STANAG 5066 Extension Protocol Series

STANAG 5066 is a NATO Standard “PROFILE FOR HF RADIO DATA COMMUNICATIONS” providing a link level service for HF Radio. The latest version is Edition 3 of December 2010.

There are a number of issues with the current STANAG 5066 specification, particularly in relation to its use with the new Wideband HF (WBHF) specifications. NATO is aware of the need to update STANAG 5066 and has expressed intention to do so.

The S5066-EP series is intended to address the open issues prior to STANAG 5066 official update. This series of documents provides a set of extensions that can be used in conjunction with STANAG 5066 edition 3. The intent is that vendors and those procuring systems can reference these specifications, prior to this capability being available to NATO.

It is anticipated that this functionality will be folded into a future update of STANAG 5066 and at that point the series can be obsoleted.

Isode is managing the S5066-EP series as a community service. The initial S5066-EP documents are written by Isode but we encourage other individuals, organizations and vendors to contribute documents to this series.

Exchange of Information on STANAG 5066 EPs

The STANAG 5066 are all published on the Isode website.

There is an open mailing list for discussion of current and new S5066-EPs: s5066-ep (at) isode.com. To join this list or manage your subscription, please send a message to s5066-ep-request (at) isode.com.

Document Requirements

S5066-EPs must be openly available specifications that NATO may incorporate into a future edition of STANAG 5066.  They must be free of IPR or Patent restrictions that would prevent this.

These specifications are intended for implementation and must provide sufficient clear information to be implemented in context of STANAG 5066 Ed3.

S5066-EPs must have a clear publication date, and (apart from this document) a referenceable version number. S5066-EPs must have a status value which is one of:

  • Experimental: A new proposal for consideration.
  • Implemented: A specification that has at least one implementation that has demonstrated viability of the proposal.
  • Interoperable: A specification with two independent implementations that have been shown to inter-operate.
  • Informational: A document that does not have interoperability considerations.

The First in the Series: STANAG 5066 Padding DPDU

This document introduces a new STANAG 5066 DPDU to pad transmissions, which enables enhanced performance with no overhead. You can read the full extension on the Isode website.

Draft & Release for Military Messaging: An Open, Online Approach

In military communications, messages are frequently sent to organizations (e.g., a Command) rather than to an individual or to a role.

The receiving organization will process the message using a Profiler, which looks at meta-information (such as a Subject Indicator Code “SIC”) in the message in order to dispatch it to the appropriate recipient. This process of examination and dispatch is known as draft and release and is, today, mostly done using a mix of paper and online systems. A number of deployments have sought to introduce entirely online systems for draft and release but the approaches used in those deployments all have weaknesses.

In a new whitepaper on the Isode website, “Open Online Draft & Release“, Isode proposes a new open standards based approach to online draft and release, combining the best practices of existing systems with capabilities for message review which can be used independent of draft and release.

ACID Multi-Master Replication in M-Vault

In our latest release, R16.3, we added a multi-master replication capability to our M-Vault directory server, to complement the single master approach of previous releases.

A new whitepaper looks at the approach we took to support multi-master and how that approach addresses the ACID (Atomicity, Consistency, Isolation, Durability) database transaction reliability requirements.

The whitepaper then sets the approach in the context of other techniques used in distributed directories. For more information, follow the link to “ACID Multi-Master Replication in M-Vault Directory“.

New Whitepaper: Isode’s Solution for BRASS

HF Radio is an important naval communication channel for ‘beyond line of sight’ (BLOS) communication, BRASS (Broadcast and Ship to Shore) is an approach used by Navies, particularly those of NATO countries, to communicate between ships and shore using HF.

In a new whitepaper (Isode’s Solution for BRASS) we give an overview of BRASS and describe our strategy and solution for this area. The whitepaper looks at how our products can support the protocols and interoperability for currently deployed BRASS systems and move them forward to state of the art capabilities that can extend the services offered over BRASS.
