the interpretation of metrics for the same managed objects.
• Measurement domains right and left of the peering points are supported by different service provid-

Figure 4.5.8 shows routers as a peering point. In this case, there are two networks terminated with the
router, respectively. Routers are owned by the service provider and connected back-to-back. The rules
and alternatives are as follows:
