  1. NTT/VERIO Global IP Network Plan Kazuhiro Gomi Global IP business department NTT Communications k.gomi@ntt.com

  2. NTT/VERIO’s Global IP Network • Global Single AS network to cover North America, Asia and Europe • US-Japan bandwidth; 3.6G • Backbone PoP location in Asia; Tokyo, Osaka, Taipei, Hong Kong, Seoul, and Singapore • Global SLA guarantees performance • Availability • Packet loss • Latency

  3. Network enhancement plan overview • Customer satisfaction enhancement • SLA, support systems, …. • New Service development • Adding intelligence, security, ... • Underlying infrastructure fortification • More bandwidth • Traffic Engineering Enlarging geographical coverage NTT/VERIO’s Global IP Network

  4. Fortification of underlying infrastructure Currently; n x OC48c network (DWDM based) Q1 2002; Start deployment of OC768c ready routers 2003-2004; Network will be ready for OC768c when long haul availability of OC768c is materialized. US network Currently; n x STM4c network (Total capacity; 3.6G) End of 2002; STM16c implementation (DWDM based) Transpacific network

  5. Traffic Engineering Implementation of MPLS-TE…………. • To achieve finer granularity control of network flows • To engineer faster and less service affecting failure restoration • To achieve more deterministic protection paths to preserve the desired packet loss and latency characteristics of the network.

  6. New Product Development Roadmap Base products serve as a platform to enable more advanced products/applications. Interactive Voice/Video over IP PF Video broadcasting over IP And more GPRS(GRX) Wireless Access PF 2002-2004 Secure, reliable service platform Content Distribution Network QOS, Multicasting NW base Security IP v6 IP VPN 2001- 2002 High performanceGlobal IP Network • Note: • GRX: GPRS Roaming eXchange • GPRS: General Packet Radio Service (Mobile IP network) • IP VPN: IP Virtual Private Network

  10. Content Distribution Network Copy / Split Contents / Streams Cache server • Improve end customer’s experience • Enhance server durability against surge of demands Load Balncers Original Server • Content distribution mechanism to be embedded in the backbone network as an utility service for end customers. • Improvement of connectivity between networks. Diversity of cache deployment for static contents is not the main requirements. • However, large streaming contents still needs to be distributed from the network edge. • Additional functionality on the cache (e.g. Subscription management at cache level, Content peering, etc) • Quality assurance mechanism (for Streaming contents)

  11. Multicast Network • NTT/VERIO's early adopter nature of native multicast: actively involved in mbgp and msdp spec finalization. • NTT/VERIO's community service role in kick starting native multicast deployment: NTT/VERIO has been providing PAIX side infrastructure for AS10888 (DVMRP <-> native multicast gateway service) • SSM (single source multicast) trials • Experience: provided native multicast transit services for 1999 Eugene NANOG and 2000 San Diego IETF • Actual customers’ usage of the multicast infrastructure (e.g. Real Networks) • NTT/VERIO Global IP Network is Multicast traffic enabled • Multicast peering with other commercial/R+E networks are done at multiple major peering points worldwide

  12. Performance Monitoring - SLA Current SLA NTT/VERIO’s IP backbone network guarantees Packet Loss Latency Trans - Atlantic 90ms round-trip Intra USA 60ms round-trip 0.3% Trans - Pacific 130ms round-trip 300ms round-trip Asia - Europe http://www.ntt.net/cgi-bin/showservice.cgi?LANG=en http://www.verio.com/sla Implemented SLA measurement probes at every PoP. The central server aggregate the data from each probe to ensure the SLA value. NTT/Verio Global IP Network

  13. Performance Monitoring - Plans • Conforming with ITU quality standards: • ITU-T’s SG13 working group is working on IP QoS which covers Packet loss, Round trip latency, and latency jitter. • ITU-T Recommendation Y.1541 – • Network performance objectives for IP-based services • ** To be finalized and made public real soon! • Site specific SLA: • e.g. Seattle PoP to New York PoP • End-to-end SLA: • Demand for IP VPN users rising. • Implement end-to-end SLA on the Gateway based IPVPN

  14. NTT’s R+E Network - GEMnet • NTT’s GEMnet • Activities of NTT R&D • R+E Network for non- commercial experiments • Member of UCAID for experiments on Abilene CA*net II STAR TAP MREN Japan 6.5 M 33 Mbps 6.5 M * Abilene San Jose facilities • Connected with: • Abilene • MREN • CALREN2 • CA*net II • JGN (Japan Gigabit • Network) • Also to South America • Via REUNA & AMPATH • To Chile 1.5 Mbps Japan * NTT Musashino R&D Center Malaysia facilities (NTT MSC) * Otemachi Facilities * 35 Mbps * NTT Yokosuka R&D Center To the USA * * GEMnet connection point NTT Keihan-na R&D Center To Malaysia

  15. GEMnet’s Experiments • Experiments on GEMnet include • Joint experiments on remote lectures with Kyoto Univ. and UCLA • Experiments on virtual space sharing network with Tokyo Univ. and University of Ilinois • Using QoS operation technologies – diffserv • * The above two links are strictly dedicated to the experiments. • Ipv6 operation experiments • Resulted in NTT/VERIO’s IPv6 platform • Experiments on advanced information delivery service – Mdome • Multicast experiments • Experiments on video conferencing • Data over photonic network (DoPN) • bandwidth controller over 1Gbps • Joint experiments with University of Chile • Future Plans on Experiments on GEMnet • Further joint researches with Universities in and outside NA • Experiments to further improve the efficiency of IP Networks
