摘要： The invention is an intelligent traffic redirection system that does global load balancing. It can be used in any situation where an end-user requires access to a replicated resource. The method directs end-users to the appropriate replica so that the route to the replica is good from a network standpoint and the replica is not overloaded. The technique preferably uses a Domain Name Service (DNS) to provide IP addresses for the appropriate replica. The most common use is to direct traffic to a mirrored web site.

摘要： A replication process to provide fault tolerance for a streaming signal in a computer network. In one embodiment, the original or source signal is sent to several splitters which, in turn, each make copies of the signal and send the copies into a second layer of devices, which are referred to as “concentrators.” A given concentrator receives as input one or more copies of the source signal. In a preferred embodiment, a given concentrator receives two copies of the source signal from at least two different splitters. The concentrators process the incoming streaming signal copies, for example, by merging them into a single or composite copy of the original source signal according to a given processing algorithm. The output of a given concentrator may then be fed into a splitter, with the process then being repeated if desired to make an arbitrary large number of copies of the signal. At the end of the replication process, the output of a splitter or a concentrator is fed directly or indirectly to an end user. The replication process is fault-tolerant, and thus the end user's signal is not interrupted regardless of signal or equipment problems within the distribution mechanism.

摘要翻译：为计算机网络中的流信号提供容错的复制过程。在一个实施例中，原始或源信号被发送到多个分离器，这些分离器又分别进行信号的副本并将副本发送到被称为“集中器”的第二层设备。给定的集中器作为输入接收源信号的一个或多个副本。在优选实施例中，给定的集中器从至少两个不同的分配器接收源信号的两个拷贝。集中器例如通过根据给定的处理算法将它们合并成原始信号源的单个或复合副本来处理输入的流传输信号副本。然后可以将给定的聚光器的输出馈送到分离器中，如果需要，则重复该过程以产生任意大量的信号。在复制过程结束时，分离器或集中器的输出被直接或间接地馈送给终端用户。复制过程是容错的，因此无论分发机制中的信号或设备问题如何，最终用户的信号都不会中断。

摘要： Third party cache appliances are configured into a content delivery service to enable such devices to cache and serve content that has been tagged for delivery by the service. The invention enables the content delivery service to extend the reach of its network while taking advantage of high performance, off-the-shelf cache appliances. If the third party caches comprise part of a third party content delivery network, the interconnection of caches to the CDS according to the present invention enables the CDS and the third party network to share responsibility for delivering the content. To facilitate such “content peering,” the CDS may also include a traffic analysis mechanism to provide the third party network with preferably real-time data identifying the content delivered by the CDS from the third party caches. The CDS may also include a logging mechanism to generate appropriate billing and reporting of the third party content that is delivered from the cache appliances that have been joined into the CDS.

In one embodiment, the original or source signal is sent to several splitters which, in turn, each make copies of the signal and send the copies into a second layer of devices, which are referred to as “concentrators.” A given concentrator receives as input one or more copies of the source signal.
