Just as an example, customer QoS monitoring is a business level issue, but such QoS parameters like the packet loss ratio or the round trip delay in an IP network are often evaluated by the same system that monitors the IP traffic at the network level; in the same way, how a fault in a network node can affect the service provided to a given customer is often evaluated by the Network Fault management system, etc. In other words, some of the Service and
