Web caching and content distribution: a view from the interior

S. Gadde, J. Chase, M. Rabinovich
2001 Computer Communications  
properties:an interior cache sees all requests for each assigned object x from a population of size N I every interior cache sees an equivalent object popularity distribution (n/λ held constant) all requests  ...  C is just a normalizing constant for the Zipf-like popularity distribution (a PDF).  ...  Hit ratios grow rapidly with covered population. ÿ Edge cache populations (N L ) are key: is it one thousand or one million? With large N L , interior ratios are deceptive.  ...

We propose a novel two-level distributed architecture for the support of efficient content adaptation and delivery services.  ...  other tasks, such as content adaptation, caching and fetching.  ...  The second level consists of geographically distributed clusters executing the tasks of adaptation and caching that are expensive from a computation and storage point of view, respectively.  ...

Site-autonomous distributed semantic caching

Norvald H. Ryeng, Jon Olav Hauglid, Kjetil Nørvåg
2011 Proceedings of the 2011 ACM Symposium on Applied Computing - SAC '11  
These semantic descriptions can be used to improve execution time for similar queries by retrieving some data from cache and issuing a remainder query for the rest.  ...  In large-scale distributed database systems, using a central server with complete knowledge of the system will be a serious bottleneck and single point of failure.  ...  It also knows the contents of its own cache and the usage statistics of that cache.  ...

Adaptive Caching in the YouTube Content Distribution Network: A Revealed Preference Game-Theoretic Learning Approach

William Hoiles, Omid Namvar Gharehshiran, Vikram Krishnamurthy, Ngoc-Dung Dao, Hang Zhang
2015 IEEE Transactions on Cognitive Communications and Networking  
This paper considers two cognitive aspects regarding the problem of distributed caching with limited capacity in a content distribution network that serves YouTube users with multiple edge servers: first  ...  The utility function tradesoff the placement cost for caching videos locally with the latency cost associated with delivering the video to the users from a neighboring server.  ...  Using a uniform distribution for sampling from C(µ o,n ) is no loss of generality since it assumes no prior on the interior points of C(µ o,n ), and matches the essence of convergence to a set.  ...

Deploying Video-on-Demand Services on Cable Networks

Matthew S. Allen, Ben Y. Zhao, Rich Wolski
2007 27th International Conference on Distributed Computing Systems (ICDCS '07)  
Efficient video-on-demand (VoD) is a highly desired service for media and telecom providers. VoD allows subscribers to view any item in a large media catalog nearly-instantaneously.  ...  from a deployed VoD system to evaluate different design decisions.  ...  Otherwise, the cache retrieves the data from a server, forwarding the response to the client and possibly caching it in the process.  ...

YDBT introduces a new caching scheme, new mechanisms and policies to split nodes, new ways to handle and avoid contention, and a new approach to tree snapshots ( §4).  ...  Yesquel has a new architecture and a new distributed data structure, called YDBT, which Yesquel uses for storage, and which performs well under contention by many concurrent clients.  ...  We are indebted especially to Roy Levin and Michael D. Schroeder for creating a rich and fertile research environment, where this work could blossom, at the late MSR Silicon Valley.  ...

Locality, Statefulness, and Causality in Distributed Information Systems (Concerning the Scale Dependence Of System Promises) [article]

2019 arXiv   pre-print
This paper outlines the simple view of state and causation in Promise Theory, which accounts for the scaling of processes and the relativity of different observers in a natural way.  ...  With increasingly data intensive processes over widely separated distributed deployments, e.g. in the Internet of Things and AI applications, the effects of instability need a more careful treatment.  ...  Acknowledgment: I'm grateful to Kenny Bastani, Jonas Bonér, Andrew Cowie, and Daniel North for commenting on drafts and offering references.
