TT or Round Trip Time

Among factors that are used tointerpret connection speed test results, RTT or Round Trip Time is animportant element. The RTT is the time taken for your machine to senda small packet during the test and receiving it back after it hasmade a round trip in the network path being tested. It is measured inmilliseconds (ms). The less it is, the better is the connection. Itis explained by experts that for VoIP, it is OK to have a RTT of lessthan 250 milliseconds. Another factor is Max Pause which is thelongest pause your test has recorded between data packets. For a goodbandwidth, this should be a very small number; else, it wouldindicate that there could be problems of consistency in yourconnection. Any max pause below 100 is good for VoIP to have a goodquality international long distance calling . Also, as with the typesof speed tests online, you should know that not all speed tests aregood. But, it is pointed out by experts that out of the few goodones, some stand out, with sophisticated algorithms that yield moreaccurate results, interesting features and nice visual interfaces.One of the important speed test online is termed as Speedtest.netwhich is the favorite of many people. It is much enhanced and gives alot of features, including a very user-friendly choice of servers;comparing and sharing results with others, detailed result parametersetc. the advanced user interface is what many people find mostinteresting with this engine.
