heal.abstract	Bit-asynchronous optical packet-switched networks are seen as viable candidates for Metropolitan areas. For such networks we are proposing labeling of the optical packets based on multidimensional headers constructed by using a combination of two or more physical properties like time, wavelength, sub-carried frequency, or polarization state. The resulting header can be processed using slower electronics than the line rate without any sacrifice of the information transfer rate and with higher immunity with respect to degradation of the optical signal-to-noise ratio (OSNR). Packet identification as well as header-payload separation is achieved using passive devices. This method for constructing and switching information as well as transporting frames offers potential speed processing gains over the binary case as well as improvements on bit-error rate versus OSNR. The feasibility of using headers constructed by combination of wavelength and in terms of dispersion and spectral efficiency is established as a function of bit-rate and distance. Finally a generic architecture for a suitable optical packet add/drop node is described.	en
