The network has a major role to play in improving future information communications and technology systems (ICT) and then society. Let’s take for example Cloud Computing, which is a major trend today in the ICT world. Cloud computing is based on the existence of broadband networks. Today more and more technology providers are offering Cloud services due largely to the demand for services/resources on demand brought about by widespread broadband access.
A variety of web services have been created and people are enjoying them via the network. As this trend accelerates, telecommunication networks are becoming increasingly important as social infrastructures. This engenders the need for capacity growth with cost reductions, greater flexibility, network virtualization and visualization, more use of wireless and provision of new experiences via the network.
Capacity growth with a lower cost per bit is a continuous requirement in telecommunications, and new technologies have been developed to meet this demand. These days, new technology trends can be seen in both optical and wireless communications. Network flexibility is also a continuous demand. At present, the packet-switched network provides flexibility, which especially suits the current Internet. However, the majority of network traffic is gradually moving towards video streams, TV broadcasts etc. To enable the network to efficiently accommodate these types of traffic, we need a different level of flexibility involving converged networks.
Virtualization is one of the key ways for ICT systems to provide cost efficiency for resource sharing and easy service deployment. Networks are also moving in this direction. As the basis of virtualization, network visualization is an essential technology,. It is strongly desired even for current networks because it is difficult to grasp the total network configuration and operating status of the Internet. Wireless communication is also expanding its field of applications because of the freedom of mobility it provides.
From the business point of view, new network service offerings that give the customer new experiences are essential. At present, the potential capabilities of networks, such as connecting to anything, reaching everywhere, and gathering huge amount of data, are not utilized well enough to provide services for users. A network service platform for efficient network services provisioning and easy service creation is strongly needed.
Today, as well, most technology companies are taking into account environmental impacts. Smart usage of networks can contribute to efforts to solve the problem of global warming by eliminating a lot of transportation, reducing the amount of hardware produced by efficient sharing of resources (as in Cloud computing), avoiding unnecessary use of electricity through monitoring and control, and so on. Making networks themselves green is important.
