What is DDoS Mitigation?
Distributed Denial of Service (DDoS) attacks utilize thousands or millions of distributed devices (botnets) to overload specific servers, networks, or services, preventing legitimate users from accessing them normally.
PacketStream combines Multi-Layered defense and real-time traffic filtering to protect assets and services from such large-scale attacks.
- Automatic threat detection and response
- Layer-specific defense across L3/L4/L7
- Uninterrupted protection backed by N+1 redundancy
How does PacketStream protect infrastructure from DDoS attacks?
PacketStream responds to attacks on its self-built global network.
1. Terabit-Scale Capacity Infrastructure
PacketStream possesses terabit-scale network processing capacity, enabling it to quickly absorb and neutralize large-volume attack traffic at the network level.
2. Edge Filtering
Identifies and removes malicious traffic at the nearest edge (POP). Attacks are blocked before they reach backend resources, which keeps latency low.
3. Advanced L7 Filtering
PacketStream provides L7 protection based on application-specific communication characteristics.
It applies per-protocol filtering and authentication mechanisms for protocols such as HTTP, DNS, and SMTP,
going beyond simple pattern blocking to protect legitimate users and block attacks.
4. Adaptive Filtering
PacketStream’s Adaptive Filtering system utilizes machine learning (ML)-based traffic analysis technology to distinguish between normal and abnormal traffic in real-time.
It is designed to respond quickly not only to known attacks but also to Zero-Day attacks.
PacketStream’s Network Topology
The network is built as follows.
1. Global Anycast Network
PacketStream uses Anycast routing technology to receive and distribute attack traffic at the physically closest point.
This improves response speed and prevents single-point bottlenecks caused by attack concentration.
2. N+1 Redundancy Design
Both network and defense systems are designed with N+1 redundancy structure, ensuring traffic flow continues uninterrupted even when hardware failures or network issues occur.
- Redundant routers, switches, and server nodes
- Automatic failover and health check systems
3. Direct Connectivity with Major Carriers and IXs
PacketStream is directly connected through peering with major global/regional ISPs and Internet Exchanges (IX).
This shortens traffic paths to end users and reduces latency.
Note Attack traffic is also distributed and blocked at the initial peering stage, minimizing core network load.
4. Self-Developed DDoS Mitigation Engine
PacketStream operates its own developed DDoS filter engine rather than relying on commercial products.
It allows direct rule tuning and supports application of customer-customized rules.
- Stateless/Stateful packet inspection
- Layer 3/4/7 Multi-stage Inspection
- Real-time rule updates and Zero-Day attack response
