            QUIC-LB: Generating Routable QUIC Connection IDs
                   draft-duke-quic-load-balancers-04

Abstract

   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.
