Abstract
A new approach is provided for measuring the impact of network underlay (Layer 3) outages on customer-facing services, such as internal applications (Layer 7) and external cloud virtual machines (VMs). The approach performs a cross-layer impact analysis by correlating low-level network performance data with customer-level metrics within fine-grained time intervals. By comparing performance across layers for the same network path and time, the system can distinguish between L3 outages that are successfully mitigated ("repaired") and those that "surface" to the customer. The resulting metric, "surfaced SLO burn," quantifies the actual customer-experienced outage, enabling more accurate measurement of the issues and better prioritization of engineering efforts toward these issues.
