Abstract:
A link-level flow control method for serving ATM cell streams arriving from a number of packet sources comprising the steps of:determining a requested bandwidth share for each packet source; queuing ATM cells arriving from the packet sources in a shared FIFO buffer; identifying non-violating packet sources and violating packet sources based on the number of transmitted ATM cells during a pre-defined time period, with the non-violating packet sources being the packet sources that during the predefined time period do not require more than their requested bandwidth share, and violating packet sources being the packet sources that during the same period require more than their requested bandwidth share; granting no more than their requested bandwidth share to the non-violating packet sources; and granting a remaining bandwidth not granted to the non-violating packet sources to the violating packet sources.
