Abstract :
The end-to-end principle is fundamental to the design of the Internet, requiring that hosts participating in a transport connection remain continuously capable of processing packets. However, this principle conflicts with the energy-saving needs of battery-powered wireless devices, which benefit from short and intermittent activity periods.
In this talk, we present a QUIC connection delegation mechanism that allows a client to transfer an active connection to a trusted third party by securely migrating its connection state. The third party then maintains the connection and handles data exchanges on behalf of the original client, allowing the client device to enter a power-saving mode. Our evaluation shows that QUIC connection delegation can reduce energy consumption over Wi-Fi by up to 55% when the smartphone can utilize its sleep mode, and by 25% when accounting for background traffic and an active display.
