Abstract: A dynamic wavelength management in an optical burst switching system guarantees QoS by using wavelength resources effectively and using only a basic offset time for guaranteeing a specified blocking loss rate without incurring any additional delay. A control header packet and data having a plurality of wavelengths are fed to a core node asynchronously, and the control header packet is processed in a control plane, during which a wavelength group list is created corresponding to a number of classes and the respective group list is dynamically reconstructed corresponding to each QoS group.

Abstract: The biggest bottleneck in the Internet today is caused by the slow speed of routers, compared to the speeds that are achieved by optic fibers with DWDM (Dense Wave Division Multiplexing). Packet switching or something similar to it is needed not just for better utilization of the lines, but also because it is superior to circuit switching in many ways, such as better scalability as the Internet grows, better handling of traffic congestions, and better routing flexibility. But optical routers are currently unable to do packet switching except by translating the data to electronic data and then back, which is very inefficient.

Abstract: The invention relates to a method and a system for the transferring of packet-switched information in a telecommunication system which comprises a router (R) to which an optical cable (LC) is connected that consists of optical fibres (LF) to which two wavelengths of light are sent and which is connected to the telecommunication network (CN), in which method, at the router (R), the piece of address information is received from the address wavelength (AWL) of the optical fibre (LF); and the payload information is received at the router (R) from the payload wavelength (DWL) of the optical fibre (LF). In the method, the payload wavelength (DWL) is routed based on the received piece of address information.
