This makes multi-homing with IPv4 and IPv6 increasingly common even with just a single ISP connection. Furthermore, the growing popularity of multi-path transport, especially Multi-Path TCP~(MPTCP) that is the extension of the well-known Transmission Control Protocol~(TCP), leads to the question of whether this identity duality can be utilized for improving application performance in addition to providing resilience. In this paper, we first investigate the AS-level congruency of IPv4 and IPv6 paths in the Internet. We find that more than 60\% of the current IPv4 and IPv6 AS-paths are non-congruent at the AS-level, which motivates us to explore how MPTCP can utilize the IPv4/IPv6 identity duality to improve data transfer performance. Our results show that MPTCP, even with a single dual-stack Internet connection, can significantly improve the end-to-end performance when the underlying paths are non-congruent. The extent of the improvement can reach up to the aggregate of the IPv4 and IPv6 bandwidth.}", url = "https://www.simula.no/file/gis2015pdf-0/download", url.size = "334367", url.md5 = "62683a568c45c655151216105a168310", url.mime = "application/pdf", url.pagesize = "595.276 x 841.89 pts (A4)", url.checked = "2015-03-13 14:29:03 CET" }
