In this video we’re going to take a vendor-neutral look at what it does, and how it works QoS is a group of technologies that improve the performance of selected network applications. Put simply, if your network is congested, it decides which packets are important, and which aren’t. QoS won’t prevent traffic from dropping, but it will prioritise the important traffic over the rest. When it comes to traffic, we need to understand bandwidth, loss, latency, and jitter. Bandwidth is the amount of data transferred per second. Loss is where packets do not reach their destination. Latency is the time for packets to pass between two endpoints. And jitter is the variance in latency. QoS identifies certain traffic and categorises it. For example, one category might have voice traffic, and another might be for web browsing. Once traffic is organised into categories, each category can be treated differently. Let’s not forget ‘Class of Service’. This is a specific technology that operated at layer-2, handling ethernet frames rather than IP Packets. This is still under the umbrella of QoS. Overview of this video: Introduction What is QoS?
