Elias J Nemer: Reducing acoustic noise in wireless and landline based telephony. Nortel Networks, Mintz Levin CohnFerris Glovsky and Popeo PC, June 6, 2006: US07058572 (43 worldwide citation)

Acoustic noise for wireless or landline telephony is reduced through optimal filtering in which each frequency band of every time frame is filtered as a function of the estimated signal-to-noise ratio and the estimated total noise energy for the frame. Non-speech bands and other special frames are f ...

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, 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, Ernst A Munter: Compact segmentation of variable-size packet streams. Nortel Networks, Steubing McGuinness & Manaras, May 3, 2005: US06888848 (23 worldwide citation)

A method is described for segmenting a data stream comprising variable-size packets, a data stream being defined by its source node, sink node, assigned network route, and other attributes. The segments are of equal size and the method concatenates the packets in successive segments in a manner that ...
