Abstract
Variations in latency, out-of-order, and duplication may occur for incoming packets delivered via a network including a constellation of low-Earth orbit (LEO) satellites. An incoming packet that comprises time data and a sequence number is received at a user terminal. A delivery deadline time (deadline) is determined for the incoming packet. The incoming packet and its deadline are stored in a waiting buffer. Packets from the waiting buffer are processed for storage into 'slots' that correspond to sequence numbers of the incoming packets. A window designates which portion of the slots may be written to or read from. The window may comprise a circular buffer. The window may be “moved” relative to the slots based on sequence number of an incoming packet, highest packet transmitted, maximum permitted movement, lowest window stop, highest window stop, and so forth. Packets in slots within the window that have reached their deadline are sent.
