QXM-QoS
Assuring a great customer experience is a must in today's increasingly competitive environment. Service providers and enterprise communication managers alike can utilize QXM-QoS, a proactive, distributed monitoring solution, to verify voice quality in IP-based networks. It is a cost-effective, easy to install and scalable solution designed for rapid return on investment.
With a downloadable software agent, QXM-QoS sends calibrated traffic from the agent to the measurement servers. A centralized server then collects the results of these measurements and assesses service quality throughout the network. Because the agent is downloaded into the PC used by the end-user, the measurements reflect the exact quality score as experience by the user.
QXM-QoS reports:- Round trip delay - total time elapsed from the origin to the destination and back
- Jitter - standard deviation of the time a packet takes to get from the source to the destination
- Bit rate - the amount of bytes transmitted/received on a single time unit
- Session setup time and response time - the time elapsed between the request and the response
- Session failure rate - the ratio between the number of sessions that fail vs. the number of sessions attempted
- Packet loss rate - percentage of packets lost for each session
- Benchmarking terminology for network interconnection devices
- IETF RFC 2544
- IETF RFC 1242
