Response Time Analysis of Distributed Web Systems Using QPNs

Figure 9

Mean response time simulation results for different number of nodes in BE (1, 3, 6, and 9) layer and in FE (1, 3, 6, and 9) and different numbers of clients: (a) 1 node in BE layer and 1, 3, 6, and 9 in FE layer, (b) 3 nodes in BE layer and 1, 3, 6, and 9 in FE layer, (c) 6 nodes in BE layer and 1, 3, 6, and 9 in FE layer, and (d) 9 nodes in BE layer and 1, 3, 6, and 9 in FE layer.
