Abstract

With the emergence of optical cross-connects (OXCs) and optical add/drop multiplexers (OADMs), all-optical networks and a new layer named as optical layer are emerging. Although the number of available wavelength per fiber and the bandwidth per wavelength are all becoming larger, the total bandwidth per fiber is limited. So for a network operator, pre-allocating minimum spare capacity in an optical network under the advanced connection demands to meet to survivability requirements is needed. In this paper, the above problem can be formulized as an ILP model, in which different survivability requirements of connections are considered jointly. The solution to this problem has an advantage over the result of the separate allocation problem, i.e., allocating resources for service connections and protection! restoration connections are performed separately.
