A network slice managing entity, comprising means configured to obtain a service request for a network slice, the service request defining service requirements; request network slice descriptions from a database and selecting at least one network slice which support said service requirements according to the descriptions; generate a resource graph comprising nodes representing infrastructure resources and links representing connections between the nodes, the resource graph depicting resources needed for providing the service, wherein the generating is carried out based on a network slice description of the selected at least one network slice; transmit the resource graph to an infrastructure manager for mapping a topology of said network infrastructure onto said resource graph and determining at least one subset of said network infrastructure; and, receive a mapping result from said infrastructure manager containing said at least one subset of said network infrastructure.

A method for recovering transmission errors, comprising: receiving a data packet comprising an error detection code associated to data contained in the packet, wherein the data associated to the error detection code comprises primary data and secondary data, checking the error detection code of the received packet to detect an erroneous state of the associated data, when the erroneous state is detected, determining a finite set of candidate values for the primary data and, for each values of the set: determining a marginal likelihood of the candidate value as a function of the error detection code of the received packet, determining a first correlation between the primary data of the received packet and the candidate value, and selecting a corrected value for the primary data among the set of candidate values as a function of said marginal likelihoods and said first correlations.
