Abstract: 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.

Abstract: A network information apparatus (400), system (100) (200) and method for distributing network information in a multi-channel (MC) wireless network (100) (200), comprising a network information module (400) that implements inter-channel communication of network information in an MC network according to a pre-determined network information sharing procedure and keeping an own cache (401) of each node refreshed and free of out-of-date information, and, for an active proxy-based sharing procedure thereof only, adapting to changes in node/channel associations, suppressing duplicate inter-channel information, and synchronizing own clocks (404) of each node.

Abstract: 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.

Abstract: Apparatus and techniques for automatically allocating storage space among classes of applications and/or users in a shared storage environment are proposed. In one illustrative embodiment, such apparatus includes: (i) a plurality of per-class controllers, each per-class controller being operative to determine a cache space allocation for its corresponding class based on a current measured hit rate and a current cache space allocation for its corresponding class; and (ii) a contention resolver coupled to the plurality of per-class controllers and operative to resolve cache space allocation in response to conflicting requests from at least two of the per-class controllers.
