Design of Giga performance VPN router

IPsec protocol (Security Architecture for the Internet Protocol, 1998) 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
