Path Vector Protocol Definition: Path Vector Protocol: A routing protocol that makes routing decisions based on the path vector, which includes the network and autonomous system numbers, allowing for more effective route selection and prevention of routing loops.
Path Vector Protocol is a type of routing protocol used in computer networks to determine the best path for routing data packets. It works by considering multiple factors such as the number of hops, network congestion, and network policies to select the optimal path for data transmission. Examples of Path Vector Protocols include Border Gateway Protocol (BGP), which is widely used in the Internet for routing decisions based on paths with the shortest Autonomous System (AS) path.
