June 6 marks World
IPv6 Day, where many Web companies from around the globe will officially enable
Internet Protocol version 6 for their products and services.
IPs are the primary communication protocol for relaying
datagrams, or network packets, across a computer internetwork. So, why is this
important? Because IPv6 was created with the intent to succeed IPv4, the
protocol that currently drives the majority of Internet traffic, and the launch
day will officially signal that major Internet businesses, including Facebook,
Google and Bing, are ready to get behind IPv6.
If you’re curious about the differences between IPv6 and its
version 4 counterpart, the former specifies a new packet format that minimizes
header processing by routers, offers larger address space, multicasting,
stateless address autoconfiguration, greater mobility and privacy and more. However,
at its base, version 6 isn’t much more than an extension of version 4, and many
transport and application-layer protocols will require little-to-no change to
operate on the newer IP, although there are some exceptions, such as those app
protocols that embed Internet-layer addresses.
Load balancer and application delivery controller
KEMP Technologies has announced that its LoadMaster LM-3600 load balancer
technology has been tested and validated as performing with equal success using
either IPv4 or IPv6 at Layer 7. This means that the load balancer is able to
provide a high-performing application delivery controller (ADC) solution that
will continue to work identically for companies as the transition to IPv6
becomes more widespread.
The tests were conducted by Broadband Testing and found that
KEMP load balancers can support high throughput (just under 3 Gbps) for high
availability of business-critical Web apps at both Layer 4 and 7 using IPv4 or
IPv6, and it offers seamless migration to IPv6 load balancing without forcing
companies to accept any performance loss.
This is important because, eventually, deploying IPv6 will be
the only sustainable solution to IPv4 address deletion, more so for apps that
will be consumed on mobile devices than anything else.
Thus, KEMP has worked to
ensure transparent migration for business that will need to access their assets
over IPv6 networks in order to maintain performance, predictability and
reliability of network services. And now those efforts have been validated
using real-world traffic scenarios that pushed the LoadMaster 3600 until packet
loss occurred. In some of the tests, IPv6 throughput even outpaced that of IPv4.
