Abstract:
A data packet transmission network comprises a stream of packets of data sent by a first terminal passes in transit through at least one network equipment with which there is associated a stream measurement unit; wherein the first terminal and the measurement unit are connected to a collection unit. The measurement method comprising the following steps: the first terminal sends a specific stream of packets, each having a different determined size, the sizes being such that in a set of r packets, r being a positive integer less than or equal to the number of packets of the stream, there are not any two subsets of the set of r packets comprising the same number of packets and having the same cumulative total size; the measurement unit analyzes at least one packet and at most r packets of the stream passing in transit through the network equipment.
Abstract:
In a data packet transmission network a stream of packets of data sent by a first terminal passes in transit through at least one network equipment with which there is associated a stream measurement unit; wherein said first terminal and said measurement unit are connected to a collection unit. The measurement method comprises the following steps the first terminal generates a stream of packets, comprising a first and a second session status control packets the measurement unit analyzes said first and/or second packet of said stream, in transit through the network equipment the first terminal sends the collection unit a sent packet stream description comprising at least the number of packets sent the stream measurement unit sends the collection unit a stream description comprising at least one information item indicating the number of analyzed packets; and the collection unit identifies each analyzed packet of the stream as a function of the stream description to correlate said stream description and said sent packet stream description packet by packet.
Abstract:
A method for collection of flow descriptions for flows relating to at least one client network, the client network being attached to an interconnection network. The method receives flow descriptions for flows coming from the client network, aggregates the flow descriptions for the flows coming from the client network as a function of an aggregation criterion, transmits the aggregated flow descriptions to a collection device, analyzes the flow descriptions for the flows coming from the client network to determine at least one flow characteristic specific to the client network, receives flow descriptions for flows coming from the interconnection network, filters the flow descriptions for the flows coming from the interconnection network, in which the flow descriptions for flows lacking the at least one determined flow characteristic specific to the client network are eliminated, and transmits the filtered flow descriptions to the collection equipment.
Abstract:
A method is provided for supervising a plurality of units in a communications network. The method includes a step of a first supervisor device receiving from a plurality of units information notifications having a plurality of information fields. For each information notification received, at least one imprint is generated, which includes codes extracted from predetermined fields of the notification. The method further includes counting the number of occurrences of at least one imprint, and notifying at least one master supervisor device of at least one imprint and the number of occurrences counted for that imprint.
Abstract:
In order to minimize a bandwidth required for the transfers of communication network administration information, said information relating to objects pertaining to hardware, software or network operation elements, catalogued in an administration information base (11) and with each of which is associated a formal language specification, the system comprises a translator module (10). The module (10) is designed to generate on the basis of the specification for each object, a pair of words the value of whose first word pertains to an indication of the object and the value of whose second word pertains to an information length of the object. The module (10) is also designed to generate one or more templates comprising an ordered set of pairs of words and an identifier, making it possible to subsequently send an ordered string of information corresponding to each template.
