MF Starts Providing JPNAP Osaka "PI/CUG Service"

TOKYO, JAPAN - INTERNET MULTIFEED CO. ("MF"; Head Office: Chiyoda-ku, Tokyo; President and CEO: Koichi Suzuki) announced today that it is starting full JPNAP Osaka PI/CUG Service on June 1, with the cooperation of NTT SMARTCONNECT CORPORATION ("NTTSMC"; Head Office: Kita-ku, Osaka; President: Mitsuyoshi Okamoto). [1]

MF has been providing JPNAP Osaka PI/CUG Service on a trial basis since March 2007. The PI (Private Interconnect) / CUG (Closed Users Group) Service is a service capable for realizing redundancy with the existing JPNAP Osaka distributed Internet exchange (IX) service. The PI/CUG Service utilizes VLAN (Virtual LAN) [2] technology to enable secure, private traffic exchange between two or more designated members in a logical space that is virtually separated from the existing public JPNAP Osaka Service, and meets the diverse needs for customers of the JPNAP Osaka Service.

MF has also provided the full-scale "PI/CUG Service" as the JPNAP additional service since October 2006 in Tokyo.
