Wormhole Caching with HTTP PUSH Method for a Satellite-Based Web Content Multicast and Replication System
نویسندگان
چکیده
A two-tier Web caching and replication system, called the INTELSAT Internet Delivery System (IDS) is discussed. Based on a Warehouse-Kiosk paradigm, IDS provides global access and Internet wormholes via a fleet of INTELSAT satellites, the largest commercial satellite communications system in the world. Web content such as cacheable HTTP, FTP and streaming objects are fetched or pushed both actively and reactively into a central repository cache via intelligent Web agents. Fresh objects are constantly sent via IP multicast reliably to registered Kiosk caches. Distributed Web caches in the Kiosks offer content to their local users directly with improved quality of service and less bandwidth cost.

Improve Replica Placement in Content Distribution Networks with Hybrid Technique
The increased using of the Internet and its accelerated growth leads to reduced network bandwidth and the capacity of servers; therefore, the quality of Internet services is unacceptable for users while the efficient and effective delivery of content on the web has an important role to play in improving performance. Content distribution networks were introduced to address this issue. Replicatin...

A number of different architectures have been proposed in support of data-oriented or information-centric networking. Besides a similar visions, they share the need for designing a new networking architecture. We present an incrementally deployable approach to content-centric networking based upon TCP. Contentaware senders cooperate with probabilistically operating routers for scalable content ...

In this paper we study satellite-caching, that is, the employment of satellite multicasting for the dissemination of prefetched content to WWW caches. This approach is currently being deployed by major satellite operators and ISPs around the world. We introduce a theoretical framework to study satellite-caching and formalize the notions of Utility and Quality of Service. We explore two charging...
