Bits-n-Bites first took place during IETF 84 and has since been
organized during each IETF as an integral part of the agenda. In
addition to showcasing technology from our sponsors, the goal of
Bits-n-Bites has been to provide insight into how IETF contributions are
being used and deployed on a daily basis around the globe. Running code
is very important to the IETF, as discussed in our previous article.
The demonstrations and testing that we do in Bits-n-Bites not only helps
provide feedback to improve work but also helps to stimulate future
work that is essential to the growth and continued success of the
Internet. Given the charter of the IETF and the nature of the work that
takes place during a typical IETF, Bits-n-Bites is an excellent venue to
display and demonstrate the same.
The latest installment of during IETF 86 in Orlando, Florida hosted
by NBC Universal and Comcast Bits-n-Bites included many interesting
demonstrations, following is a recap of what was exhibited.
First, Comcast through support from some key manufacturers Arris,
Broadcom, and Cisco made available a functioning DOCSIS 3.0 broadband
network, which was fully IPv6 capable, that provided the foundation for
many of the other demonstrations that were unveiled during the event.
The DOCSIS network and services that were demonstrated are analogous to
what many Comcast customers use in their homes today. Arris solutions
were used to provide the critical broadband network while Broadcom
reference designs were used to demonstrate some new developments in
customer premise or home networking. Finally Cisco System Network
Registrar and Broadband Access Center provided the ever so critical
Next up were two excellent demonstrations of customer premises or home networking technologies. First up was HIPnet which
is work that is currently being developed in cooperation with Cablelabs
and was also presented during the IETF 86 HOMENET meeting. A Cablelabs
implementation built upon open source software was demonstrated along
with an implementation from Broadcom. For the first time ever both
implementations were tested and interoperated successfully during the
IETF 86 Bits-n-Bites event.
implementations that were also tested during the IETF 85 Bits-n-Bites
also returned to participate in Orlando. Several implementations were
tested and displayed, while connected to DOCSIS powered broadband
network, illustrating arbitrary topologies and source and destination
based routing. The value of this new technology is to enable
automatically configured networks for IPv6-based homes, while allowing
users to employ any number of routers, devices, ISP connections, and
allowing them to be plugged in arbitrary ways.
Buffer Bloat has been a
widely discussed topic across the community. Perhaps surprisingly,
increased buffering memory in routers may reduce networking performance,
particularly when the same routers serve both interactive applications
and background traffic. End users see this problem as impacting
broadband performance and increased response times. Working solutions
for the issue made an appearance during the IETF 86 Bits-n-Bites event.
Bloated and de-bloated streaming video, games, and interactive
communications provided evidence of running code that addresses the
challenges of Buffer Bloat.
Finally, there were many other key participants including Nominum
demonstrating their DNS and DHCP based solutions. In fact, Nominum’s DNS
solution was providing name resolution for the Bits-n-Bites broadband
network. Huawei returned again with a prototype of a virtual subset and
MPLS multiple topology technology. ISOC and ICANN were also present
providing important information about their organizations as well as
important background regarding the IETF as it relates to the Internet of
today and tomorrow.
