摘要： An exemplary embodiment of the invention is a method of detecting network elements in an optical communications network. The method includes an initiating network element generating a neighbor discovery message including a requested hierarchy level at which neighbor discovery is requested and transmitting the neighbor discovery message downstream along the optical communications network. A downstream network element receives the neighbor discovery message, determines if the downstream network element operates at the requested hierarchy level. The downstream network element generates a responding neighbor discovery message if the downstream network element operates at the requested hierarchy level and transmits the responding neighbor discovery message to the initiating network element. Alternate embodiments include a system and storage medium for implementing the method.

摘要： The benefits of Transport Control Protocol (TCP) over Available Bit Rate (ABR) Service of an Asynchronous Transfer Mode (ATM) network is extended to the entire TCP connection by intercepting and modifying TCP congestion control information in accordance with resource information associated with the TCP connection. An algorithm calculates a new advertised window size based on various network resource parameters, such as ABR. The advertised window is adjusted if the newly calculated window size is smaller than the advertised window size. By adjusting the TCP window, the normal extreme fluctuations of the TCP window are avoided.

摘要： A method and apparatus for efficiently transporting DS-X traffic in packet form over an ATM or other packet network. Specifically, virtual connection or slot provisioning and/or cell concentration techniques are used to compact the amount of DS-X traffic broadcast between communications system devices such as the access mux and the communications switch and spare bandwidth. In provisioning, a configured DS-X loading of an end node supporting DS-X traffic is ascertained. In turn, a minimum number of virtual connections for bearing packetized DS-X traffic are established, either at communications system configuration or as needed. In concentration processing, a dynamic association between the virtual connections and the DS-X traffic is established, typically on a per frame basis. Only those digital channels entering the node within a given time frame which actually bear DS-X traffic will be assigned a slot within packet. Concentration may be augmented by provisioning to further reduce bandwidth requirements. In other disclosed aspects, permanent virtual channels or PNNI soft permanent virtual connections may be used for the virtual connections where ATM is chosen as the transport protocol.
摘要翻译：一种用于通过ATM或其他分组网络以分组形式有效地传送DS-X业务的方法和装置。具体地，使用虚拟连接或时隙供应和/或小区集中技术来压缩诸如接入复用器和通信交换机的通信系统设备之间的DS-X业务广播量以及备用带宽。在配置中，确定支持DS-X流量的端点节点的配置的DS-X加载。反过来，在通信系统配置或根据需要建立用于承载分组化DS-X流量的最小数量的虚拟连接。在集中处理中，建立虚拟连接与DS-X流量之间的动态关联，通常在每帧的基础上。只有在给定时间段内进入节点的那些实际承载DS-X流量的数字信道才会在分组内分配一个时隙。可以通过配置来增加集中度，以进一步减少带宽需求。在其他公开的方面中，永久虚拟信道或PNNI软永久虚拟连接可以用于选择ATM作为传输协议的虚拟连接。

摘要： Fairness is provided among network sessions contending for available bit rate (ABR) service in an asynchronous transfer mode network by determining congestion information on a per port basis. ABR cells are monitored to determine which rate information per outgoing port based on ABR cells leaving a switch. Using the ABR per port rate, the available capacity, and the input rate to output queues, a link congestion parameter (LCP) is determined. Resource Management (RM) cells traveling through the switch are monitored to determine whether the new LCP is lower than the explicit rate (ER) field in RM cell. If the new LCP is lower, the new LCP is stuffed into the RM cell. When the sender receives the LCP value, the sender output rate is adjusted based on the LCP. Because LCP is determined based on per port traffic flow, fairness is provided among session competing for available ABR capacity.
摘要翻译：通过在每个端口的基础上确定拥塞信息，在异步传输模式网络中针对可用比特率（ABR）服务的网络会话中提供公平性。监控ABR单元以基于离开交换机的ABR单元确定每个输出端口的哪些速率信息。使用每个端口速率的ABR，可用容量和输出队列的输入速率，确定链路拥塞参数（LCP）。监视通过交换机行进的资源管理（RM）单元以确定新的LCP是否低于RM单元中的显式速率（ER）字段。如果新的LCP较低，则将新的LCP填充到RM单元中。发送方收到LCP值后，根据LCP调整发送方输出速率。由于LCP是根据每个端口流量确定的，所以在会话竞争中获得可用的ABR容量之间提供公平性。
