Abstract

An apparatus can include a session rate limit calculator and a rate limiter. The session rate limit calculator can be configured to compute a session rate limit for a given session of a plurality of active streaming media sessions based on state information for the given session and state information for a downstream bottleneck link to which the apparatus feeds the plurality of active streaming media sessions. The rate limiter can be configured to control downstream traffic for the given session based on the computed session rate limit and to provide corresponding rate-limited downstream traffic for the given session.
