Networked computer systems are no different. The notion of privacy is running squarely against the need for security in an increasingly networked world. Is it possible to have secure systems that honor privacy? There are two basic ways to secure a network: prevent bad things from happening, and watch closely for bad things and prosecute those who commit them. Since our current preventative measures like authentication and authorization seem to be failing to adequately protect the network, we have turned more toward auditing and monitoring-first as a complement, and now increasingly as a substitute-for prevention. I discuss the impact security concerns is having on privacy, and suggest that today's trend of solving security by detecting intrusions through monitoring is a reaction to institutional paranoia as well as woefully inadequate software development processes. I argue that monitoring alone can't provide sufficient protection, and that in fact the trend of relying increasingly on intrusion detection systems tells us that we are really losing ground-not gaining-on providing computer security.","PeriodicalId":203990,"journal":{"name":"Second IEEE International Symposium on Network Computing and Applications, 2003.

Since a single jitter measurement takes two delay samples to calculate, the time scale over which the two delay samples are taken may affect the statistics of measured jitter. The current common practice of calculating jitter statistics is by treating all measurements as valid samples of the same sampling space. In this paper, we perform scaling analyses on measured delay sequences to show that the proper way of conducting jitter statistic analysis is by first grouping jitter samples into different clusters each containing samples that are taken over the same or similar time scales, and then carrying out statistic analysis separately on these clusters. This special treatment is desired due to the existence of strong short-range dependency among packet delays, which is introduced by queueing effect. The tool selected to perform the scaling analysis is called Deviation-Lag Function (DLF). We show that some congestion-related information of congested end-to-end paths can be derived from their DLF plots. We also discuss the potential usage of DLF for bottleneck queue detection.","PeriodicalId":203990,"journal":{"name":"Second IEEE International Symposium on Network Computing and Applications, 2003.

In particular, as wavelength division multiplexing (WDM) technique emerges as a promising solution to meet the rapidly growing demands on bandwidth in present communication networks, supporting multicast at the WDM layer becomes an important yet challenging issue. In this paper, we present a new analytical model to compute blocking probabilities for multicast connections in WDM switching networks. Due to the non-uniform nature of multicast traffic, calculating blocking probability in a WDM multicast switching network becomes much more challenging than that under unicast traffic. Based on the link independence and wavelength independence assumptions, our model can calculate the blocking probability of any multicast connection from a single source to multiple destinations in WDM switching networks with various types of wavelength conversion capabilities, ranging from no wavelength conversion, to limited wavelength conversion, to full wavelength conversion. Our analytical results indicate that similar to unicast traffic, a significant improvement in the blocking performance of the network under multicast traffic can be achieved by limited wavelength conversion. We view that utilizing limited wavelength conversion with relatively small conversion degrees in WDM multicast switching networks is a more cost-effective choice. We also validate the analytical model through extensive simulations.","PeriodicalId":203990,"journal":{"name":"Second IEEE International Symposium on Network Computing and Applications, 2003.

The proposed fault tolerant memory provides two distinctive repair mechanisms: the permanent laser redundancy reconfiguration during the wafer probe stage in the factory to enhance its manufacturing yield and the dynamic BIST/BISD/BISR (built-in-self-test-diagnosis-repair)-based reconfiguration of the redundant resources in field to maintain high field reliability. The system reliability which is mainly determined by hardware configuration demanded by software and field reconfiguration/repair utilizing unused processor and memory modules is referred to as HW/SW Co-reliability. Various system configuration options in terms of parallel processing unit size and processor/memory intensity are also introduced and their HW/SW Co-reliability characteristics are discussed. A modeling and assurance technique for HW/SW Co-reliability with emphasis on the dependability assurance techniques based on combinatorial modeling suitable for the proposed memory design is developed and validated by extensive parametric simulations. Thereby, design and Implementation of memory-reliability-optimized and highly reliable fault-tolerant field reconfigurable massively parallel computing systems can be achieved.","PeriodicalId":203990,"journal":{"name":"Second IEEE International Symposium on Network Computing and Applications, 2003.
