Root Cause and Impact Analysis of Metro Ethernet Failures on CE-VLANs

This section describes how the IP Manager, MPLS Manager, Global Manager, and Business Impact Managerwork together to determine how Metro Ethernet failures impact customer VLANs (CE-VLANs). Flow of information to determine how Metro Ethernet failures Impact CE-VLANsshows the flow of information between the Managers to accomplish this end.

• Figure 1. Flow of information to determine how Metro Ethernet failures Impact CE-VLANs

  

  As implied in the figure, Business Impact Managercalculates the impact of EVC events on CE-VLAN ServiceOffering objects, and creates CE-VLAN impact notifications. The CE-VLAN impact notifications enable users to immediately identify disruptions and failures to CE-VLANs due to EVC events, and to prioritize the resolution of the network and MPLS problems in accordance with their business impact.
