Moreover, clients may be resource-limited, behind a low bandwidth or a long-RTT network and may need adaptations to improve data transmission or reception. While each client and server can have its dedicated solution to store path parameters, having a standard way of exchanging this information helps in providing symmetrical control of the optimisation and reducing protocol ossification. QUIC may not be limited to HTTP3: it can be used as a substrate for proxying and tunneling. This memo discusses a solution where the client is informed about path parameters: both the client and the server can contribute to the reduction of the time-to-service for subsequent connections. This would improve symmetrical transmission of data and reduce ossification of the protocol. To improve the time-to-service of subsequent 0-RTT reconnection the server currently sets in the early\_data extension the maximum volume of egress data the client is allowed to send when reconnecting. This memo proposes BDP\_metadata, an additional extension, to also inform the client about path parameters.}, }
