摘要： A media source sends media packets over a first media path. Repair packets are encoded from the media source packets and sent over a second different media path. Sending the source packets and repair packet over different media paths is referred to as Forward Error Correction (FEC) spatial diversity and reduces the amount of repair packet overhead required for repairing the media source packets in case of a network outage or packet loss. To provide load balancing, a first set of media streams may be sent over the first media path and a second set of media streams may be sent over the second media path. If a fault is detected on one of the media paths, then the repair packets may no longer be transmitted and the one or more media streams from the disabled media path are transmitted over the working media path.
摘要翻译：媒体源通过第一媒体路径发送媒体包。修复数据包是从媒体源数据包编码的，并通过第二个不同的媒体路径发送。通过不同的媒体路径发送源数据包和修复数据包称为前向纠错（FEC）空间分集，并减少在网络中断或丢包的情况下修复媒体源数据包所需的修复数据包开销的数量。为了提供负载平衡，可以通过第一媒体路径发送第一组媒体流，并且可以在第二媒体路径上发送第二组媒体流。如果在其中一个媒体路径上检测到故障，则修复分组可能不再被发送，并且来自被禁用媒体路径的一个或多个媒体流在工作媒体路径上传输。

摘要： A system and/or method to determine the location within a building of an apparatus, such as a personal computer, coupled to a computer network. A communication facility of the apparatus is configured to source and sink messages in the computer network via at least one network port coupled to the computer network. A radio frequency (RF) receiver of the apparatus is configured to receive beacon signals transmitted by a plurality of base stations, the base stations located in the building, each beacon signal encoded with location information descriptive of the location of one of the base stations. Also, a location determination engine of the apparatus is configured to compute a location of the apparatus based on the location information encoded in the beacon signals, the computed location being a point within the building.

摘要： A distributed digital data processing system includes a plurality of nodes which communicate over a network. A node maintains one or more objects, each of which may be a file, that is, an addressable unit in the system, such as a program, database, text file, or the like, or a directory which may contain one or more files or other directories. One node maintains a naming service which associates each object in the system with one or more protocol towers. Each protocol tower identifies the object name and a series of entries each identifying a name for each of the protocol layers, along with the communications parameters and address information, to be used in communicating with the object. When a node requires access to an object maintained by another node, it first retrieves from the naming service the protocol towers for the object. The node also maintains a tower identifying the names of each of the protocols over which it can communicate. The node then compares the protocol names in the retrieved protocol towers with the protocol names over which it can communicate. If the protocol names in a retrieved tower match the protocol names in the node's tower, the node uses the communications parameters and address information in future communications with the object. If the node is unable to identify a retrieved protocol tower which matches its supported tower or towers, it is unable to communicate with the object.
摘要翻译：分布式数字数据处理系统包括通过网络进行通信的多个节点。节点维护一个或多个对象，每个对象可以是文件，即系统中的可寻址单元，诸如程序，数据库，文本文件等，或者可以包含一个或多个文件的目录或其他目录。一个节点维护命名服务，将系统中的每个对象与一个或多个协议塔相关联。每个协议塔标识对象名称和一系列条目，每个条目标识每个协议层的名称，以及要与对象进行通信的通信参数和地址信息。当节点需要访问由另一个节点维护的对象时，它首先从命名服务检索对象的协议塔。节点还维护一个塔，标识可以与之通信的每个协议的名称。然后，节点将检索到的协议塔中的协议名称与可以通信的协议名称进行比较。如果检索到的塔中的协议名称与节点塔中的协议名称相匹配，节点将在与对象的通信中使用通信参数和地址信息。如果节点无法识别与其支持的塔或塔相匹配的检索协议塔，则无法与对象进行通信。

摘要： A router, switch, or other network node generates reports that contain packet level statistics and other information for a monitored media stream. The media stream reports reduce the amount of bandwidth typically required for sending monitored media stream information back to a central analysis device. However the computation of other media stream analytics, such as long term statistical averaging or quality metric computation, is performed by the central analysis device to remove some of the processing burden from the individual network nodes.

摘要： A technique enables resources to be shared among data flows that may have different senders (sources) and/or different receivers (destinations) in a data network. Identifiers are associated with data flows and used to indicate whether resources may be shared between data flows. The identifiers are carried in signaling messages used to reserve resources for data flows. An existing data flow that is associated with an identifier that matches an identifier associated with a new data flow is allowed to share resources its resources with the new data flow.

摘要： A switch detects port failures and identifies a MAC address associated with the port failure. The switch then sends a failure notification message to other ports on the switch that identifies the MAC address associated with the port failure. The network processing devices on the other ports use the failure notification message to quickly determine if routes need to be reconfigured around an adjacency on the switch.

摘要： A technique is provided for one or more network nodes to deterministically select data flows to preempt. In particular, each node employs a set of predefined rules which instructs the node as to which existing data flow should be preempted in order to admit a new high-priority data flow. The rules are precisely defined and are common to all nodes configured in accordance with the present invention. Illustratively, a network node not only selects a data flow to preempt, but additionally may identify other “fate sharing” data flows that may be preempted. As used herein, a group of data flows has a fate-sharing relationship if the application instance(s) containing the data flows functions adequately only when all the fate-shared flows are operational. In a first illustrative embodiment, after a data flow in a fate-sharing group is preempted, network nodes may safely tear down the group's remaining data flows. In a second illustrative embodiment, when a data flow is preempted, all its fate-shared data flows are marked as being “at risk.” Because the at-risk flows are not immediately torn down, it is less likely that resources allocated for the at-risk flows may be freed then subsequently used to establish relatively lower-priority data flows instead of relatively higher-priority data flows.
摘要翻译：为一个或多个网络节点提供一种确定性地选择要抢占的数据流的技术。特别地，每个节点采用一组预定义的规则，其指示节点应该抢占哪个现有数据流，以便允许新的高优先级数据流。这些规则被精确定义，并且对于根据本发明配置的所有节点是共同的。示例性地，网络节点不仅选择要抢占的数据流，而且可以标识可被抢占的其他“命运共享”数据流。如本文所使用的，如果包含数据流的应用实例仅在所有命运共享流可操作时才起作用，则一组数据流具有命运共享关系。在第一说明性实施例中，在命运共享组中的数据流被抢占之后，网络节点可以安全地拆除该组的剩余数据流。在第二个说明性实施例中，当数据流被抢占时，其所有命运共享数据流被标记为处于“处于危险之中”。由于风险流动并没有立即被拆除，所以分配给风险流动的资源可能会被释放，随后被用于建立相对较低优先级的数据流而不是相对较高优先级的数据流。
