Leaky bucket description. Bucket contents increased by T for each complient cell, decreased by one per unit time. Sustainable cell rate algorithm. Traffic contract specified by MBS, which is used to derive tau-s, which is used to monitor sustainable cell rate. 5 cases to consider for discard or changing CLP from 0 to 1.
Network provides feedback so low cell loss can be guaranteed.
Source can transmit between 0 and ACR cells per second.
