Re: [RPRWG] protection messages
Anoop,
Type B fairness message is generated by Fairness Control Unit (in
hardware) and sent to client, whereas protection messages are generated
MAC control unit (which is implemented in software) and multicast to
other MACs' control units. Combining them is the worst that can happen
(HW vs SW, microsecond time frame vs millisecond time frame etc.)
Thanks.
