World IPv6 Day sees higher IPv6 traffic than ever before

Not surprisingly, World IPv6 Day saw more IPv6 traffic on a number of networks than they had ever seen before. However, the event also showed that a significant number of users can deploy IPv6 without experiencing significant technical problems, FierceTelecom reports.

The report said World IPv6 Day was a clear success because it lacked serious technical problems, but it is difficult to evaluate the event's full impact without a close analysis of actual IPv6 traffic on a variety of networks.

According to Tim Winters of the University of New Hampshire's Interoperability Laboratory, the Internet Society saw approximately double the normal amount of IPv6 traffic. FierceTelecom said IPv6 traffic typically claims approximately 0.3 to 0.5 percent of all traffic. More interestingly, World IPv6 Day witnessed approximately 35 percent of all IPv6 traffic in native form. Typically, just 5 percent of IPv6 traffic is native, while the rest of it is tunneled. The increase of native IPv6 is a good sign for the technology's long-term potential.

Network service provider Akamai also published the its results during World IPv6 Day, further solidifying the event's success. On June 7, the day before World IPv6 Day, the network experienced approximately 78 IPv6 transmissions per minute. On World IPv6 Day, the network handled 458 hits per second. Akamai's results exposed a few issues with latency for IPv6 users, but nothing critical. Overall, North America proved to be the most active region, in terms of IPv6 use, on Akamai's network during the event.

The FierceTelecom report said the IPv6 usage results are not overly impressive, especially compared to IPv4 transmissions on the same networks. However, it is important to note that IPv6 will likely jump to approximately 1 percent of all internet traffic during the next six months, Winters told the news source. While 1 percent seems fairly small, it represents significant growth in transmission density that Winters believes will rise faster than many experts originally anticipated.

IPv6 readiness could be especially important in the data center. According to a recent Data Center Knowledge report, most facilities must prepare for IPv6 by managing their efficiency technologies, not just their networks. So many data center cooling, lighting and monitoring systems that support facility efficiency are connected to the internet that IPv6 readiness could prove to be a critical part of data center design, the report said.
