IPC Code(s): H04B7/185
CPC Code(s): H04B7/18513
Abstract: techniques for a low earth orbit (leo) satellite to route data through optimal satellite paths based on latency thresholds (and/or other qos thresholds) for the application generating the data. the leo satellite may identify the latency threshold from a data packet, where the latency threshold indicates an amount of time for the data packet to be relayed back down to a destination ground device. the leo satellite determines available satellite paths through which data packets may be routed to destination ground stations. further, the leo satellite may determine latencies for transmitting traffic over the available satellite paths. the leo satellite may compare the latency threshold for the data packet with the latencies of the available satellite paths, and select a satellite path that is optimal for transmitting the data packet. in this way, leo satellites intelligently route data through satellite paths based on the type of traffic being transmitted.

IPC Code(s): H04L9/40, H04L61/2521, H04L61/2539, H04L61/4511
CPC Code(s): H04L63/0421
Abstract: techniques for using network address translation (nat), mobile internet protocol (mip), and/or other techniques in conjunction with domain name system (dns) to anonymize server-side addresses in data communications. rather than having dns provide a client device with an ip address of an endpoint device, such as a server, the dns instead returns a random ip address that is mapped to the client device and the endpoint device. in this way, ip addresses of servers are obfuscated by a random ip address that cannot be used to identify the endpoint device or service. the client device may then communicate data packets to the server using the random ip address as the destination address, and a gateway that works in conjunction with dns can convert the random ip address to the actual ip address of the server using nat and forward the data packet onto the server.
