BelWü facts – for politicians historiansYear Highlight
1987 Inauguration of BelWü, partially bridged IP and IP over X.25
1989 All universities in Baden-‐Württemberg connected to BelWü
1994 Full Mesh Network between universities with 2-‐34 Mbit/s
1998 Next technology step with 155 Mbit/s ATM connection
2001 Extension of the network to 1 Gbit/s (Cisco 12410/GSR), SRP/DPT rings with 2.4 Gbit/s und 622 Mbit/s
2006 First 10 Gbit/s connections
2010 Preparation of backbone network for 100Gbit/s-‐fahigen-‐Netz with Cisco ASR 9000. Self-‐operatedpassive DWDM, connectivity between major sites with multiple 10Gbit/s Ethernet connections
2013 First 100 Gbit/s connection

Innovation process so far
ZDN2015 -‐ Universität Tübingen 7
Driven by the “bandwidth race”
Backbone as continuous bottleneck
Researcher needs focused on regional
collaborations
Requirements indirectly
communicated via TA members
Dependency on external experts
Upgrade schedule slowed down due to rented BW lines

BelWü 2017+
Scientific Chairman
Vision, Flexible Network supporting the wide range of different regional collaborations, provide sufficient bandwidth, optimise for different traffic types, adopt emerging and new technolgies, …
BelWü NOC
Ever increasing complexity with fixed number of staff,Emerging (immature?) technology versus 24/7 availability
BelWü TA
Operation staff from the universities, paid to be conservative
Vendors
Push their specific solution as world best option J

Conclusions
• It is no longer enough for a research network to deliver just competitive bandwidth• Adoption of new technological trends and solutions in a 24/7 operational infrastructure is complex and a conflict area• bwNET100G+ solution approach
• Dedicated network infrastructure and test server with direct WAN access as playground
• Requirements and challenges from the practitioners• Integrated teams with researchers and operational staff• Validation will be based on technology capabilities but also onoperational and economic impact
• Proposed concepts from bwNET100G+ might not make it into production (“veto” position of operation)
