Path Vector Protocol

The Path Vector Protocol is a method used by large networks, like the internet, to find the best route for data to travel from one computer to another. Each router keeps a list of network paths it knows about, including how to reach other networks and the route's characteristics. When a router receives new information, it updates its list to reflect the current state of the network. This way, routers can avoid loops and select efficient paths, ensuring data reaches its destination reliably and efficiently. The protocol helps manage and scale the complex web of interconnected networks.
