A network topology describes the arrangement of systems on a computer network. It defines how the computers, or nodes, within the network are arranged and connected to each other. Some common network topologies include star, ring, line, bus, and tree configurations. A network topology is a pattern in which nodes (i.e., computers, printers, routers or other devices) are connected to a local area network (LAN) ot other network via links (e.g., twisted pair copper wire cable or optical fiber cable). When a network is to cover a large geographical area, which is a common case nowadays, the topology mapping is likely to be more difficult. Motivated by this reason, a specific application was designed to be able to map any given network topology remotely. Through the testing phase pn various network topologies, it shows a success percentage of 88% with an average execution time of 32.05 seconds. Besides, the application can provide the user with specific information about the existing devices, such as hostname, IP address and MAC address. For further improvement, the future application is expected to be able to deal with extracting more data and compatible on multiplatform. Keywords: Application, Network Topology
