Ingress points localization of a flow in a network
First Claim
1. A detection device of flow of data packets (DD) for an edge equipment element (RP) of a communication network (N) equipped with a network management system (NMS), characterized in that it includes detection means (MA) arranged to compare parameters, contained in the headers of data packets arriving at the ingress interfaces (IE) of the said edge equipment element (RP), associated respectively with interface identifiers, with at least one configuration parameter received from the said network management system (NMS) and associated with a parameter identifier, and, in the event that a header parameter of a data packet received at one of the said ingress interfaces (IE) is identical to the said configuration parameter, of generating an alarm message intended for the said network management system (NMS), where this message includes the identifier of the ingress interface (IE) having received the said data flow and the said parameter identifier.

Abstract
A data flow detection device (DD), for an edge equipment element (RP) of a communication network equipped with a network management system, includes detection means (MA) tasked to compare parameters, which are contained in the headers of data packets arriving at the ingress interfaces (IE) of the edge equipment element (RP) associated respectively with interface identifiers, with at least one configuration parameter received from the network management system. In the event where a header parameter of a data packet received at one of the ingress interfaces (IE) is found to be identical with the configuration parameter, the detection means (MA) generate an alarm message, intended for the network management system, where this message includes the identifier of the ingress interface (IE) which has received the data flow and the identifier of the configuration parameter.

16. A location management process for a communication network (N) which includes edge equipment (RP), equipped with ingress interfaces (IE) capable of receiving flows of data packets and associated respectively with interface identifiers, characterized in that it consists of:
-
determining at least one configuration parameter representing a data flow to be detected and associated with a parameter identifier, configuring chosen edge equipment (RP) in the said network (N) so that they compare parameters, contained in the headers of data packets arriving at their ingress interfaces (IE), with the said configuration parameter, and so that, in the event of a header parameter of a data packet received at one of their ingress interfaces (IE) being identical to the said configuration parameter, they generate an alarm message, intended for a management system of the said network (NMS), where this message includes the identifier of the ingress interface (IE) having received the said data flow and the said parameter identifier, and in the event of receiving an alarm message coming from an edge equipment element (RP) and which includes an ingress interface identifier (IE) and a configuration parameter identifier, of transmitting a message to the edge equipment (RP) concerned requiring that detection of the data flows which includes the said configuration parameter should be stopped.
