Key Technologies Of Wavelength Routing Optical Packet Switching

Compared with the traditional optical networks, Optical Packet Switching (OPS) network has many highlight advantages including high-speed, high-throughput, low latency, high efficiency for IP service carrying and so on. In early 1990, a few foreign countries have started the research on optical packet switching technology, early research mainly focused on the key components. So far, many developed countries in the world have conducted research on optical packet switching networks and established their own optical switching experimental systems, and have made great progress. Not only there was a breakthrough of the structural design of switching, such as the proposing and verification of a variety of switching matrix, competitive solutions, optical signal processing method, but also there were achievements on realization of the switching system. For example, the optical packet switching experiment has been completed in a small environment, core router with the optical packet switching functionality can achieve space division switching, time division switching and wavelength division switching meanwhile. And the core router only processed with high-speed on the optical packet header with routing information, while providing a transparent path for the optical packet payload. All these progress has provided the foundation for the realization of optical packet switching networks.In our country, the research on optical packet switching technology has just started in recent years. Most of them tracked the development of the foreign research, focused on the research of the single components and only a relatively low switching rate has been achieved. Therefore, carrying on research on optical packet switching-related technology is significant.In this thesis, the main study is in the wavelength-routed optical packet switching and its key technologies. Through modeling and simulation of transmission control protocol (TCP) performance in the optical burst switching network, a reference model for the study of the transmission performance of TCP in the wavelength-routed optical packet switching networks is provided. Chapter 1 introduces the development of the optical switching network technology and research situation. Chapter 2 mainly discusses the generation of the optical packet switching technology and related key technologies, including extraction and insertion of the optical label, optical packet synchronization, optical packet switching, competing solutions of optical packet, optical packet regeneration and so on. Chapter 3 mainly discusses node technologies of the optical packet switching, including the composition of optical packet switching networks, node structure of optical wavelength switching, types of packet switching node structure, etc. Chapter 4 mainly discusses the structure of TCP over OBS in wavelength routing optical packet switching networks, and models and simulates transmission control protocol (TCP) performance in the optical burst switching network, which aims to offer a reference for TCP transmission performance in wavelength routing optical packet switching network. Chapter 5 summarizes the major works of this thesis and prospects the future research.
