摘要： A method and system for detecting and correcting invalid network paths in a network having a plurality of routers and a set of global invariant rules imbedded in the network including querying a subset of a routing table data structure defining network paths wherein said subset includes a plurality of routing table entries and comparing a network routing table entry with an earlier network routing table entry for the same node. The method and system also includes detecting inconsistencies between the newer network routing table entry and the earlier network routing table entry, and invalidating the network entries of the older network routing table that are inconsistent with the newer entries. The method and system also includes reconstructing the routing structure by replacing the invalidated network routing table entries with new routing table entries that minimize violation of the invariant protocols.

摘要： A distributed coordination of a wireless network operating on different channels is provided by dispatching a device on each ‘home’ channel to regularly visit other ‘foreign’ channels to propagate and listen to broadcast information on these channels. The information in the broadcast packets transmitted on the home channel is relayed to the devices on the foreign channels by the dispatched device, as a ‘proxy device’ that operates on behalf of the other devices in the home channel. In a preferred embodiment, various aspects of this proxy process are optimized to reduce overhead and delays. Each channel is configured to distinguish home devices from foreign devices, to avoid contention between home and foreign devices. Acquired beacon slots on foreign channels are reserved to facilitate returning proxy devices. At the home channel, an anchor device alerts other devices of the proxy device's temporary absence and preserves the proxy device's beacon slot on the home channel.
摘要翻译：通过在每个“家庭”频道上发送设备来定期访问其他“外部”频道来传播和收听这些频道上的广播信息，来提供在不同频道上操作的无线网络的分布式协调。在归属信道上发送的广播分组中的信息被分配的设备中继到外部信道上的设备，作为代表家庭信道中的其他设备操作的“代理设备”。在优选实施例中，优化该代理过程的各个方面以减少开销和延迟。每个通道被配置为将家用设备与外部设备区分开，以避免家庭和外部设备之间的争用。保留在外国频道上获取的信标插槽，以方便退回代理设备。在家庭通道，锚设备向其他设备通知代理设备暂时不存在，并在家庭通道上保留代理设备的信标时隙。
