Experience has shown that extension of protocols without early IETF review can carry risk. The document also recommends that major extensions to or variations of IETF protocols only take place through normal IETF processes or in coordination with the IETF. This document is directed principally at other Standards Development Organizations (SDOs) and vendors considering requirements for extensions to IETF protocols. It does not modify formal IETF processes. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.}, }
