KDDI, the second largest mobile operator in Japan, has selected mobile content delivery network (CDN) technology from Korean firm CDNetworks for integration into the core of its 3G and 4G networks.
The technology was selected after a lengthy series of tests which began in December 2011, and is expected to provide up to 30% faster mobile content delivery as well as up to 20% reduction in mobile data traffic.
It achieves this through a combination of text compression, which reduces mobile data traffic without changing content; video pacing, which reduces excessive progressive video downloading; and TCP acceleration, which is delicately tuned to fit the mobile operator’s network environment.
“KDDI is very excited to implement CDNetworks’ mobile CDN technology,” said Yoshiharu Shimatani, Senior Vice President and General Manager of Technology Sector at KDDI. “This will serve as a key technology for handling mobile traffic increase.”
