Each router creates a distance vector table that contains information about the routers in the network, specifically, the cost associated to reach every router from this particular router (this is the cost of the path that the packet may take to travel). This path cost is shared by each router with its neighbors. Each router is connected to some other routers and the path through which we can reach the other router has certain costs involved with it. ![]() ![]() So, think of all these routers in the networks as nodes in a graph. Usually, in these networks, the routers handle the work of directing the traffic. So, when a request is made from a network, the requested information comes in packets that travel across these networks. As we know, the internet is a network of networks. The distance vector routing protocol is one of the main protocols used for routing packets across networks. These packets travel across networks as per a defined protocol. ![]() Our devices then assemble these packets for us to understand the information. ![]() With the help of these packets, we receive the information that we request from the internet. When we use the internet, the information across networks travels across the planet in small distributed pieces called packets. In this article, we have covered the idea of Distance Vector in Computer Network in depth along with Routing and Distance Vector Routing protocol.
