Measurement of key network performance metrics like: one-way latency, jitter, and microbursts with distributed inline passive probes. The features of the passive latency probes include:
- Passive optical bypass ensures no impact on production traffic even if power is lost
- Accurate hardware time stamping immediately at the wire before any buffering, queuing, or aggregation
- Clock synchronization to an external reference and real time diagnostics of accuracy
- Tunneling and forwarding of prefiltered data to a remote analyzer
- Modular architecture and deployment model for multi-point measurement
In addition to passive probes, cPacket also offers active probes, which inject a time stamp on-the-fly to the on going traffic into a reserved protocol field (more information about this unique and proprietary feature is available upon request).
cPacket latency probes and accurate measurement rely on cPacket's unique hardware-software architecture and its radical algorithmic fabric on a chip, which deliver deterministic performance under any traffic conditions.
