    • An enterprise network architecture has a trust link established between two autonomous network systems that enables transitive resource access between network domains of the two network systems. The trust link is defined by data structures maintained by each of the respective network systems. The first network system maintains namespaces that correspond to the second network system and a domain controller in the first network system, or a first network system administrator, indicates whether to trust individual namespaces. An account managed by a domain in the second network system can request authentication via a domain controller in the first network system. The first network system determines from the trust link to communicate the authentication request to the second network system. The first network system also determines from the trust link where to communicate authorization requests when administrators manage group memberships and access control lists.
    • 企业网络架构具有建立在两个自主网络系统之间的信任链路,能够实现两个网络系统的网络域之间的传递资源访问。 信任链接由相应网络系统中的每一个维护的数据结构来定义。 第一网络系统维护对应于第二网络系统的命名空间和第一网络系统中的域控制器,或者第一网络系统管理员指示是否信任个体命名空间。 由第二网络系统中的域管理的帐户可以通过第一网络系统中的域控制器请求认证。 第一网络系统从信任链路确定将认证请求传送到第二网络系统。 当管理员管理组成员身份和访问控制列表时,第一个网络系统还从信任链接确定何处传达授权请求。

    • A network system includes a content provider connected to local service providers via an interactive distribution network, such as the Internet. The local service providers facilitate delivery of the content from the content provider to multiple subscribers. The local service providers schedule delivery of frequently requested content from the content provider prior to a peak time when the subscribers are likely to request the content. The content is downloaded from the content provider during the off-peak hours and cached at the local service providers for serving to the subscribers during the ensuing peak time. In this manner, the frequently requested content is already present at the local service providers and ready to be served to the subscribers before they actually request it. When the content is finally requested, the data is streamed continuously in real-time for just-in-time rendering at the subscribers computer. Another aspect of this invention involves supplementing content delivery over the Internet with delivery of content over a secondary network, such as a broadcast satellite network. The supplemental broadcast link offers additional bandwidth at a fraction of the cost that would be incurred if the local service provider installed additional Internet connections, such as T1 or T3 connections.
    • 网络系统包括经由诸如因特网的交互式分发网络连接到本地服务提供商的内容提供商。 本地服务提供商便于将内容从内容提供商传递到多个订阅者。 本地服务提供商在用户可能请求内容的高峰时间之前从内容提供商调度经常请求的内容的传送。 在非高峰时段,内容从内容提供商下载,并在随后的高峰时段缓存在本地服务提供商处供服务。 以这种方式,频繁请求的内容已经存在于本地服务提供商处,并且在其实际请求之前准备被发送给订户。 当最终请求内容时,数据将在用户计算机上实时连续流式传输以便及时呈现。 本发明的另一方面涉及通过诸如广播卫星网络的辅助网络上的内容传送来补充因特网上的内容传送。 如果本地服务提供商安装了​​诸如T1或T3连接的其他互联网连接,补充广播链路将以一小部分成本提供额外的带宽。
