“…Recently, the multicast traffic grooming problem (grooming of multicast requests over light-trees) has begun to attract research attention [18]- [12] and [13]. All these articles studied the multicast traffic grooming problem based on the lightpath model and approached the problem using integer linear programming (ILP) and heuristics.…”

Optical channels are currently able to carry 10 Gbit/s and even 40 Gbit/s traffic flows. However, it is not usual to have such amounts of traffic between any pair of client nodes. This article proposes using point-tomultipoint optical channels for the allocation of pointto-point connections in transparent wavelength-routed optical networks. Specifically, when an optical connection between a source-destination node pair has to be established, the optical signal is also sent to some adjacent nodes by introducing passive optical splitters; in this way a light-tree is built. Then, the already established point-to-multipoint optical channel can be used to groom further point-to-point connections between the same source node and each of the other nodes composing the light-tree. The benefits of this strategy are 2-fold: first, the reduction of optical transmission equipments allowing cost savings with respect to the traditional typical point-to-point approach and, second, the optimization of the optical channels utilization meeting in such a way Traffic Engineering objectives. The merits of proposed approach are evaluated by simulation.

“…In this context, optical transparency is largely confined within each basic topology. The wavelength division multiplexing (WDM) of optical signals is a promising way to increase the transmission capacity of a fiber [3]. In WDM systems, a wavelength multiplexer and demultiplexer based on an arrayed waveguide grating (AWG) is an essential component in order to multiplex and demultiplex the light signals.…”

“…AVELENGTH conversion has been suggested as a method of enhancing routing options and network properties like reconfigurability, nonblocking capability and wavelength reuse [1], [2]. Cross-gain modulation (XGM) [3], [4], cross-phase modulation (XPM) [5], [6], and four-wave mixing (FWM) [7]- [9] in semiconductor optical amplifiers (SOA's) have been demonstrated for 40 Gb/s wavelength conversion.…”
