The invention relates to a method for generating, on the fly and on demand, at least one virtual network (), adapted for a specific use, on a physical network (), referred to as an infrastructure network, including physical nodes (), each of said physical nodes () runs at least one network operating system, said method including the following steps: determining, on at least one computer device (), referred to as a virtual network server, data related to said virtual network () to be generated in accordance with said particular use; transmitting, on the basis of said data and to at least a portion of said physical nodes (), referred to as active nodes, of said infrastructure network (), a request for creating a virtual node; and creating a virtual node on each of said active nodes by installing a virtual device in each of said active nodes, said virtual network consisting of all of said virtual nodes thus created. The invention also relates to a system implementing such a method.

Method and system for deploying at least one virtual network on the fly and on demand

A lattice of interconnected concepts is constructed from flow entries. Each concept describes a subset of flows and a subset of the flow attributes. Based on user queries, the lattice is used to build disjoint sets of flows referred to as flowsets. Each user query specifies one or more of the flow attributes to be measured. Each flowset includes one or more of the flows to thereby enable sharing of the hardware counters among the flows. One hardware counter is then assigned to each flowset.
