Distance Vector Routing (DVR) is a fundamental algorithm in computer networking used for finding the shortest path between nodes in a network. This blog post explores a C++ implementation of the DVR algorithm, demonstrating how it calculates and updates routing tables dynamically.
What is Distance Vector Routing?
DVR is a decentralized routing protocol where each router maintains a table containing the shortest distance to every other router in the network. Periodically, routers exchange this information with their neighbors, updating their tables accordingly.
C++ Implementation
The following C++ code demonstrates the DVR algorithm by:
Initializing a network graph with user-defined distances.
Sharing distance vectors between nodes.
Iteratively updating routing tables until convergence.

The Distance Vector Routing (DVR) Algorithm is a fundamental routing algorithm used in computer networks to determine the shortest path between nodes. It is based on the Bellman-Ford algorithm and operates by sharing routing tables among directly connected nodes to update their knowledge about the shortest paths.
In this blog post, we will discuss the implementation of the DVR algorithm in C++, go through the code step by step, and explain its output.
