Scalable Reliable Datagram (SRD) transport provides reliable
out-of-order delivery, transparently utilizing multiple network paths to
reduce network tail latency.
Its interface is similar to UD, in particular it supports message size
up to MTU, with error handling extended to support reliable
communication.
