Reduce, reuse, recycle: an approach to building large Internet caches

Abstract

New demands brought by the contirruing growth of the Internet will be met in part by more gective use of caching in the Web and other services. We have developed CRISP, a distributed Internet object cache targeted to the needs of the organizations that aggregate the end users of Internet services, particularly the commercial Internet Service Providers (ISPs) where much of the new growth occurs.A CRISP cache consists of a group of cooperating caching servers sharing a central directory of cached objects. This simple and obvious strategy is easily overlooked due to the well-known drawbacks of a centralized structure. However, we show that these drawbacks are easily overcome for well-configured CRISP caches.We outline the rationale behind the CRISP design, and report on early studies of CRISP caches in actual use and under synthetic load. While our experience with CRISP to date is at the scale of hundreds or thousands of clients, CRISP caches could be deployed to maximize capacity at any level of a regional or global cache hierarchy.

An interactive video delivery and caching system using video summarization

“…When a proxy receives a request to an object that is missing from its cache, it checks whether the object is cached on other proxies within the cooperative network. The most well known schemes are broadcast probing [5], [24], [28], directory service based [8], [9], [21], and hash-partitioned namespace approach [25].…”

A Scalable Architecture for Cooperative Web Caching

“…A hybrid cooperation protocol that is more related to the 2TC protocol is CRISP by Chase et al [13,18]. Similarly to 2TC, CRISP combines an informed protocol with a query approach to build a scalable cooperation mechanism.…”

“…In such a way, integration of existing distributed caches (e.g., a group of proxies cooperating with CRISP [13]) into a two-tier infrastructure becomes easier because such a group of cooperating caches can become a first tier cluster with little modifications.…”

“…Reduce is reducing goods consumption such as paperless, etc. Recycle is reprocessing and reuse the waste for other purposes [6].…”
