Some of our friends from Cadmidium and Ask IT's Done Ltd visited Isode recently, bringing with them some RapidM HF Data Modems and three HF Radios for a day testing messaging and applications over HF radio.
We had a set up with three HF radios (a Yaesu FT817, a Yaesu FT847 and an Icom IC-7200) and Military Grade RM6 Modems from RapidM. We used small aerials, using very low power ground wave. Tests were done with STANAG 4539 (NAT0 3G) Waveforms mostly operating at 600 bits per second. Link level used the RapidM STANAG 5066 servers and Isode STANAG 5066 clients.
Modern military communications are a key component of Network Centric Warfare. HF Radios are used extensively for military communications, and, although very slow, provide effective long distance communication in a wide range of situations.
A new whitepaper on the Isode website looks at how HF Radio fits with Network Centric Warfare, and looks at approaches for integrating HF Radios to maximize their effectiveness.
XMPP is the eXtensible Messaging and Presence Protocol, which is the Internet Standard for Instant Messaging, Real Time Messaging and Presence. On January 16th, the sale of an XMPP client and server solution by jabber.com to the US Marines for 280,000 users was announced.
This large sale ties in with XMPP activity at lead US Military groups such as JFCOM (Joint Forces Command) and SPAWAR (Space and Naval Warfare Systems Command) (more).
XMPP is also now included in US DoD IT Standards Register as Mandatory.
There is a clear trend towards the US military broadly adopting XMPP, which will have impact on Instant Messaging choices being made by other parts of the US Government as well as military organizations worldwide. We believe that this announcement is further confirmation that Isode's own Instant Messaging product development strategy and our choice of XMPP is the right one.
Isode Partner Boldon James have announced that they've won a large Military Messaging Handling System (MMHS) contract that includes components from Isode.
Our Military Messaging components are something that we've put a lot of work into and it's nice to be able to semi-publicly acknowledge a sale in a market that is understandably reticent about releasing details of sensitive contracts. Although even with this contract we're not allowed to say which 'European Ministry of Defence' the contract is for.
The details of the contract, which is being delivered via Hewlett Packard can be found on the Boldon James website here.
Our congratulations go to Boldon James, together with our hopes for many more successes of this type.
As we approach the next major Isode release, R14, we'll be publishing whitepapers and making a series of announcements highlighting some of the benefits of that release.
Today we're publishing a new whitepaper on the Isode website "Sending FLASH Messages Quickly: Techniques for Low Latency Message Switching and Precedence Handling", which should be of particular interest to those involved with X.400 messaging.
Military Messaging systems, and other messaging systems with time critical operational requirements such as Aviation (AMHS), require that high precedence messages are submitted, transferred and delivered very quickly.
In this whitepaper we look at how messages can be handled to achieve message switching times of a few hundred milli-seconds, for both low and high volumes of traffic. The importance of Permanent Associations as a way of avoiding delays in opening a connection is described and consideration is given to Precedence Handling, describing techniques that ensure high precedence traffic gets optimum (low) latency. The paper explains why message pre-emption is not a useful approach and why DiffServ is important when there are bandwidth limitations.
The use of DiffServ to set IP packet precedence based on message precedence is one of the enhancements made to M-Switch X.400 in R14.
The whitepaper which, like all Isode whitepapers, is free and can be viewed without registration, is available here.
