Round Trip Time
Round trip time (RTT) also called round trip delay, is the time required for a signal pulse or packet to travel from a specific source to a specific destination and back again. In this context, the source is the computer initiating the signal and the destination is a remote computer or system that receives the signal and retransmits it.
On the internet, an end user can determine the RTT to and from an IP (Internet Protocol) address by pinging that address.
The result depends on various factors including
- The data transfer rate of the source’s Internet connection.
- The character of the transmission medium (copper, glass fiber, wireless or satellite).
- The physical distance between the supply and therefore the destination.
- the number of nodes between the supply and therefore the destination.
- the number of traffic on the space network computer network LAN (local area network) to that the top user is connected.
- the number of alternative requests being handled by intermediate nodes and therefore the remote server.
- The speed with that intermediate node and therefore the remote server operates.
- The presence of interference within the circuit.
