N-Wave Engineering Update

This report provides an update on the N-Wave Engineering progress as discussed during the Stakeholders Conference in Boulder, held on May 22, 2012. Key highlights include the full meshing of the core network for high availability, designed primarily for high-volume data flows with a capacity initially at 10G and upgradeable to 100G. Various critical connectivity enhancements have been implemented, including the use of DWDM for core circuits, Layer 2/3 VPNs for Ethernet connectivity, and the establishment of multiple Layer 3 Virtual Routing and Forwarding (VRF) structures for management and traffic segregation.

  9. Hawaii Connectivity

  10. MPLS VRF Structure • Layer 3 VRF- Virtual Routing and Forwarding • Separate routing tables keeps participant traffic segregated • Management – Default VRF • Private VRFs • RDHPCS • CLASS and CLASS-DB • NOAA (OAR) Wide VRF

  11. Layer 2 Connections • WOC/NCEP– Data replication from Gaithersburg to Boulder • SWPC Boulder access to NCEP Supercomputer • Fairmont Internet access • SOC/Fairmont to Silver Spring NOC

  12. Layer 2 VPN

  13. MPLS Expansion • Extending MPLS out to the aggregation routers • Simpler to configure and maintain • More resilient • Single Layer 3 peering at Aggregation sites • Layer 2 redundancy • Cisco to Juniper MPLS interoperability

  14. Uptime • Network operational on Jan 1st 2011 • Core Network uptime - 100% • For a Participant dual homed to core • 100% Uptime • Fully meshed design
