Neighbor node discovery using ospf algorithm

the nodes in the network act as router. The router forwards data packets from one node to another. A router is connected to at least two networks, commonly two LANs or WANs. Routers are located at gateways, the places where two or more networks connect. When a data packet comes in one of the lines, the router reads the address information in the packet to determine its ultimate destination. Routers perform the “traffic directing� functions on the internet. A data packet is typically forwarded from one router to another through the networks until it reaches its destination node. The packet sending from one node to another is based on the shortest path. The link cost determines the shortest path between nodes. Packet capturing (or packet sniffing) is the process of collecting all packets of data that pass through a given network interface. Capturing network packets in our applications is a powerful capability which lets us write network monitoring, packet analyzer and security tools.
