1 Private Industry Role in Next Generation Internet Bob Aiken NGI Project Leader DOE er.doe..doe.gov Large Scale Networking Working Group June 1997
2 NGI: Foundation for the Future
3 Points to Remember Dynamic Virtual Networks are the Future Joint Industry, Government, and Academic R&D collaborations are essential for success
4 Goal 3 : Applications Applications Medicine Crises Management Basic Sciences Education Environment Manufacturing Federal Services Characteristics Distributed Computing Remote Operation Digital Libraries Collaboratories Privacy / Security
5 Goal 2 : Technologies Network Engineering Planning and Simulation network planning language run time tools Monitoring gathering data network engineering network management run time (i.e. dynamic) analysis QOS and drill down analysis tools Integration engineering tools, switching/routing, and transmission to work smoothly
6 Goal 2 : Technologies ctd. Network Engineering ctd. Data Delivery routing / switching best effort vs priority traffic dynamic routing vs virtual circuits (VCs) greedy admission vs guaranteed delivery flat rate vs variable costing multicast (reliable vs unreliable) real time protocols and traffic
7 Goal 2 : Technologies ctd. Network Engineering ctd. Managing Lead User Infrastructure (fast, complex, dynamic) Concurrent Production and Network Research traffic (virtual networks) (de) aggregation of tributaries operation and management strategies and tools scaling ( speed, size, complexity ) user requirements that are orders of magnitude larger and more complex that normal applications and traffic
8 Goal 2 : QOS (end-to-end) Baseline QOS Architecture framework of models, languages and protocols to specify QOS negotiate acceptable tradeoffs receive feedback on delivered QOS (enable adaptation) APIs supporting propagation of QOS constraints and feedback admission control accounting / costing prioritization Drill Down Technologies support QOS across ( drill down ) layers expose interfaces to QOS and network capabilities emphasis on OS< communication libraries, middleware services and distributed objects
9 Goal 2 : QOS (end-to-end) ctd Next Generation Network Technologies (in addition to QOS) RSVP IPv6 Routing / Switching Multicast ( IP and ATM ) Real Time protocols admission control ( IP and ATM ) accounting / costing ( IP and ATM ) scheduling ( IP and ATM ) prioritization ( IP and ATM )
10 Goal 2 : Security secure and fair means for users to access network resources (e.g. QOS) smart network management inter-network peering (e.g. surety of routing updates) nomadic/remote access Public Key Infrastructure (industry interoperable)
11 Goal 1 : 10 sites at 1000x end-to-end gigabits and terabits to Applications end system 1000x interfaces (e.g. HIPPI 64) Operating System (OS) and end system architectures 1000x network management tools / capabilities (de) aggregation of high speed tributaries WDM at WAN, LAN and Local Loop optical, electrical, hybrid hardware interconnect to 100x networks
12 Goal 1 : 100 sites at 100x end-to-end 100 megabits and up 100+ Universities, Labs, and Federal Centers supports applications (goal 3) using advanced network technologies (goal 2) IPv4 minimum bearer service IPv6 in future ATM and other services as required (VPNs) Gigapops (aggregation points) vbns is I2 and Gigapop interconnect fabric concurrent production and network research
13 Prod APP MORPHNET(Virtual Networks) R&D APP (RSVP) R&D APP Prod IP R&D IP (IPv6) R&D APP PROD ATM R&D ATM SONET or WDM Multiplexing
14 Goal 1:100 sites at 100x ctd Interconnection at L2 and L3 among Federal Networks / Carriers QOS ( IP and ATM) Management tools and capabilities ( NOCs, Helpdesks,...) Monitoring, Analysis and Accounting (settlements) tools routing / peering exchanges between Federal networks and Federal networks at Gigapops (when appropriate) Flexible and dynamic methods for setting up interagency virtual networks
15 Goal 1 : 100 sites at 100x ctd Network Management distributed help desk security and authentication methods gigapop and agency network NOCs ( NOC to NOC ) applications can schedule bandwidth and services network management tools ( existing and new)
16 Summary Need joint commercial, government, and university R&D ventures to define and build the future Network and services End users need capabilities to see and control the Network The Network is : switches, routers, muxes lines, circuits, services end systems, operating systems, libraries applications people, relationships
