Efficient collective communication in WDM networks with a power budget

This paper addresses the problem of efficient multicast communication in wavelength-division multiplexed optical networks. In particular, we consider all-optical networks in which each transmitting node may deliver its message to some fixed number of destination nodes on a light path. The number of destination nodes that may receive the message using a single path depends on the power budget of the transmitting node. We study the wavelength requirements for multicast communication under this model.
