Latest Patents
One of his latest patents is titled "System providing dynamic quality of service signaling messages in a cable telephony network." This innovative system involves encrypting Quality of Service signals and transmitting them indirectly via a Broadband Telephony Interface, rather than directly from an Internet Protocol Digital Terminal to a Cable Modem Termination System. The Broadband Telephony Interface, which does not possess the encryption and decryption keys, includes the encrypted Quality of Service signaling message in a signaling message sent to the Cable Modem Termination System when requesting a change in access to network resources. The Cable Modem Termination System then attempts to decrypt the Quality of Service signaling message and controls access to network resources based on the contents of the message if decryption is successful. This system effectively reduces the number of signaling messages and network resources required for call processing while providing enhanced security against denial-of-service attacks.
