Yes, there’s something to say about how applications are written, but on the public internet side, we’ve seen a decrease in latency, cost, and a massive increase in available bandwidth. We still need to connect our infrastructure to the public internet, so the enterprise WAN is still about routers, circuit IDs, and perimeter firewalls.

MPLS (Multiprotocol Label Switching) is a network routing technique that is based on predetermined paths, instead of routers determining the next hop in real-time. This enables quicker and more efficient routing, as the router only needs to view a packet label, instead of looking up the address destination in complex routing tables.
