Concurrent Evaluation of Web Cache Replacement and Coherence Strategies

A. S.Z. Belloum, L. O. Hertzberger
2002 Simulation (San Diego, Calif.)  
When studying Web cache replacement strategies, it is often assumed that documents are static. Such an assumption may not be realistic, especially when large-size caches are considered.  ...  Using a simple cache model, they will show that the cache hits recorded when using some replacement strategies are more likely to be performed on out-of-date documents.  ...  We thank also the National Science Foundation (grants NCR-9616602 and NCR-9521745), and the National Laboratory for Applied Network Research for providing access to data used in the experiments.  ...

Replacement policies for a proxy cache

L. Rizzo, L. Vicisano
2000 IEEE/ACM Transactions on Networking  
In this paper, we analyze access traces to a Web proxy, looking at statistical parameters to be used in the design of a replacement policy for documents held in the cache.  ...  In the second part, we propose a novel replacement policy, called LRV, which selects for replacement the document with the lowest relative value among those in cache.  ...  Lorenzetti for his initial work on the LRV algorithm and J. Crowcroft for his comments. They are also grateful to DEC for making the traces of their Web proxy available for simulation purposes.  ...

A Review of Probabilistic Techniques Used for Web browsers' Caching

Abdul Sattar Kakar, Muhammad Sadiq Rohie
2020 European Journal of Engineering Research and Science  
Cache memory plays a central role in improving the performance of web servers, especially for big data transmission, which response time is constrained.  ...  It is necessary to use an effective method, such as web cache.  ...  Other objects are removed by the LRU algorithm, as the instant cache is full, then fuzzy logic is used to improve durable cache replacement decisions.  ...

Modeling correlations in web traces and implications for designing replacement policies

Konstantinos Psounis, An Zhu, Balaji Prabhakar, Rajeev Motwani
2004 Computer Networks  
A number of web cache-related algorithms, such as replacement and prefetching policies, rely on specific characteristics present in the sequence of requests for efficient performance.  ...  As an important by-product, the model provides guidelines for designing efficient replacement algorithms. We obtain optimal algorithms given the parameters of the model.  ...  LRU uses a linked list to maintain the order of the documents in the cache. However, using a simple linked list for c-LRU is not efficient.  ...

Web-log mining for predictive web caching

Qiang Yang, H.H. Zhang
2003 IEEE Transactions on Knowledge and Data Engineering  
In this paper, we present a Web-log mining method for caching Web objects and use this algorithm to enhance the performance of Web caching systems.  ...  The heart of a caching system is its page replacement policy, which selects the pages to be replaced in a cache when a request arrives.  ...  ACKNOWLEDGMENTS The authors thank Tianyi Li and Zhen Zhang for their helpful discussions in this work.  ...

A Comparison of Cache Replacement Algorithms for Video Services

Areej M. Osman, Niemah I. Osman
2018 International Journal of Computer Science & Information Technology (IJCSIT)  
In this paper we study the most popular cache replacement algorithms (OPT, CC, QC, LRU, LFU and FIFO) which are currently used in video caching.  ...  In addition, it is very important to store the right content at the right time in caches to make effective use of caching.  ...  Caching provides an efficient solution to this problem by bringing documents closer to clients [1] .  ...

Enhanced Mobile caching in Edge using Signal R and AES

Dr.T.Jaya R.S. Aashmi
2019 Zenodo  
Caching is used for lessening the latency as well as bandwidth provision for the distribution of web documents to the user.  ...  In our system,Signal R technique is used, where the cache data is shared among co-operative users. The hub connection among the co-operative users initiated by creating a server.  ...  Data Transfer using SignalR For better efficiency of web functionality for giving out cache data uses an ASP.NET SignalR as a library function.  ...

A Web Proxy Cache Coherency and Replacement Approach [chapter]

Jose Aguilar, Ernst Leiss
2001 Lecture Notes in Computer Science  
We propose an adaptive cache coherence-replacement scheme for web proxy cache systems that is based on several criteria about the system and applications, with the objective of optimizing the distributed  ...  Our coherence-replacement scheme assigns a replacement priority value to each cache block according to a set of criteria to decide which block to remove.  ...  In this paper we propose an adaptive cache coherence-replacement scheme for web proxy cache systems.  ...

Capacity Bound-free Web Warehouse

Yahiko Kambayashi, Kai Cheng
2003 Conference on Innovative Data Systems Research  
Actually in web cache systems, we can use disks and tertiary storages since access time of disks (or even online tapes) is still shorter than time required for retrieving web pages from origin severs.  ...  Thus, we can remove the restriction of cache size that has been the most severe condition for designing cache algorithms. We still need to determine the priority of data for efficient processing.  ...  Acknowledgment This work is supported in part by JSPS (Japan Society for the Promotion of Science) and CREST of JST (Japan Science and Technology Corporation). The authors would like to thank Dr.  ...
