Abstract: In one embodiment of the present disclosure, a device for detecting a zone of communication between a user terminal and a satellite constellation including a plurality of satellites in non-geosynchronous (non-GEO) orbit includes one or more processors and memory. The memory stores instructions that, as a result of being executed by the one or more processors, cause the device to: determine a location of the device, wherein the location corresponds to a field of regard for detecting the zone of communication, and wherein the field of regard corresponds to an antenna aperture of the phased array antenna; evaluate a level of communication between the phased array antenna and the satellite constellation associated with the field of regard; and output, to a user of the device, an indication of the level of communication between the phased array antenna and the satellite constellation associated with the field of regard.

Abstract: A networking manager of an extension server of a virtualized computing service detects that a data link layer frame has been obtained at the extension server. The networking manager delivers at least a portion of contents of the frame to a compute instance running at the extension server in response to determining that a destination media access control (MAC) address of the frame matches a MAC address of a local-premise-access virtual network interface attached to the compute instance. The local-premise-access virtual network interface is not assigned an Internet Protocol (IP) address from a range of IP addresses managed by the virtualized computing service.
