US 2026/0129000 A1 · METHODS AND SYSTEMS FOR MINIMIZING PACKET RETRANSMISSION AND BANDWIDTH PRIORITY MANAGEMENT AT A USER DEVICE

Abstract

A method for minimizing packet retransmission, performed by a user device, includes determining a foreground application event associated with a foreground application; determining a background bandwidth limit associated with at least one background application; determining whether the background bandwidth limit exceeds a threshold value; based on the background bandwidth limit exceeding the threshold value, identifying a transmission protocol associated with the at least one background application; and based on the identified transmission protocol, controlling packet transmission by delaying egress traffic or adjusting an advertise window size. The method applies different control mechanisms for UDP and TCP protocols, with UDP using egress traffic delay and TCP using advertise window size adjustment. The system monitors streaming parameters and performs prioritization operations based on streaming status to optimize network performance.
