SURFnet and GigaPort
SURFnet5 infra: lambdas and fibers
GigaPort NG Network infra: fibers only
Lessons learned

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)…

Lessons learned

SURFnet5 topology

SURFnet5: lambdas and fibers
15 large PoPs
thirty 10G lambdas
Resilience on IP level!
150 institutes
102 institutes connected at Gbit/s level
(HSDrenthe = #100)

GigaMAN concept: ring structure
Ring starts and ends at existing SURFnet PoP
Client locations on the ring are added like “pearls on a necklace”
PoP To Core To Core Institution Institution Institution Institution

FttD concept: Same duct, different pair One fiber pair: 1 Gbit/s Dormitories University in house UTP 10-100 Mbit/s SURFnet in house UTP 10-100 Mbit/s in house UTP 10-100 Mbit/s

Lessons learned

Paradigm shift Next generation networks cannot be a simple extrapolation of the existing networks

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

(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

Firm belief: All fixed infra will move to fiber

Market: Unequal spread of infra Pictures: Yuri Demchenko

(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

Lessons learned

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)

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

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

Price ranges dedicated fiber infra In Euro/meter € 0 € 10 € 20 € 30 € 40 € 50 € 60 rural urban 48 4 24 96 strands

New ways for the network to fail…
