Abstract

Official abstract text for this publication.

Disclosed is a method and system for maximizing the use of available bandwidth on an ISP communication system between an Internet Service Provider (ISP) and remote locations where at least one of the remote locations has a remote cache. An embodiment may create a pool of the cacheable objects being sent to the remote locations from the downstream traffic. An embodiment may determine bandwidth savings for each object in the pool of cacheable objects that would be achieved by remotely caching each object and prioritize the pool of cacheable objects based on the determined bandwidth savings for each object. An embodiment may create a queue of objects to multicast to the remote caches based on the pool of cacheable objects and the remaining multicast bandwidth and then multicast the queue to the remote caches. The remote caches may intercept and reply to requests for objects held in the remote cache without accessing the ISP communication system, thus, saving bandwidth on the ISP communication system.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for communication by an Internet Service Provide (ISP) in a communication system, said ISP connected to at least one remote location having a remote cache via an ISP communication system, said method comprising: identifying, at a computerized harvester of said ISP, a pool of cacheable objects based on downstream unicast communication traffic, said pool of cacheable objects being requested objects contained in downstream unicast replies of said down…
