The ISOC Fellowship Program to the IETF, a new program
launched by the Internet Society, is making it possible for
technologists from developing countries to become more
involved in the IETF by attending meetings in person.
Fellows attending IETF 67 included (from left) Azael
Alcantara (Mexico), Alfred Prasad (Fiji), and Laupue
Raymond Hughes (Samoa).

Fellowship Program
Increases Access to IETF
The experience proved meaningful. According to Azael,
“after having met the people involved in the IETF, the
authors of drafts and RFCs, and the relations among the different WGs and the other organisations, it is going
to be very useful to reinforce what I do at work, to increase my participation in the mailing lists, and to stimulate
myself to write an RFC with others.”
A small selection committee composed of individuals with extensive knowledge of the IETF will evaluate
applicants against selection criteria and make fellowship recommendations. Complete information about the
program, including how to apply, can be found at http://www.isoc.org/educpillar/fellowship/.

Plenary Report, continued
The most common forms of unwanted traffic began as
worms and viruses that are designed to wreak havoc on the
network and that have evolved to include self-propagating
malware, which compromises hosts and enables command
and control infrastructure, as well as service platforms that
facilitate malicious activity.

Data suggests that current trends in the growth of routing
and addressing are not scalable in the long term due mainly
to the rapid growth that resulted from multihoming and traffic
engineering. Unfortunately, when it comes to routing, IPv6
is not significantly different from IPv4; it shares many of the
same properties and scaling characteristics.
