Xh. Jia et al., Integrated algorithms for delay bounded multicast routing and wavelength assignment in all optical networks, COMPUT COMM, 24(14), 2001, pp. 1390-1399
There are two steps to set-up a multicast connection in all optical wavelen
gth division multiplexing (WDM) networks: routing and wavelength assignment
. Multicast routing is to find a tree in the network rooted from a source n
ode and connecting all destination nodes. Wavelength assignment is to assig
n a wavelength to the generated routing tree in such a way that if two tree
s share a common link, then they must be assigned with two different wavele
ngths. This paper proposes two integrated algorithms to integrate routing a
nd wavelength assignment. The proposed algorithms have the following advant
ages: (1) the number of wavelengths used is small; (2) the network cost of
routing trees is low; and (3) the transmission delay from the source to any
multicast destination is bounded. (C) 2001 Elsevier Science B.V. All right
