Design concept for future carrier networks

The first challenge of a network is to achieve service flexibility that can adaptively provide a wide range of network services to each customer. Future networks will need to satisfy a widely expanded scale of customers' demands. Various service parameters will need to be scaled up to accommodate the wide variety of network applications required by each customer. Typical parameter examples are the so-called network QoS, which includes factors such as bandwidth, transmission delay, and jitter. In addition, the number of terminal equipment devices involved should be considered. In the business field, a wide variety of network-based applications and services have been adopted. Since leakage of confidential information is a critical issue for companies, thin client style computations are widely recognized as a secure implementation for business usage. SaaS (Software as a Service) and PaaS (Platform as a Service) type applications are recognized as cost effective solutions. In recent years, low cost wireless networking techniques have been widely and rapidly spreading. Passive type RFID is expected to achieve efficient management of manufactured goods. Even in the managing of paper documents, very small IC chips are expected to play important roles. Active type RFID systems are another category of low cost wireless networking techniques.
