• Conclusions and the Importance of
Why R&E Networks?
• Large data flows and other special
requirements on such flows
• The ability to examine and develop new
network capabilities
• Providing platforms to support network
• Provide a vehicle for collaborative
development of network applications
Why R&E Networks? Large Flows
• Historically, research traffic has challenged
the capabilities of commodity networks
– Flows can be very large
– They can also require significant traffic shaping
• Flows in the commercial internet tend to be
fairly small – they typically lag behind the
research community
• Research Projects like the LHC, LIGO, and
DUSEL require significant data transfers
across multiple R&E networks
• The Large Hadron Collider
• Huge data flows processed and sent to Tier 1 sites around the
world, and then on to Universities (Tier 2 and 3 sites) and and
other Labs, typically connected through R&E networks.
• A participating university might require data flows of 10 Gbps for
hours on end.

Why R&E Networks?
• Providing platforms for research on
networking and collaborating with network
researchers on protocols new developments
– Providing infrastructure for projects like the GENI
(Global Environment for Network Innovations)
• Perhaps most importantly knowledge transfer
between participants and keeping abreast of
the changing requirements of the research
and education community
Collaboration From The Beginning
• Before the Internet became an essential resource in
our lives, networking was primarily dependent on
proprietary protocols
– BITNET was an example
• From the early days of the Internet, however, open
protocols became the norm, and building such
networks depended on collaboration within the R&E
– In the US, the IP network was dependent on research
groups and universities (and later corporations) forming
regional networks and connecting those networks to a
backbone, which was then interconnected to other networks
• Indeed, the “Internet” means the interconnection of
Collaboration From The Beginning
• The NSF in the US was essential in this development
• The same basic hierarchies continue today, although
in a much more complicated network universe
• Moreover, the fact that there is no central authority
over the Internet means that networks must work
together to provide services – that is especially true
in the R&E world.
• This begs the need for even greater collaboration
between researchers, educators, and networks at all
levels – campus, state, regional, national, and
Technology and Building Networks
• In the early days of networking, R&E networks typically leased
circuits from telcos and controlled just the routers at the IP layer
• This was true, for example, for Internet2 and its first network,
called “Abilene”
– The Partners in that project were the universities, regional networks
then called gigapops, and the formation of Internet2 as an
– It also included three very important commercial partners: Cisco,
Nortel, and Qwest! It became clear that collaborations between
the R&E network community had to extend to the commercial
• In today’s world, however, it is typical for R&E networks to
control all layers in the protocol stack
– That means from the fiber up to higher level protocols!
Building Networks
• Major Questions:
Who are the participants in the network?
Where are the connectors to the network?
What physical medium is available to connect those sites?
Who will manage the network?
• Layer 0
– What fiber is available, and how is it available – long term
IRUs, for example?
– Do you have to build your own fiber, and what partners might
you do that with?
– What are the properties of the fiber – types, hut spacing, etc.
Building Networks, continued
• Layer 1
– Is support for multiple waves needed on the network?
– What is the availability of wave equipment for the fiber footprint?
Hut spacing, for example
– What are the regeneration requirements? How often does drop
add have to be done, for example? What about OEO versus long
optical paths?
– Do your connectors need dedicated circuits for special
– What are the bandwidth requirements? 100Gbps?
– Do sub-wave circuits need to be supported?
• Layer 2
– Is a separate layer 2 switching component needed or can it be
incorporated at layer 3?
– Do connectors expect dedicated vLANs, for example?
Building Networks, continued
• Layer 3
– Are there special routing requirements?
– Do lower layers need to be supported at the IP layer? For
example, MPLS?
• Management and Operations
– Who will manage the network?
– How will connectors interface with management operations?
• The KISS principle is important to remember in all these
Building Networks, continued
• Interestingly enough, the R&E community in the
United States went through this process within the
last two months as part of a proposal for an
expanded network.
• The process involved a collaboration between many
different entities and partners
Regional Networks
Other Collaborations formed from Regional Networks
Internet2 and NLR
Commercial providers like Cisco, Ciena/Nortel, Juniper, Infinera,
Level3, etc.
• The process was a huge effort that could not have
been done without collaboration!
Much More than Just a Network!
• It’s what users, and in particular, researchers can do
on the network!
• The organization provides the vehicle, and indeed the
encouragement, to develop new applications and
uses of the network.
• Consider the recent IDEA awards at the Internet2
Spring Member Meeting.

controller designed primarily for a high performance network

• Research and education networks provide a vehicle
to support essential collaborations:
For the research community
To develop new networking concepts and ideas
For the development of new applications
For education on a world-wide basis
To encourage collaborations in many different disciplines
• Research and education networks require
collaboration on many different levels – between
educational institutions; other regional, national, and
international networks; and with both corporate and
governmental entities to provide advanced services
to the R&E community!
