| VoIP ANALYSIS | |
| VoIP Simulation Test • All editions |
UDP VoIP traffic is simulated between your server and the browser client, diagnostic tests are performed to measure the critical factors that impact VoIP connection quality. |
| MOS Score • All Editions |
MOS is a numeric measure of the sound quality
of a communication connection. Although the score
is subjective it provides a widely-used method
to rate the quality of voice communication. The score is normally between 1 and 5 with 5 being the best. In MyVoIPSpeed, a VoIP simulation that drops below 3.5 is considered poor quality, a measure of 4.2-4.5 is considered good quality. |
| Jitter • All Editions |
Jitter is a key factor in assessing VoIP connection
quality. Jitter is the variation in time between packets sent and packets arriving caused by network difficulties such as route changes, congestion, packet loss, traffic regulators etc., and plays a major role in the quality of a VoIP call. VoIP works by sending voice data as a stream of packets from source to destination. These packets can take a varying amount of time to reach the destination and invariably do not arrive in the order in which they were sent. For a VoIP telephone call to work well the packets sent from the source must arrive within a certain time window (or ‘buffer’) in order for the receiving end to reassemble the packets in the correct order and reproduce the spoken words. When there is excessive jitter the time delay is too long (high latency) and packets arrive outside the time window and get lost from the call, or ‘discarded’. As a result, the recomposed sound no longer reflects exactly what was sent, and depending of the extent of the delay may not be understandable by the recipient. |
| Packet Loss • All Editions |
Packet loss plays a key role in the quality
of VoIP connections, as high packet loss causes
some of the voice data not to arrive to the recipient.
Packet loss occurs when voice packets are discarded
by the jitter buffer, or dropped by network routers/switches
due to high congestion. MyVoIPSpeed measures the percentage of packet loss and reports the associated level of sound quality. For more accurate results Packet Loss is measured in one direction only, which is normally not possible using traditional methods such as ping, where routing can affect the reply. |
| TraceRoute Analysis • NOC Edition |
The NOC Edition includes RTA (remote
test agents) that can be deployed to multiple remote
systems for automated VoIP and bandwidth testing.
The RTAs can run traceroute tests and report
the diagnostic information to the central performance
database. . Internet connections involve multiple networks and device, and the routing path between 2 points can change frequently, complicating the process of pinpointing connectivity problems. Traceoute analysis is extremely useful in identifying the network device or segment that is causing poor performance. |
| Advanced Statistics • Professional & NOC Editions |
The Advanced Statistics report tab provides
a summary of the above test results for each
VoIP simulation test, along with more detailed
statistics including:• Jitter: from server to client |
