Abstract: There is provided a monitoring system for monitoring a plurality of mobile devices registered at a server, the monitoring system comprising the server and the plurality of mobile devices registered at the server, the plurality of mobile devices including a first mobile device, wherein each mobile device is arranged to acquire location data and to send the acquired location data to the server via a telecommunications network, the server storing a time series of location data for each device, wherein the server is configured to generate an alert message identifying the first mobile device in response to a time series of location data from the first mobile device satisfying a condition.

Abstract: Faults are detected and recovered from in a multiprotocol label switching (MPLS) network by communicating packets between a first node and a second node in the MPLS network using a set of prioritized label switch path (LSP) pairs. A failure to receive a relatively constant rate of packets during a predetermined time interval is detected at the first node. Packets are sent from the first node to the second node using a backup LSP pair responsive to detecting the failure. Packets are then sent from the second node to the first node using a backup LSP pair responsive to receiving packets at the second node on the backup LSP pair.
