Effect of Splitting Factor on the Generated Multicast Trees in Optical Networks

Enhanced optical switches structure can now handle
multicast routing in the optical layer. For an optical node
to be able to do branching in the physical layer, it must
be equipped with a light splitter. Light splitters are
expensive equipment. A lot of work had been done in order
to reduce the cost of implementing splitters within the
network. Moreover, the internal structure of a splitter is
enhanced to reduce its cost, and the power loss resulted of
multiple splitting. Efficient placement of splitters in the
network leads to a reduction in the cost of the network
design, and the cost of the generated trees. The splitting
capability of each splitter plays an important role on how
much branching can be done on the optical node. Also, the
splitting capability affects the power loss done on each
branching node, and consequently the final power received
by each member. This paper studies the effect of the
splitting factor on the cost of the generated trees and the
value of the power received by each of the multicast group
members.
