Bandwidth Allocation Mechanism (BAM) is based on the stream peak rate, and it is used inside premium service Architecture in order to support real-time stored stream transmission.It, therefore, helps in checking the need for additional bandwidth allocation in multi-media transmission in any communication channel.Notes:The token bucket is an algorithm used in packet-switched computer networks and telecommunications networks.It can be used to check that data transmissions in the form of packets, conform to defined limits on bandwidth and burstiness (a measure of the unevenness or variations in the traffic flow).The token bucket depth represents the single burst size configured for the policer.
