Speedtester.info

, is a web service that provides free analysis of Internet access performance metrics, such as connection data rate and latency. it allows users to measure their internet speed for free, along with other services including analysis of mobile and fixed network performance. It measures the Ping, Jitter and Latency of your internet service and also highlight the internet service provide as well including server IP

What is Ping

Ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. It is available for virtually all operating systems that have networking capability, including most embedded network administration software. Ping measures the round-trip time for messages sent from the originating host to a destination computer that are echoed back to the source. The name comes from active sonar terminology that sends a pulse of sound and listens for the echo to detect objects under water. Ping operates by means of Internet Control Message Protocol (ICMP) packets. Pinging involves sending an ICMP echo request to the target host and waiting for an ICMP echo reply. The program reports errors, packet loss, and a statistical summary of the results, typically including the minimum, maximum, the mean round-trip times, and standard deviation of the mean.

What is Jitter

Jitter is the undesired deviation from true periodicity of an assumed periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude, or phase of periodic signals. Jitter is a significant, and usually undesired, factor in the design of almost all communications links (e.g., USB, PCI-e, SATA, OC-48). In clock recovery applications it is called timing jitter.

What is Latency

Latency refers to the span of time taken from when some action is initiated to when it actually takes effect. In the context of packet-switching networks, latency can refer to any of the following:

• The time from when a packet is sent to when that packet reaches its destination
• The round-trip time of a packet
• The perceived delay in communication between hosts

Any packets which are prevented from reaching their destination for any period of time will result in an increase in latency. Heavy network traffic can therefore increase latency, as bandwidth limitations and routing issues contribute to the time that a message spends in transit.
