(1) What type of RFC is being requested (BCP, Proposed Standard, Internet Standard, Informational, Experimental, or Historic)? Why is this the proper type of RFC? Is this type of RFC indicated in the title page header?
This document is being requested for publication as an experimental RFC. The document describes a multi-path approach to time distribution protocols. The experiment will allow verification of the effectiveness of the proposed method. The intended status is shown on the title page.
(2) The IESG approval announcement includes a Document Announcement Write-Up. Please provide such a Document Announcement Write-Up. Recent examples can be found in the "Action" announcements for approved documents. The approval announcement contains the following sections:
The Network Time Protocol (NTP) and the Precision Time Protocol (PTP) are the two most common protocols for time and frequency distribution over packet-based networks. This document describes a multi-path approach to NTP and PTP over IP networks, allowing the protocols to run concurrently over multiple communication paths between the master and slave clocks. The multi-path approach can significantly contribute to clock accuracy, security and fault tolerance.

(15) Are there downward normative references (see RFC 3967)? If so, list these downward references to support the Area Director in the Last Call procedure.
There is a normative reference to an external document, the IEEE 1588 standard which defines the Precision Time Protocol (PTP).
