Appl. No.:

11/088622

Inventors:

Deepali Apurva Brahmbhatt - Mountain View CA, US
Bryan Turner - Cary NC, US

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

G06F 15/16

US Classification:

709227, 709228, 709229

Abstract:

Apparatus and methods are disclosed for optimizing the transfer time of files in a peer-to-peer network. In disclosed embodiments, a requesting peer desires to transfer a file from a group of supplying peers creates a list of segments available of the file to be transferred available from each of the supplying peers, and orders the list in order of increasing segment size available. The supplying peers are then grouped based on available segments. Then, beginning with the group of supplying peers having the largest portion of the file to be transferred, the requesting peer assigning segments to transfer and a corresponding transfer time to each of the members of the group of supplying peers. The requesting peer then transfers in parallel the assigned segments from the group of supplying peers.

US Classification:

705 28, 328115, 707661, 707736

Abstract:

A system for storing and retrieving data associated with an identification of a RFID device. The invention receives data and a list of RFIDs associated with data. The system then stores the data in a memory and stores a record of an association by the data and each RFID. When the system receives a request for data that includes a RFID, the system searches for records of the associations and presents the data associated with the received RFID.

International Classification:

H04L 12/28
H04L 12/56

US Classification:

370401, 370402, 370404

Abstract:

Disclosed are methods and apparatus for methods and apparatus for facilitating a secure connection between a first and a second node in a computer network where one or both of the nodes may or may not reside behind a network address translation (NAT) enabled gateway. Embodiments of the present invention provide a seamless integration by providing a uniform solution for establishing secure connections, such as IPSEC, between two nodes irrespective of whether they are behind a NAT-enabled gateway or not. In general, a gateway is operable to receive a request from a remote host for a secure connection to a local host that within the home network of the gateway. The gateway then forwards this received request to a NAT traversal service. The NAT traversal service receives the request and then automatically sends an initiation message to set up a secure session, e. g. , performing authentication and exchanging keys.

International Classification:

H04W 4/00

US Classification:

370328, 4554261, 4555521, 4555531, 455446, 455447, 455448, 455449

Abstract:

According to one implementation of the present invention, a business logic application may function as a package tracking application to manage access to wireless access points in different WLANs along the route. A sensor node is initialized and configured with one or more connection parameter sets allowing it to associate with a given wireless network implemented by one or more access points. Before the sensor node disassociates with the wireless access point, the wireless access point transmits a new connection parameter set to the sensor node. This new connection parameter set may include a network ID for another wireless network. In one implementation, the sensor node re-initializes itself using the new connection parameter set information. This process may continue until the sensor node arrives at its final destination.

Abstract:

Methods, apparatuses, and systems directed to managing wireless node access to one or more wireless networks. According to one implementation of the present invention, a business logic application may function as a package tracking application to manage access to wireless access points in different WLANs along the route. A sensor node is initialized and configured with one or more connection parameter sets allowing it to associate with a given wireless network implemented by one or more access points. In one implementation, the sensor node is configured only to accept received wireless frames that it can properly decrypt using the currently-stored encryption key. Accordingly, until the sensor node comes within radio contact of a wireless access point or other wireless node configured with the same encryption key, it does not establish a wireless connection. When the sensor node and such a wireless access point associate, they may exchange encrypted information (e.g., data regarding the package) using an encryption key. Before the sensor node disassociates with the wireless access point, the wireless access point transmits a new connection parameter set to the sensor node. This new connection parameter set includes a network ID for another wireless network. In addition, the new connection parameter set also includes an encryption key and a frequency identifier. In one implementation, the sensor node re-initializes itself using the new connection parameter set information. This process may continue until the sensor node arrives at its final destination and, in this manner, the wireless networks with which the sensor node associates may be controlled.

International Classification:

H04N 5/76
H04Q 5/22

US Classification:

348231200, 348231300

Abstract:

A data file stored in a memory for storing an image with Radio Frequency Identification (RFID) device information. In this data file image data is stored in an image portion of the file. RFID device information for an RFID device that proximate the location shown in the image is then stored in a field in a metadata portion of the file.
