WebAlpha is a ratio of propagation delay over the frame transmission time. In one persistent CSMA, its maximum Throughput throughput is better than that of Aloha schemes for small alpha. But it is worse as alpha is greater than one. The other two CSMA options are non-persistent CSMA and p-persistent CSMA. Non-persistent CSMA is the least greedy.
