Scalable Consistency Maintenance in Content Distribution Networks Using Cooperative Leases
In this paper, we argue that cache consistency mechanisms designed for stand-alone proxies do not scale to the large number of proxies in a content distribution network and are not flexible enough to allow consistency guarantees to be tailored to object needs. To meet the twin challenges of scalability and flexibility, we introduce the notion of cooperative consistency along with a mechanism, c...

چکیده رساله/پایان نامه : تاکنون روشهای متعددی در ارتباط با مکان یابی خطا در شبکه انتقال ارائه شده است. استفاده مستقیم از این روشها در شبکه توزیع به دلایلی همچون وجود انشعابهای متعدد، غیر یکنواختی فیدرها (خطوط کابلی، خطوط هوایی، سطح مقطع متفاوت انشعاب ها و تنه اصلی فیدر)، نامتعادلی (عدم جابجا شدگی خطوط، بارهای تکفاز و سه فاز)، ثابت نبودن بار و اندازه گیری مقادیر ولتاژ و جریان فقط در ابتدای...
Maintaining Cache Consistency in Content Distribution Networks
While several mechanisms for maintaining consistency in single proxy caches exist today, not as much research has addressed ways in which such techniques may be extended to a cluster of proxy caches. If such techniques are not developed and deployed carefully, the overheads involved in maintaining cache consistency in large-scale systems such as Content Distribution Networks (CDNs) increases by...
متن کاملLeases for Consistency in Large -
This article introduces volume leases as a mechanism for providing server-driven cache consistency for large-scale, geographically distributed networks. Volume leases retain the good performance, fault tolerance, and server scalability of the semantically weaker client-driven protocols that are now used on the web. Volume leases are a variation of object leases, which were originally designed f...
متن کاملA Novel Approach to Managing Consistency in Content Distribution Networks
Content distribution network (CDN) is a technique deployed to push content from the origin server to geographically distributed replicas, usually located at the edge of the network where the clients are attached. One of the important problems in CDNs is how to manage the consistency of content at replicas with that at the origin server, especially for those documents changing dynamically. In th...
