Policing mechanism for resource limited wireless MAC processors
First Claim
Patent Images
1. A method of policing a resource limited wireless processor, the method comprising the steps of:
- providing a two phase policing mechanism;
operating one phase of the policing mechanism to prevent predetermined firmware from being flooded by ill-behaved incoming traffic streams; and
operating the other phase of the policing mechanism to isolate good channel stations from bad channel stations on a wireless medium.

Abstract
A policing mechanism 100 for a resource limited wireless MAC processor. The policing function is enforced at both the host software and embedded firmware. The responsibility of the policer on the host prevents ill behaved flows from flooding the firmware and thus blocking other flows. The policer on the firmware prevents users with bad channels from occupying the channel with low rate transmissions/retransmissions and thus blocking others from transmission.
