What are the software components of WAN?

The software components of a Wide Area Network (WAN) typically include network management software, which monitors and controls WAN performance; routing protocols, such as BGP or OSPF, that determine the best paths for data transmission; and traffic management tools that optimize bandwidth usage and ensure Quality of Service (QoS). Additionally, security software, including firewalls and VPNs, protects the data being transmitted across the WAN. Lastly, network monitoring tools provide insights into network health and performance metrics.
