Filed:

Nov 2, 2005

Appl. No.:

11/265776

Inventors:

Kent Johnson - Bowie MD, US
John C. Schultz - Saline MI, US
Csilla B. Ujvary - Westland MI, US

Assignee:

GM Global Technology Operations, Inc. - Detroit MI

International Classification:

F04B 41/06

US Classification:

417 2, 41742314, 184 63

Abstract:

The apparatus of the present invention provides a compact dual-pump assembly for an automotive transmission. The dual-pump assembly preferably includes a housing having a valve assembly mounted thereto. The valve assembly includes a shuttle valve disposed in fluid communication with a pressure regulating valve. An on-axis pump is mounted to the housing in fluid communication with the shuttle valve and the pressure regulating valve. An off-axis pump in fluid communication with the shuttle valve is mounted to the housing in close proximity to the on-axis pump such that the dual-pump assembly is compact.

US Classification:

370252, 370389, 714748

Abstract:

The present invention relates to a packet recovery method for packets communicated between sender and receiver nodes of an overlay network that runs over an underlying IP network. The present invention executes a packet recovery process at a receiver node upon satisfaction of a packet recovery condition that is associated with meeting a deadline driven criteria for a transmitted packet. The packet recovery process associates N number of scheduled times with N requests for retransmission of the transmitted packet. At least one of the N scheduled times includes a receiver waiting time. At each N scheduled time, a request for retransmission of the transmitted packet is transmitted to a source node. A packet retransmission process at the sender node is executed upon the first receipt of a request for retransmission of the transmitted packet. In one embodiment, the packet retransmission process retransmits the transmitted packet to the receiver node at M number of scheduled times, where the N and M are non-zero positive integers and at least one of the N or M number of scheduled times is greater than one.

International Classification:

H04L 12/28

US Classification:

370390, 37039531, 709238

Abstract:

A routing system and method for flows within a network provides multicast flow transport for one or more groups. Transit routers comprising processing units that run overlay processes route one or more flows based on overlay group identifiers. Access nodes issue requests for overlay groups in order to receive flows from the transit routers. The overlay processes utilize a mapping service that maps overlay group identifiers to native multicast group identifiers. A control channel between the access nodes and transit routers is used for communicating access nodes requests, overlay group identifiers, and native multicast group identifiers.

International Classification:

H04L 12/939

US Classification:

370216

Abstract:

A packet recovery transmits N requests for retransmission of the transmitted packet to the sender node at N scheduled times upon determining satisfaction of a packet recovery condition associated with a transmitted packet from a sender node at a receiver node. At least one of the N scheduled times includes a receiver waiting time. M retransmissions of the transmitted packet from sender node at M scheduled times is performed upon the first receipt of a request for retransmission of the transmitted packet. At least one of the M scheduled times includes a sender waiting time. N and M are non-zero positive integers, and at least one of N or M is greater than one.
