Variable QoS from Shared Web Caches: User-Centered Design and Value-Sensitive Replacement
Due to differences in server capacity, external bandwidth, and client demand, some Web servers value cache hits more than others. Assuming that a shared cache knows the extent to which different servers value hits, it may employ a value-sensitive replacement policy in order to generate maximum aggregate value for servers. We consider both the prediction and value aspects of this problem and int...
متن کاملBiased Replacement Policies for Web Caches: Di erential Quality-of-Service and Aggregate User Value
Disk space in shared Web caches can be diverted to serve some system users at the expense of others. Cache hits reduce server loads, and if servers desire load reduction to di erent degrees, a replacement policy which prioritizes cache space across servers can provide di erential quality-of-service (QoS). We present a simple generalization of leastfrequently-used (LFU) replacement that is sensi...

متن کاملCost Sensitive Space Management in Shared Web Caches
In this paper, we present a new Web cache sharing scheme. Our scheme reduces the duplicated copies of the same objects in global shared Web caches, even though the hot working set of each local cache can be duplicated. Experimental results show that the proposed scheme outperforms existing sharing schemes for the data set we considered.
متن کاملBehavioral Considerations in Developing Web Information Systems: User-centered Design Agenda
The current paper explores designing a web information retrieval system regarding the searching behavior of users in real and everyday life. Designing an information system that is closely linked to human behavior is equally important for providers and the end users. From an Information Science point of view, four approaches in designing information retrieval systems were identified as system-...
