Abstract: Systems, methods, and non-transitory computer-readable storage media for translating source addresses in an overlay network. An access switch in an overlay network, such as a VXLAN, may receive an encapsulated packet from a tunnel endpoint in the overlay network. The encapsulated packet may originate from a host associated with the tunnel endpoint and be encapsulated at the tunnel endpoint with a first source tunnel endpoint address and a destination tunnel endpoint address. The access switch may replace the first source tunnel endpoint address in the encapsulated packet with a second source tunnel endpoint address of the access switch to yield a translated packet. The access switch may then transmit the translated packet towards the destination tunnel endpoint address.

Filtering is performed by adaptive filters with suppressed side lobes adjustable in the time domain and widths of main lobes adjustable in the frequency domain to improve detection of signals on the shortest path of arrival or line-of-sight (LOS) path while mitigating the effects signals received from longer paths of arrival or non-line-of-sight (NLOS) paths.

Abstract: In examples, Radio Frequency nodes of an array are synchronized using Time-Reversal. A Master node (“Master”) of the array receives and captures a sounding signal emitted by a Slave node (“Slave”) of the array, downconverts it to baseband, Time-Reverses the downconverted signal, upconverts the Time-Reversed signal to the carrier frequency using the Master's clock so that the upconverted signal has phase property of the Master's clock, and transmits the resulting signal to the Slave. The Slave receives the signal from the Master, and adjusts the phase of the Slave's clock so that the phases of the two nodes are aligned. Once phases, frequencies, and time references of the array's nodes are aligned, the array may be used for coherent operation. In examples, the array is used to transmit Time-Reversed signals so that the signals from the array's nodes are spatially and temporally focused on a target.

In response to receiving a packet associated with an OAM operation from a device in an overlay network, the system generates an OAM packet. The system can be coupled with the overlay network and can include a tunnel endpoint interface associated with an underlay address and a virtual interface associated with an overlay address.

Next, the system determines that a destination address associated with the packet is not reachable through the virtual interface, the destination address corresponding to a destination node in the overlay network. The system also determines that the destination address is reachable through the tunnel endpoint interface. The system then provides the underlay address associated with the tunnel endpoint interface as a source address in the OAM packet.
