DOCSIS upstream burst efficiency maximization and support for jumbo frames

摘要

A method for passing ingress and egress jumbo frames and maximizing the use of frame bursts in a cable modem including, receiving from a client device one or more packets to be transmitted over a communication channel, queuing the one or more packets, determining a maximum size of a burst frame transmitted over the communication channel, adding each of the one or more packets in their entirety to the burst frame until the maximum size of the burst frame is reached, determining whether the burst frame has available space, when space is available, fragmenting a packet of the one or more packets into at least a first and a second fragment packet, wherein the first fragment packet has a size substantially equal to the available space of burst frame, and adding the first fragment packet to the burst frame and transmitting the burst frame during a transmit window.

主权项

1. A method for maximizing the use of frame bursts in a cable modem comprising:
receiving from a client device one or more packets having a first communication protocol, to be transmitted over a communication channel using a second communication protocol; queuing the one or more packets; determining a maximum size of a burst frame that is transmitted over the communication channel; adding each of the one or more packets in their entirety to the burst frame until the maximum size of the burst frame is reached; determining whether the burst frame has available space; fragmenting using the first communication protocol, when there is available space, a packet of the one or more packets into at least a first fragment packet and a second fragment packet, wherein the first fragment packet has a size substantially equal to the available space of the burst frame; adding the first fragment packet to the burst frame when there is available space; and transmitting the burst frame over the communication channel using the second communication protocol during a transmit window.
