  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.

• 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

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

Implemented SLA measurement probes at every PoP.
The central server aggregate the data from each
probe to ensure the SLA value.

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
