AI agents change network traffic patterns completely. Instead of humans opening browsers and apps, autonomous systems start talking directly to APIs, databases, sensors, and other agents. IPv6 removes the address limitations and NAT complexity that break large-scale AI communication.
Large VLAN domains depend on spanning tree. Every topology change triggers recalculation and temporary forwarding loss. EVPN-VXLAN replaces large Layer 2 domains with routed underlays and distributed MAC learning. Regional ISPs use this to connect data centers, IX edge infrastructure, and broadband aggregation networks without stretching spanning tree across sites VXLAN encapsulates Ethernet frames inside … Read more
