Abstract
The method is for monitoring a computer network comprising switches and end devices defining a network architecture, each switch comprising a plurality of connection ports. The method comprises: - an acquiring step to acquire a current network status of each switch, including for each connection port a connection data indicating whether another switch or an end device is connected to the connection port and optionally an identification data of said switch or end device connected to the connection port; and - a comparing step to compare the current network status with a reference network status to detect an abnormality of the computer system.
Claims16
Method for monitoring a computer network located onboard a vehicle, for example a train, the computer network comprising a plurality of switches and a plurality of end devices connected together with defining a network architecture, each switch comprising a plurality of connection ports, each switch being connected to one connection port of at least one other among the plurality of switches and each end device being connected to one connection port of one of the switches,
- characterized in that the method comprises the following steps implemented by a network management system provided onboard the vehicle:
- an acquiring step to acquire a current network status of each switch among the plurality of switches , the current network status of each switch including for each connection port of each switch a connection data indicating whether another switch or an end device is connected to the connection port and an identification data of said switch or end device connected to the connection port;
- a comparing step to compare the current network status with a reference network status to detect an abnormality of the computer system.
- Method according to claim 1, wherein the method comprises an emitting step to emit a notification upon detection of the abnormality.
Method according to claim 4, comprising a step of evaluation, wherein a compromise value is calculated representing a level of abnormality, the compromise value being incremented upon detection of each additional abnormality.
Computer system provided onboard a vehicle, for example a train, the computer system comprising a computer network comprising a plurality of switches and a plurality of end devices connected together and defining an network architecture, each switch comprising a plurality of connection ports, each switch being connected to one connection port of at least one other among the plurality of switches and each end device being connected to one connection port of one of the switches,
- characterized in that it comprises a network management system (NMS) provided onboard the vehicle, the network management system (NMS) comprising:
- an acquisition module adapted for acquiring a current network status of each switch of the plurality of switches, the current network status of each switch including for each connection port of the switch a connection data indicating whether another switch or an end device is connected to the connection port and an identification data of said other switch or said end device;
- and
- a comparison module adapted for comparing the current network status with a reference network status to detect an abnormality of the computer network.
