Claim of US Patent No. 10,191,827

1. A method for utilizing loopback operations to identify a faulty subsystem layer in a multilayered system, the method comprising:executing a plurality of loopback operations using a respective plurality of loopback points positioned among subsystem layers of a multilayered system, wherein:
the plurality of loopback operations incrementally test loopback points in the plurality of loopback points; and
each loopback operation tests loopback points that have been previously tested during previously executed loopback operations;
detecting a failed loopback operation among the plurality of loopback operations; and
identifying a faulty subsystem layer among the subsystem layers by comparing the failed loopback operation against a previously conducted successful loopback operation corresponding to a preceding subsystem layer that is adjacent to the faulty subsystem layer within the multilayered system.
