Maged E Beshai, Richard Vickers: State information and routing table updates in large scale data networks. Nortel Networks, September 13, 2005: US06944131 (67 worldwide citation)

In a communication network comprising nodes and links between the nodes, a controller node disseminates link state information. A nodal routing table exists at each node comprising routes between pairs of nodes. The nodal routing table is either populated by the given node based on network informati ...

Maged E Beshai, James Yan: Call routing in an ATM switching network. Northern Telecom, Yoshiharu Toyooka, May 13, 1997: US05629930 (67 worldwide citation)

A routing scheme for an ATM switching network includes a plurality of switching nodes, each of which includes individual storage for storing routing messages for each outgoing link. A call at a source node is routed through one possible routing path which requires only one or two links to complete a ...

David A Brown, Stacy W Nichols, Maged E Beshai: Multi-core ATM switch with cells in the core from an inlet for an outlet being aligned. Northern Telecom, April 20, 1999: US05896380 (58 worldwide citation)

A multi-stage ATM switch has a plurality of inlet stage fabrics, core stage fabrics and outlet stage fabrics. ATM cells routed by the switch have destination fields including (i) an identification of the outlet stage fabric and (ii) an identification of the outlet port. Cells incoming to a given inl ...

Maged E Beshai: High-capacity WDM-TDM packet switch. Nortel Networks, Steubing McGuiness & Manaras, April 5, 2005: US06876649 (41 worldwide citation)

A self-configuring distributed packet switch which operates in wavelength division multiplexed (WDM) and time division multiplexed (TDM) modes is described. The switch comprises a distributed channel switching core, the core modules being respectively connected by a plurality of channels to a plural ...

Maged E Beshai, Ernst A Munter: Rate-controlled multi-class high-capacity packet switch. Uortel Networks, Steubing McGuinness & Manaras, April 5, 2005: US06876629 (39 worldwide citation)

A packet switch includes ingress modules, egress modules, and a switch core. Packets of variable sizes may be divided into segments of predetermined sizes to facilitate switching within the switch core. The segmentation process may require null-padding which increases the flow rate within the switch ...

Francois J Blouin, Dinesh Mohan, Maged E Beshai: Technique for autonomous network provisioning. Nortel Networks, Hunton & Williams, July 22, 2008: US07403988 (33 worldwide citation)

A technique for autonomous network provisioning based on establishing a relation between network performance indices, traffic measurements and resource capacities, which provides automatic provisioning recommendations for identified critical links is disclosed. The technique may be implemented in a ...

Maged E Beshai, Ernst A Munter: High capacity ATM switch. Northern Telecom, Yoshiharu Toyooka, April 28, 1998: US05745486 (29 worldwide citation)

An ATM switch architecture expandable to multi-terabits/s uses data transfer in a heterogeneous burst of a constant length. It employs rotators connecting stages in a three-stage switch configuration. In one embodiment, the cells are sorted at ingress and a matching process is performed between the ...

Maged E Beshai, Richard Vickers: Burst switching in a high capacity network. Nortel Networks, June 14, 2005: US06907002 (26 worldwide citation)

At a master controller of a space switch in a node in a data network, a request is received from a source node that requests a connection to be established through the space switch. This request is compared to other such requests so that a schedule may be established for access to the space switch. ...

Francois J Blouin, Dinesh Mohan, Maged E Beshai: System and method for network control and provisioning. Nortel Networks, McGuinness & Manaras, July 24, 2007: US07249169 (26 worldwide citation)

A multi-stratum multi-timescale control for self-governing networks provides automatic adaptation to temporal and spatial traffic changes and to network state changes. Microsecond timescale reacting through the routing function, a facet of the lowest stratum, allows a source node to choose the best ...

Maged E Beshai, Stacy W Nichols, Todd D Morris: ATM service scheduler using reverse-binary scattering and time-space mapping. Nortel Networks Corporation, March 7, 2000: US06034960 (26 worldwide citation)

A method for scheduling low delay-jitter cell transmissions for multiple streams of Asynchronous Transfer Mode (ATM) traffic from a node is disclosed. Cells belonging to multiple streams of virtual circuits (VCs) and virtual paths (VPs) are stored in the node's memory. A link controller scans a time ...
