Overview

Overview

Why Research and Education Networks?

Collaboration From the Beginning

Technology and the Network

More than Just the Network

Conclusions and the Importance of Collaboration


Why r e networks

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 research

Provide a vehicle for collaborative development of network applications


Why r e networks large flows

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


Building research and education networks through collaboration

LHC

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.

The collider and CMS


Evlbi

eVLBI

Very Large Baseline Interferometry

Combine radio telescope images over wide baselines.

Perfect example of a project that can utilize dedicated network capabilities


Dusel

DUSEL

Deep Underground Science and Engineering Laboratory

Supports the underground needs of major scientific fields.

Getting the data to researchers all over the world depends on interconnecting R&E networks


Large data projects

Large Data Projects

Just three of many such projects currently underway

Note that the success of all of these projects, depends strongly on collaboration

And all depend on interconnected networks that depend on collaboration between networks and within R&E network communities

Why r e networks1

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

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 community

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 networks!


Collaboration from the beginning1

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 international


Technology and building networks

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 organization

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 sector.

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

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

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 requirements?

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 continued1

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 considerations!


Building networks continued2

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

Universities

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

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.

Echo Damp - a software multi-channel audio mixer and echo controller designed primarily for a high performance network

REDDnet – a large distributed storage facility for data-intensive collaboration among the researchers

Worldview – a hands-on network visualization system

Shibboleth – federated single sign-on software

Conclusions

Conclusions

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!
