Application of Server Virtualization Technology to Communication Services

Following the Great East Japan Earthquake of 2011, the volume of traffic on the mobile communications network spiked to about 50 to 60 times the normal busy-hour volume, thereby congesting the system and making it difficult to provide users with stable services. To provide stable services even during times of congestion caused by a disaster, Fujitsu is researching and developing the use of virtualization technology for flexibly and quickly allocating machine resources to communication services. This control technology is expected to improve the communication rate of priority services by decreasing the allocation of resources to services deemed low priority at the time of a disaster such as video and rich content delivery while increasing the allocation of resources to high-priority services such as voice calls and mail, which typically would be for obtaining disaster-related information and for checking on the wellbeing of people in the disaster area. This paper introduces Fujitsu's approach to establishing a server virtualization infrastructure for communication services.
