Turbo TCP
Turbo
Turbo TCP is a sophisticated network traffic prioritization and queuing method that dramatically improves
the performance of downstream TCP/FTP/HTTP transfers under heavy upstream bandwidth utilization
conditions.
This feature first assigns a high priority to TCP signaling packets in the upstream direction, then places the
packet in one of several transmit queues based on this priority.
Packets of unspecified priority, like TCP or UDP data, are assigned a low priority and placed in a low priority
queue.
The packets in the high priority queues are then transmitted before packets in the lower priority queues
minimizing any transmit delays.
Minimizing the transmit delay of the TCP messages upstream enables the server to send the TCP data
downstream faster, resulting in a substantial throughput gain.
