IPv6 Ingress Filtering in a Multihoming Environment

Abstract

SDSA is a very simple mechanism, capable of solving one main problem in IPv6 multihomed environment, namely, the ingress filtering issue. As it requires minor modifications to the network behaviour and does not increase the process complexity, SDSA gives immediate benefits to first adopters. It decreases the packet loss ratio, since it routes packets to the ISP which delegated their source address prefix.
