Needs for various multimedia applications requiring highly qualified services have been increasing and generating huge amount of Internet traffic. In order to support this trend, it is essential to develop an efficient and intelligent networking technology. Optical internet is a networking technology enabling to switch and transport optical packet-level data traffic beyond simple point-to-point transmission. It makes possible provide huge amount of traffic bandwidth and statistical multiplexing in optical signal level. These advantageous features of optical internet can provide highly qualified applications services to various customers and enable flexible and efficient network operation and management.
In order to build cost-effective optical internet, it is essential to study a guideline for optical system design which can achieve the target performance and to utilize the deployed systems to guarantee its initial performance under various network environment. For this purpose, we study a design framework and dimensioning issues for optical packet router, as a key networking element, in optical internet. This dissertation first introduces next generation optical internet architecture and requirements for the network. Design and dimensioning issues for optical packet router are also presented for economical optical internet system development. Network performance control mechanism is presented to maintain the initially designed target performance under dynamically changing traffic condition. This dissertation mainly studies the following three topics: node dimensioning, FDL-based optical buffer dimensioning, and shared wavelength converter pool. First, we study node dimensioning including burst assembly process and link dimensioning. In order to suitably operate burst assembly process, a decision mechanism of burst assembly parameters is proposed to suggest their lowest boundary values for achieving the target performance. By taking blocking performance at...
