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

Transpacific network

Currently; n x STM4c network (Total capacity; 3.6G)

End of 2002; STM16c implementation (DWDM based)

Traffic Engineering

•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.

Implementation of MPLS-TE………….

- 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

Cache server

Load Balncers

Original Server

Copy / Split Contents / Streams

• 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.

• Improve end customer’s experience • Enhance server durability against surge of demands

• 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 Global IP Network is Multicast traffic enabled

- Multicast peering with other commercial/R+E networks are done at multiple major peering points worldwide

¶ 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)

Performance Monitoring - SLA

http://www.ntt.net/cgi-bin/showservice.cgi?LANG=enhttp://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.

Intra USA 60ms round-trip

•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!

Performance Monitoring - Plans

•End-to-end SLA:Demand for IP VPN users rising.Implement end-to-end SLA on the Gateway based IPVPN

•Site specific SLA:e.g. Seattle PoP to New York PoP
