What does the acronym OSPF stand for?

Open Shortest Path First
Open Secure Path Filter
Optimal Shortest Path First
Open Source Path Framework

The correct answer is: Open Shortest Path First

The acronym OSPF stands for Open Shortest Path First. This is a widely used routing protocol in Internet Protocol (IP) networks that helps in determining the most efficient path for data to travel across a network. OSPF operates using a link-state routing algorithm and is categorized as an Interior Gateway Protocol (IGP). Its primary function is to facilitate the exchange of routing information among the routers within a single autonomous system, allowing for faster convergence and optimal network routing. Understanding OSPF's significance in network design and operations is crucial, as it provides features like hierarchical routing through area segmentation, which improves scalability and performance in larger networks.
