“…CAIDA has shown that, from January 2014 to January 2015, the number of IPv6 ASes increased by 23% and the number of links between them increased by 29% [9]. Existing studies have addressed that IPv6-centric next generation networks are widely deployed and applied [10][11][12]. With the development of IPv6, applications such as video conference, IPTV, VoIP, and online games will become more and more prevalent in IPv6 networks, so keeping network availability as well as good performance is crucial.…”

Internet Protocol (IP) is used to identify and locate computers on the Internet. Currently, IPv4 still routes most Internet traffic. However, with the exhausting of IPv4 addresses, the transition to IPv6 is imminent, because, as the successor of IPv4, IPv6 can provide a larger available address space. Existing studies have addressed the notion that IPv6-centric next generation networks are widely deployed and applied. In order to gain a deep understanding of IPv6, this paper revisits several critical IPv6 performance metrics. Our extensive measurement shows that packet delay and loss rate of IPv6 are similar to IPv4 when the AS-level paths are roughly the same. Specifically, when the link utilization exceeds a threshold, for example, 0.83 in our study, variation of packet delay presents a similar pattern with the variation of link utilization. If packet delay of a path is large, packet-loss rate of that path is more likely to fluctuate. In addition, we conduct a first-ever analysis of packet reordering in IPv6 world. Few IPv6 probe packets are out-of-order and the reordering rate is 2.3 * 10 −6 , which is much lower than that of 0.79% in IPv4 world. Our analysis consolidates an experimental basis for operators and researchers of IPv6 networks.

“…EIGRPv6 is simple to be configured while the configuration in OSPFv3 is difficult because it works in areas and there are numerous types of areas, each of them can be stubby, transit or not so stubby. Differences in these areas and their purposes may increase the level of understanding and difficulty of configuration [4].…”

“…Other closely related works are presented in [4,13,14,15,24,26] in which authors compared and analyzed two routing protocols (OSPFv3 & EIGRPv6) based on their performance in a small network. In [4], the researchers focused on configuration analysis and compared IPv6 configuration commands with IPv4 configuration commands and analyzed that IPv6 configuration commands are more complex than IPv4 configuration commands because of IPv6 addresses complexity.…”

“…It will gradually replace IPv4 throughout the world. IPv4 is comparatively easy to configure, however, IPv6 is more complicated due to its nature of complex addresses [4]. Furthermore, IPv6 has more advantages than IPv4 in terms of header format simplification, efficient routing, built-in security, QoS and route optimized mobility [5,6].…”
