    • A distributed system for the management of distributed resources interconnected by a computer network and comprised of a plurality of limited supply resources (such as those associated with multimedia content servers, e.g., bandwidth, CPU, storage, etc.,). The system comprises a plurality of server resources, preferably with target multimedia content, real time processing engines, etc., and a plurality of intermediary system resources (such as directories and resource monitors). The resources in any particular server are classified or partitioned as global or local, where the ratio of global to local is specified and controlled by the system. The system assigns clients across local and global resources and coordinates the placement of replicas of target content across global resources. The placement is dynamic and performed when necessary based on the analysis of utilization patterns of target content and replicas by pluralities of clients.
    • 用于管理由计算机网络互连并由多个有限供应资源(例如与多媒体内容服务器(例如带宽,CPU,存储等)相关联的资源)组成的分布式资源的分布式系统。 该系统包括多个服务器资源,优选地具有目标多媒体内容,实时处理引擎等,以及多个中间系统资源(诸如目录和资源监视器)。 任何特定服务器中的资源被分类或分区为全局或本地,其中全局与局部的比率由系统指定和控制。 系统为客户端分配本地和全球资源,并协调跨全球资源的目标内容副本的位置。 展示位置是动态的,必要时可以根据目标内容的利用模式和多个客户端的副本进行分析。

    • A Resource Management Framework (RMF) comprises an extensible, distributed, policy-based, object-oriented system and method for resource discovery and negotiation during the setup and control of a media session between one or more media servers and end users. The scope of the RMF framework is the management of multimedia resources used during simple, non-interactive as well as composite, complex, interactive multimedia sessions. The RMF enables iterative negotiated mapping over the requirements of an RMF-compliant application onto the offerings of one or more RMF-compliant media servers. It is an open-services architecture providing the ability to insert and apply services to enhance the suitability of offerings to requirements and vice versa, during a negotiated mapping session. Moreover, the RMF negotiated mapping algorithm itself is customizable via the use of policies (herein referred to as per-flow policies). The policies used to drive management decisions and service selections during these negotiated mapping are ‘pluggable’. New or updated policies may be added, to augment or replace an existing policy so as to realize new behavior or refine existing behavior.
    • 资源管理框架(RMF)包括在一个或多个媒体服务器和最终用户之间的媒体会话的建立和控制期间用于资源发现和协商的可扩展的,分布式的,基于策略的面向对象的系统和方法。 RMF框架的范围是在简单,非交互以及复合,复杂,交互式多媒体会话期间使用的多媒体资源的管理。 RMF支持将符合RMF的应用程序的要求进行迭代协商映射到一个或多个兼容RMF的媒体服务器的产品上。 在协商的映射会话期间,它是一种开放式服务体系结构,能够插入和应用服务,以提高产品对要求的适用性,反之亦然。 此外,RMF协商映射算法本身可以通过使用策略(这里称为每流策略)进行定制。 在这些协商映射期间用于驱动管理决策和服务选择的策略是“可插拔的”,可以添加新的或更新的策略,以增加或替换现有策略,以实现新行为或改进现有行为。
