Adaptive TTL-Based Caching for Content Delivery
SIGMETRICS '17 Abstracts: Proceedings of the 2017 ACM SIGMETRICS / International Conference on Measurement and Modeling of Computer SystemsJune 2017, Pages 45–46https://doi.org/10.1145/3078505.3078560Content Delivery Networks (CDNs) cache and serve a majority of the user-requested content on the Internet, including web pages, videos, and software downloads. We propose two TTL-based caching algorithms that automatically adapt to the heterogeneity, ...

A special class of erasure codes, known as locally repairable codes (LRCs) [...

Analysis of a Stochastic Model of Replication in Large Distributed Storage Systems: A Mean-Field Approach
SIGMETRICS '17 Abstracts: Proceedings of the 2017 ACM SIGMETRICS / International Conference on Measurement and Modeling of Computer SystemsJune 2017, Page 51https://doi.org/10.1145/3078505.3078531Distributed storage systems such as Hadoop File System or Google File System (GFS) ensure data availability and durability using replication. Persistence is achieved by replicating the same data block on several nodes, and ensuring that a minimum number ...

Expected Values Estimated via Mean-Field Approximation are 1/N-Accurate: Extended Abstract
SIGMETRICS '17 Abstracts: Proceedings of the 2017 ACM SIGMETRICS / International Conference on Measurement and Modeling of Computer SystemsJune 2017, Page 50https://doi.org/10.1145/3078505.3078523In this paper, we study the accuracy of mean-field approximation. We show that, under general conditions, the expectation of any performance functional converges at rate O(1/N) to its mean-field approximation. Our result applies for finite and infinite-...
