In the context of *Computer Networks and Data Mining*, a network topology refers to the arrangement of different network elements such as nodes and links. A dumbbell topology is one such configuration where two sets of nodes (e.g., clients and servers) are connected through intermediate nodes and a central link, resembling the shape of a dumbbell. In this case, the network consists of two client nodes on the left side and two server nodes on the right side. The clients are connected through a central node called `n1`, and the servers are connected through another central node called `n2`. Finally, `n1` and `n2` are directly connected using a point-to-point link. This type of setup helps in simulating real-world client-server communication scenarios, making it valuable for performance analysis, load testing, and data mining of traffic patterns. ### Topology Description Let the network nodes be represented as follows: * Client nodes: `C1`, `C2` * Intermediate node on client side: `n1` * Intermediate node on server side: `n2` * Server nodes: `S1`, `S2` The network will have point-to-point links only. The connections are as follows: * `C1` → `n1` * `C2` → `n1` * `n1` → `n2` * `n2` → `S1` * `n2` → `S2` This forms a dumbbell shape, where the left "weight" consists of two clients connected to `n1`, and the right "weight" consists of two servers connected to `n2`, with the "handle" being the link between `n1` and `n2`. ### Assumptions 1. Point-to-point links are full-duplex and have symmetric bandwidth (e.g., 100 Mbps). 2. Each node has a unique IP address. _____ ______ __________ ___ _________ ____ _______ ___ ____ ___.
