Abstract:
This document specifies a solution to discover the capabilities of a
flow-aware service function. The solution relies upon the use of the
Port Control Protocol (PCP).
This solution allows for applications to anticipate connectivity
failures and to proceed with countermeasures (e.g., create a mapping
for incoming connections, discover a mapping lifetime, discover an
external IP address, avoid injecting some options in the outgoing
packets, etc.). The propsoed approach allows, for example, to
discover whether an upstream flow-aware service function is MPTCP-
friendly (that is, it does not strip MPTCP signals) or SCTP-
compliant, whether it embeds a firewall function, etc. or a
combination thereof.
