1. Erik Radius Manager Network Services SURFnet, The Netherlands Joint Techs Workshop Columbus, OH - July 20, 2004 GigaPort Next Generation Network & SURFnet6

2. GigaPort/SURFnet5 conclusions SURFnet5 is still world leading network, but… –NREN users need new services that current networks cannot support –Data communication infrastructures will become part of the Grid and will be integrated in scientific instruments –Hybrid networks delivering IP and Lambda Services can meet user demand within budget constraints, using IP-GE- lambda + overprovisioning + KIS

3. Why Lambda Services? Provides excellent quality on point to point connections at very high speed Protects the routed network Enables demanding applications to make use of the infrastructure in an economically sound way

4. SURFnet’s new Industry Partners (2004-2010) Optical equipment Ethernet equipment Network management equipment Routing equipment Installation services Maintenance services

5. SURFnet6 will be based on dark fiber Over 4000 km fiber pairs available today; average price paid for 15 year IRUs: 7 EUR/meter per pair Managed dark fiber infrastructure will be extended with new routes, approx. 1000 km more to be ready for SURFnet6 See also http://www.surfnet.nl/organisatie/netwerk/flash/kaart.htmlhttp://www.surfnet.nl/organisatie/netwerk/flash/kaart.html

7. SURFnet6 overview Realization of a next generation hybrid network with seamless end-to-end communication: –Based on customer-owned managed dark fiber –IP Services and Lambda Services over a single transmission infrastructure managed, via a single control plane –Multi-domain networking –Ethernet services as part of the WANs –Intelligence of networks and the associated responsibilities at the edges Paving the way to a ubiquitous and scalable Services Grid

8. SURFnet6’s IP Services IPv4 and IPv6 connectivity: –Unicast –Multicast Small routed core in Amsterdam at two distinct locations Congestion-free (lambda services aid to this!) Resilient

9. SURFnet6’s Lambda Services Lambda Services: Light Path provisioning Enables users or applications to make, or signal for, service level changes to their layer 2 paths Characteristics: –Flexible –Economical –Reliable –High-speed, i.e. 1G or 10G Light Paths aren’t constrained by traditional framing, routing, and transport

10. So, what are Light Paths? A Light Path has the following characteristics: –No packet re-ordering –No jitter –No drops due to congestion –Known end points A Light Path can therefore: –Bypass firewalls between trusted parties –Enable the use of alternate network or transport protocols

13. Users: Three categories Lightweight users doing browsing, mailing, home use –Need full Internet routing, one to many Business applications, multicast, streaming –Need VPN services and full Internet routing, several to several Special scientific applications, computing, data grids, virtual- presence –Need very fat pipes, limited multiple Virtual Organizations, few to few This slide courtesy of Cees de Laat BW requirements #users#users C B ADSL GigE  A ≈ 20 Gb/s  B ≈ 40 Gb/s  C ≈ 100 Gb/s A
