Abstract: Tools and methods in which user interaction via a common user interface enables the assessing of network security prior to implementation of the network, as well as assessing the security of existing networks, portions of existing networks, or modifications to existing networks. A network security model useful in realizing the tools and methods is also disclosed.

Abstract: A method and apparatus for managing a network includes detecting occurrence of a network event associated with a new network condition including unplanned and planned macro-events associated with network elements and communication links of the network. The network event is classified as being associated with at least one of a network element failure, communications link failure, and a security breach. In response to the network event exceeding a network degradation threshold, the network event is identified as a network degradation event, and an alert is sent to a network administrator to normalize the network degradation event.

Abstract: A method and system for test data generation, reception, synchronization and analysis of multiple channels within a multiplexed data stream is described herein. Latches on the parallel inputs and outputs of the test data generation shift registers shuffle shift register values for individual channels in and out of memory at the appropriate time in the time division multiplexed (TDM) data stream. State machine control circuitry is used to generate the complex control signals. State machine control memory is a dual port memory, allowing the control signals to be modified as testing requirements vary. This allows various types of analyses for different channels within the TDM data stream simultaneously. A generator dual port memory allows analysis of different types of test data in each channel within the TDM data stream. Results are acumulated in the results dual port memeory and are accessed by a microprocessor for further processing and display.
