Response Time Analysis of Distributed Web Systems Using QPNs

Figure 8

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