The WAN diagram shows a Ring Main topology, where multiple devices are connected in a circular loop, each connected to two adjacent devices. The devices in the diagram include office PCs, switches, and routers, which are connected to each other to provide network connectivity. Each office PC is connected to a switch, which in turn is connected to two other switches forming a ring. The switches are connected to routers, which provide connectivity to other networks or the internet. The Ring Main topology provides redundancy in the network, as traffic can be rerouted in case of a link failure. This design ensures the high availability and reliability of the network, making it suitable for mission-critical applications. EdrawMax is the best diagramming tool to create similar diagrams.
