Abstract: A method of providing topology information about a network to a topology manager is disclosed. The network includes a plurality of sensors each having a sensor ID, and the method includes performing the following steps at each of the plurality of sensors: receiving a stream of packets and identifying a topology trace packet in the stream of packets, wherein the topology trace packet has a destination address and an ID of a previous sensor, including the sensor ID in the topology trace packet, sending the topology trace packet to the destination address, forming a report message so as to include the sensor ID, the previous sensor ID, sending the report to the topology manager; and, providing network addresses of adjacent nodes to the topology manager.

Abstract: A method of network testing relies on communication with an unaddressed test device. The method includes collection of network addresses from packets passing through the test device and a discovery procedure. The collected addresses are provided to a remote control device, and used for communication between the test device and the control device.

Abstract: A method of protecting memory locations in an embedded system using a write filter. The method includes the steps of starting a write filter that intercepts writes to the protected memory locations and stores the writes in a cache; starting a state machine with a change state and a normal state; upon starting the state machine, entering the change state when an indication is present that data needs to be persisted to the protected memory otherwise entering the normal state; in the normal state identifying critical writes to the protected memory and creating at least one update file containing the changes in such writes; and in the change state, applying the changes in the update file and rebooting the system in a manner that persists the changes to the protected memory.

Abstract: A system operatively connected to a network and method thereof includes a voice quality tester (VQT) to generate a calling signal and an automated voice responder unit (VRU) to receive the calling signal. The autonomous VRU and the VQT include a first task list and a second task list, respectively, allowing the autonomous VRU to synchronize with the VQT and perform a series of voice quality tests of the network without any external I/O control.
