Term	Kind	Topic	What it is
Rate Limit Design Token Bucket, Sliding Window	practice	Rate Limiting	The algorithm, scope and response behaviour that determine whether throttling protects the service and treats callers fairly.
Rate Limiting in Practice Throttling, Quota Enforcement	pattern	Rate Limiting	Bounding how much work one caller can demand, the algorithm choice that shows through to users, and why distributed enforcement is approximate.
Retry-After	protocol	Rate Limiting	A response header telling a client how long to wait before retrying, turning a rejection into actionable guidance.
Token Bucket	pattern	Rate Limiting	A rate-limiting algorithm holding a replenishing allowance of tokens, permitting controlled bursts while bounding the sustained rate.
