SAVI Requirements and Solutions for ISP IPv6 Access Network
Fan Shi, Guangwu Hu, Hui Deng, Liang Zhu · 2017
Internet is always confronted with many security threats based on IP address spoofing which can enable impersonation and malicious traffic redirection. Unfortunately, the Internet architecture fails to provide the defense mechanism. Source Address Validation Improvement (SAVI) was developed to prevent IP source address spoofing. Especially, the mechanism is essential for ISPs. However, due to the diversity of address assignment methods, SAVI solution is also different accordingly. This document describes five scenarios of ISPs'IPv6 access network, and moreover, states its SAVI requirements and tentative solutions accordingly.
