Here at Lightyear, we find it helpful to break LAN down into three zones – Zone A (the network edge, where the LAN hands off to the WAN), Zone B (the core network), and Zone C (the endpoints, or individual devices and users accessing the LAN). The network edge equipment is commonly composed of. That's where Wide Area Network (WAN) design considerations come into play. A well-planned WAN design allows data to flow and helps with effective team collaboration. Our guide covers these 8 steps to prepare your WAN design: We'll also cover why Meter can solve your WAN problems by doing the design. Just as the plumbing in a large stadium or a high-rise building is designed for scale, purpose, redundancy, protection from tampering or denial of operation, and the capacity to handle peak loads, the network requires similar consideration. This product area includes hubs, switches, routers, bridges, gateways, multiplexers, transceivers and firewalls. Stay tuned for more about this exciting new trend in NGFWs.
