DDoS mitigation architecture: from attack detection to clean traffic delivery

A strong DDoS mitigation architecture combines upstream capacity, routing control, fast packet filtering, service-aware rules and clean traffic delivery via BGP, tunnel or cross-connect.

Capacity before the customer edge

A strong DDoS mitigation architecture combines upstream capacity, routing control, fast packet filtering, service-aware rules and clean traffic delivery via BGP, tunnel or cross-connect.

Fast filtering path

Clean handoff design

A strong DDoS mitigation architecture combines upstream capacity, routing control, fast packet filtering, service-aware rules and clean traffic delivery via BGP, tunnel or cross-connect.

DDoS mitigation architecture is not a single appliance. It is the way traffic is detected, routed, filtered, delivered and monitored under stress. A strong design decides where attack traffic is absorbed, where clean traffic exits and how the customer keeps control of routing and production services.

This architecture matters for protected IP transit, dedicated protected servers, VPS platforms and gaming proxies because each model has different bottlenecks. The same filter rule can be excellent upstream and dangerous on a customer firewall if placed too late in the path.

Protection model

Where Peeryx fits

A strong DDoS mitigation architecture combines upstream capacity, routing control, fast packet filtering, service-aware rules and clean traffic delivery via BGP, tunnel or cross-connect.

Architecture decides where the attack is handled

The core question is simple: where does the attack hit first? If it reaches the customer link, local equipment and shared services absorb the blast. If it is reduced upstream, the customer receives a more stable handoff.

Many outages happen because the protection exists, but in the wrong place. A WAF, firewall or server rule cannot help when the line is already full or packet queues are already dropping.

Why design matters before buying capacity

Buying more bandwidth is useful only if traffic can be filtered and returned cleanly. Otherwise extra capacity can become a bigger pipe carrying the same problem to the same fragile point.

Architecture also affects latency, routing control, troubleshooting and scaling. Gaming, BGP transit and enterprise applications do not need exactly the same delivery model.

The practical objective is to protect revenue, support teams and brand trust, not just to make a graph look clean. A mitigation article must therefore connect technical symptoms to business continuity: what stays online, what is degraded and how quickly the client can recover normal routing.

Reference building blocks

The common blocks are detection, upstream capacity, fast stateless drops, precise protocol rules, routing decisions, clean traffic delivery and customer-side validation.

Delivery can be native protected IP transit, GRE/IPIP/VXLAN, cross-connect or reverse proxy. The right answer depends on whether the customer owns prefixes, runs one server, manages VPS fleets or exposes a game protocol.

Before choosing a model, define the protected asset precisely: a full ASN, a single prefix, one VPS, one dedicated server or one game endpoint. The best solution changes when the bottleneck is upstream bandwidth, packet rate, firewall state or protocol behavior.

How Peeryx structures the path

Peeryx places the first reduction layer before the customer edge, then delivers cleaner traffic in a way the customer can operate. The architecture is designed around practical handoff, not only marketing capacity.

For operators, this means BGP and tunnel options. For servers or gaming, it can mean protected hosting or proxy delivery where service behavior matters.

This is also why Peeryx separates delivery models instead of forcing every customer into the same product. Transit customers need routing freedom, while gaming and server customers often need a more operationally simple path.

Protected IP transit Use BGP, tunnel or cross-connect delivery when the protected perimeter must sit before your server.

Concrete example

A customer announces a prefix and wants to keep its own routers. Protected transit lets the customer preserve routing control while attack traffic is filtered before delivery.

Another customer runs a single game server. A full BGP model may be unnecessary; a reverse proxy or protected server can be faster to deploy and easier to operate.

Common mistakes

The first mistake is drawing a clean diagram but ignoring return traffic and asymmetric paths. Clean traffic must be delivered and monitored end to end.

The second is mixing every service behind one generic policy. Web, UDP gaming, DNS-like traffic and TCP APIs have different risks and thresholds.

Why choose Peeryx

The right choice is not only advertised capacity: it is the filtering point, precision, clean handoff and the ability to keep customers online during the attack.

FAQ

Is this only for very large attacks?

No. Medium-size attacks can be critical when PPS, state or protocol behavior hits the wrong bottleneck.

Can this protect gaming services?

Yes, when filtering keeps legitimate real-time traffic instead of blocking the whole protocol.

Do I need BGP?

BGP is useful for prefixes and transit, but tunnel, protected server or proxy delivery may fit other cases.

What should be checked first?

Capacity, PPS, routing path, service protocol and how clean traffic returns to production.

Conclusion

A strong DDoS mitigation architecture combines upstream capacity, routing control, fast packet filtering, service-aware rules and clean traffic delivery via BGP, tunnel or cross-connect.

The right choice is not only advertised capacity: it is the filtering point, precision, clean handoff and the ability to keep customers online during the attack.
