Abstract: Techniques for a TCP proxy to communicate over a LEO satellite network on behalf of a client device by selecting a TCP congestion-control algorithm that is optimal for the LEO satellite network based on the time of day and/or location of the TCP proxy. Based on the locations of satellites during the day as they traverse predefined and patterned orbital paths, different TCP congestion-control algorithms may be more optimized to communicate data through the LEO satellite network. However, client devices generally use a single TCP congestion-control algorithm to communicate over WAN networks. Accordingly, a TCP proxy may be inserted on, for example, a router to communicate with the client device using a TCP congestion-control algorithm that the client device is configured to use, but then communicate over the LEO satellite network using a different TCP congestion-control algorithm that is optimal based on the time of day and/or other factors.
