Latest Patents

One of his latest patents is titled "Dynamic ATM connection management in a hybrid fiber-coax cable network." This invention describes an ATM cable network that includes multiple ATM subscriber interface units or set-top boxes (STBs) located in individual neighborhood homes. The system utilizes a coax distribution plant to provide various communication channels between the STBs and a neighborhood node. A cable headend serves the neighborhood node and its associated STBs through a fiber-optic trunk, offering multiple communication channels or frequencies. The headend features an ATM node switch with switch ports linked to each communication channel. A resource manager at the headend assigns individual STBs to their respective communication channels. The STBs share both upstream and downstream communication channels and switch ports. In an extended autoregistration procedure, the ATM node switch assigns exclusive ranges of VPI/VCI values to the individual STBs tuned to a single switch port. During ATM cell transfer, an ATM cell originating from or destined for a specific STB uses a VPI/VCI value within the range of routing indicators assigned to that STB. This configuration allows the headend to identify the source of all upstream data cells and enables STBs to disregard any cells not intended for them.
