PingSigma Standard description
PingSigma-Standard is a lightweight network troubleshooting, diagnostic and monitoring tool

PingSigma-Standard is a lightweight network troubleshooting, diagnostic and monitoring tool. It can analyze quality of end-to-end and then allow you to quickly look at the data in an intuitive graphical format when you experience problems (reduced call quality for VoIP, slowdowns or disconnects with applications, etc.).

PingSigma Standard is also great at allowing you to collect data over time to give you the information you really need to identify intermittent problems and allowing you to see both short-term and long-term trends.

PingSigma-Standard allows you to "See the network", and "Pinpoint problems" by taking traceroute, ping, and RTP to a new level. It's fast, and the graphical aspects make it easy to quickly see where a problem is occuring. statistics, and numerous other features give the you the extra power you need to find and troubleshoot problems.

Here are some key features of "PingSigma Standard":

Easy to use
· PingSigma's basic mode means you just type in the address you want information about and hit "Trace". It starts tracing and shows you a graph. Someone with no network experience can see where their packets are being dropped, and then contact their ISP with this information
High performance
· PingSigma-light is very fast and exact. Minimum packet to packet interval time is 5 micro seconds only.
Analysis of jitter distribution
· It has been suggested in voice over IP that an appropriate choice of the distribution used in modeling the delay jitters, can improve the play-out algorithm. In this paper, we propose a tool using which, one can determine, at a given instance, which distribution model best explains the jitter distribution. This is done using Expectation trimming percent, to choose gamma distribution model of the best suited.
Play-out algorithm simulation
· We study the delay characteristics of voice packets that share a transmission medium with bursty data traffic. In order to model the data traffic accurately, we used real data traffic traces upon which we superimposed simulated voice sources generating real time traffic at a constant rate. Our simulation environment allows us to easily develop and compare different adaptive algorithms for the play-out delay of voice streams. We motivate and compare the performance of algorithms based on exponential smoothing techniques.
E-Model & MOS
· Calculate MOS score. Delivered E-Mode, Applying E-model on Ie gives the R factor whose value ranges from 0 to 100 (100 is the best, 0 is the worst). R factor mapping to MOS values is shown at the end. The Ie factor incorporates the effects of codec, jitter, packet loss, packet loss distribution, and recency. The preferred place to passively monitor for these values is the VOIP codec. Here you know the codec type, jitter buffer size, and post-jitter buffer packet loss events. PingSigma is supported 12 codec types(G.711,G.711 PLC,G.723.1 5.3k,G.723.1 6.3k,G.726 16k,G.726 24k,G.726 32k,G.726 40k,G.728 16k,G.729,G.729A,GSM FR (6.10)) and play-out algorithm and etc.
