QUIC-LB: Generating Routable QUIC Connection IDs
Martin Duke, Nick Banks · 2019
QUIC connection IDs allow continuation of connections across address/ port 4-tuple changes, and can store routing information for stateless or low-state load balancers. They also can prevent linkability of connections across deliberate address migration through the use of protected communications between client and server. This creates issues for load-balancing intermediaries. This specification standardizes methods for encoding routing information and proposes an optional protocol called QUIC-LB to exchange the parameters of that encoding. This framework also enables offload of other QUIC functions to trusted intermediaries, given the explicit cooperation of the QUIC server.
