William Paul Sherer, David R Brown, Richard Reid, Glenn Connery, Chi Lie Wang: Method and apparatus for time-based download control. 3Com Corporation, Townsend and Towsend and Crew, February 23, 1999: US05875175 (35 worldwide citation)

A network transmitter schedules packets so that packets are transmitted to a host or group of hosts so as not to overload any particular part of the network. In an embodiment, the transmitter uses packet data structures with a schedule indication for packets placed in the queue so that an independen ...

Vipin Kumar Jain, Danny M Nessett, William Paul Sherer: Method and apparatus for providing security in a star network connection using public key cryptography. 3Com Corporation, Wagner Murabito & Hao, October 30, 2001: US06311218 (26 worldwide citation)

An intermediate system authenticates using cryptography. The authentication routine requires a user to supply a secret known only to the user before allowing data to be transmitted. The secret is never transmitted. The invention may be incorporated into an intermediate system, into intermediate syst ...
