Preprocessing DNS Log Data for Effective Data Mining

The Domain Name Service DNS provides a critical function in directing Internet traffic. Defending DNS servers from bandwidth attacks is assisted by the ability to effectively mine DNS log data for statistical patterns. Processing DNS log data can be classified as a data-intensive problem, and as such presents challenges unique...

Characterizing the SPEC JVM98 Benchmarks on the Java Virtual Machine

This paper presents the results of a characterization analysis performed on the Java Virtual Machine JVM using the SPEC JVM98 benchmarks. An instrument is developed that runs inside the JVM that provides profiles of a variety of different workload characteristics. The data from these profiles are examined to better understand...

Localized Message Passing Structure for High Speed Ethernet Packet Switching

This paper introduces two different physical structures and topologies to realize an ethernet layer-2 switch. To evaluate these two structures and produce throughput projections the paper has utilized MPI. This simulation environment has helped to identify performance bottlenecks and to give an overall estimation of the switch throughput. The results...

Dynamic Input Buffer Allocation (DIBA) for Fault Tolerant Ethernet Packet Switching

This paper describes a new fault-tolerant architecture to realize an Ethernet layer-2 switch. This architecture includes a memory buffer scheduler to assign memory buffers dynamically to the input ports of the switch. To evaluate this architecture and produce throughput and latency projections, the paper has developed a switch simulator called...

Nanodisks used to encrypt information

PhysOrg.com reports that U.S. researchers have used nanotechnology tricks to develop nanodisks which could be useful to create codes to encrypt information. This method, which conceptually is similar to barcodes, could be used for DNA tagging or tracking goods and people. Even if this looks interesting, the best part is...

On the Performance of IEEE 802.11 Under Jamming

This paper studies the performance of the IEEE 802.11 MAC protocol under a range of jammers that covers both channel-oblivious and channel-aware jamming. The paper studies two channel-oblivious jammers: a periodic jammer that jams deterministically at a specified rate, and a memoryless jammer whose signals arrive according to a Poisson...

Information Systems Risk Factors, Risk Assessments, and Audit Planning Decisions

This paper examines systems risk factors identified by external auditors for a sample of their actual audit clients. Specifically, the paper studies two important areas of information systems risk: the risk of breaches in system security and the risk that the information provided by the system is inadequate. To perform...

Improving Throughput Performance of the IEEE 802.11 MAC Layer Using Congestion Control Methods

This paper presents and analyzes adaptive fragmentation algorithms for enhancing throughput performance under a slow fading channel. It first studies the similarities between the TCP protocol and MAC protocol. Next, it proposes an adaptive approach to change the fragmentation size dynamically according to variations of the wireless channel quality. Simulation...

Mobility Models for Ad Hoc Network Simulation

This paper proposes a novel general technique, based on renewal theory, for analyzing mobility models in ad hoc networks. The technique enables an accurate derivation of the steady state distribution functions for node movement parameters such as distance and speed. The paper first applies the technique to the random waypoint...
