題目(Title) Bechmarking Methodology for Stateful NAT64 Gateways
概要(Abstract) The transition to IPv6, the new version of the widely used Internet Protocol responsible for the operation of the Internet, from IPv4, its legacy version, lasts for decades. During this time, various IPv6 transition technologies are used to enable the cooperation of IPv4 and IPv6, which are incompatible with each other. Stateful NAT64 can be used to enable IPv6-only clients to communicate with IPv4-only servers. The performance of the various stateful NAT64 implementations is an important decision factor for network operators to choose the most appropriate implementation for their networks. RFC 8219 has defined a benchmarking methodology for IPv6 transition technologies. This presentation gives an insight into the RFC 8219 compliant methodology for benchmarking stateful NAT64 gateways described in our IETF BMWG Internet-Draft

講演者紹介(Introduction of Lecturer) Gábor Lencse received MSc and PhD in computer science from the Budapest University of Technology and Economics, Budapest, Hungary in 1994 and 2001, respectively. He works for the Department of Telecommunications, Széchenyi István University, Győr, Hungary since 1997. Now, he is a Professor. He is also a part time Senior Research Fellow at the Department of Networked Systems and Services, Budapest University of Technology and Economics since 2005. His research interests include the performance and security analysis of communication systems, especially IPv6 transition technologies. He is a co-author of IETF RFC 8219 which defines a benchmarking methodology for IPv6 transition technologies. In 2017, he was a Guest Researcher at the Laboratory for Cyber Resilience, Nara Institute of Science and Technology, Japan for 6 months, where his research area was the security analysis of IPv6 transition technologies. Currently, he is a Guest Researcher at the Research Laboratory of Internet Initiative Japan, Tokyo, Japan, where his research area is the benchmarking of stateful NAT64 gateways.
