Description: three-tier architecture in e-banking. The First New Brunswick Savings (FNBS) bank has introduced e-banking to its customers. The e-banking infrastructure consists of a cluster of two server nodes linked to each other via a TP monitor, which dynamically balances the workload of each server in the cluster. The processing time at the TP monitor is 0.05 seconds. The e-banking program offers a number of services to its customers, as follows: account identification (AI), view account summary (VS), view last 15 withdrawals (VW), view last 15 deposits (VD), and view interim account report (VR). The elapsed times of services are server-node dependent. These are given in following table along with request priorities
