Global IP Network SLA

While everyone claims reliability, NTT Communications puts it in writing and displays the service metrics for you to view. It's our part of the most aggressive Service Level Agreements (SLA) in the industry. These SLAs provide certain rights and remedies regarding the availability and performance of the NTT Com Global IP Network.

We guarantee:

  • The NTT Com Global IP Network is free of Network Outages 100% of the time.
  • Latency will not exceed 50 milliseconds for the North American Network, 90 milliseconds for the Trans-Atlantic Network and 130 milliseconds or less for the Trans-Pacific Network.
  • Packet Loss will not exceed 0.1%.
  • Average jitter will not exceed 250 microseconds and will not exceed 10 milliseconds more than 0.1% of the time.

As described below, NTT Communications' Backbone Network Service Level Agreements (SLAs) provide commitments based upon goals in specific areas. Click on the following links to view current performance measurements with respect to the NTT Communications Backbone SLAs:
