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

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

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

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

To achieve finer granularity control of network flows 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.

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 GPRS(GRX) Wireless Access PF And more 2002-2004 Secure, reliable service platform Content Distribution Network NW base Security QOS, Multicasting IP VPN IP v6 2001- 2002 High performance Global IP Network Note: GRX: GPRS Roaming eXchange GPRS: General Packet Radio Service (Mobile IP network) IP VPN: IP Virtual Private Network

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)

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

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 Asia - Europe 300ms round-trip 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

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

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 MREN STAR TAP Japan 33 Mbps 6.5 M * Abilene 6.5 M 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 * Malaysia facilities (NTT MSC) NTT Musashino R&D Center * Otemachi Facilities * 35 Mbps * NTT Yokosuka R&D Center To the USA * NTT Keihan-na R&D Center * GEMnet connection point To Malaysia

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
