Preview of The Evolution of NREN Architectures Session at 2018 Global Summit
By Rob Evans (Jisc), Lars Fischer (NORDUnet), Jac Kloots (Surfnet), Garreth Malone (HEAnet), David Wilde (AARNet), John Moore (Internet2), and Patty Giuntoli (ESnet)
Research and education is changing, and the providers of research and education (R&E) networks have to adapt to keep up with those changes. The use of cloud services, high performance computing, interactive applications and the provision of services on top of the network, virtualised where possible, mean that the operation of R&E networks is changing as fast as it ever has before, even if our users believe that there’s nothing new in networking.
In this session at the Internet2 Global Summit meeting, you will be able to hear from the architects of seven national research and education networks (NRENs): AARnet in Australia, ESnet in the U.S., HEAnet in Ireland, Internet2 in the U.S., Janet/Jisc in the U.K., NORDUnet in the Nordic countries (Sweden, Norway, Finland, Denmark, and Iceland), and SURFnet in The Netherlands.
We will talk about how changing user requirements are leading to changes in network architectures. We plan on the keeping the talks brief to allow for engaging and lively corridor conversations during the rest of the meeting.
Some of the topics you can expect to hear from our group include:
- how automation and orchestration is increasingly a requirement to provide the agile services that keep us ahead of the commercial market.
- how disaggregation can provide the flexibility to adapt at all layers of the network.
- how inter-operation between NRENs (and regional networks) can enable global service delivery that is impossible via any other provider or mesh of providers.
- how to tie the architectures of NRENs, regional networks, and campus networks together to deliver services to our end users.
As old-time perl scripters will remember – “there’s more than one way to do it, but sometimes consistency is not a bad way either.” NRENs must work for their own customers, but in a world of global research and education, consistency of services is not a bad way either.
