Limitations and benefits of cooperative proxy caching

IEEE Journal on Selected Areas in Communications, 2002
Cooperating proxy caches are groups of HTTP proxy servers that organize to share cached objects. This paper develops analytical models for proxy cooperation which use speedup in user response time as the performance metric. Speedup expressions are derived for the cooperation upper bound, a proxy mesh, and a three-level proxy hierarchy.

Cooperative Transmission via Caching Helpers

2015 IEEE Global Communications Conference (GLOBECOM), 2014
This paper models the cooperative transmission via caching helpers (cache-based joint transmission), which cache one of the K most popular files, in wireless cellular networks and analyzes its performance in terms of the file transmission success probability in the stochastic geometry framework.

Anycast-Based Cooperative Proxy Caching

2005
As one of the most popular applications currently running on the Internet, the World Wide Web is of an exponential growth in size, which results in the network congestion and server overloading. Web caching as an important technique aims at reducing network traffic, server load, and user-perceived retrieval delays by replicating popular contents on ...

COOP - A cooperative caching service in MANETs

Joint International Conference on Autonomic and Autonomous Systems and International Conference on Networking and Services - (icas-isns'05), 2005
Data access applications in mobile ad hoc networks (MANETs) suffer from intermittent network connections and restricted power supplies. While most of the researches focus on media access control (MAC) and routing layer solutions, we explore the possibility of application cooperation.

Adaptive Set-Granular Cooperative Caching

IEEE International Symposium on High-Performance Comp Architecture, 2012
Current Chip Multiprocessors (CMPs) consist of several cores, cache memories and interconnection networks in the same chip. Private last level cache (LLC) configurations assign a static portion of the LLC to each core. This provides lower latency and isolation, at the cost of depriving the system of the possibility of reassigning underutilized ...

A viability analysis of cooperative proxy caching

Proceedings IEEE INFOCOM 2001. Conference on Computer Communications. Twentieth Annual Joint Conference of the IEEE Computer and Communications Society (Cat. No.01CH37213), 2002
Cooperating proxy caches are groups of HTTP proxy servers that share cached objects. This paper models the speedup in average user response time for proxy cooperation and derives expressions for the upper bound, a mesh organization, and a hierarchical organization.

A cooperative cache architecture in support of caching multimedia objects in MANETs

Proceedings of the 5th ACM international workshop on Wireless mobile multimedia - WOWMOM '02, 2002
This paper presents a cooperative caching architecture suitable for continuous media (CM) proxy caching in MANET environments. The proposed scheme introduces an application manager component, which is interposed between traditional Internet CM applications and the network layer.

Cooperative Web Caching

2011
Most clients are placed behind the proxy servers on the Internet. Proxy servers have the disk cache space, network bandwidth, and availability to cache part of the objects for clients. In addition, the number of proxy servers can be increased or decreased dynamically according to the anticipated server workload, making them good candidates to alleviate

Cooperative Cache Replacement Policy for MANETs

International Journal of Advanced Pervasive and Ubiquitous Computing, 2014
Mobile Adhoc Networks (MANETs) are autonomously structured multi-hop wireless links in peer to peer fashion without aid of any infrastructure network. In MANETs network topology is dynamic, as nodes are mobile. Due to this dynamic topology and multi-hop environment data availability in MANETs is low.

Persistent cache in Cooperative Search Engine

Proceedings 22nd International Conference on Distributed Computing Systems Workshops, 2003
Cooperative Search Engine (CSE) is a distributed search engine, which can update indexes in a very short time for the purpose of fresh information retrieval. In CSE, the retrieval performance is dependent on cache contents because communication delay occurs at retrieval time.
