Abstract: A system includes a provider module to serve a Software Defined Infrastructure (SDI) service request in a first language. The system includes an NSP translation module to translate the SDI requests from the first language into a service chain including a set of Network and Service Primitives (NSP), and a service space module to map each NSP onto a multidimensional vector space using a matrix. The matrix provides positions within the multidimensional vector space of vectors corresponding to any possible NSP. The service space module queries the matrix with a sequence of vectors to retrieve a further sequence of vectors by geometric operations to find a level of similarity between the vectors and the vectors of the service space, in order to predict a new NSP according to the further sequence starting from neighbor NSPs, and predict the neighbors NSPs composing the further sequence.

Abstract: An optical network is configured so as to dedicate a first portion of lightpaths to high priority traffic and leave a second portion of lightpaths available for low priority traffic. The high priority traffic entering the high priority lightpaths is monitored. In case of detection of a burst in high priority traffic, at least one of the low priority lightpaths is torn down, so as to make available network resources within the network. Then, a new temporary lightpath is set up using the available network resources, and high priority traffic is routed on the temporary lightpath.
