NLR - Background
• National LambdaRail is a non-profit corporation created (2003) by a consortium of major regional US R&E networks in conjunction with CISCO Systems and Internet2
• Identified the need for experimental and research oriented network(s)
• Research networking AND network research• Took advantage of dark fiber price trough (minimum?) to acquire
national footprint 20yr IRU’s• Partnered with CISCO to deploy 40 lambda DWDM network• Provides a range of services and networks to its members over
this infrastructure• Parallel effort by regional networks (RONS) has developed
similar capability for regional connectivity and distribution (e.g. CENIC, LEARN, FLR, …)

NLR Services
• Network of Networks • Multiple types of networks and services available
• Main Services• WaveNet (layer 1 or 1.5) – point-to-point “lambdas” –
actually these are currently point-to-point circuits consisting of concatenated (OEO) dedicated wave segments
• FrameNet(s) (layer 2) – Dedicated and shared Ethernet based services. Managed or best effort BW. Point-point or multi-point.
• PacketNet(s) (layer 3) – IP based network• Other Services
• Co-location, Remote Hands, Fiber IRUs

WaveNet Overview
• ETE circuits consisting of 10G or OC-192 wave segments
• Dedicated waves purchased by regionals or research projects
• Research waves, supported by CISCO, made available in support of approved research projects
• Quickstart waves (if available and preemptible for fail-over)
![Page 8: NLR Optical Capabilities John Silvester Special Advisor to CIO for High Performance Networking, Professor of EE, University of Southern California International](https://reader035.vdocument.in/reader035/viewer/2022070305/5514855b550346f06e8b4bde/html5/thumbnails/8.jpg)

FrameNet Overview
• National Exchange Fabric Service• NEF is a single VLAN and broadcast domain that extends to every
member • Allows members to arrange bi-lateral peerings• Every member gets a single 1GigE interface on their local NLR
FrameNet node for use of the NEF service• Point-to-point, Dedicated Bandwidth Service
• Members may order private VLANs to connect 2 different locations together, with dedicated bandwidth, for a circuit-like service
• Bandwidth available from 100Mbps to 10Gbps• Point-to-multipoint, Best Effort Service
• Members may order private VLANs to multiple locations for a circuit-like service
• Traffic on these VLANs carried through the network on a best effort basis

2007.08.26 CCIRN 2007 12
FrameNet
• Demand continues to grow, 10 GE interfaces and non-dedicated bandwidth are popular
• 86 Active VLANs, both dedicated and non-dedicated• Currently primary use of dedicated service is for
Layer 3 backup connections • Interest by research groups
• Collaborative multi-point projects• Experiment on non-dedicated service, understand utilization,
then migrate to dedicated service.• New Services being Developed, in particular on-
demand dedicated services• Adding FrameNet connection to MANLAN switch to
support layer2 connectivity to international networks

PacketNet Overview
• “Production” 10G Layer 3 IP network, fully operational
• Potential for several packet networks on different lambdas (or VLANS) can use virtual routing capability of CRS-1 or multiple router instances
• “Experimental” for research use to be made available when needed
