    • Accelerated channel change (ACC) strategies are described for supplying a client module with media information by transitioning between a first delivery of media information provided by first delivery functionality and a second delivery of media information provided by second delivery functionality without exceeding prescribed data rate limitations. The first delivery functionality can represent server-based functionality for delivering a unicast stream of media information at a data rate (or maximum data rate) of some excess amount over the nominal rate of delivery, starting at a selected location within the media information. The second delivery functionality can represent any functionality for delivering the media information at the data rate (or maximum data rate) of the nominal rate of delivery. A join interval separates the first delivery at the excess rate and the second delivery at the nominal rate. In that period, the first delivery functionality can provide media information at a join interval data rate. The join interval data rate, if it is below the nominal data rate, will cause the client module to miss packets of media information. The client module can receive these missing packets by issuing retry requests to the first delivery functionality or to some other entity. The client module can determine the excess amount available by investigating the amount of missing information that occurs at different data rates; or the excess amount can be defined in advance.

    • Strategies are described for determining a configuration of information-transmission infrastructure. The information-transmission infrastructure includes a number of server modules for providing services to a collection of client modules. The configuration first involves determining whether a number of specified requirements can be satisfied using an input scaling equation. If so, the configuration proceeds by determining the number of server modules to deploy to satisfy the requirements using an output scaling equation, which determines the number m of server modules based on a linear transformation of the expected number of client modules. The configuration then involves assigning particular services to the server modules using either a probabilistic technique or a hash table technique. When deployed, all of the m server modules function as active sever modules (e.g., without the use of dedicated standby modules).
    • 描述了确定信息传输基础设施配置的策略。 信息传输基础设施包括用于向客户端模块集合提供服务的多个服务器模块。 该配置首先涉及使用输入缩放方程确定是否可以满足若干指定的要求。 如果是这样,则通过使用输出缩放方程来确定要部署以满足要求的服务器模块的数量,该配置将基于预期数量的客户端模块的线性变换来确定服务器模块的数量m。 然后,该配置涉及使用概率技术或哈希表技术向服务器模块分配特定服务。 部署时,所有m个服务器模块都作为活动服务器模块(例如,不使用专用备用模块)。
