Network latency is the delay in data transmission between two points, which can be measured by round-trip time. Factors contributing to latency include transmission medium, propagation distance, and hardware delays. Upgrading hardware can improve network performance.
Network latency is simply defined as the time delay observed in the transmission of data from one point to another. Typically, the origin and destination points are used to determine this delay. In some cases, network latency can be defined by the time it takes for some form of data to make one complete circuit back to its point of origin.
While it may seem counterproductive to use round trip time, it can actually be a much better measure of overall network performance. This is because computers in the process of sending and receiving bytes are in constant communication with each other. The receiver will also send information to the sending machine. Therefore, latency can easily be determined from the round-trip time.
The main assumption of network latency is that the transmission time between the source and destination should be instantaneous. Of course, there will always be some delay. Transmission at the speed of light is also not instantaneous and can be measured with very precise instruments. Therefore, delay data should always be available.
There are a number of factors that contribute to network latency. These include broadcast, propagation, router and computer hardware delays. In some cases, there may not be a delay that the user can notice. Fortunately, if latency becomes an issue, there are things that can be done to improve the situation.
In network latency, transmission refers to the medium used to transmit information. This could be a phone line, a fiber optic line, or a wireless connection, just to name a few examples. Each will contribute in some way to the delay. Some may be faster means than others. To reduce latency, it may be possible to change the medium to a faster type.
Propagation is one of the hardest things to control in network latency. Simply put, this is the physical distance between the origin and the destination. Naturally, the greater the distance, the more delayed the transmission will be. However, this usually doesn’t cause a significant delay.
The other factors that contribute to network latency, routers and computer hardware can be changed. In these cases, upgrading this hardware can help process information faster, thus speeding up the process. While this may involve a substantial investment, the benefits can be well worth the investment, depending on the amount and frequency with which data is transferred.
