Improving Internet archive service through proxy cache

Hsiang‐Fu Yu, Yi‐Ming Chen, Shih‐Yong Wang, Li‐Ming Tseng
2003 Internet Research  
However, we find the hit rate of archives in cache servers is quite low although archives are responsible for a large percentage of network traffic.  ...  A system was implemented and operated on a real environment to evaluate the approach. 2 Empirical results indicate that the reuse rate of cached objects increased by 18% to 37%.  ...  Acknowledgement The authors would like to thank the National Science Council of the Republic of 20 China for financially supporting this research under Contract No. NSC 91-2213-E-008-016.  ...

Watch global, cache local: YouTube network traffic at a campus network: measurements and implications

Michael Zink, Kyoungwon Suh, Yu Gu, Jim Kurose, Reza Rejaie, Roger Zimmermann
2008 Multimedia Computing and Networking 2008  
We analyze how the content distribution in YouTube is realized and then conduct a measurement study of YouTube traffic in a large university campus network.  ...  The results of these simulations show that client-based local caching, P2P-based distribution, and proxy caching can reduce network traffic significantly and allow faster access to video clips.  ...  In case of a cache hit the client can play the video clip from its own cache or retrieve it from another client in the campus network.  ...

Evolutionary design of en-route caching strategies

Jürgen Branke, Pablo Funes, Frederik Thiele
2007 Applied Soft Computing  
Caching, i.e. storing replicas of previously-seen objects for later reuse, has the potential for generating large bandwidth savings and in turn a significant decrease in response time.  ...  En-route caching is the concept that all nodes in a network are equipped with a cache, and may opt to keep copies of some documents for future reuse [X. Tang, S.T.  ...  Proxy servers sometimes have caching capability, being able to optimize Internet access for a group of users in a closed environment, such as a corporate office or a campus network.  ...

Caching Policy for Cache-enabled D2D Communications by Learning User Preference

2018 IEEE Transactions on Communications  
Simulation results show a remarkable performance gain of the caching policy with user preference over existing policy with content popularity, both with realistic data set and synthetic data validated  ...  Prior works in a designing caching policy do not distinguish content popularity with user preference.  ...  In Fig. 7 , we show the impact of interference on the performance gain of the proposed solution.  ...
