A system comprising: - a provider module (110) configured to serve a Software Defined Infrastructure (SDI) service request generated by a consumer (105), such SDI service request being formulated in a first language; - an NSP translation module (140) configured to translate such SDI requests from said first language into a corresponding service chain comprising a set of Network and Service Primitives (NSP) comprising at least one NSP; - a service space module (150) configured to map each NSP of a service chain onto a multidimensional vector space by exploiting a space matrix, said space matrix being a data structure providing the positions within the multidimensional vector space of vectors NSP(i) corresponding to any possible NSP; and wherein - said service space module (150) is also configured to query said space matrix with a sequence SNSP of vectors NSP(i) so as to retrieve a further sequence SNSP' of vectors NSP'(i) by carrying out on the vectors NSP(i) of the sequence SNSP geometric operations in order to find a level of similarity between such vectors and the vectors of the V -dimensional service space SS so as to carry out at least one among: - predict a new NSP in the composition of the further sequence SNSP' starting from a set of neighbors NSPs composing the sequence SNSP ; and - predict a set of neighbors NSPs composing the further sequence SNSP' , starting from a NSP of the sequence SNSP .
