Reducing delays for frame relay customers over FR-ATM networks

The ever-increasing implementation of frame relay (FR) over asynchronous transfer mode (ATM) backbone is leading to a considerable latency in customer services running over the network. This paper describes the process of build-up delay in a FR ATM interworking. In addition, this paper proposes a new approach to reduce the latency by increasing the PIR/SIR ratio. Furthermore, a case study is introduced in order to validate the proposed method. Finally, the burstiness, virtual bandwidth and buffer overflow affecting the network performance are discussed.
