7. further Development Generally Fibre platform
Development of X-WiN is carried out on economical criteria
New services and technologies must be financed by allocation of costs
Considerable network upgrade realised between 2012 and 2016
Fibre platform
No significant changes expected before 2025
Optical platform and IP-platform
Adoption of 400Gbps and 1 Tbps is expected
External peering will be upgraded (GÉANT, Peering) accordingly
Deployment of SDN, currently too indistinct, might be consider in future (under observation)
DoS-Mitigation at IP-platform is an important DFN-Service
Deployment of new aggregation platform planed in 2017 (router at PoP)

CERN (T0)
FR-CCIN2P3 (T1)
IT-INFN-CNAF (T1)
NL-T1 (T1)
Poland (T2)
FZU (Prague) (T2)
LHCOPN
Current 2 X 10Gbps  upgrade planned
to 4 x 10Gbps or even higher capacity
shared LHCONE + Internet
Current 2 X 50Gbps  upgrade to 2 X 100Gbps  higher upgrade will require deployment changes

9. Network of DE-KIT  2017 DE-KIT local: Storage Workernode
WAN
DE-KIT local:
Storage
multiple 100G connections to the Storage
Possibility of Scalable upgrade
Workernode
Each WN 10Gbps
each rack connected with a max. overprovitioning of 1:2
R-ig-I

10. summary DFN DE-KIT / GridKa
Conservative approach (routed supper core network)
Throughput upgrade as required (and costs covered)
DE-KIT / GridKa
Local
Storage  multiple 100G Connections + scalable upgrade
Workernodes  max overprovitioning of 1:2
LHCOPN
2*10Gbps current
Upgrade planned
LHCONE
2*100Gbps physical
Upgradable to required capacity
Point-2-Point
to supplement LHCONE routed VRF with bandwidth garantied p2p connection of dedicated big WLCG centers
Leave LHCOPN in place  surved LHC well  may be upgrades as required
Extend LHCONE  include sites as required  and upgrade to apropriate capacity
Supplement LHCONE with p2p links between dedicated „big“ WLCG centers
Sites shall keep the focus on deploying their lan capacities and wlcg services
