Latest Patents

One of Vogel's latest patents is titled "Communication of packet arrival times to cable modem termination system and uses thereof." This invention allows a cable modem to communicate the timing of the arrival of specific packets, such as TCP ACK packets, to a cable modem termination system. This timing feature is instrumental in increasing downstream throughput by preventing TCP ACKs from backing up at the cable modem. The patent describes methods for sending unsolicited bandwidth grants from the cable modem termination system to the cable modem, ensuring that these grants arrive simultaneously with or shortly after the TCP ACK packets. This method is also applicable to other packet types, including voice packets from VoIP applications.

Another notable patent is "Method for improved cable modem ranging in a data-over-cable system." This invention outlines methods for enhancing cable modem ranging by utilizing a characteristic value that describes network equipment configuration. By estimating loss in the upstream path from downstream signal measurements, a cable modem can determine its initial transmit level during ranging. This approach helps ensure that range request messages reach the cable modem termination system with adequate strength, thereby improving the overall ranging process and reducing collisions when multiple cable modems attempt to range simultaneously.
