Abstract: A system of route target filtering includes an import filter receiving a plurality of routes having a next hop routing information. The import filter accepts a first subset of the routes according to an import target policy. The system further includes a re-export filter also receiving the plurality of routes. The re-export filter modifies the next hop information of a second subset of the routes, and distributes the modified routes.

Abstract: A system and method for topology constrained Quality of Service (QoS) provisioning between a plurality of sites in a Virtual Private Network (VPN) is disclosed. The method comprises enabling graphical definition of relationships between the plurality of sites of the VPN and enabling graphical definition of at least one QoS rule for at least one pair of sites of the plurality of sites of the VPN based at least in part on the defined relationship.

Abstract: A system and method for topology constrained routing policy provisioning between a plurality of sites in a Virtual Private Network (VPN) is disclosed. The method comprises enabling graphically defining of relationships between the plurality of sites of the VPN; and automatically generating at least one routing rule for each site of the VPN based at least in part on the defined relationship.

Abstract: Methods and apparatus are provided for processing messages for access to information stored in an open directory. A Lightweight Directory Access Protocol (LDAP) LDAP Validation Proxy (LVP) is used to intercept LDAP request messages intended for the directory, validates the LDAP requests according to a schema description and optionally provides side-effects. The schema validation and LDAP message processing is modularized according to object classes representing the data stored in the directory and according to services provided. The schema is enforced by validating LDAP messages. This modularization provides a controlled message processing granularity and enables multi-threaded concurrent processing of multiple LDAP messages. The LVP has the capability of generating LDAP requests in processing LDAP messages. The LVP also intercepts and processes LDAP responses issued by a directory and intended for clients.

Abstract: A potable electronic test instrument is adapted for the automatic testing of semiconductor diodes regardless of the orientation of the diode relative to the test probes. The test instrument supplies an a.c. sine wave test voltage coupled to the test probes. The maximum negative voltage and the maximum positive voltage are measured and compared against a set of predetermined open and short circuit values to obtain a decision of open, short, or ok for each value. The combination of the two comparisons is used to determine the device status according to a decision criteria. The diode status is accordingly displayed on the graphical display of the test instrument, indicating the device is open, shorted, a diode with a forward orientation or a reverse orientation with respect to the test probes, or of an unknown type. The diode forward bias junction voltage is displayed regardless of its orientation.

Abstract: An electronic test instrument adapted for displaying only meaningful information notwithstanding the intermittent arrival of valid input signals due to probing operations is provided. Two independent measurement processes measure the input signal simultaneously. The first measurement process operates in a similar fashion to a digital storage oscilloscope (DSO) by successively sampling the input signal to produce waveform information which are selectively sent to an LCD display device which graphically displays the waveform. The second measurement process continually performs a stability assessment of the input signal by collecting a series of stability measurements of a selected input signal parameter, creating a moving average of the series, and comparing each new stability measurement to the moving average relative to stability criteria.

Abstract: Methods and apparatus are disclosed for using current detection in a test instrument to ensure validity of component test output. In a component test instrument that employs digital synthesis of a test stimulus waveform, voltage scan data and current scan data are successively acquired, the scan data being synchronized relative to the test stimulus waveform. The voltage and current scan data are stored in respective temporary storage buffers. Before displaying the data, a check for an open lead is conducted in a manner similar to a current scan. A zero current value indicates an open lead and the acquired scan data is disqualified from being displayed. Similarly, at the beginning of a component test operation, an open lead test is performed and the first voltage scan is deferred until a validity check confirms that the test leads or probes are in place. The disclosed methods and apparatus ensure that only valid data is displayed to the user.
