Term	Kind	Topic	What it is
Admission Control	pattern	Load Shedding	Deciding at the edge whether to accept a request at all, based on current capacity, before any work is done on it.
Brownout	pattern	Load Shedding	Deliberately reducing the quality or completeness of every response under load, rather than serving some requests fully and rejecting others.
Priority Queueing	pattern	Load Shedding	Classifying requests by business importance so that overload sheds the least valuable work first rather than an arbitrary slice.
