Abstract
Physical Layer and Data-Link Layer data are connected with Networking through Application Layer data/information to enable searching, sorting, and identification of novel relationships between signal sources and their contents. Metadata can be used at the Physical Layer in an optical fiber network, connecting with metadata generated at the Data Link Layer, connected to metadata generated at the Network to Application Layer. The Physical Layer metadata is obtained from configuration and provisioning data within an Intelligent Optical System. The Data-Link Layer metadata is obtained from a signal processing device. The Network through Application Metadata is obtained from a packet capture or flow capture probe. The metadata from all layers are linked in a data store such that the network traffic, passing through stream(s) in optical fiber(s) layer data are combined. The effect of that combination enables security, intelligence, surveillance, or network analysts to separate application and network information by original source.
