    Abstract: A method for detecting dropped packets in a network that includes a packet switched network. The method includes establishing a telephonic connection between a first network location and a second network location (400). A set of N waveforms are transmitted from the first network location (404). Each waveform includes a characteristic operative to assign a predetermined value relative to other waveforms in the set of waveforms, such that a predetermined sequence of values are assigned to packets carrying the N transmitted waveforms. A telephonic signal is received at the second network location (406'). The signal is processed to obtain a received sequence of values (412), and the received sequence of values is used to detect dropped packets without having access to packet switched network control data (418).

    Abstract: To verify the integrity of optical paths through and among optical switches, optical signals are provided with co-propagating supplemental signals. The supplemental signals preferably have at least one characteristic which allows distinguishing one supplemental signal from another. Associated with a port of a switch, means are provided for detecting a supplemental signal and determining if the supplemental signal indicates that a desired optical signal is passing through the port as expected and desired. Means for imparting or changing the distinguishing characteristic of a supplemental signal may also be employed to facilitate verifying the passage of optical signals.

    Abstract: A system for malicious code detection includes a front-end processor (110), multiple scanning computer systems (122, 124, 126), and a detection management system (130). During operation, the multiple scanning computer systems (122, 124, 126) scan content for malicious code and generate an alarm when the content contains malicious code. The front-end processor (110) receives a flow of content from an external network (100) and distributes copies of the flow to each of the multiple scanning computer systems (122, 124, 126) in parallel for scanning. The detection management system (130) employs a countermeasure on the flow if at least one of the scanning computer systems (122, 124, 126) generates the alarm.
