Based on Bump-In-the-API (BIA) architecture, this letter proposes a Socket-layer Translator called NCTU SLT that translates IPv4 applications to IPv4/IPv6-capable applications on dual-stack hosts. Like previously proposed approaches, NCTU SLT can translate NAT-friendly applications (e.g., HTTP and TELNET) without modifying the source codes of the IPv4 applications. Furthermore, NCTU SLT has the advantages over the previous approaches for translating non-NAT friendly applications (i.e., SIP and FTP).
