JRA1 T1 Status: Carrier Class Transport Network Technologies Next step: Layer 2 routing CCTNT Carrier Class Transport Network Technologies • Further study and testing • - OAM. • Protection & Restoration. • Multi-domain implications. • Cost-effectiveness. Ethernet over MPLS Synchronous Ethernet Ethernet Comprehensive study and demonstration MPLS-TP NG-IP PBB-TE NG-OTN Control Plane (GMPLS) NG-OTN Control Plane (GMPLS) Deliverable DJ1.1.1
JRA1 T2 Status: Photonic Switching & Experimental Photonic Facilities • Next Step Data Centre ROADM WSS PIC Impairment aware Control Plane 100G • All Optical 10+ years if ever! • Validate results through practical tests. Data Centre Alien Wave • Optical Components • Optical amplification • Optical add/drop • Photonic fiber switches • Wavelength channel spectrum • Optical Packet and Burst Switches • Forward Error Correction (FEC)
JRA1 T3 Status: Federated Network Architecture Base Model – The building blocks Model A: Simple architecture Model B: Complex architecture End user Service Layer Service A Provide by end users Next step: Model A & B Prof of Concept Intra-federated Service A Intra-federated Service Layer Intra-federated Intra-federated Service A NREN 1 NREN 5 Federated Operation CPE Operation Layer X X X X X NREN 7 NREN 1 Federated Network Architecture Intra-federated Intra-federated NREN 6 Intra-federated Tool A NOC A Operation Center X X CPE NREN 5 Infrastructure Layer NREN 4 NREN 7 NE Network Element
Status: JRA1 T4 - Current and Potential uses of Virtualisation Proof of Concept and Prototype - Integrated virtualisation approach Requirement Analysis Implementation (Integration) Design and planning JRA1 T4 Study and analysis Deliverable DJ1.4.1 Deliverable DJ1.4.2 NEXT Step SAs JRAs NAs GENI AKARI AutoBahn 4WARD Federica Phosphorus Manticore Virtualisation Services and Framework Study Virtualisation Services and Framework incl.

Current Common Multi Domain Network Architecture Client I/O Back to Back Virtual Circuits Passive Local access X Domain 2 Domain 1 ODF Change = Truck roll X Fiber Patch RFS = 12 to 16 Weeks
Optical Transport Network (OTN) The advantages of OTN compared to SDH IP OpticalChannelLayer The next big thing OTN OpticalMultiplexSectionLayer Ethernet Optical Transmission SectionLayer SDH Physical Medium - Fibre Transparent Client Signals Better Forward Error Correction Better scalability Increased number of Tandem Connection Monitoring points
Next Generation OTN ? Single Converged Transport System and sub- networking • Coarse granularity • Switching • Multiplexing • Grooming • Transparent pass through PKT Ethernet OTN X X SDH Digital Fibre Channel ESCON WDM X Analogue Well-suited to backbone environments

The New Dawn of network architectures - Federation NREN 1 Federated Network Architecture Example NREN 5 Federated Operation OTN Switch CPE NREN 7 NREN 1 IP (P) Router NREN 6 CPE IP Peering NREN 5 X X X X X X NREN 4 NREN 7 IP Transit X X X • Interconnections provided by individual domains e.g. wavelength or sub waves • Demarcation Nodes (OTN and IP) provided by Virtual operator • NOC handled by the Virtual operator
Summary OTN for Multi-Domain Interconnection IP intelligence to the edge Use Federation where it make sense Centralized IP Core (IP-T and Peering) OTN Based Transport Layer IP Off Loading Vertical Control Plane Integration CCTNT for Metro and access networks Uniform Network Architecture will not fit all DWDM Mesh Base Layer
