Shared buffers ATM (Asynchronous Transfer Mode) switch architecture is based on the input-output buffered non-blocking switch model. The effectiveness of buffer sharing is based on decrease of output port overloading and cell loss probability due to bursty traffic conditions. We investigate and compare cell loss probability of the applied load for three architectures under uniform random and bursty traffic. The results of simulation of the process shows that shared buffer architecture is more effective under bursty traffic conditions.
