Internet Communication System And Method With Asymmetric Terrestrial And Satellite Links

View page
US Patent:
6820132, Nov 16, 2004
Filed:
Mar 11, 2000
Appl. No.:
09/523772
Inventors:
David S. Puente - Olney MD
Burt H. Liebowitz - North Bethesda MD
Thomas Jacobson - Gordon WI
Assignee:
Loral CyberStar, Inc. - Rockville MD
International Classification:
G06F 1300
US Classification:
709238, 709203, 709217
Abstract:
Low-cost, high performance access is provided to an Internet service provider (ISP) not convenient to a high volume Internet exchange point using a flexible hybrid terrestrial-satellite Internet communications system and method. The system and method provide high volume connectivity between an Internet service provider (ISP) and a remote customer site that generates a request for content to be supplied by the ISP. In an exemplary system, a first gateway processes a request for content generated at the remote customer site and routes the request. A second gateway processes the request routed by the first gateway to route the request to the content provider. One or more satellites are used to transmit requested content supplied by the ISP to the remote customer site. An exemplary method comprises the steps of generating a request for content at the remote customer site, processing the request for content to route it to the content provider, and transmitting requested content supplied by the ISP to the remote customer site by way of one or more satellites. The request for content may be routed by way of a terrestrial communications link, such the Internet, or may be routed to the ISP by way of the one or more satellites.

Usage-Based Billing System For Full Mesh Multimedia Satellite Network

View page
US Patent:
57577846, May 26, 1998
Filed:
Jan 4, 1996
Appl. No.:
8/582750
Inventors:
Burt Liebowitz - North Bethesda MD
Steven Sweeney - Silver Spring MD
Assignee:
Orion Atlantic, L.P. - Rockville MD
International Classification:
H04B 7212
H04M 1532
US Classification:
370321
Abstract:
A satellite communications system is provided for full mesh connectivity between a number of earth terminals via a satellite link. The earth terminals are connected to user access devices to receive and transmit voice, video and data and are operable to generate bursts to transmit user data via a satellite, and to process data received from the satellite and transmit it to the addressed user access devices. The terminals each comprise a programmable computing device which organizes bursts in at least one of a plurality of slots constituting a time division multiple access frame in accordance with a burst plan. Billing is based on usage and committed information rates. Data and voice can be billed on one invoice.

Full Mesh Satellite-Based Multimedia Networking System

US Patent:
58125450, Sep 22, 1998
Filed:
Jan 23, 1996
Appl. No.:
8/589255
Inventors:
Burt Liebowitz - North Bethesda MD
Steven Sweeney - Silver Spring MD
Heinrich Arens - Oberteuringen, DE
Franz Thaller - Bermatingen, DE
Assignee:
Orion Atlantic, L.P. - Rockville MD
Nortel Dasa Network Systems GmbH & Co.
International Classification:
H04J 316
US Classification:
370337
Abstract:
A satellite communications system is provided for full mesh connectivity between a number of earth terminals via a satellite link. The earth terminals are connected to user access devices to receive and transmit voice, video and data and are operable to generate bursts to transmit user data via a satellite, and to process data received from the satellite and transmit it to the addressed user access devices. The terminals each comprise a programmable computing device which prioritizes data into bursts using a fragmentation protocol. The programmable computing device also organizes bursts in at least one of a plurality of slots constituting a time division multiple access frame in accordance with a burst plan. Each terminal has access to a guaranteed number of the slots. The allocation of the remaining slots among the terminals varies dynamically to increase or decrease the burst transmission rates of the terminals as needed.

Internet Communication System And Method With Asymmetric Terrestrial And Satellite Links

US Patent:
60385944, Mar 14, 2000
Filed:
Feb 2, 1998
Appl. No.:
9/017142
Inventors:
David S. Puente - Olney MD
Burt H. Liebowitz - North Bethesda MD
Thomas Jacobson - Gordon WI
Assignee:
Loral CyberStar, Inc. - Rockville MD
International Classification:
G06F 1300
US Classification:
709217
Abstract:
Low-cost, high performance access is provided to a group of Internet service providers (ISPs) not convenient to a high volume Internet exchange point through a flexible hybrid terrestrial-satellite Internet communication system. Asymmetric hybrid circuits, that combine satellite and terrestrial backbone technologies, are used to handle asymmetry resulting from low volume requests and high volume responses. A user request is coupled via routers and servers to a point of presence (POP) on a group ISP backbone network. The ISP's backbone couples ISP's POPs to a terrestrial gateway location, which is coupled to a high volume ISP peered with other high volume ISPs. Requests are directed to the high volume ISP through a POP on the backbone of the high volume ISP. Responses from the high volume ISP are routed to a hybrid network provider. Responses packets are translated into permanent virtual circuits (PVC) by a router.
