| 1. A method of identifying a message collision in an upstream channel of a satellite based DOCSIS communications system, comprising:
generating, by a satellite gateway, a media access protocol (MAP) message having a plurality of fields, the generating including
identifying a message collision between satellite modems in an unused explicit congestion notification (ECN) field of the
MAP message,
wherein the ECN field (i) is a reserved field in a standard Data Over Cable Interface Specification 1.1 MAP message and (ii)
includes at least one subfield.
