N-Wave Design Review
• Designed primarily for high-volume data flows
• Initially 10G mesh, 100G upgradeable
• Internet2/NLR DWDM waves for core circuits
• Core network fully meshed for high availability
• Waves on various R&E RONs for access to core
• Ethernet only with MPLS – L2/3VPNs
• Instrumentation/test servers at node and site

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

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