ATM burst traffic generator
Pong P. Chu · 2002
The Markov modulated process is widely used to model ATM (Asynchronous Transmission Mode) traffic sources because it can emulate the bursty and correlated traffic arrival. We propose a hardware sample generator emulating the bursty behavior of the Markov process and develop circuits for a 2-state Markov modulated process and an N-state homogeneous Markov modulated process. The generator can produce traffic imitating cell arrival of various voice and video sources. Our test circuit can be fitted into a moderate-sized FPGA chip and can generate up to 20M cell arrivals per second.
