Provided is a management-system for use in a network environment including a first and second IP networks and a transport network which connects the first and second IP networks. The management system includes: a converter for optimizing a path in an IP-domain via a first algorithm and for converting IP-traffic-signals into transport-traffic-signals; and an optimiser which optimizes a topology that overlays the transport network by optimizing channels in the transport-network according to at least one second algorithm. The first algorithm is an IP multi protocol label switching routing optimization algorithm. The second algorithm is an algorithm based on a plurality of constraints and objectives such as a flow conservation constraint, logical link capacity constraint, optical router port constraint, wavelength cost objective, optical router port occupation objective, advertised link number objective, spare capacity objective, wavelength re-use benefit objective and optical service level agreement constraint.

Network-system, management-system, method and computer program product

A device for emitting radiation at a predetermined wavelength is disclosed. The device has a cavity comprising a first bulk region and a second bulk region of opposite conductivity type wherein a barrier is provided for spatially separating the charge carriers of the first and the second region substantially at the antinode of the standing wave pattern of said cavity. The recombination of the charge carriers at the barrier create radiation, the emission wavelength of the radiation being determined by the cavity.
