The increasingly fierce competition between information and communications technology (ICT) companies is increasing the need for them to carefully cultivate markets, by first starting small and then later expanding processing power so as not to affect existing services.Parallelizing services is an important technology in this process while multiplexing is an essential technology in building highly reliable systems.Furthermore, services are being added and modified with increasing frequency in order to handle diversifying customer needs in a timely manner, and the number of service users and smart devices, such as smartphones, is increasing rapidly.For these reasons, packet data traffic on IP networks is growing and diversifying more and more quickly.This paper describes network infrastructure technologies for creating scalable infrastructures that can appropriately distribute diverse and high-volume packet data to parallelized and multiplexed server systems providing highly reliable and high-volume services and that enable services to be added and modified frequently.It also discusses initiatives at Fujitsu in this area.
