In this paper, we investigate both static and dynamic traffic grooming problems in a wavelength routing network, so as to minimize the total energy consumption of the core network, with the additional consideration of the holding times of the lightpaths and connection requests. In static case, all connection requests with their setup and tear-down times are known in advance, we formulate an Integer...
In this paper, we propose a novel polarization-assisted scheme for flexible multicast overlay in a WDM-PON, which supports both point-to-point (P2P) downstream and upstream data delivery. With our proposed wavelength assignment and routing schemes, the system performance is greatly improved. No additional dedicated light source for the multicast data is needed. We have experimentally demonstrated...
An optical prime-number-encoded tag is employed as distinct network node identifier so as to realize network node tracing in reconfigurable wavelength routing networks, via prime number multiplication. Possible network looping problem can also be identified.
We propose a novel optical packet time-to-live (TTL) processing scheme using periodically phase-modulated TTL fields. Asynchronous packet TTL countdown and eventual dropping of expired packet using this scheme was experimentally demonstrated.
