2 222 © 2004, Cisco Systems, Inc. All rights reserved. Aiken & Boroumand Why go back to the future ? Major advances and impact were made during ARPANET and early NSFNET years They had concurrent application and network R&D WEB took off in early 90’s due to existence of a network research infrastructure Mid to late 90s we saw production networks only No collaboration between applications and network/system researchers (ie. network researchers were estranged ) Merging and interdependence of applications, networks, systems, storage, content, … Dark Fiber now allows Morphnet concept of 1997

3 333 © 2004, Cisco Systems, Inc. All rights reserved. Aiken & Boroumand Why go back to the future ? - continued The need was never greater for a research infrastructure that concurrently supports application, network, system, & security research & interplay - e.g.: GRIDs, GRID applications, Middleware, Multi-media … Evolution of real end to end networks and protocols Real network data for monitoring & analysis of network traffic Scalable, Secure, highly available, resilient networks New applications, e.g. VOIP, NEES, sensor networks, gaming, on demand computing, HD multi-media collaborations … Adaptive networks Network management, control planes, provisioning Scaling of all aspects wrt speeds, users, networks, hosts,… EmuLabs and VPNs are good for proof of concept - but ::

Aiken & Boroumand We need Network Research Infrastructure like the NLR for the following types of research End to end Security (IDS,DOS,firewalls, crypto) QoS Predictability GRIDS and Mware TCP evolution & efficiency FAST, HS-TCP, XCP SuperJumbo frames Reliable UDP RDMA Alternative transport High Availability, resiliency, fail over,… Peering (Lambda, Frame, Packet) Provisioning VPNs, IP, L2,L1, Policy, security Routing and addressing Network Management Control Planes and signalling Merging of end systems and network provided storage, computing, …

Aiken & Boroumand Historical Perspective: NLR is the next big US Research and Education community initiative Every 5 years the US national research networking infrastructure evolves to the next level 19881993 2003 NLR Research universities ownership with significant Cisco investment Connecting new generation of ‘regionals’ and driving regional R&E fiber projects National footprint; own dark fiber, DWDM, Ethernet and IP services First ever ‘dual-mission’ experimental and production national scale infrastructure 1998 Abilene Higher education membership funded through UCAID Main Internet2 backbone connecting “GigaPoPs” National footprint; Qwest managed Sonet and wave service; own IP service Production traffic only vBNS NSF funded; part NGI program Originally connecting supercomputing centers and NAPs; later expanded to all research universities National footprint; MCI managed ATM and IP service Production traffic but had a separate “testnet” NSFnet NSF funded Connecting “regionals” which along with the backbone commercialized the Internet National footprint; leased circuits; own IP service Production traffic with limited experimentation

Aiken & Boroumand Network Tiers are a good idea - but … CENIC, NSF, and others advocating 3 types of “research networks” Good to focus on the 3 type of requirements – but > What we really need is ONE network that combines and concurrently supports all 3 types of network requirements Original goal of HPCC and NGI programs End to end (host-campus-LAN-MAN-WAN) Wavenet (L1), Framenet (L2), Packetnet L3) via same infrastructure The NLR is that network !

13 13 © 2004, Cisco Systems, Inc. All rights reserved. Aiken & Boroumand Summary To really make advances we need to go back to the ARPANET and early NSFNET concept where applications, middleware, security, network management, systems management, and network (layers 1-9) R&D coexist and compliment each other on the same infrastructure These were the goals of the HPCC and NGI programs We need campus, metro, state, regional and national research infrastructures to support this goal NLR is the only such National infrastructure so designed to support this challenge
