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
