Physical adjacency detection systems and methods

An adjacency detection system configured to detect physical interconnection between two devices in a network, the adjacency detection method comprising:

• a network interface communicatively coupled with one or more controllers associated with the network;
• a processor communicatively coupled to the network interface;
• and
• memory storing instructions that, when executed, cause the processor to
• obtain data associated with the network from the one or more controllers,
• for a given port on a device in the network to detect a corresponding port at another device physically connected thereto, cause orchestration of changes in performance monitoring data for the given port over a period of time, wherein the changes in performance monitoring data comprise a modification of transmit power of the given port over the period of time to send a bit pattern that comprises data that identifies the given port, wherein the transmit power is modified while the port operates in-service and a specific power level is used for a 1 bit, a 0 bit, and a framing bit, and
• analyze the data subsequent to the orchestration to detect the corresponding port, wherein the changes and analysis are performed by a higher-layer application associated with the one or more controllers providing vendor independence and layer independence.

A multi-layer network, comprising:

• a plurality of network elements interconnected to one another at a plurality of layers;
• one or more controllers communicatively coupled to the plurality of network elements;
• and
• a server communicatively coupled to the one or more controllers, wherein the server is configured to
• obtain data associated with the network from the one or more controllers and data sources,
• for a given port on a network element in the network to detect a corresponding port on another network element physically connected thereto, cause orchestration of changes in performance monitoring data for the given port over a period of time, wherein the changes in performance monitoring data comprise a modification of transmit power of the given port over the period of time to send a bit pattern that comprises data that identifies the given port, wherein the transmit power is modified while the port operates in-service and a specific power level is used for a 1 bit, a 0 bit, and a framing bit, and
• analyze the data subsequent to the orchestration to detect the corresponding port, wherein the changes and analysis are performed by a higher-layer application associated with the one or more controllers providing vendor independence and layer independence.
