Internet Gateway

High-capacity and high-quality global IP transit services.

Features

High-capacity backbone

Wide-area, low-latency internet connection has been achieved using KDDI's high-capacity global backbone. KDDI has built backbones in the US, Hong Kong and Singapore, enabling a direct, high-capacity connection with these countries. The covered area will gradually be expanded.

High-capacity backbone

Enhanced network management system

KDDI's Network Operation Center monitors SLA (Service Level Agreement), BGP (Border Gateway Protocol) sessions and traffic troubles 24 hours a day, 365 days a year. In addition, it carries out constant monitoring of network traffic and performs scheduled network upgrades to maintain high performance.In the event of a failure, staff at the center move swiftly to verify the situation, contact the customer by fax or email and implement the necessary recovery steps. The center also handles customer inquiries 24 hours a day.

IPv4/IPv6 support

Users can select IPv4, IPv6 or IPv4 + IPv6 on one circuit according to their usage status. KDDI provides the following routings to meet users' needs.

  • IPv4: BGP (Global AS) full transit / Static
  • IPv6: BGP (Global AS) full transit / Static

Functions

Visibility

It is possible to identify the traffic volume, number of sessions and traffic volume per session for each application in real-time and by the historical data. Over 90 applications can be identified automatically by default registration in the software and users also can set their own additionally registered applications.

Optimization

The traffic flow of the entire network is optimized based on the target values defined for each application on the optimization devices installed in each office and the central server that controls them. Applications can be assigned one of 15 user classes [1] that set the target values. User class priority levels beyond 15 are available as an optional service for an additional fee.

Acceleration

In addition to increased speed through a reduced number of ACKs [2] and expanded window size [3], efficient data transmission is realized through data compression and the cache function [4].

Dynamic WAN Selection (DWS)

In addition to "Visibility", "Control & QoS" and "WAN Acceleration", "Dynamic WAN Selection (DWS)" is provided as a new option service. DWS checks the quality of redundant networks automatically, and selects the best network for each application. Basically, higher-priority traffic uses a primary network, and lower-priority traffic uses a secondary network. However, they are flexible enough to use a better network when hangs occur, or quality and throughput get lower.

Reporting

This function provides a precise statistical report based on measurements at the packet level for all applications.

Virtual sites

With this function, users can ascertain application use without installing any equipment and utilize some of the optimization functions.

  • [1] A user class is one or more applications that have been grouped together. Multiple applications can be set for one user class.
  • [2] In computer communications, acknowledgement (ACK) is a signal sent from the destination computer in situations such as when data has been properly forwarded from the destination computer to the source computer.
  • [3] Volume of data that can be transmitted continuously without delivery confirmation.
  • [4] A function that stores frequently used data in a high-speed storage device in order to eliminate the need to read the data from a slow-speed storage device every time it is needed.

Service Level Agreement (SLA)

KDDI has set a SLA for the following four items and guarantees service quality by establishing a guarantee standard for each.

  • Availability
  • Latency
  • Customer Notification
  • Packet Loss

If the service quality fails to meet the standard, a portion of usage charges will be adjusted accordingly.
The SLA applies to all KDDI Internet Gateway users. No additional application or charge is required.
KDDI will continue to strengthen its SLA and further enhance service quality.
