NTT/VERIOs 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

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.

New Product Development Roadmap
Base products serve as a platform to enable more
advanced products/applications.
Video broadcasting over IP
Interactive Voice/Video over IP PF

  • IP Sec Gateway aggregates IP Sec tunnels from
    each end customer sites.
  • The Gateway governs the configuration of complex
    IPVPN (cost benefit and ease of management).
  • Combine with...
  • MPLS traffic engineering scheme to implement QoS.
  • CDN scheme to performance and server reliability
    enhancement

Content Distribution Network
Copy / Split Contents / Streams
Cache server
  • Improve end customers 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 lt-gt 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/RE
    networks are done at multiple major peering
    points worldwide

Performance Monitoring - SLA
Current SLA NTT/VERIOs IP backbone network
guarantees
Packet Loss
Latency
Trans - Atlantic
90ms round-trip
Intra USA
60ms round-trip

Trans - Pacific
130ms round-trip
300ms round-trip
Asia - Europe
http//www.ntt.net/cgi-bin/showservice.cgi?LANGen
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.

13
Performance Monitoring - Plans
  • Conforming with ITU quality standards
  • ITU-Ts 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

GEMnets 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/VERIOs 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
