Abstract
The Internet is developing from a data network supporting best-effort service to a network offering several classes of service. An operator of an IP-network should monitor the achieved QoS for each class using suitable measurement points and measurement methods. The paper compares briefly IPPM and I.380 IP-level QoS (Quality of Serv- ice) -parameter definitions and points out their problems: the selection of the measurement points and the use of test traffic based measure- ments. The paper gives more suitable definitions for QoS and GOS (Grade of Service)-parameters for the IP level, discusses measurement issues of loss and transfer rate, proposes and illustrates via an example a network management based QoS-monitoring system.
