Patent ID: 8305915

Claim:
A method or the digital evaluation of a data transmission network with a multiplicity of nodes ( 1 ) and of data transmission links ( 2 ) extending between the nodes ( 1 ), each node ( 1 ) including at least one input or output interface ( 11 , 12 ) with a multiplicity of queues, each queue being designed to receive data in the form of an analytical or event-based data stream, the data flow being divided between the queues as a function of classes of service associated with the stream, the method implemented using a digital computer programmed to perform the steps of: identifying interfaces with a hybrid operating mode, each receiving at least one event-based data stream and at least one analytical data stream, for each interface with a hybrid operating mode, determining, for the event-based data stream, a given class of service (k) received by the interface, a virtual equivalent queue associated with the given class of service (k), the virtual equivalent queue having an equivalent service speed (TRFE(k)), with a view to evaluating the data transmission network by associating, with the interface, the virtual equivalent queue receiving the event-based data stream with the given class of service (k), wherein the step for determining a virtual equivalent queue includes sub-steps of: converting the event-based data stream with a class of service (k) received by the interface into an equivalent analytical stream (λ ek ), and determining the equivalent service speed (TRFE(k)) as a function of a service law (Γ) governing the data flow received by the interface and taking account of the equivalent analytical data stream.
