Abstract
Disclosed in some examples are methods, systems and machine readable mediums to efficiently stream data across restricted networks. In some examples, this streamed data may be sent more efficiently using lower overhead protocols such as UDP. In order to bypass the aforementioned limitations on these lower overhead protocols, the client may send a periodic update message to the server. This update message maintains the openings in the network firewalls and updates the server on the client's status. This update message may be sent much less frequently than a typical TCP acknowledgement, and the lower overhead protocol may be a protocol that does not retransmit lost or corrupted packets—thereby eliminating unnecessary overhead. In some examples this streamed data may be GNSS correction data. In some examples, the client may be behind one or more network firewalls.
