Many food-caching animals live in groups and cache pilferage may be one of the negative consequences of social living. Several hypotheses have been proposed to suggest that individuals may benefit from caching even when cache pilferage is high if all individuals can cache and pilfer equally. Stable groups may hypothetically support the evolution of such "reciprocal pilfering" because all group ...

Future wireless systems enable content communication to be offloaded towards the network edges instead of allocating in centralized cloud. In this paper, we investigate the incentives in edge caching networks via tools from game theory by considering heterogeneous edge systems and various caching behaviors. Particularly, we analyze the competitive and cooperative interactions of multiple stakeh...

Food-storing corvids use many cache-protection and pilfering strategies. We tested whether Eurasian jays (Garrulus glandarius) reduce the transfer of auditory information to a competitor when caching and pilfering. We gave jays a noisy and a quiet substrate to cache in. Compared with when alone, birds cached less in the noisy substrate when with a conspecific that could hear but could not see t...

Caching is one of the most important schemes for improving the performance of continuous media servers. Continuous object caching enables a server to support more clients simultaneously since it reduces the disk load imposed at each round. However, without a quantative analysis of the disk load reduction induced by caching, the caching eeect can not be reeected in the admission control scheme, ...

Web proxy caching is one of the most successful solutions for improving the performance of Web-based systems. In Web proxy caching, the popular Web objects that are likely to be revisited in the near future are stored on the proxy server, which plays the key roles between users and Web sites in reducing the response time of user requests and saving the network bandwidth. However, the difficulty...

File systems that employ caching have been built for many years. However, most work in file systems has been done as part of monolithic operating systems. In this paper we give our experience with building a high-performance distributed file system on Spring, a highly modular operating system where system services such as file systems are provided as user-level servers. The Spring file system d...

Caching is a popular technique for reducing both server load and user response time in distributed systems. In this paper, we are interested in the question of whether caching might be effective for search engines as well. We study two real search engine traces by examining query locality and its implications for caching. Our trace analysis results show that: (1) Queries have significant locali...

Caching is an important technique in scaling storage for high-traffic web applications. Usually, building caching mechanisms involves significant effort from the application developer to maintain and invalidate data in the cache. In this work we present CacheGenie, a caching middleware which makes it easy for web application developers to use caching mechanisms in their applications. CacheGenie...

For many distributed data intensive applications, the default remote invocation of CORBA objects by clients is not acceptable because of performance degradation. Caching enables clients to invoke operations locally on distributed objects instead of fetching them from remote servers. This paper addresses the design and implementation of a specific caching approach for CORBA-based systems. We pro...

Web caching plays an important role in many network services. Utilization of the cache in each level (server, proxy, and client) of network forms a web caching hierarchy. A major problem of the hierarchical caching is the poor performance due to the interference between upper-level and lower-level caches. This paper investigates the replacement algorithms applied in the network caching hierarch...
