Understanding Quality of Service: IP, ATM, DiffServ, and MPLS
The Understanding Quality of Service: IP, ATM, DiffServ, and MPLS course provides students with the knowledge of Quality of Service (QoS), which may well be one of the most confusing and elusive topics in data networking today. QoS is a broadly-used term that refers to the performance attributes of an end-to-end connection. The particular elements of a QoS definition depend on the information being transported. For example, QoS for voice defines limits on specific parameters such as delay, signal loss, noise, and echo. The definition of QoS for data may identify attributes such as error rates, lost packet rates, throughput, and delay. In many cases, particularly in data networks, differing levels of QoS are supported by the same network.
