What does the term ‘Convergence’ refer to in networking?

The term ‘Convergence’ in networking refers specifically to the point at which all routers in a network have consistent routing information. This means that after a topology change, such as a router failing or a new link being added, the routers update their routing tables so that they all reflect the same view of the network.

This is a critical aspect of dynamic routing protocols, as convergence time can significantly affect the performance and reliability of a network. During convergence, routers may exchange routing information between each other to update their tables, ensuring that all devices are aware of the latest network topology and that traffic can be effectively routed.

Understanding convergence is essential because a faster convergence leads to fewer routing loops and more efficient traffic management, maintaining network stability and performance during changes in the network structure.
