A method and apparatus is provided for use in providing real-time, packet-switched service to an end-user over a cable data network. The method begins by transmitting over the cable data network a scheduled grant to an end-user gateway in accordance with an unsolicited grant service protocol. The grant authorizes the end-user gateway to transmit a data packet to a cable modem termination system (CMTS) located in the cable data network. Next, an adjustment is made to the time at which subsequent grants are transmitted. The adjustment, which is based on a response of the end-user gateway, is performed to reduce delay between a time when a subsequent data packet is generated and receipt of the subsequent grant.
