Systems and methods for managing multi-layer communication networks
A system for mapping a multilayer network having a server layer and a client layer is provided. The system includes a framework configured for comparing information obtained from a first traffic counter of a client port to information obtained from a second traffic counter of a server port to thereby determine if the client port and the server port are linked.
1. A system for mapping a multi-layer communication network having an optical layer and an internet protocol (IP) layer, the system comprising a controller configured to execute instructions for:
receiving traffic data from a first traffic counter located at a port of the optical layer and a second traffic counter located at a port of the IP layer;
calculate correlation between values of the first counter to respective values of the second counter measured in corresponding times; and
determining that the port of the optical layer and the port of the IP layer are connected in case the calculated correlation exceeds a predetermined threshold;
managing communication failures or configuration changes based on the mapping of connections between the optical layer and the IP layer.
2. The system of claim 1 , wherein gaps or delays in the traffic data of a certain measurement time interval are corrected by assessing a correction value for estimation of the correct traffic data of the measurement time interval.
3. A system for mapping a multi-layer communication network having first and second domains of an optical layer, the system comprising a controller configured to execute instructions for:
receiving traffic data from a first traffic counter located at a port of the first domain of the optical layer and a second traffic counter located at a port of the second domain of the optical layer;
calculating a traffic pattern in the port of the first domain and a traffic pattern in the port of the second domain;
comparing the traffic pattern in the port of the first domain to the traffic pattern of the port of the second domain to detect correlation of the traffic patterns; and
determining that the port of the first domain and the port of the second domain are connected in case the detected correlation accuracy exceeds a predetermined threshold;
managing communication failures or configuration changes based on the mapping of connections between ports of the first domain and the second domain.
