Abstract: A detection mechanism is disclosed for identifying peers transmitting network traffic towards a cloud provider using routing prefixes that were not advertised for that peer. Once detected, an alarm condition can occur and the peer notified to remove any static route configurations. In one embodiment, a collector server computer can be used to acquire routing prefixes advertised to a peer. A second server computer can be used to obtain network traffic received from the peer. A comparison can then be made between the advertised prefixes and the network traffic being received. If network traffic is being received for unadvertised prefixes, then an alarm condition can occur. The detection mechanism can regularly inspect active traffic flows against BGP route advertisements at fixed intervals. For peers that are identified that are not in compliance with route advertisements, the alarm condition can occur for follow-up remediation.

Abstract: A solid state simulator of an automobile ignition system is disclosed whereby an automotive engine scope tester can be tested and calibrated. Pulse rate logic is made responsive to means for selecting the number of cylinders and the revolutions per minute of the simulated engine. Variable pulse generation means is made responsive to the pulse rate logic. The output of the pulse generation means is used to trigger a driver connected to a conventional coil and single spark plug simulating the firing of all the spark plugs in the engine. Additionally, the output of the pulse generation means is divided and used to drive an adjustable delay which in turn triggers a one shot high voltage pulse to simulate the firing of the spark plug associated with the number one cylinder. Signal output terminals are provided at the input to the coil to indicate the time of each firing signal and allow feedback control by the engine scope tester.
