Multipath TCP (MPTCP) adds the capability of using multiple paths to
a regular TCP session.  Even though it is designed to be totally
backward compatible to applications, the data transport differs
compared to regular TCP, and there are several additional degrees of
freedom that applications may wish to exploit.  This document
summarizes the impact that MPTCP may have on applications, such as
changes in performance.  Furthermore, it discusses compatibility
issues of MPTCP in combination with non-MPTCP-aware applications.
Finally, the document describes a basic application interface that is
a simple extension of TCP's interface for MPTCP-aware applications.

This document is a product of the Multipath TCP Working Group of the IETF.
