EE 555 Broadband Network Architectures 2.6 Optical WANs R&E Case Studies NLR - Background NLR Background • National LambdaRail is a non-profit corporation created (2003) by a consortium of major US R&E networks in conjunction with CISCO Systems Identified the need for experimental and research oriented network(s) Research networking AND network research • Motivated by CENIC CalREN dark fiber build-out in California, took advantage of dark fiber price trough (minimum?) to acquire national footprint 20yr IRU’s • Partnered with CISCO to deploy 40 lambda DWDM network 2 usc-den-ee555-silvester-spring2009

Why own/operate the fiber? • Future-proof against technology advances • Isolate R&E networks from carrier pressures and restrictions • Control of the acceptable use policy • Allow maximum flexibility to configure networks and services • Develop optical networking and engineering skills in R&E community • Allow for experimentation at all levels down to the glass 3 usc-den-ee555-silvester-spring2009 NLR Infrastructure (June 2006 NLR owned fiber* NLR WaveNet, FrameNet & PacketNet PoP NLR Infrastructure (June 2006) NLR WaveNet & FrameNet PoP NLR WaveNet PoP STAR SYRA BOIS PORT SEAT CHIC SALT KANS PITT WASH CLEV NEWY DENV SUNN OGDE RATO SAND DALL TULS PENS PHOE LOSA ALBU ATLA RALE BATO HOUS ELPA SANA JACK * Fiber on the SAND-LOSA-SUNN path belongs to CENIC 4 usc-den-ee555-silvester-spring2009

NLR Services • Network of Networks Network of Networks – Multiple types of networks and services available • Main Services Main Services – WaveNet - point-to-point “lambdas” – actually these are currently point-to-point circuits consisting of concatenated (OEO) dedicated wave segments – FrameNet(s) – Dedicated and shared Ethernet based services – PacketNet(s) - IP based networks 5 usc-den-ee555-silvester-spring2009 NLR Infrastructure •O v e r 1 1 ,000 route miles (17,000 km) of fiber in backbone plus much more in RON’s • Owned Fiber: 20-yr IRUs • Layer 1 Optics: Cisco 15808s and 15454s supporting up to 40 10 Gbps lambda, (2009 being upgraded) (OC 192 or 10GE (OC-192 or 10GE) • Wavelengths available for experimental or production networks • Layer 2: Cisco 6509 switches for Gigabit Ethernet • Layer 3: Cisco CRS-1 routers for IP 6 usc-den-ee555-silvester-spring2009
