  2. Short Term Scenario:IP/MPLS and Ethernet over NG-SDH and OTH Core ODXC (L1SC) (WDM point-to-point) CoreNetwork Metro PoP: Router (L3SC) Switch (L2SC) ODXC (L1SC) NOBEL Application Server Metro Network Hub-Node Switch (L2SC) Hub-Node ADM, OADM GbE – 10 GbE PSTN SW STM-N, ODU Access Node: Switch (L2SC) Access Node: ADM, OADM POTS Access Network PABX L3 and L2 Services (IP/MPLS and Ethernet) L1 Services (NG-SDH, ODU) Customers (e.g. Residential, SOHO, etc) Customers (e.g. Corporate, ASP, ISP) (NG-SDH Services = SDH + GFP + LCAS)

  3. Core Nodes: Layer 1 switching: ODXC (SDH and/or ODU switching fabric) Metro PoPs: Layer 1 switching: ODXC (SDH and/or ODU switching fabric) Layer 2 switching: Ethernet switches Layer 3 switching: IP/MPLS Hub Nodes: Layer 1 ADMs, OADMs Layer 2 switching: Ethernet switches Network Services L3 and L2 via Ethernet (L2 switch access nodes) L2 (Ethernet/GFP) over SDH circuits (ADM) L1 (SDH circuits and ODU) (OADM) Short Term Scenario:IP/MPLS and Ethernet over NG-SDH and OTH

  4. Medium Term Scenario:IP/MPLS and Ethernet over ASON (SDH+OTN) Transparent CoreNetwork Core OXC (L1SC) BoD ? Metro PoP: Router (L3SC) Switch (L2SC) ODXC / OXC (L1SC) NOBEL Application Server Metro Network Node integration ? Hub-Node Switch (L2SC) ODXC / OXC (L1SC) Hub-Node ADM, OADM GbE – 10 GbE PSTN SW STM-N, ODU and Lambda BoD ? POTS Access Node: Switch (L2SC) Access Node: ADM, OADM Access Network PABX BoR L1 ASON Services (NG-SDH, ODU and Lambda) L3 and L2 Services (IP/MPLS and Ethernet) Customers (e.g. Residential, SOHO, etc) Customers (e.g. Corporate, ASP, ISP) Overlay Model

  5. Core Nodes: Layer 1 transparent switching: OXC (optical switching fabric) Metro PoPs: Layer 1 switching: ODXC (SDH and/or ODU switching fabric) and OXC (lambda switching fabric) Layer 2 switching: Ethernet switches Layer 3 switching: IP/MPLS Hub Nodes: Layer 1 ADMs, OADMs Layer 2 switching: Ethernet switches Network Services (permanent, soft-permanent, switched) L3 and L2 via Ethernet (L2 switch access nodes) L2 (Ethernet/GFP) over SDH circuits (ADM) L1 (SDH circuits, ODU and Lambda) (OADM) Bandwidth on Demand (e.g. access vs metro, metro vs core) Bandwidth on Request (e.g. Customer) Medium Term Scenario:IP/MPLS and Ethernet over ASON (SDH+OTN) Overlay Model

  6. NOBEL Long Term Scenario: GMPLS Transparent Core Network Core GMPLS OXC (Lambda SC) Metro PoP: GMPLS LSR (L1SC-L2SC-L3SC) Application Server Metro Network Hub-Node GMPLS LSR L2SC, L1SC Access Node: E-LSR Access Node: E-LSR Access Network Customer with E-LSR L1 Services L3 and L2 Services Customers (e.g. Corporate, ASP, ISP) Peer-to-peer Model Customers (e.g. Residential, SOHO, etc)
