Generation Of Redundant Scheduled Network Paths Using A Branch And Merge Technique

US Patent:

8428056, Apr 23, 2013
Filed:

Nov 1, 2002
Appl. No.:

10/286013
Inventors:

Steven A. Rogers - Alton NH, US
Howard C. Reith - Somersworth NH, US
Dale J. Wisler - Atkinson NH, US
Assignee:

Avaya, Inc. - Basking Ridge NJ
International Classification:

H04L 12/28
G01R 31/08
H04L 12/26
G06F 11/00
US Classification:

370389, 370218, 370232, 370253, 370356, 714 41
Abstract:

A method and apparatus for creating and using multiple redundant paths between endpoints in a scheduled communication network, and for sending copies of data down each path. A path calculation is made for one or more redundant paths between designated branch and merge points in a network using scheduled switch/routers, and duplicate packets are transmitted along each path to the merge point. The first packet received among the configured paths at the merge point is forwarded to a resulting data stream and the later (duplicate) copies from other paths are discarded. Path itineraries are configured to maintain temporal packet sequence in the resulting stream. Path status is monitored and additional paths can be substituted if a path has an outage. Alternatively, multiple divergent paths can be configured, and duplicate packets transmitted along each path, where at least one path delivers data between end points, and a monitoring path also transmits copies of the data to an alternate location. A new routing header may be attached to packets transmitted in the monitoring path, to facilitate conformance with CALEA monitoring requirements.

US Patent:

8520520, Aug 27, 2013
Filed:

Nov 6, 2003
Appl. No.:

10/703186
Inventors:

Sean S. B. Moore - Hollis NH, US
Howard C. Reith - Lee NH, US
Paul Sprague - North Berwick ME, US
Assignee:

Avaya, Inc. - Basking Ridge NJ
International Classification:

H04L 12/28
US Classification:

370235, 370389
Abstract:

A software and hardware system that provides for per flow guaranteed throughput and goodput for packet data flows using network transport protocols that have window-based flow control mechanisms or TCP-friendly flow control mechanisms. The system and method for guaranteed throughput of individual flows in turn enables a method for provisioning link bandwidth among multiple flows and provisioning network throughput and goodput at the granularity of individual flows. The invention also eliminates Layer 3 packet drops for a data flow using window-based flow control or TCP-friendly flow control, which in turn obviates congestion collapse and quality collapse scenarios.

US Patent:

20030219012, Nov 27, 2003
Filed:

Mar 7, 2003
Appl. No.:

10/383698
Inventors:

Dale Wisler - Atkinson NH, US
Howard Reith - Somersworth NH, US
David Milley - Merrimac MA, US
International Classification:

H04L012/66
US Classification:

370/356000, 370/442000
Abstract:

A system and method to emulate any TDM circuit on a Real-Time Scheduled Packet Network. The TDM circuit can be any serial or parallel bit stream, of any bit rate, and can either be synchronized to the Real-Time Scheduled Packet Network, or can be asynchronous to the network. The present system and method determines the requisite descriptors of a scheduled IP itinerary for any emulated TDM circuit.
