    Abstract: An object caching system (100) serving an Intranet (102) includes a cache name server (106) and a plurality of web cache servers (108A-108D). Each of the plurality of web cache servers (108A-108D) couples to an Intranet (104) and to the Internet (102) and stores a respective plurality of Internet objects that have been previously retrieved from the Internet (102). The cache name server (106) couples to the Intranet (104), receives a request for an Internet object from a web client (110A) coupled to the Intranet (104), and directs the web client (110A) to a serving web cache server (108A) of the plurality of web cache servers (108A-108D) based upon the request. If the serving web cache server (108A) possesses a copy of the Internet object, it returns a copy of the Internet object to the web client (110A). However, if the serving web cache (108A) server does not possess a copy of the Internet object, it retrieves a copy of the Internet object from the Internet (102) and returns a copy of the Internet object to the web client (110A). The cache name server (106) includes a database that stores an identifier and a serving web cache server ID for each Internet object stored by the plurality of web cache servers (108A-108D). The cache name server database may also store a time stamp for each Internet object. Each web cache server (108A-108D) also includes a database that stores Internet objects and respective time stamps.

    Abstract translation: 服务于内联网(102)的对象缓存系统(100)包括缓存名称服务器(106)和多个web缓存服务器(108A-108D)。 多个web缓存服务器(108A-108D)中的每一个耦合到内部网(104)和互联网(102),并且存储先前从因特网(102)检索的相应的多个互联网对象。 缓存名称服务器(106)耦合到内部网(104),从耦合到内联网(104)的web客户端(110A)接收对互联网对象的请求,并将网络客户端(110A)引导到服务web缓存 服务器(108A),基于该请求,多个web缓存服务器(108A-108D)中的服务器(108A)。 如果服务网页缓存服务器(108A)拥有互联网对象的副本,则将互联网对象的副本返回给网络客户端(110A)。 然而,如果服务web缓存(108A)服务器不具有互联网对象的副本,则它从互联网(102)检索互联网对象的副本,并将互联网对象的副本返回给网络客户端(110A) 。 缓存名称服务器(106)包括存储由多个web缓存服务器(108A-108D)存储的每个因特网对象的标识符和服务web缓存服务器ID的数据库。 缓存名称服务器数据库还可以存储每个互联网对象的时间戳。 每个web缓存服务器(108A-108D)还包括存储互联网对象和相应时间戳的数据库。

    Abstract: A system and method for supporting concurrent message streams. The state machine is used for modeling a digital system having several states. The states represent messages in the digital system. Added to the state machine is a regressive state. The regressive state is connected to each of the states and all transitions between the states go through the regressive state. Also, queues are provided with the state machine to facilitate the concurrent message streams. A queue may be provided with each state so that if multiple message streams are at a single state, they may be stored in the queue provided with the state. Alternatively, a queue may be provided with each message stream so that each queue can keep track of the state at which the corresponding message stream is located.

    Abstract translation: 一种用于支持并发消息流的系统和方法。 状态机用于对具有多个状态的数字系统进行建模。 状态表示数字系统中的消息。 添加到状态机是一个回归状态。 回归状态连接到每个状态,并且状态之间的所有转换都经历回归状态。 此外,状态机提供队列以便于并发消息流。 可以为每个状态提供队列,使得如果多个消息流处于单个状态,则它们可以存储在与该状态一起提供的队列中。 或者,可以为每个消息流提供队列,使得每个队列可以跟踪对应的消息流所在的状态。
