摘要： The invention relates to a telecommunication network having IP packet-supporting capabilities, which includes a load distribution processing function, either centralized or distributed, by means of which a load distribution function may be applied to sets of paths between network nodes or sets of links of network trunks. The load distribution processing function handles different load distribution functions. Each of the different load distribution functions is associated to a different network input unit involved in the load distribution for a set of paths between network nodes or a set of trunk links. The invention also relates to a method of load distribution in a telecommunication network as summarized above.

摘要： A fast and scalable pattern making engine is presented. The engine represents variations on a Shift-And method capable of matching patterns in data streams having high speed data rates. In one aspect of the invention high speed is achieved by accessing the pattern RAM in parallel. In another aspect, the input is likened to TDM and individual slots or channels are accessed separately. The two aspects can also be combined to provide a scalable and high speed pattern matching engine. The engine is adaptable to streams of known length or more complex expressions such as regular expressions with arbitrary length.
摘要翻译： 提出了一种快速可扩展的模式制作引擎。 引擎表示能够匹配具有高速数据速率的数据流中的模式的Shift-And方法的变化。 在本发明的一个方面，通过并行访问图案RAM来实现高速度。 另一方面，输入比较为TDM，单独的槽或通道被单独访问。 这两个方面也可以组合起来提供可扩展的高速模式匹配引擎。 引擎适应于具有任意长度的已知长度或更复杂表达式的流，例如正则表达式。

摘要： A method and apparatus for frame-aware and pipelined hierarchical scheduling is described. In accordance with at least one embodiment of the invention, some or all schedulers of a communication node are associated with one or more storage devices that maintain values used by corresponding higher level schedulers to make scheduling decisions. Because of the nature of the scheduling decision flow and the potential to update registers in real-time, the scheduling arrangement can respond almost immediately to changes occurring at the input queues, which allows scheduling to be responsive to differing priorities of incoming cells. The nature of the scheduling decision flow also allows pipelined scheduling, in which scheduling of one or more additional cells can begin before scheduling of a first cell is completed.

摘要： An instruction memory shared by a number of processing units has a plurality of individually accessible sections. A software program in the instruction memory is distributed among the memory sections. Sequential parts of the software program are in sequential sections. The software program may have a common portion which is repeated in each of the memory sections. Arbiter logic may control which of the processing units accesses which of the memory sections in each memory access cycle.

摘要： In accordance with at least one embodiment of the present invention, a method and apparatus for scheduling traffic in a communications node is provided. Line cards request communication opportunities from a switch fabric. The switch fabric issues grants for such communication opportunities in response to specific requests. By dynamically adjusting usage of such communication opportunities corresponding to such grants among requests of differing priorities and/or latency criteria, embodiments of the present invention are able to provide increased capacity utilization of switching fabric bandwidth while maximizing adherence to priority requirements and/or latency criteria.

摘要： Viewers of video programming are provided with a low effort mechanism to access product or service information related to a program being viewed. This benefits the viewers by providing them with only desired information, and advertisers of the products and services, by focusing their messages on their target market. The availability of advertising or other supplemental information is provided to the viewer within the programming, at places that are time-marked when the programming is being developed or in real time. In response to receiving a request from the viewer for this information, any information associated with the time marker is delivered to the viewer.
摘要翻译： 提供视频节目观众的低功耗机制来访问与正在观看的节目相关的产品或服务信息。 通过将消息集中在目标市场上，这样可以让观众仅向他们提供所需信息，以及产品和服务的广告客户。 广告或其他补充信息的可用性在程序设计期间在编程正在开发或实时时刻被标记的地方提供给观众。 响应于从该观看者接收到关于该信息的请求，将与该时间标记相关联的任何信息传递给该观看者。
