3.2.2.5.1 REQUEST

A REQUEST packet MUST have auth_type equal to zero, and its interface ID MUST match the conversation manager interface as specified in [C706] Appendix P. The packet's Header.Flags.frag bit MUST be zero. Otherwise, the packet MUST be discarded.

If the packet is accepted, it is processed as specified in [C706] Appendix P. Implementations of this protocol SHOULD serialize execution of conversation manager callback calls.
