Loosing ATM cells in an interworking unit between a high speed local area network such as a Gbit/s CRMA LAN and an ATM based wide area network can be a serious problem due to the retransmissions caused by the higher layer protocol. This paper proposes a Flow Control Protocol, which, exploiting the characteristics of the CRMA scheme, regulates the emission of cells towards the CRMA/ATM interworking unit so that its buffer resources are not saturated. The emission of the ATM stations is controlled via a backpressure mechanism. The capacity of the gateway buffer is virtually increased by utilizing the network latency as well as the station buffers. Main protocol performance are analyzed by simulation.

Abstract
Loosing ATM cells in an interworking unit between a high speed local area network such as a Gbit/s CRMA LAN and an ATM based wide area network can be a serious problem due to the retransmissions caused by the higher layer protocol. This paper proposes a Flow Control Protocol, which, exploiting the characteristics of the CRMA scheme, regulates the emission of cells towards the CRMA/ATM interworking unit so that its buffer resources are not saturated. The emission of the ATM stations is controlled via a backpressure mechanism. The capacity of the gateway buffer is virtually increased by utilizing the network latency as well as the station buffers. Main protocol performance are analyzed by simulation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
