Fast IPSec: A High-Performance IPsec Implementation
Samuel J. Leffler, Errno Consulting
Fast IPsec is an implementation of the IPsec protocols[Kent & Atkinson, 1998a].for FreeBSD that was designed for high performance.In particular the protocols use theOpenBSD Cryptographic Framework, as portedto FreeBSD,[Leffler, 2003].so any cryptographic hardware is automatically usedto accelerate their operation.Fast IPsec, running on a uniprocessor system with a singleBroadcom BCM5822 cryptographic processor,has demonstrated throughput ofmore than 400 megabits/second when acting as an IPsec terminator.This is more than 50% higher than any other freely availableIPsec implementation.
