Network dictionary: PING and PONG

Jenz3333 on the question of platform Cosmiq asks "What is the ping?". Reiniroas just responds: "Time, which needs a data packet from you in milliseconds (in ms) to the server and back again."

We want to see then yet once more that. The travel time of the data package is the latency or delay. She will be determined using the so-called PING request. The PING, a test signal - more accurate a package of 64 bytes, is sent from the Smartphone to the server over the network and then it sends a response packet PONG, called. How quickly this is done, says of course also something about the network speed. This package rotation is known as round trip time, RTT, and measured in milliseconds. It is equivalent to the latency. The PING is the control, if a computer on a network is reachable.

From the submarine in the modern mobile radio network

It works like a sonar, the name PING comes in fact from the noise that is caused in a submarine by sonar. With every mobile phone system generation, GSM via UMTS to HSDPA, latency has improved very clearly so mobile surfing pleasure correctly. Particularly gamers benefit as the online games need quick feedback from the server for each action. The answer arrives at not fast enough, then shoots and moves the character rapidly, the gamer is easily from the game. A good 100 ms latency is mobile really fast. We have tested with us on the lutea with the app "Net Ping" and it reached 139 ms. But it works also, depending on the game, if it runs slower, so Sukram69 in RIFT-Forum: "The ping is but mostly to the 400(ms) - the game comes out but still perfectly playable me."

What latency you have pinged?

Do you already have experience with the mobile Internet, the PING and mobile games? We look forward to your comments.
