ZYTRAX specializes in IP Network solutions - including VoIP, Wireless LAN technology, Bandwidth Management and QoS (Quality of Service). If it's complicated and hard and has a strong communications or networking component then we're interested, have probably done it before and can probably help you. You can contact us in a variety of ways.
ZYTRAX Training specializes in Knowledge Acquisition and Transfer. We provide high quality courses in DNS, LDAP and Telecommunications where our subject-matter experts are unique in their fields. We've even written books on this stuff. We don't simply teach courses, which is what most of our competition does, we transfer the knowledge of our subject-matter experts to our students. Our experts are passionate about their subjects. And yes, it is possible for (relatively) normal human beings to get passionate about DNS, or LDAP or even SS7! There is a big difference being taught by someone who feels strongly about their subject. At the end of a course our students don't just know the material, they understand it. Your organization wins all round. We provide a range of standard public and on-site courses and can customize material to meet your needs.
Development and Consulting Services
We provide specialized development and consulting services to clients where we believe our in-depth IP network skills, our extensive code libraries and our FreeBSD, Linux and embedded system expertise will let us do an outstanding, but cost-effective, job.

Zytrax Tech Stuff
The ZYTRAX Tech Info section is a collection of technical information that we have found useful over the years and which is provided as a service to the community.
Zytrax Open source
ZYTRAX has been an advocate of Open Source solutions for many years, the Open Pages is a collection of material which may help others to understand its applicability in various sectors. We have also launched the second in a series of whimsically named Rocket Scientist GuidesLDAP for Rocket Scientists. The first in the series,DNS for Rocket Scientists has already proven immensely popular and is being hit over 200,000 times per month and still growing fast.
Router Products - Wireless
Our current development is a range of secure wireless routers being marketed under our Steam Packet Radio brand. The Air-Frame range of secure wireless IP products is optimised for IP network access and specifically targeted at ISPs and rural network providers. Air-Frame is designed to be rugged and reliable in typical multi-cell urban operation with an 'out-of-box' performance of 2km+ but with the power (our 'sweet spot' is 3 - 8 km) to handle outlying connections. The feature set for this class of equipment is outstanding - IPSec, DHCP Server, NAT, PAT, Firewall, Daisy-chaining and much, much more.
You may find some of these things interesting..or then again you may not...
To improve our service we are now hosted by super.net.sg. They provide a great service and are into all kinds of neat VOIP stuff. Thanks.

Open Source - it's complicated
Great software. Legal and free. OpenOffice has moved to the Apache foundation where they are figuring out how to move it forward. In the meantime we, like many others, have moved to LibreOffice. But it's all so serious now. We remember when Ethereal's (now wireshark) marketing slogan was "Sniffing the glue that holds the Internet together". Now that was fun. But fun is soooo last century.
There was a time when we got excited about HTML and CSS standards. Validated everything that moved. Religiously. But the world was young then and we believed what the W3C told us. HTML 4 was dead, XHTML was the way forward. Then came the great HTML 5 betrayal. Suddenly all that carefully crafted stuff preparing for the bright, shiny future became illegal in the validation tools. So now we are walking backward into the bright, shiny future. Meh.
