| T. Blackwell, K. Chang, H.T. Kung, D. Lin. Proceedings of the First Annual Conference on Telecommunications in Massachussetts In credit-based flow control for ATM networks, switch buffer space is first allocated to each virtual circuit (VC) and then credit control is applied to the VC to prevent possible buffer overflow. Adaptive buffer allocation improves sharing by allowing dynamic allocation of buffer space to multiple VCs sharing the same buffer pool. This paper gives an overview of credit flow control and presents performance results from simulations. |
