Needed to solve heavy network traffic issues and reduce transit costs.

As the number of t-broad users was increasing, some sections of network were jammed by heavy network traffic; and this heavy traffic hindered T-broad service quality and reduced network reliability. In addition, it was not cost-effective to use t-broad’s existing transits since T-broad had to purchase transits and charge the cost to the customers as the number of t-braod users was increasing.

What did KINX do?

Suggested local peering to solve the main two issues.

The key strength of local peering is reducing transit costs by directly interconnecting peerg members and direct connection with 42G KINX backbone network enhances quality and speed of the Internet. After joining KINX local peering, t-broad provided more improved quality and high speed to its 17% of the eyeballss in Korea.

Improved quality and reduced costs at the same time with KINX local peering service

Local peering provided by KINX solved the main two issues that T-broad experienced: low speed due to heavy network traffic and expensive transit costs. Peering can be very cost-effective compared to using transits. While peering over an Internet eXchange(IX) just requires a connection to the IX, setting a transit requires a connection from an end to another end. Plus the cost of a transit itself is more expensive than peering.
All in all, t-broad reduced transit costs by using local peering over an IX and enhanced its Internet service.
