To exploit the unprecedented opportunities offered by the E-Service Applications, businesses and users alike would need a highly-available, reliable, and efficient telecommunication infrastructure. This chapter provides an insight into building the next-generation network infrastructure, that is, the All-Optical Internet. It also reveals the factors driving the convergence of the Internet Protocol (IP) and the Wavelength-Division Multiplexing (WDM) technology. The chapter discusses the dominant optical networks architectures in an attempt to show the evolution towards the ultimate all-optical packet-switching network. A special focus is given to the Optical Burst Switching (OBS) as a new emerging switching paradigm and a highly promising technology. OBS network architecture, burst assembly, signaling and reservation protocols, QoS support, and contention resolution techniques are presented. Furthermore, realistic suggestions and strategies to efficiently deploy OBS are given.

Optoelectronic hybrid network technology is mixed with pure electric packet switching network, which can improve network capacity and reduce power consumption. However, the long configuration time and complex management of optical circuit switch affect the performance of optoelectronic hybrid network. Therefore, a new optoelectronic hybrid network architecture (BET) is designed. The network architecture consists of Ethernet electric packet switching network and optical wavelength routing network. The signal receiving and dispatching of optical routing network is realized by circular arrayed waveguide grating router. Based on the characteristics of wavelength cycling routing, there is no need to adjust the routing of optical signals to the destination port, that is, there is no need to configure the optical wavelength routing network. At the same time, an intelligent node dynamic reconfiguration (RG) algorithm is designed to improve the resource utilization of optical nodes. In this method, the network link utilization, cache occupancy, and network load are taken into account to adjust the distribution of optical nodes in the optoelectronic hybrid network. In the process of the experiment, by changing the message length, it is found that the optical wavelength routing network can achieve large capacity and new-type transmission and effectively reduce the delay at the same time; on the optoelectronic hybrid network, with the help of Hadoop platform, distributed cluster is built and used to transmit an XML data encoding (ED code), solve the finite state transducers (FST) and encode them. Compared with the traditional electric packet switching network, the transmission delay of ED code is greatly reduced after the introduction of optical circuit switch, and the efficiency of FST solution and coding calculation is improved by at least 30%.
