Refreshment policies for Web content caches
Proceedings IEEE INFOCOM 2001. Conference on Computer Communications. Twentieth Annual Joint Conference of the IEEE Computer and Communications Society (Cat. No.01CH37213), 2002Web content caches are often placed between end-users and origin servers as a mean to reduce server load, network usage, and ultimately, user-perceived latency. Cached objects typically have associated expiration times, after which they are considered stale and must be validated with a remote server (origin or another cache) before they can be sent to ...

Caching dynamic contents with varying popularity
2021 19th International Symposium on Modeling and Optimization in Mobile, Ad hoc, and Wireless Networks (WiOpt), 2021We study content caching in a cellular network consisting of a base station with a cache. New contents arrive in the network according to a Poisson process and the contents stay for exponentially distributed times. At any given time, all the contents in the network have the same popularity or request rate. Also, contents’ request rates are time-varying,

Content discovery and caching in mobile networks
21st Annual IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2010We consider content discovery in wireless networks with infrastructure, where mobile nodes store, advertise and consume contents while Broker entities running on infrastructure devices let demand and offer meet. We refer to this paradigm as match-making, highlighting its features within the confines of the standard publish-and-subscribe paradigm.

Dynamic cache rental and content caching in elastic wireless CDNs
2018 16th International Symposium on Modeling and Optimization in Mobile, Ad Hoc, and Wireless Networks (WiOpt), 2018With elastic CDNs, content providers can rent cache space on demand at different cloud locations in order to enhance their offered quality of service (QoS). This paper addresses a key challenge in this context, namely how to invest an available budget in cache space in order to match spatio-temporal fluctuations of file demand and storage price ...

Tube caching: An effective caching scheme in Content-Centric Networking
2016 IEEE/ACM 24th International Symposium on Quality of Service (IWQoS), 2016We investigated the cache allocation and replacement problems in CCN within a single ISP and propose the scheme called Tube Caching that can dynamically distribute contents across the forwarding paths based on the energy-related benefit. Through the preliminary evaluations, Tube Caching has been proven to be effective.

Distributed cache management considering content popularity for in-network caching
2017 23rd Asia-Pacific Conference on Communications (APCC), 2017This paper proposes a new cache management method considering the popularity of contents for in-network caching. In networks with in-network caching, routers store contents in their cache and users can download them from the routers. By utilizing cached contents, the loads for content servers and networks can be reduced.

Efficiency of caches for content distribution on the Internet
2010 22nd International Teletraffic Congress (lTC 22), 2010Traffic engineering and an economical provisioning of bandwidth is crucial for network providers in times of high competition in broadband access networks. We investigate the efficiency of caching as an option to shorten end-to-end paths and delays while at the same time reducing traffic loads.

Enhanced Proxy Caching with Content Management
Knowledge and Information Systems, 2002In this paper, we propose a novel approach to enhancing web proxy caching, an approach that integrates content management with performance tuning techniques. We first develop a hierarchical model for management of web data, which consists of physical pages, logical pages and topics corresponding to different abstraction levels. Content management based

Content Classification for Caching under CDNs
2007 Innovations in Information Technologies (IIT), 2007Content delivery networks (CDNs) provide an efficient support for serving "resource-hungry" applications while minimizing the network impact of content delivery as well as shifting the traffic away from overloaded origin servers. However, their performance gain is limited since the storage space in CDN's servers is not used optimally.

Caching Partial Files for Content Delivery
2019 National Conference on Communications (NCC), 2019Numerous empirical studies have shown that users of video-on-demand platforms do not always watch videos in their entirety. A direct consequence of this is that not all parts of a video are equally popular. Motivated by this, we explore the benefits of dividing files into smaller segments for caching. We treat incoming requests as requests for segments
