In this article we will discuss Quality of Service (QoS), will make brief discussion on Quality of Service (QoS), In last article we discuss about Network Security.
Quality of Service (QoS) is also an ever increasing requirement of networks today.
New applications available to users over internetworks, such as voice and live video transmissions, create higher expectations for the quality of the delivered services.
Have you ever tried to watch a video with constant breaks and pauses? As data, voice, and video content continue to converge onto the same network, QoS becomes a primary mechanism for managing congestion and ensuring reliable delivery of content to all users.
Congestion occurs when the demand for bandwidth exceeds the amount available. Network bandwidth is measured in the number of bits that can be transmitted in a single second, or bits per second (bps). When simultaneous communications are attempted across the network, the demand for network bandwidth can exceed its availability, creating network congestion.
When the volume of traffic is greater than what can be transported across the network, devices queue, or hold, the packets in memory until resources become available to transmit them. One user is requesting a web page and another is on a phone call. With a QoS policy in place, the router can manage the flow of data and voice traffic, giving priority to voice communications if the network experiences congestion.
I am Hamza arif, and i am excited to learn new things, i am well focused for my work and always try to explore new things. My graduate is in BS (Telecom) and i am expert in Networks and working on new technology is my passion i work a lot on AI (Artificial Intelligence) Augmented Reality and many other projects.
