Traceroute Express tiny ver 1.2.0.0

One of the first things people often assume when they're unable to reach their websites or email is that the server their account is on is down. What they don't realize is that there are a great deal of other factors that may be causing a disruption of service.

These are all symptoms of network latency and packet loss, and it's often hard to determine where the problem originates.

Traceroute-express tiny is a small, simple and reliable Windows based tracert/traceroute software to display path that network packets take when travelling across the networks.

Excellent tool for network troubleshooting, this utility incorporates the functionality of well known tracert and traceroute command line utilities and presents the trace information with a Windows based interface.

Traceroute-Express tiny allows you to understand the network, and hunt up problems by taking raceroute, ping, location lookup. The many graphical aspects make it easy to rapidly analysis where a problem is occuring and what the problem is. It supports very simple but powerful fuctions.

Easy to use versatile program that combines ping, WHOIS and traceroute functions into one friendly GUI utility. Using this tool you can identify the source of Internet connectivity problems, track down the source of junk mail, find out a geographic location of a web server or your ICQ buddy, troubleshoot e-mail problems and more

High performance

Traceroute-Express enhanced traceroute application for Windows. It is faster than standard "tracert.exe".

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. Traceroute-Express 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.
