Patent number: 8787157Abstract: One exemplary embodiment is directed to a method for deep space communication. The method comprises generating a first packet, assigning a first priority level to the first packet, and selecting at least one communication link from a plurality of communication links for transmission of the first packet. Selecting is a function of a rule specifying which one or more communication links a packet of the first priority level is to be transmitted over. The method also includes transmitting the first packet over the at least one communication link.Type: GrantFiled: June 23, 2011Date of Patent: July 22, 2014Assignee: Honeywell International Inc.Inventors: Ronald Rundquist, Pablo Bandera, Yunjung Yi, Haowei Bai

Patent number: 8077603Abstract: In one embodiment, a node comprises a plurality of IEEE 1394 subnet interfaces for communicating over a plurality of IEEE 1394 buses. Each of the plurality of IEEE 1394 subnet interfaces comprises a respective IEEE 1394 physical layer and IEEE 1394 link layer for communicating over a respective one of the plurality of IEEE 1394 buses. At least the IEEE 1394 physical layers for the plurality of subnet interfaces do not share hardware. The node further comprises at least one programmable processor that executes software that comprises common network layer functionality that interacts with all of the plurality of IEEE 1394 subnet interfaces and routes IEEE 1394 data packets among the plurality of IEEE 1394 buses.Type: GrantFiled: October 27, 2005Date of Patent: December 13, 2011Assignee: Honeywell International Inc.Inventors: Haowei Bai, Brian VanVoorst, Allalaghatta Pavan, Vicraj T.

Patent number: 7990898Abstract: In one embodiment, a system comprises a plurality of nodes and an IEEE 1394 bus. Each of the plurality of nodes comprises at least one IEEE 1394 interface for communicating over the IEEE 1394 bus. The plurality of nodes communicates over the IEEE 1394 bus in accordance with a rooted, half-binary tree topology. In another embodiment, a node comprises an IEEE 1394 interface to communicate over an IEEE 1394 bus. The node encapsulates logical data packets into IEEE 1394 data packets and maps a traffic class associated with each logical data packet to an IEEE 1394 class of service for the IEEE 1394 data packet into which that logical data packet is encapsulated.Type: GrantFiled: October 27, 2005Date of Patent: August 2, 2011Assignee: Honeywell International Inc.Inventors: Haowei Bai, Allalaghatta Pavan, Brian VanVoorst, Vicraj T.

Publication number: 20080239948Abstract: Methods and apparatus are provided to improve data throughput in a wireless, wireline or a combination wireless and wireline communication system. A congestion control manager selects between an assumption based congestion control algorithm and a speculation based congestion control algorithm. The selected algorithm generates data recovery instructions including instructions for resizing, or not, congestion window sizing for the communication gateways. By making the selection between the assumption based congestion control algorithm and the speculation based congestion control algorithm based upon network information, data recovery and throughput is optimized for networks having lossy data links.Type: ApplicationFiled: March 28, 2007Publication date: October 2, 2008Applicant: HONEYWELL INTERNATIONAL, INC.Inventors: Haowei Bai, David J.

Publication number: 20080239953Abstract: Methods and apparatus are provided to reduce data congestion and thus improve data throughput in gateways used in a wireless, wireline or a combination wireless and wireline communication system. The congestion management system optimally resizes, or not, congestion window (or buffer) sizing and threshold for the communication gateways based upon mathematical models. Application of the inventive congestion management method optimizes data recovery and throughput in communication networks, particularly those networks having lossy data links.Type: ApplicationFiled: March 28, 2007Publication date: October 2, 2008Applicant: HONEYWELL INTERNATIONAL, INC.Inventors: Haowei Bai, David J.
