycling read-only memory (CR-ROM) architecture. The CR-ROM reduces the power consumption in bit lines, word lines, and precharge lines by recycling the previously used charge. In the proposed CR-ROM, ...

Parallel computing is a promising approach that provides more powerful computing capabilities for many scientific research fields to solve new problems. However, to take advantage of such capabilities it is necessary to ensure that the applications are ...

This paper describes a randomized algorithm for approximate counting that preserves the same modest memory requirements of log(log n) bits per counter as the approximate counting algorithm introduced in the seminal paper of R. Morris (1978), and in addition, ...

The combination of unlicensed spectrum, cheap wireless interfaces and the inherent convenience of untethered computing have made 802.11 based networks ubiquitous in the enterprise. Modern universities, corporate campuses and government offices routinely ...

Grid architectures are collections of computational and data storage resources linked by communication channels for shared use. It is important to deploy measurement methods so that Grid applications and architectures can evolve guided by scientific ...
