TLDR
This paper presents a new, delay-conscious cache replacement algorithm LNC-R-W3 which maximizes a performance metric called delay-savings-ratio and compares it with other existing cache replacement algorithms, namely LRU and LRU-MIN.Abstract:
Caching at proxy servers plays an important role in reducing the latency of the user response, the network delays and the load on Web servers. The cache performance depends critically on the design of the cache replacement algorithm. Unfortunately, most cache replacement algorithms ignore the Web's scale. In this paper we argue for the design of delay-conscious cache replacement algorithms which explicitly consider the Web's scale by preferentially caching documents which require a long time to fetch to the cache. We present a new, delay-conscious cache replacement algorithm LNC-R-W3 which maximizes a performance metric called delay-savings-ratio. Subsequently, we test the performance of LNC-R-W3 experimentally and compare it with the performance of other existing cache replacement algorithms, namely LRU and LRU-MIN.read more

Flexible Integrated Cache for Efficient Information Access in Mobile Computing Environments
Mohan Kumar,Sajal K. Das +1 more
TL;DR: In this paper, the authors proposed an integrated caching scheme for mobile computing environments, where cached (traditional), prefetched, and push cached items compete with each other for cache space.

Patent
Externalized execution of input method editor
TL;DR: In this paper, a facility for processing textual input generated with a user input device is described, which stores the textual input in a first data structure (212) contained in the address space of a first process.
Improving resource utilization of enterprise-level world wide web proxy servers
TL;DR: This work automates prefetch strategies of high accuracy and medium coverage and finds that 99% of this prefetchable bandwidth is based on objects that the Web proxy server under study has not accessed before.
Patent
Voice value-added service data information processing method
TL;DR: In this paper, the disclosed process method for data information in voice value added business comprises: building cache access zone to store the data file and update the cache zone according to use frequency of last file; when need data file, indexing in the cache Zone according to file label to decide whether the file in the zone; if yes, calling the file directly; or else, calling file from server

The LRU-K page replacement algorithm for database disk buffering
TL;DR: The LRU-K algorithm surpasses conventional buffering algorithms in discriminating between frequently and infrequently referenced pages, and adapts in real time to changing patterns of access.

A hierarchical internet object cache
TL;DR: The design and performance of a hierarchical proxy-cache designed to make Internet information systems scale better are discussed, and performance measurements indicate that hierarchy does not measurably increase access latency.

Characteristics of WWW Client-based Traces
TL;DR: This paper presents a descriptive statistical summary of the traces of actual executions of NCSA Mosaic, and shows that many characteristics of WWW use can be modelled using power-law distributions, including the distribution of document sizes, the popularity of documents as a function of size, and the Distribution of user requests for documents.
Caching Proxies: Limitations and Potentials
TL;DR: This work assesses the potential of proxy servers to cache documents retrieved with the HTTP protocol, and finds that a proxy server really functions as a second level cache, and its hit rate may tend to decline with time after initial loading given a more or less constant set of users.
