Volumeric DDoS Attacks Impact CDN Availability. Solarflare’s XtremeScale Ethernet NICs Provide CDNs with Resilience Against DDoS Attacks.
CDNs provide high-availability infrastructure to deliver content (videos, applications, and other media) to users. Critical for this role is high performance delivery of small packets in a manner that is energy and CPU efficient. Also critical is the ability to mitigate distributed denial of service (DDOS) attacks, since CDNs are second only to financial services as an attack magnet. Solarflare XtremeScale adapters provide the tools that CDNs need to deliver packets fast, efficiently, and under all conditions.
CDNs: The Problem With Conventional NICs and DDoS
The Problem: Filtering Incoming Packets With CPU Software
With conventional NICs, the only choice to filter out bad web requests is through software running on the CPU. This approach significantly reduces throughput of good packets, resulting in a CDN “brownout”.
The Solution: Solarflare’s SolarSecure (Hardware Packet Filter)
Solarflare’s SolarSecure (Hardware Packet Filter) inspects packets in NIC hardware (i.e., no CPU workload). The result is that even in the face of particularly virulent DDoS attacks, Solarflare Ethernet adapters continue to deliver packets with high performance.
