....NPS decreases response times by 25 . 1 Introduction A number of studies have demonstrated the bene ts of web prefetching [12, 17, 24, 25, 32, 33, 42, 52] And the attractiveness of prefetching appears likely to rise in the future as the falling prices of disk storage [14] and network bandwidth [41] make it increasingly attractive to trade increased consumption of these resources to improve response time and availability and thus reduce human wait time [7] Despite these bene ts, prefetching systems have not been widely deployed because of two concerns: interference and deployability. ....

.... costs of prefetching [7, 21] Second, appropriate thresholds to balance costs and bene ts may vary over time as client, network, and server load conditions change over seconds (e.g. changing workloads or network congestion [56] hours (e.g. diurnal patterns) and months (e.g. technology trends [7, 41]) Our goal is to construct a self tuning resource module that prevents prefetch requests from interfering with demand requests. Such an architecture will simplify the design of prefetching systems by separating the tasks of prediction and resource management. Prediction algorithms may specify ....

.... frequently as data change [13, 50, 48] Technology trends suggest that wasting bandwidth and storage to improve latency and availability will become increasingly attractive in the future: per byte network transport costs and disk storage costs are low and have been improving at 80 100 per year [9, 17, 37]; conversely network availability [11, 40, 54] and network latencies improve slowly, and long latencies and failures waste human time. Current operating systems and networks do not provide good support for aggressive background transfers. In particular, because background transfers compete with ....

Dahlin was also supported by an NSF CAREER award (CCR 9733842) and an Alfred P. Sloan Research Fellowship. and months (e.g. technology trends [9, 37]) We focus on managing network resources rather than processors, disks, and memory both because other work has provided suitable end station schedulers for these local resources [10, 24, 33, 39, 45] and because networks are shared across applications, users, and organizations and therefore pose ....

Despite these bene ts, prefetching systems have not been widely deployed because of two concerns: interference and deployability. First, if a prefetching ....

Self tuning resource management seems essential for coping with network conditions that change significantly over periods of seconds (e.g. changing congestion [54] hours (e.g. diurnal patterns) and months (e.g. technology trends [9, 37]) We focus on managing network resources rather than processors, disks, and memory both because other work has provided suitable end station schedulers for these local resources [10, 24, 33, 39, 45] and because networks are shared across applications, users, and organizations and therefore pose ....

....will be difficult to successfully hand tune applications that use massive replication. Moving and storing electrons is extremely cheap, so it can make sense to waste many electrons to improve human perceived availability and latency. In particular, the rapidly falling cost of network bandwidth [5, 14] and disk storage [8] each improving at nearly 100 per year may call for more aggressive replication than intuition might first suggest. Gray and Shenoy [10] describe a back of the envelope analysis that compares the dollar value of caching data versus the dollar cost of waiting while the ....

....by law enforcement. At the same time, we have heard almost nothing about the privacy interests of law abiding citizens. Senator John Ashcroft The Internet is now beginning to fulfil its original promise as a universal communications medium. The level of traffic is currently doubling annually [Odlyzko01] and will continue to grow as connectivity is embedded into almost all electronic devices. Safety critical systems such as medical infrastructure are being brought on line. The resulting importance of the network as a piece of critical infrastructure has already led to a raft of new legislation ....
