Abstract: A method of providing a service to a requesting Infrastructure Element belonging to plurality of Infrastructure Elements interconnected as a data network is proposed. The method includes operating a computing system for receiving a service request requesting a service from the requesting Infrastructure Element. The service request includes an indication of one or more performance requirements. The method also includes converting the service request to a service graph, which includes at least one task to be accomplished by complying with the performance requirements to provide the service. At least one Infrastructure Element currently capable of accomplishing the task complying with the performance requirements is selected, and the selected Infrastructure Element for accomplishing the task is configured. The method further includes causing the selected Infrastructure Element to accomplish the task to provide the service to the requesting Infrastructure Element.

Abstract: It is disclosed a method and system for providing a service to a user. The system comprises a module (VAHI) associated with the user and configured to act on her/his behalf and a plurality of modules (VAE) associated with and representing respective physical resources. The system comprises a runtime distributed execution environment for running VAHI and VAEs, such environment being provided with a distributed operating system supporting access by VAHI and VAEs to the physical resources. The VAHI is capable of having an interaction with the VAEs and, as a result of such interaction, providing the user with a proposal for the provision of a service. Upon reception of an approval from the user, the VAHI is capable of instructing at least one of the VAEs to request the associated physical resource to perform an action providing at least part of the service according to the proposal.

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.
