Network operation quality is among the functions to be fulfilled in order to offer QoS to the end user. It is characterized by four parameters: packet loss, delay, jitter or the variation of delay over time, and availability. Resource management employs mechanisms that enable the first three parameters to be guaranteed or optimized. Fault management aims to ensure continuity of service.
Andre Perez is a consultant and trainer in networks and telecommunications who defines the implementation of operator networks. He also teaches QoS technologies in engineering schools.
