    • The disclosure presents techniques for merging multiple data flows in a network such as a Passive Optical Network (PON). The PON comprises an interface module and network nodes connected to the interface module via an optical fiber link. Each network node further serves client devices. The client devices request multiple data flows, requiring the interface module to serve multiple data flows to a network node for delivery to the devices. The interface module merges received data flows to permit multiple flows to be processed by a single segmentation and reassembly (SAR) engine, reducing hardware cost and complexity within the node. However, subunits associated with different data flows within a merged data flow are not interleaved with one another. Instead, the subunits associated with an original unit of information are transmitted contiguously within the merged data flow, facilitating identification and reassembly of the subunits for a particular microflow.
    • 本公开提供了用于在诸如无源光网络(PON)的网络中合并多个数据流的技术。 PON包括接口模块和经由光纤链路连接到接口模块的网络节点。 每个网络节点还为客户端设备提供服务。 客户端设备请求多个数据流,要求接口模块向网络节点提供多个数据流,以传送到设备。 接口模块将接收的数据流合并,以允许通过单个分段和重组(SAR)引擎处理多个流,从而降低节点内的硬件成本和复杂度。 然而,与合并的数据流内的不同数据流相关联的子单元不会彼此交错。 相反,与原始信息单元相关联的子单元在合并的数据流内连续传输,有助于识别和重新组装特定微流的子单元。

    • A technique for providing real-time multimedia conferencing services with guaranteed performance, in a hybrid networking environment, by interconnecting cable modem-based premises networks via hybrid fiber coaxial (HFC) access networks and an ATM wide area network is disclosed. The ATM wide area network may be divided into a plurality of access network domains and one backbone network domain to provide efficient and intelligent multimedia conferencing services. Each ATM access network domain has one cable modem server as well as access multimedia bridge server. There is only one central network server and one central multimedia bridge server within the backbone network domain. Each cable modem server located in an ATM access network domain maintains necessary information of how the cable network bandwidth is used by existing calls, and will be allocated when new multimedia conference calls are initiated, in accordance with desired priority and performance levels.
    • 公开了一种在混合网络环境中通过混合光纤同轴(HFC)接入网络和ATM广域网互联基于电缆调制解调器的房屋网络来提供具有保证性能的实时多媒体会议业务的技术。 ATM广域网可以分为多个接入网域和一个骨干网域,以提供高效智能的多媒体会议业务。 每个ATM接入网域都有一个电缆调制解调器服务器以及接入多媒体桥服务器。 骨干网域内只有一台中央网络服务器和一台中央多媒体网桥服务器。 位于ATM接入网域中的每个电缆调制解调器服务器保持有关现有呼叫如何使用有线网络带宽的必要信息,并且将根据期望的优先级和性能水平在新的多媒体会议呼叫被启动时被分配。
