SELECTIVE QUIC DATAGRAM PAYLOAD RETRANSMISSION IN A NETWORK

Embodiments of the invention provide methods, apparatus, and media to perform selective QUIC datagram payload retransmission. In one embodiment, a method is performed by a proxy network device that is on a path between a first and a second peer network device. The method includes determining, for an end-to-end packet-based traffic flow between the first and second peer network devices, a first duration to perform traffic forwarding between the first peer network device and the proxy network device, and a second duration to perform traffic forwarding between the proxy network device and the second peer network device. The method further includes, based on the first and second durations, causing retransmission of an end-to-end packet embedded as a pay load of a QUIC datagram, where the end-to-end packet was previously transmitted between the first peer network device and the proxy network device.
