Abstract

In this paper, we analyze the effects of the distinction between long and short data grants in the Data Over Cable Service Interface specifications (DOCSIS) protocol. According to DOCSIS specifications, the grants for a bandwidth request of a cable modem can be for either short or long data packets. The threshold value classifying a short and long data packet is a system operation parameter and is determined by a cable modem termination system (CMTS). We have tried to find the effect of the distinction at the point of efficiency and robustness. For this, we have checked the bit error rate and transmission efficiency for burst profiles defined in a commercial CMTS.
