摘要： A system for, and method of, determining a physical topology of a network having multiple subnets. In one embodiment, the system includes: (1) a skeleton path initializer that uses addressing information from elements in the network to develop a collection of skeleton paths of direct physical connections between labeled ones of the elements, the skeleton paths traversing multiple of the subnets and (2) a skeleton path refiner, coupled to the skeleton path initializer, that refines the collection by inferring, from the direct physical connections and path constraints derived therefrom, other physical connections in the skeleton paths involving unlabeled ones of the elements.

摘要： A power aware Point-Of-Presence design and auto-configuration method is disclosed for configuring which network elements within a point-of-presence are powered so as to accommodate anticipated traffic while minimizing power consumption. The IP power aware Point-Of-Presence design and auto-configuration method includes a set of activation thresholds associated with each port in the Point-of-Presence that indicates that the port should be activated when the traffic demand exceeds the threshold. The power aware Point-Of-Presence design and auto-configuration method is particularly useful for providing a configuration which accounts for both external and internal link traffic demand and has the further advantage of ordering the port activation such that only a minimum number of activation and deactivation operations to satisfy a new demand is required. This property is advantageous for limiting the routing instabilities caused by topological changes in response to varying demand.
摘要翻译：公开了一种功率感知的现场设计和自动配置方法，用于配置在存在点内的哪些网络元件被供电以便在最小化功耗的同时适应预期的业务。 IP功率感知的现场设计和自动配置方法包括与点状态中的每个端口相关联的一组激活阈值，其指示当业务需求超过阈值时该端口应被激活。功率感知的现场设计和自动配置方法对于提供考虑外部和内部链路业务需求的配置特别有用，并且具有排序端口激活的另外的优点，使得只有最小数量的激活和需要停用操作以满足新的需求。该属性有利于限制由响应于不同需求的拓扑变化引起的路由不稳定性。

摘要： The number of directional antennas and associated radios needed to ensure a nomadic wireless mesh network (NWMN) remains operational in the event of node or link failures, while minimizing delay and other unwanted effects, may be determined using novel methods and devices. Such a determination may reduce the number of antennas and radios a service or network provider normally uses, thus reducing its costs.

摘要： Unique identifiers are assigned to sets of adjacent access points in a wireless, local area network (WLAN). Thereafter, a unique identifier may be forwarded to a mobile device which uses the identifier to associate itself with one of the adjacent access points. Associating a mobile device with an adjacent access point using unique identifiers allows a WLAN to meet its load balancing objectives.
