Book excerpt: The growing demand for video streaming is straining the current Internet, and mandating a novel approach to future Internet paradigms. The advent of Information-Centric Networks (ICN) promises a novel architecture for addressing this exponential growth in data-intensive services, of which video streaming is projected to dominate (in traffic size). In this thesis, I present a novel strategy in ICN for adaptive caching of variable video contents tailored to different sizes and bit rates. My objective is to achieve optimal video caching to reduce access time for the maximal requested bit rate for every user. At its core, my approach capitalizes on a rigorous delay analysis and potentiates maximal serviceability for each user. I incorporate predictors for requested video objects based on a popularity index (Zipf distribution). In my proposed model, named DASCache, I present queuing analysis for Round-Trip Time (RTT) of cached objects, providing a cap on expected delay in accessing video content. In DASCache, I present a Binary Integer Programming (BIP) formulation for the cache assignment problem, which operates in rounds based on changes in content requests and popularity scores. DASCache reacts to changes in network dynamics that impact bit rate choices by heterogeneous users and enables users to stream videos, maximizing Quality of Experience (QoE). To evaluate the performance of DASCache, in contrast to current benchmarks in video caching, I present an elaborate performance evaluation carried out on ndnSIM, over NS-3.

Book Synopsis Caching Strategies for Private and Efficient Content Retrieval in Information-Centric Networks by : Noor Abani
Download or read book Caching Strategies for Private and Efficient Content Retrieval in Information-Centric Networks written by Noor Abani and published by . This book was released on 2018 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the recent years, we have witnessed an explosive growth of content on the Internet (storage, retrieval, delivery). Consequently, the usage of computer networking shifted from sharing hardware and processing resources, as its purpose was in the early days of its creation, to accessing and sharing content instead. Therefore, the current TCP/IP Internet architecture, having been designed for the former purpose, is facing several problems in adapting to that phenomenal increase in content. Information Centric Networking (ICN) is a proposal for a future network architecture to better adapt to the current needs of users connected to the Internet. ICN shifts from the current host-centric TCP/IP architecture to one where content is the focal point. Specifically, IP addresses are replaced by content names as the main identifier for packet routing and forwarding. Disposing of the end-to-end principle that keeps end-to-end transactions unaware of resources and content available along the path, ICN leverages in-network caching to make content distribution more efficient by reducing network traffic, download time and server load. While in-network caching is a potential performance booster, if done naively, it can hinder full exploitation of its benefits and also pose several privacy threats. In this thesis, we aim at proposing caching mechanisms that could achieve efficient content distribution while also providing privacy guarantees to the requester of content. In current ICN implementations, the default caching strategy is one where each router caches every piece of content that passes through it. It has been shown in previous work that such a universal mode of caching is inefficient, highly redundant, incurring high replacement rates and also privacy breaching. This thesis addresses the aforementioned limitations by designing caching strategies that aim at reducing redundancy, replacement rates and protect user privacy. The problem is first formulated as an optimization problem that finds the optimal storage allocation and content placement that minimizes data delivery costs subject to storage budget and link capacities while also taking into account content popularity profiles. Given that such constraints might not be available a priori, we also propose two popularity-based caching strategies where routers autonomously track content popularity and progressively cache file chunks as the file gets more popular. We acknowledge the lack of consideration for the effect of content popularity dynamics in previous caching schemes, and emulate content popularity dynamics by simulating spatial and temporal locality of content items to study its effect on in-network caching policies. In addition to its inefficiency, universal caching has also caused the emergence of several privacy risks. Timing attacks are one such privacy breach where attackers use timing analysis of data retrievals to analyze users' interests in particular content. In this thesis, we explain the vulnerability of ICN to timing attacks and propose centrality-based caching to mitigate such attacks and use the anonymity set privacy metric to show that our strategy does provide privacy guarantees. Moreover, our simulations show that we can still achieve high hit rates and low delays while alleviating the network's vulnerability to timing attacks. Lastly, we also design a proactive caching strategy for ICN where user content is prefetched and cached before it is requested. Previously, proactive caching has been considered for edge networks only. In this thesis, we design a proactive caching strategy that leverages ICN's flexibility of caching data anywhere in the network, rather than just at the edge. Such leverage allows for reducing redundant caching to combat prediction uncertainty by prefetching at routers at levels higher in the network hierarchy. The end goal of this thesis is a better understanding of the limitations of a universal caching policy, in addition to designing both reactive and proactive caching strategies that, in comparison, provide more efficient content retrieval, while also protecting user privacy.

Book Synopsis Improved Caching Strategies for Publish/subscribe Internet Networking by : Kendra K. Beckler
Download or read book Improved Caching Strategies for Publish/subscribe Internet Networking written by Kendra K. Beckler and published by . This book was released on 2015 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The systemic structure of TCP/IP is outdated; a new scheme for data transportation is needed in order to make the internet more adaptive to modern demands of mobility, information-driven demand, ever-increasing quantity of users and data, and performance requirements. While an information centric networking system addresses these issues, one required component for publish subscribe or content-addressed internet networking systems to work properly is an improved caching system. This allows the publish subscribe internet networking to dynamically route packets to mobile users, as an improvement over pure hierarchical or pure distributed caching systems, To this end, I proposed, implemented, and analyzed the workings of a superdomain caching system. The superdomain caching system is a hybrid of hierarchical and dynamic caching systems designed to continue reaping the benefits of the caching system for mobile users (who may move between neighboring domains in the midst of a network transaction) while minimizing the latency inherent in any distributed caching system to improve upon the content-addressed system.

Download or read book Stochastic Network Optimization with Application to Communication and Queueing Systems written by Michael Neely and published by Springer Nature. This book was released on 2022-05-31 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text presents a modern theory of analysis, control, and optimization for dynamic networks. Mathematical techniques of Lyapunov drift and Lyapunov optimization are developed and shown to enable constrained optimization of time averages in general stochastic systems. The focus is on communication and queueing systems, including wireless networks with time-varying channels, mobility, and randomly arriving traffic. A simple drift-plus-penalty framework is used to optimize time averages such as throughput, throughput-utility, power, and distortion. Explicit performance-delay tradeoffs are provided to illustrate the cost of approaching optimality. This theory is also applicable to problems in operations research and economics, where energy-efficient and profit-maximizing decisions must be made without knowing the future. Topics in the text include the following: - Queue stability theory - Backpressure, max-weight, and virtual queue methods - Primal-dual methods for non-convex stochastic utility maximization - Universal scheduling theory for arbitrary sample paths - Approximate and randomized scheduling theory - Optimization of renewal systems and Markov decision systems Detailed examples and numerous problem set questions are provided to reinforce the main concepts. Table of Contents: Introduction / Introduction to Queues / Dynamic Scheduling Example / Optimizing Time Averages / Optimizing Functions of Time Averages / Approximate Scheduling / Optimization of Renewal Systems / Conclusions
