NATO STANAG 5518 PDF

AIM

1. The aim of this agreement is to register acceptance to adopt the USA MILSTD- 3011, titled "Interoperability Standard for Joint Range Extension Application Protocol" as a NATO interoperability standard.

2. This STANAG acts as a covering document for a United States Military Standard, USA-MIL-STD-3011, dated 30 September 2002, in its entirety, and adopts that USA standard as a NATO standard.

3. Participating nations agree to use MIL-STD-3011 for the definition of the protocols and message structures for the transmission and reception of preformatted messages over communications media other than those for which these messages were designed. It provides a foundation for Joint Range Extension (JRE) of Link 16 and other tactical data links (TDLs) to overcome the line-of-sight (LOS) limitations of radio terminals, such as Joint Tactical Information Distribution System (JTIDS) and Multifunctional Information Distribution System (MIDS).

4. The Joint Range Extension Application Protocol (JREAP) is based upon the Open System Interconnection (OSI) layered structure and focuses on the application layer; however, it recognizes that certain network and transmission layer services provided by JTIDS and MIDS terminals for Link 16 are not provided by all communications media. The JREAP also provides for these services, where needed.

5. The main body of the standard describes the common message structures, message elements (data fields), and protocols primarily at the application level that are independent of the media. Appendices are provided for specific communication modes to describe necessary JREAP message and protocol modifications and provide the OSI layer services appropriate for each mode.

6. Currently, the standard addresses the following communication modes:

a. Half-Duplex Announced Token Passing.

b. Full-Duplex Synchronous and Asynchronous Point-to-Point.

c. Internet Protocol (IP) (User Datagram Protocol (UDP) Unicast and Multicast, and Transmission Control Protocol (TCP)).

7. Changes to MIL-STD-3011 will be agreed or accepted in accordance with the methods of work of the USA's configuration management authorities responsible for MIL-STD-3011. Configuration management and configuration control over MILSTD- 3011 will remain solely with the USA, with ratification of the STANAG by other nations indicating only that they agree to adopt this national standard as a NATO standard for those purposes, and only those purposes, mentioned within the STANAG.
