Description: Link performance refers to the effectiveness of a network link in data transmission, assessing its capacity to transfer information efficiently and quickly. This concept is fundamental in the design and operation of networks, as it determines the speed and quality of communication between devices. Link performance is measured in terms of bandwidth, latency, and packet loss rate, factors that directly influence user experience and application efficiency. A high-performance network link allows for smooth data transmission, which is crucial in environments handling large volumes of information, such as video streaming or real-time applications. Additionally, link performance is a key aspect in the implementation of advanced technologies such as 5G, cloud networks, and Wi-Fi, where the goal is to maximize transmission capacity and minimize disruptions. In summary, link performance is an essential indicator of network quality, affecting both infrastructure and end-user experience.
