A New Routing Protocol for All Optical Network

Abstract: In this research paper, an efficient routing protocol for all optical network (AOL) is proposed. The technique uses wavelength division multiplexing (WDM). The proposed one is different from the conventional AOL protocol in transmission of data and control over optical fiber. A set of wavelengths is reserved to transfer control information, which is defined as control wavelengths. Control wavelengths are routed with packet routing scheme and the others are routed with wavelength routing scheme. In connection oriented network only the control packets are sent with the control wavelengths, data or messages are sent with other wavelengths. On the other hand, in datagram network, all the packets are sent with the control wavelengths. The allocation of wavelengths may be fully dynamic.
