METHOD FOR PATH REDUNDANCY ASSESSMENT IN A BACKBONE NETWORK

摘要

The invention relates to a network monitoring unit for path redundancy assessment of communication links in a backbone network (500). The network monitoring unit is designed to receive meta-data, signatures and/or time stamps detected at transfer points, to identify a pair of logically redundant communication links using the meta-data, signatures and/or time stamps, to generate information tables (320, 320') for the identified communication links (AC, AC') by merging said meta-data, signatures and/or time stamps, and to evaluate the information tables (320, 320') with respect to correlation (E4) of the meta-data, signatures and/or time stamps.
