Implementing High Performance VPN Router using Cavium-s CN2560 Security Processor

Authors: Sang Su Lee, Sang Woo Lee, Yong Sung Jeon, Ki Young Kim


IPsec protocol[1] is a set of security extensions developed by the IETF and it provides privacy and authentication services at the IP layer by using modern cryptography. In this paper, we describe both of H/W and S/W architectures of our router system, SRS-10. The system is designed to support high performance routing and IPsec VPN. Especially, we used Cavium-s CN2560 processor to implement IPsec processing in inline-mode.
