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) pre-GDB – Networking, 10st January 2017 -- Bruno Hoeft

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 CERN R-ig-II R-grid2 R-grid145 FS R-grid6 … R-grid3 FS 10 Gbps 40 Gbps 100 Gbps Bruno Hoeft

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 pre-GDB – Networking, 10st January 2017 -- Bruno Hoeft
