GigaPort Next Generation Network & SURFnet6 Erik Radius Manager Network Services SURFnet, The Netherlands Joint Techs Workshop Columbus, OH - July 20, 2004 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-GElambda + overprovisioning + KIS 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 SURFnet’s new Industry Partners (2004-2010) • Optical equipment • Ethernet equipment • Network management equipment • Routing equipment • Installation services • Maintenance services 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.html Metro fiber example (GigaMAN The Hague) 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 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 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 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 eEVN: European VLBI Network Data processing centre: 16 Gbps (2005) 1 Tbps (2010) Russia China USA 1-30 Gbps South Africa This slide courtesy of Richard Schilizzi <[email protected]> asymmetric star topology LOFAR • Many data collection points • Processing in Groningen • Large data sets distributed to many destinations in The Netherlands and abroad 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, virtualpresence – Need very fat pipes, limited multiple Virtual Organizations, few to few # u s e r s A SB ≈ 40 Gb/s SC ≈ 100 Gb/s SA ≈ 20 Gb/s B ADSL C GigE BW requirements This slide courtesy of Cees de Laat <[email protected]> Provisioning of IP Services External IP connectivity SURFnet6 Border Routers SURFnet6 Core Routers SURFnet6 Layer 2 / Layer 1 network Layer 3 functionality Non-SURFnet Customer Router Light Path Provisioning Operations Management Broker OGSA Applications Web service Layer 3 flow data collection and analysis Light Path Provisioning via Control Plane SURFnet6 Layer 2 / Layer 1 network Light Path SURFnet6 Routers Timelines SURFnet6 SURFnet6 will be a showcase for hybrid networks More information: http://www.surfnet.nl/ http://www.gigaport.nl/ Author’s e-mail address: [email protected]
