    • A method and apparatus for performing template-based prefix caching advantageously identifies common prefixes (i.e., initial video segments) in video titles, stores common prefixes only once in a prefix cache, and uses these common prefixes when serving requests for video content. This advantageously enables a prefix cache to scale to a large number of video titles, since the cache stores each common prefix only once. A new video title that uses an already existing prefix may be advantageously added without requiring additional storage in the prefix cache. Template-based prefix caching also advantageously reduces the bandwidth required to distribute prefixes when new titles are ingested into the system—if the required template is already available in the prefix cache, prefix-caching is enabled instantly for this title and no additional bandwidth is required to distribute the prefix.
    • 用于执行基于模板的前缀缓存的方法和装置有利地识别视频标题中的公共前缀(即,初始视频片段),在前缀高速缓存中仅存储一次公共前缀,并且在为视频内容提供请求时使用这些公共前缀。 这有利地使得前缀高速缓存能够扩展到大量视频标题,因为高速缓存仅存储每个公共前缀一次。 可以有利地添加使用已经存在的前缀的新的视频标题,而不需要前缀高速缓存中的附加存储。 基于模板的前缀缓存还有利地减少了当新标题被摄入系统时分配前缀所需的带宽 - 如果所需的模板在前缀高速缓存中已经可用,则为该标题立即启用前缀缓存,并且不需要额外的带宽 分发前缀。

    • The present invention supports services that span multiple service domains. In one embodiment, the present invention provides service-level interaction between an enterprise network and a non-enterprise network (or networks), thereby enabling enterprise users at remote locations (i.e., at home, on vacation, or at other locations remote from the enterprise location) to use services typically only available to the enterprise users while at the enterprise location (e.g., while in the office). The present invention provides a calendar notification service, whereby a calendar notification originating in an enterprise network is provided to a remote enterprise user via a non-enterprise network. The present invention provides an enterprise dialing plan service, whereby a remote enterprise user may register a remote user device to be able to use an enterprise dialing plan. Once registered, the remote enterprise user may use the enterprise dialing plan from the remote user device to place calls to local enterprise users at local user devices connected to the enterprise network and, similarly, local enterprise users may use the enterprise dialing plan to place calls to the remote enterprise user at the remote user device.
    • 本发明支持跨多个服务域的服务。 在一个实施例中,本发明提供企业网络和非企业网络(或网络)之间的服务级别交互,从而使远程位置(即,在家中,假期或远离其他位置的企业用户) 企业位置)使用通常仅在企业位置(例如,在办公室)期间对企业用户可用的服务。 本发明提供一种日历通知服务,由此通过非企业网络向远程企业用户提供源自企业网络的日历通知。 本发明提供企业拨号计划服务,由此远程企业用户可以注册远程用户设备以能够使用企业拨号计划。 一旦注册,远程企业用户可以使用来自远程用户设备的企业拨号计划,在连接到企业网络的本地用户设备上拨打本地企业用户的呼叫,同样,本地企业用户可以使用企业拨号计划拨打电话 到远程用户设备上的远程企业用户。
