Network Topology Detection System

Detecting network topology is essential to cope with any existing or future network changes such as the loss of network devices (routers, switches, or hubs), interfaces going down, or cable issues, any if which might change packets' paths, interfere with the network structure, interface status, or neighbour status, or disconnect and reconnect devices. This paper develops a low-cost network detection system that is responsible for discovering network topology by identifying each network device's neighbours to allowed the network administrators to know where each device and its neighbours are located, maintaining these devices' information in a local database to be used for visualisation purposes to demonstrate relevant changes inside the devices such as IP address, interfaces, and neighbours by using a configured hardware device. This system can be implemented in any large to medium size of network, measured depending on the number of users that join such a network. In addition, it can be used to remotely fix any minor issues that are detected which may later affect the entire network. The experimental results substantiate the fact that the system resolves the high cost of hardware experienced by previous work in this field.
