Systems and methods are provided for implementing a free space optical backplane structure including a body and a plurality of mirrors. The body includes a chamber, a front panel, and a plurality of apertures disposed in the front panel, the plurality of apertures including a first set of apertures and a second set of apertures. The plurality of mirrors includes first and second arrays of mirrors mounted at first and second sets of heights, respectively, within the chamber, and is aligned with the first and second sets of apertures located in the front panel. The first and second arrays of mirrors are arranged to direct laser signals travelling through free space that are transmitted from or to a first device through the first set of apertures, between the first and second arrays of mirrors, and to or from a corresponding second device through the second set of apertures.

Optical transport terminal node architecture with free space optical backplane

Increasing a resolution of an error rate detectable on a link between two network nodes includes transmitting an IP-in-IP encapsulated test packet back and forth between the two network nodes. The test packet includes a series of nested data packets having alternating destinations between the two network nodes. The test packet is transmitted on the data plane of the network, thereby increasing the resolution of the detectable error rate.

A system adapted to identify a router port corresponding to a DWDM device port is disclosed. A port identification server gathers and accumulates time series traffic data for a port of a DWDM device and plurality of router ports. The port identification server compares the time series traffic data for the port of the DWDM device with the time series data for router ports in order to determine which one of the router ports has data transmitted therefrom and received thereat that best fits or corresponds to the data received at and sent from the DWDM port. The port identification server identifies the router port that has time series data traffic that most closely matches the data traffic at the DWDM port as connected to the DWDM port.
