This paper focuses on the ABR(Available bit rate) congestion control algorithm in the satellite ATM network based on onboard processing, which is implemented by using the traffic prediction.

ABR (available Bit Rate) service will systematically and dynamically allocate available bandwidth to users by controlling the flow of traffic with feedback.

This paper proposes an approach to design a rate based flow control mechanism in order to regulate the Available Bit Rate (ABR) traffic and effectively control congestion of the networks.
