Patent number: 9445418Abstract: In one embodiment, a transmitting node may be configured to transmit a wireless advertisement frame over a computer network, wherein the frame includes a source address of a reachable node being advertised, a destination address to which the reachable node is to be advertised, a transmitter address of the transmitting node, and a receiver address of a wireless access point to which the wireless advertisement frame is to be received. Also, the wireless access point may be configured to receive the wireless advertisement frame from the network, and in response, transmit a reflected wireless advertisement frame having the source address of the reachable node, the destination address to which the reachable node is to be advertised, a transmitter address of the access point, and a receiver address that indicates the reflected frame is to be accepted by any appropriate receiver excluding the transmitting node.Type: GrantFiled: September 15, 2015Date of Patent: September 13, 2016Assignee: CISCO TECHNOLOGY, INC.Inventors: Norman W. Finn, Robert O'Hara, Rohit Suri, Joshua Broch

Patent number: 8774077Abstract: In one embodiment, a wireless access point receives a wireless advertisement frame having a source address field that indicates a reachable node being advertised, a destination address field that indicates a destination to which the reachable node is to be advertised, a transmitter address field that indicates a transmitting node from which the wireless advertisement frame is received, and a receiver address field that indicates the access point. The wireless access point then transmits a reflected wireless advertisement frame having a source address field that indicates the reachable node, a destination address field that indicates the destination, a transmitter address field that indicates the wireless access point, and a receiver address field that indicates both a plurality of receivers the reflected wireless advertisement frame is to be accepted by, and a node that is to be excluded from accepting the reflected wireless advertisement frame.Type: GrantFiled: August 20, 2012Date of Patent: July 8, 2014Assignee: Cisco Technology, Inc.Inventors: Norman W.

Publication number: 20050107097Abstract: Methods, systems and data structure for storing and managing information in a wireless network are described wherein fixed resources in the system are stored in a database in a hierarchical directory structure according to the location of each fixed resource. Each level of the directory structure represents a geographical area in which a fixed resource is located. A mobile user submits a query for the location of the nearest fixed resource having certain properties. The system determines the location of the mobile user and then searches the database for the requested fixed resource that is nearest to the mobile user. When the fixed resource is identified, data regarding its location is transmitted to the mobile user. In addition, specific directions as to how to get to the location of the fixed resource from the location of the mobile user may be provided.Type: ApplicationFiled: October 25, 2004Publication date: May 19, 2005Applicant: Microsoft CorporationInventors: Paramvir Bahl, Joshua Broch
