Distributed Management Of Leo Satellite Networks With Management Agility And Network Efficiency
US Patent:
8644323, Feb 4, 2014
Filed:
Feb 7, 2012
Appl. No.:
13/368131
Inventors:

Assignee:
Telcordia Technologies, Inc. - Piscataway NJ
International Classification:
H04L 12/28, H04B 7/185, H04W 4/00, H04N 7/20
US Classification:
370400, 455 121, 455427, 725 63
Abstract:
In a distributed management scheme for LEO satellite networks interactions between a satellite and the designated fixed center occur according to a time schedule and only when the designated center is in the coverage area of the payload. For exception/alarm reporting and real-time configuration updates the interaction varies with time. Interactions of this type occur between a satellite and the management center that is “nearest” to the payload or satellite at the time instant at which the network event occurs or configuration upload is needed. The nearest management center for a payload is the center that can be reached from the payload with fewest number of crosslink hops. A central network operation center determines, prior to payload launch, the association between satellites and management centers for routine information exchange, and the nearest management center for the payload for different snapshots of time.
Context Aware Adaptive Switching In Reconfigurable Low Earth Orbit Satellite Networks
US Patent:
2012013, May 31, 2012
Filed:
May 31, 2011

Assignee:
TELCORDIA TECHNOLOGIES, INC. - Piscataway NJ
International Classification:
H04W 28/02
US Classification:
370225
Abstract:
A payload switching architecture for LEO satellite networks minimizes processing and storage requirements of payloads for deployment as small primary or secondary payloads, payloads perform only forwarding functions. Forwarding rules are provisioned in the payloads enabling them to reroute in case of failures or congestion without intervention from a ground station. Configuration rules are provisioned in the payloads enabling them to dynamically establish and remove interplane crosslinks without intervention from a ground station. The central network operations center on the ground computes forwarding rules and configuration rules for payloads and uploads the rules to the payloads.
Method And System For Determination Of Routes In Leo Satellite Networks With Bandwidth And Priority Awareness And Adaptive Rerouting
US Patent:
2012026, Oct 18, 2012
Filed:
Oct 4, 2011
Appl. No.:
13/252711

Assignee:
TELCORDIA TECHNOLOGIES, INC. - Piscataway NJ
International Classification:
H04L 12/26
US Classification:
370238
Abstract:
In Low Earth Orbit (LEO) satellite networks data routes for point to point and point to multipoint communication sessions in LEO satellite networks are determined by considering session bandwidth, priority, and the constantly changing terminal-satellite and satellite-satellite connectivity. Multiple routes are computed for a session to facilitate automatic adaptive rerouting by satellite payloads when they encounter network failures or congestion conditions.
