Abstract
Some embodiments of the present invention may include a method to stream packets into a queue for an upstream transmission, send multiple requests for upstream bandwidth to transmit data from the queue and receiving multiple grants to transmit data, and transmit data from the queue to the upstream as grants are received. Another embodiment may provide a network comprising a cable modem termination system (CMTS), and a cable modem wherein the cable modem may transmit data to the CMTS with a streaming protocol that sends multiple requests for upstream bandwidth to transmit data and receives multiple grants to transmit data, and transmits data to the CMTS as grants are received.

7. An apparatus comprising:
-
at least one request grant state machine to launch requests to transmit data to a cable modem termination station and receive grants to transmit data; and
a packet streaming queue state machine to send packet streaming queue requests to the request grant state machine, wherein the packet streaming queue requests are managed separately from the requests to allow data in the packet streaming queue to be parsed in arbitrary data sizes. - View Dependent Claims (8, 9)
