Giga. Port results • Realization exceeds plans within budget – SURFnet 5 10 Gbit/s based network up&running – Native support of IPv 4 and IPv 6 – Multicast support based on PIM-SM – 60% of customers connected via Gigabit Ethernet – 20, 000 students via 10/100 Mbit/s Ethernet – Congestion free global Internet connectivity – Nether. Light: major hub internat. lambda network – Development of market for managed dark fiber • Partnership contribution higher than estimated TERENA workshop on NREN-controlled fibers – København – October 24 th, 2003 4

Giga. Port NG Network Bsik proposal • Consortium of 50 partners on demand / research side – SURFnet is the executive organization • Submitted in Bsik program – decisions for grants expected October 2003 • Project focuses on implementation nextgeneration network and includes research on networks TERENA workshop on NREN-controlled fibers – København – October 24 th, 2003 14
(1) SURFnet 6 overview • Congestion free transparent end-to-end IP transport as of 1 July 2005 – unicast and multicast; IPv 4 and IPv 6; all at wire speed – 1 Gbit/s, 10 Gbit/s and beyond • Lambda services to eventually all connected organizations • Additional functionality after 2005 • 150 - 200 connections • Layer 1: DWDM equipment • Layer 2: Ethernet equipment • Layer 3: Small routed core at approx. 2 locations TERENA workshop on NREN-controlled fibers – København – October 24 th, 2003 15

Fibers @SURFnet • *Managed* dark fiber • IRU for 15 years (upfront payment and maint) • October 2003: ± 3000 km managed dark fiber • In 2004: last fibers routes added to be “selfsupporting fiber-wise” (e. g. Wageningen, Maastricht and Den Haag) TERENA workshop on NREN-controlled fibers – København – October 24 th, 2003 20
Problem areas • • • Synchronization of buying power Specific position of city councils Law issues Infrastructure public. . . or not. . . Protesting operators Cook book: http: //gigaman. gigaport. nl TERENA workshop on NREN-controlled fibers – København – October 24 th, 2003 21
SURFnet’s advice to local/city governments • The government is expected to organize its internal matters efficiently and buy rationally • Buying power with city government leaves government in a safe “launching customer” role • No market disruption as long as the line is not crossed between “take care of your self” and “delivery to third parties” is not crossed TERENA workshop on NREN-controlled fibers – København – October 24 th, 2003 22
