Appl. No.:

13/214511

Inventors:

Igor Ryshakov - Mountain View CA, US

International Classification:

H04N 7/06
H04L 12/66
H04L 1/22

US Classification:

370221, 370401, 370352, 725109, 370228

Abstract:

In a network environment, the Quality of Service becomes an important issue particularly for applications involved with real-time multimedia streaming. Any transmission failure may cause service disruption and the failure has to be quickly recovered to minimize the impact. A unified home networking standard based on existing media in home has been developed to meet the increasing demand for bandwidth, reliability and availability. However, the fault tolerant protocol adopted by the home networking standard is based on an advanced selective ARQ (Automatic Retransmission Request) protocol which may take hundreds of millisecond to establish a backup channel. Alternatively, a hot standby backup channel has to be used to achieve quick switch without data loss at the expense of increased power consumption by the hot standby channel. The present invention discloses a quick-switch modem that can quickly switch from a primary channel to a backup channel upon detection of transmission failure. The quick-switch modem contains an additional interface between the modems for the primary channel and the secondary channel. In order to achieve quick failure detection and data re-route, the quick-switch modem relies on lower layers of the network link to facilitate failure detection and data re-route. Consequently, the switching time is substantially reduced without the need of hot standby. Alternatively, the quick-switch modem can be configured for load sharing to enhance overall available bandwidth.

Assignee:

Cubic Corporation - San Diego CA

International Classification:

H04W 52/02

US Classification:

370311

Abstract:

Techniques are disclosed for reducing the amount of overhead transmitted in ad-hoc low-power wireless networks. Embodiments generally include aggregating a plurality of data packets and prepending and appending each with associated data. The plurality of data packets then can be inserted into a single data frame, or packet for transmission. Gaps may be inserted between the data packets for timing synchronization and/or other purposes.

Georgi Danielyan - Yerevan, AM

Assignee:

Cubic Corporation - San Diego CA

International Classification:

G06F 15/16

US Classification:

709229

Abstract:

Embodiments of methods and devices are disclosed for enabling network devices to join a network. These embodiments generally include a first network device, which is joined to the network, sending authentication information. If the authentication information is determined as valid by a second network device, the second network device sends a join request toward the first network device. During or after the joining process, the first and second network devices can share scheduling information. These embodiments enable a network to have additional security while consuming low amounts of power.

International Classification:

H04W 24/04
H04W 40/10
H04W 40/14

US Classification:

370219

Abstract:

Methods of telecommunicating and systems configured to perform the methods are disclosed. In some embodiments, the methods include establishing a primary communications link, determining that a backup communications link is to be established, and determining a plurality of candidate network nodes. The method also includes selecting one of the candidate network nodes with which to establish the backup communications link, where the selected candidate network node is selected based at least in part on the selected candidate network node being in a foreign network, establishing the backup communications link with a selected candidate network node, and communicating using the backup communications link.

International Classification:

H04W 76/02
H04W 84/18

US Classification:

370328

Abstract:

Techniques are disclosed for specifying and enforcing connections in a network. Embodiments generally include a network device that maintains a data structure that identifies preferred nodes. The data structure includes entries associated with preferred nodes. Connections are established and enforced based on the entries of the data structure. The data structure may be updated and modified allowing network and node reconfiguration.
