Photonic Packet Switching
IN THIS CHAPTER, we study optical networks that are capable of providing packet-switched service at the optical layer. We call these networks photonic packet-switched (PPS) networks. Packet-switched services are provided today using electronic switches by many networks, such as IP and Ethernet networks. Here, we are interested in networks where the packet-switching functions are performed optically. The goal of PPS networks is to provide the same services that electronic packet-switched networks provide, but at much higher speeds.
The optical networks that we have studied so far provide circuit-switched services. These networks provide lightpaths, which can be established and taken down as needed. In these ...
