NTT Communications will launch a service-level agreement (SLA) guaranteeing 100% network availability, as well as latency and packet loss levels, to customers using IPv6 services provided on NTT Com’s global Tier 1* IP backbone network beginning July 1.
If the services do not achieve the quality levels guaranteed under the SLA, NTT Com will refund all, or a pro-rated amount, of the customer’s service fee.
The maximum average time for round-trip packet communication (maximum latency) in a given month is guaranteed in each of four regions is as follows. Packet loss is guaranteed to be less than 0.3% on a calendar month basis in all four regions.
SLAs will be offered for the following three existing services:
- Option service of Transit Service, IPv6/IPv4 Dual Service (provides both IPv6 and IPv4 connectivity to Tier 1 IP backbone using only one access circuit)
- Option service of Collocation Transit Service, IPv6/IPv4 Dual Service (provides data center customers with IPv6 and IPv4 connectivity to Tier 1 IP backbone)
- IPv6 Native Service (provides IPv6 connectivity to Tier 1 IP backbone)
Going forward, NTT Com expects to offer SLA guarantees in other major regions of the world.
NTT Com launched the world’s first commercial IPv6 connectivity service in 2001.
