Introduction
JRA1 T1 Status: Carrier Class Transport Network Technologies Layer 2 routing Ethernet over MPLS Synchronous Ethernet Next step: Further study and testing -OAM. - Protection & Restoration. - Multi-domain implications. - Cost-effectiveness. Ethernet MPLS-TP PBB-TE NG-OTN Comprehensive study and demonstration NG-IP NG-OTN Control Plane (GMPLS) Control Plane (GMPLS) Deliverable DJ1.1.1
JRA1 T2 Status: Photonic Switching & Experimental Photonic Facilities Next Step ROADM Data Centre WSS PIC Impairment aware Control Plane Optical Components Optical amplification Optical add/drop Photonic fiber switches Wavelength channel spectrum Optical Packet and Burst Switches Forward Error Correction (FEC) All Optical 10+ years if ever! Alien Wave 100G Data Centre Validate results through practical tests.
JRA1 T3 Status: Federated Network Architecture Federated Network Architecture Base Model The building blocks End user Service Layer Service Layer Operation Layer Infrastructure Layer Service A Provide by end users Intra-federated Intra-federated Service A Intra-federated Tool A NE Network Element Intra-federated Intra-federated NOC A Operation Center Model A: Simple architecture Model B: Complex architecture Next step: Model A & B Prof of Concept CPE NREN 1 NREN 4 NREN 5 NREN 1 NREN 7 NREN 5 NREN 6 NREN 7 Federated Operation CPE

PoC and Prototype studies
Current Common Network Technologies IP MPLS Ethernet SDH OTN DWDM Photonics Cost Power SOLUTION - Process traffic at the lowest possible layer
Current Common Network Architecture Network Infrastructures NMS Manpower Communication IP NMS CLI IP Department C A PKT/ TDM NMS GUI Transmission Department WDM NMS GUI B Fragmentet Network Architecture Wasting ressources
Current Common Multi Domain Network Architecture Client I/O Back to Back Virtual Circuits Domain 1 Domain 2 Passive Local access ODF Change = Truck roll Fiber Patch RFS = 12 to 16 Weeks
Optical Transport Network (OTN) Ethernet IP SDH Optical Channel Layer Optical Multiplex Section Layer Optical Transmission Section Layer The next big thing OTN The advantages of OTN compared to SDH Transparent Client Signals Better Forward Error Correction Better scalability Increased number of Tandem Connection Monitoring points Physical Medium - Fibre
Next Generation OTN Ethernet OTN? PKT Single Converged Transport System Digital SDH Fibre Channel ESCON λ and sub-λ networking Coarse granularity Analogue λ λ WDM λ λ Switching Multiplexing Grooming Transparent pass through Well-suited to backbone environments
The New Dawn of Network Architectures PoP A PoP B NMS GMPLS NMS IP/OTN/WDM IP/PKT/WDM IP/PKT off Loading Metro/Regional 0 Gbps 10 Gbps Dynamic Adaptive Switching 100% Packet Peering IPT Core Backbone 1Gbps 100Gbps 100% Circuit
The New Dawn of network architectures - Federation NREN 1 Federated Network Architecture Example OTN Switch NREN 5 Federated Operation CPE NREN 7 NREN 1 IP (P) Router NREN 6 IP Peering NREN 4 NREN 5 CPE NREN 7 IP Transit 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 IP intelligence to the edge Centralized IP Core (IP-T and Peering) OTN for Multi-Domain Interconnection Use Federation where it make sense IP Off Loading CCTNT for Metro and access networks OTN Based Transport Layer Vertical Control Plane Integration DWDM Mesh Base Layer Uniform Network Architecture will not fit all
