Abstract: The relationship between the important service parameter credit and message transmission bandwidth allocation for Fibre Channel-Arbitrated Loop (FC-AL) is analyzed for configuring the credit reasonably to avoid buffer overflow in nodes.The optimipation of credit are derived on the traffic load balance of each node.

Key words: fibre channel, arbitrated loop, reliability, bandwidth allocation, credit
