Operational Mechanics

How packets traverse the Split-Path architecture without introducing latency penalties or MTU fragmentation.

1

Ingress & Scrubbing

Traffic hits NETNOUNCE edge via Anycast BGP. Volumetric DDoS attacks are filtered instantly at the backbone layer using flowspec rules.

2

Encapsulated Handoff

Clean traffic is encapsulated (GRE or VXLAN) and delivered to your designated endpoint router over the public internet, bypassing congestion.

3

Asymmetric Return

Your server replies to the request. Instead of tunneling back, it sends the response directly out your ISP uplink, preserving bandwidth and reducing latency.
