Network routing is a critical aspect of computer networking that involves determining the optimal path for data packets to travel from their source to their destination. This is typically done by network routers, which use various algorithms and protocols to make routing decisions based on factors such as network congestion, reliability, and shortest path. Network routing plays a key role in ensuring efficient and reliable communication across complex computer networks, such as the internet. Researchers in this area work on developing new routing algorithms, protocols, and technologies to improve network performance, security, and scalability.
