A Survey of Cache/Proxy for Transparent Data Replication
نویسندگان
چکیده
Web caching is an important technology for reducing Internet access latency, alleviating network traffic, and spreading server load. An important issue that affects the performance of web caching is caching architecture, in which several caches are usually federated for making caches cooperate on a large scale and effectively increase the cache population. Transparent data replication is such a caching architecture, which has shown to be easy to manage and have good system scalability. In this paper, we present an survey of state-of-the-art techniques of cache/proxy placement for transparent data replication.

Placement problems for transparent data replication proxy services
Transparent data replication has been considered a promising technique for improving system performance for a large distributed network. In this paper, a hybrid transparent replication model is presented. We address the problems of replication proxy placement in the network and data replica placement on the installed proxies given that a maximum of proxies are allowed. Both reads and writes are...

Design and implementation of e ective caching schemes has been a critical issue with respect to World Wide Web objects circulation and availability Caching and replica tion have been combined and applied in prototype systems in order to reduce the overall bandwidth and increase system s fault tolerance This paper presents a model for opti mizing access performance when requesting Web objects ac...
متن کاملCooperative proxy caching for wireless base stations
This paper proposes a mobile cache model to facilitate the cooperative proxy caching in wireless base stations. This mobile cache model uses a network cache line to record the caching state information about a web document for effective data search and cache space management. Based on the proposed mobile cache model, a P2P cooperative proxy caching scheme is proposed to use a self-configured an...
متن کاملA Survey of Proxy Caching Mechanisms for Multimedia Data Streams
Although many web caching techniques have been developed to improve Web performance, existing proxy caching schemes do not support the multimedia data stream well. In this paper, we briefly describe the basic characteristics of steaming media caching and traditional web caching and discuss their dissimilarities. Then, we survey the proxy caching mechanisms for multimedia data streams, and final...
متن کاملNetCache Architecture and Deployment
This paper describes the architecture of Network Appliance’s NetCache proxy cache. It discusses sizing proxy caches, contrasts the advantages and disadvantages of transparent caching, and reviews mechanisms to provide highly available caches. It also reports cache hit rates and summarizes our experience deploying proxy caching at Internet Service Providers (ISP) and corporate firewalls and intr...
