Web pages take noticeably longer to load when accessing the Internet using high latency wide-area wireless networks like 3G. This delay can result in lower user satisfaction and lost revenue for web site operators. By locating a just-in-time prefetching push proxy in the cloud and routing mobile client web requests through it, web page load times can be perceivably reduced. Our analysis and experimental...
IEEE 802.11 PHY supports multiple transmission rates, varying from as low as 1 Mbps in 802.11b, up to 54 Mbps in 802.11g, and higher in 802.11n, with each Wi-Fi station selecting its transmission rate according to its own algorithm. The per-packet fairness scheme adopted by the 802.11 MAC reduces the effective throughput to that of the lowest sending rate. In multi-vehicle opportunistic downloading...
In recent years autonomic computing, specifically autonomic data centre management has gained significant attention. Human intervention be minimized to reduce the operating costs of business applications. In this paper we focus our attention to the self-repair dimension and present a flexible probabilistic framework to develop agents for self-repair in the context of business-information-system components...
The normal operation of enterprise software systems can be modeled by stable correlations between various system metrics; errors are detected when some of these correlations fail to hold. The typical approach to diagnosis (i.e., pinpoint the faulty component) based on the correlation models is to use the Jaccard coefficient or some variant thereof, without reference to system structure, dependency...
The manual process to identifying causes of failure in distributed information systems is difficult and time-consuming. The underlying reason is the large size and complexity of these systems, and the vast amount of monitoring data they generate. Despite its high cost, this manual process is necessary in order to avoid the detrimental consequences of system downtime. Several studies and operator practice...
