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 ...

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, Stacy W Nichols: Parallel service-rate controllers in ATM switches. Nortel Networks Corporation, Yoshiharu Toyooka, Gowling Strathy & Henderson, July 11, 2000: US06088331 (5 worldwide citation)

Techniques of service-rate controls in ATM switches are described, and apparatus for their implementation are devised. The techniques fall in two categories: frequency domain controls, and time-domain controls. The regulators control the service rate on a per-class basis or on a per-connection basis ...

Mihai Focsaneanu, Richard P Skillen, Frederick C Livermore: Access to telecommunications networks in multi-service environment. Northern Telecom, Yoshiharu Toyooka, March 11, 1997: US05610910 (564 worldwide citation)

In current voice telephony, CATV, and wireless networks, traffic is channelized for both access and transport. This channelization is wasteful of resources where multiple services have varying demands for bandwidth and holding times, or a service generates traffic that is bursty in nature. The inven ...

Warwick S Ford, Michael J Wiener: Computer network cryptographic key distribution system. Northern Telecom, Yoshiharu Toyooka, January 2, 1996: US05481613 (116 worldwide citation)

Novel cryptographic key distribution techniques to be used in large computer networks are disclosed. The techniques require trusted key release agent systems in each security domain. The encryptor of a data message nominates the set of authorized decryptors, using a set of access control attributes ...
