The new transport protocol QUIC supports connection migration and support for multipath extension is also in under standardization. However, currently discussed QUIC multipath extension does not include a mechanism for each application to select which of the possible paths to use. Even when an application is using multiple paths for a connection, it is not possible for the application to use a different path for each stream, taking into account the characteristics of each path and the requirements of each stream. In this paper, we have considered the need for path selection in multipath-aware transport protocols with mobile devices such as smartphones that have asymmetric upstream connections, Wi-Fi and mobile connections, and based on this, we have we propose a mechanism that determines which paths to include in QUIC connections based on policy for each process, and a mechanism that groups paths included in QUIC connections based on policy and specifies which group to use for each stream or flow of datagrams in QUIC data transmission for applications using QUIC. By incorporating the mechanism into our IP VPN over QUIC system, applications that do not support QUIC can benefit from resiliency and efficiency of QUIC multipath extension and policy-based path selection. to assign voice connections and video connections or screen sharing to different paths. Its DSCP support also allows common real-time applications such as Zoom and WebEX to assign voice connections and video connections or screen sharing to different paths depending on the characteristics of each path like metered or unmetered.
