The time it takes for all these events to complete is known as latency. With this, the latency cycle is completed. The request reaches your browser and the product gets added to your cart.The site’s server replies to the request with relevant information.The request gets accepted or rejected and processed.The site’s server acknowledges the request and the first half of the latency is completed.

The request travels to the site’s server with all the relevant information.The browser identifies this as an event and initiates a request to the website’s servers.The chain of events that occur when you press that button are: Consider that you are buying a product through an online shop and you press the “Add to Cart” button for a product that you like. Let’s look into how latency actually works and how, as a user, you’re usually impacted by it. These private networks reduce latency by providing more efficient paths for data packets to travel on. It can also be reduced by using dedicated networks that streamline the network path and provide direct communication between nodes.Ĭontent Delivery Network (CDN) providers such as StackPath provide customers with private networks that allow them to bypass the public internet. Latency can be reduced by addressing the aforementioned components and ensuring that they are working correctly. Storage delays: Accessing stored data can increase latency as the storage network may take time to process and return information.Router to router hops can increase latency. Routers: The efficiency in which routers process incoming data has a direct impact on latency.Theoretically, latency of a packet going on a round trip across the world is 133ms. In actuality, such a round trip takes longer, though latency is decreased when direct connections through network backbones are achieved. Propagation: The further apart two nodes are the more latency there is as latency is dependent on the distance between the two communicating nodes.For instance, old copper cable-based networks have a higher latency than modern optic fibers.

Transmission medium: The physical path between the start point and the end point.

There are four main components that affect network latency, including: It depends on several aspects of a network and can vary if any of them are changed. Latency is generally measured in milliseconds (ms) and is unavoidable due to the way networks communicate with each other. Latency is the delay between a user’s action and a web application’s response to that action, often referred to in networking terms as the total round trip time it takes for a data packet to travel.
