Abstract :
We have addressed synchronisation of optical packet switched network on a mesh topology. The focus here is the synchronisation architecture for the optical packets in TWIN based network. The optical packets from different sources are passively groomed on one wavelength with a central control/management plane. In order to provide the necessary precise synchronisation system between the central control entity and all other nodes the synchronisation information time-stamp is carried on in band dedicated control channel throughout the network. In addition, the synchronization mechanism enables the network to operate in presence of realistic temperature variations of the fibre and include a correction of the effect of chromatics dispersion on the propagation delay calculation.
