TOKYO -- NTT Communications (NTT Com) announced today that it will offer a high-standard 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:

Region -- Max. latency
Japan -- 25 ms
U.S. -- 60 ms
U.S.-Europe -- 90 ms
Japan-U.S -- 130 ms

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.
