Abstract
Methods, systems, and products are disclosed for enforcing a rate limit for data traffic. One method identifies a unidirectional stream of data packets flowing though a server to a downstream end user. The unidirectional stream is classified according to a rate class, with each rate class having an associated rate limit. Each rate limit specifies a maximum bit rate at which the unidirectional stream may flow. When the actual bit rate of the unidirectional stream exceeds the maximum bit rate permitted for the associated rate class, packets of data are discarded to reduce the bit rate.
