DDoS Mitigation & Scrubbing Centers: Inline GRE Tunnels & BGP Flowspec
Technical Review: MassiveColo Critical Infrastructure Engineering Group
Defending against multi-terabit volumetric attacks: BGP Flowspec RFC 8955 filters, clean-pipe GRE tunnel diversion, and hardware mitigation appliances.
Modern volumetric DDoS attacks regularly exceed 2 to 3 Terabits per second (Tbps), easily overwhelming standard data center upstream bandwidth without automated edge scrubbing.
1. Distributed DDoS Mitigation Flow Architecture
| Attack Vector | Detection Mechanism | Mitigation Technique | Latency Impact |
|---|---|---|---|
| Volumetric (NTP/DNS Amp, UDP Flood) | NetFlow / IPFIX flow sampling | BGP Anycast redirect to Multi-Tbps Scrubbing Center | + 2ms to 8ms during attack |
| Protocol (SYN Flood, ACK Reflection) | Stateful TCP tracking engine | SYN Proxy Challenge / Token Validation | < 0.5ms |
| Application Layer (HTTP GET/POST Flood) | Deep Packet Inspection (DPI) | TLS Fingerprinting & Challenge-Response | < 1ms |
