GigaPort results

• Realization exceeds plans within budget– SURFnet5 10 Gbit/s based network up&running– Native support of IPv4 and IPv6– 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– NetherLight: major hub internat. lambda network– Development of market for managed dark fiber

• Partnership contribution higher than estimated

SURFnet network generations

• SURFnet1: DECnet Phase 4 over public X.25• SURFnet2: DECnet and IP over private X.25• SURFnet3: IP and X.25 over leased lines• SURFnet4: IP over ATM over SDH over

glas/koper -> IP over SDH over glas• SURFnet5: IP over DWDM/glas

• Moving towards simpler architectures (KIS)…

GigaPort 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 next-generation network and includes research on networks

15TERENA workshop on NREN-controlled fibers – København – October 24th, 2003

(1) SURFnet6 overview

• Congestion free transparent end-to-end IP transport as of 1 July 2005

– unicast and multicast; IPv4 and IPv6; 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

18TERENA workshop on NREN-controlled fibers – København – October 24th, 2003

(1) Building blocks for SURFnet6

• Managed dark fiber infrastructure (will be extended with new routes)

• More than 25 co-location facilities

• Operations

• Upstream and peers

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 “self-supporting fiber-wise” (e.g. Wageningen, Maastricht and Den Haag)

21TERENA workshop on NREN-controlled fibers – København – October 24th, 2003

Problem areas

• Synchronization of buying power• Specific position of city councils• Law issues• Infrastructure public... or not...• Protesting operators

22TERENA workshop on NREN-controlled fibers – København – October 24th, 2003

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
