Abstract
In cable modem termination systems (CMTS) and other information transmission systems, a method for changing the interleave depth associated with each data stream is provided. This may be done dynamically, and for any subset of downstream devices such as modems. The interleave depth may be set on an individual device level. Embodiments may decrease data receiving latency on devices that do not suffer from error rates, such as caused by burst noise, while maintaining throughput on devices with high error rates.
Claims1
A method, comprising:
- receiving, by at least one computing device, a first map indicative of a plurality of first timeslots based on a plurality of interleave depths associated with a plurality of data streams destined for a plurality of devices, wherein the plurality of interleave depths includes a first interleave depth and a second interleave depth different from the first interleave depth;
- modifying one or more of the plurality of first timeslots to form a plurality of second time slots;
- constructing a second map indicative of the plurality of second timeslots;
- and
- transmitting the second map to at least one of the plurality of devices.
