Abstract:

With the rapid development of network techonology and infrastructure, the network security device VPN plays a more and more important role in network communications. However, the traditional techonology using software encryption can not match the high-speed network any longer. Thus a new parallel arch itecture which combines soft-encryption and encrypt-cards is proposed. In this paper we also discuss the scheduling algorithm of the VPN packets among t he encryption units. The performance of our system is presented and analysed finally.

Key words: packet scheduling, parallel processing, multi-card parallelism, FreeS/WAN
