Novel Optical Network Architecture utilizing Optical Code Division Multiplexing Technology

光码分复用（OCDM）技术具有易于控制的特点，有望成为实现未来超高速网络的基础技术之一。目前对OCDM的研究大多集中在器件等底层技术上。OCDM具有IP友好性，因为它可以异步处理灵活长度的数据包。因此，在本研究中，我们有效地利用了OCDM的这些特性，提出了一种考虑应用层的新型网络架构。我们还考虑了有效复用各窄带和宽带应用的流量控制方法。我们通过理论分析和实际实验对所提出的架构和方法进行了评估，以证明其有效性。

Optical Code Division Multiplexing (OCDM) technology with easy controllability is expected to become one of fundamental technologies to realize future ultra-high-speed network. Most of current researches in OCDM are done on low-layer technology such as devices. OCDM has IP friendliness because it can treat flexible length packets asynchronously. So in this study we utilize such OCDM features effectively and we proposed novel network architecture considering application layer. We also consider traffic control methods which multiplex flows from each narrowband and broadband application efficiently. We evaluated proposed architecture and methods through theoretical analysis and actual experiments, so that we could show their effectiveness.
