RESUMO
When evolving from SDH/SONET synchronous network infrastructures, WDM networks tend to be initially configured in the same physical topology as their client networks: the ring. The fast growth of high-speed traffic volumes that characterize modern networks, however, is expected to drive the evolution of this topology. Growing the fiber plant by adding up more WDM rings is a possible evolutionary strategy for the optical network. This can be done while keeping the nodal degrees or not. With the addition of more fiber, rings can be just duplicated with the addition of more OADM s and possible permutation of the nodes, or else they can be connected through routing nodes (OXC s). The latter alternative allows for the implementation of chords on the ring, which are characterized by the number of hops subtended by each chord in the original ring. This work compares the capacity gains that can be obtained through such strategies.
