IANA is the international organization that oversees the assignment of IP addresses; DNS root zone management, and other Internet protocol assignments. IANA is operated by the Internet Corporation for Assigned Names and Numbers (ICANN) based in the United States whose responsibility is to oversee the administration and standards used within the Internet.

So what does this mean to you?

The registration of PVX Plus CS is official recognition of the existence of the protocols used for communication between the client and host processes of the PxPlus Client Server. More importantly to you, the dealer, is that port 4093 is now officially recognized for use by the PxPlus Client Server protocol and, as such, should not be used by any other application.

Historically, port 10000 has been used as the default port for NThost, PVX Plus Simple CS, and the Application Servers. Unfortunately, this port is registered for use by the Network Data Management Protocol and used by the Veritas backup software. This lead to potential conflicts with these IANA registered protocols.

By having PVX Plus CS assigned a registered port number, the chance of conflicts is greatly reduced. This not only will help with systems configurations, but will also provide a greater degree of interoperability with other applications on the host system.

This port number will soon be rolled out by various manufacturers into the standard port assignment list found on most Unix / Linux systems making the PxPlus Client Server port number an integral part of the respective OS environment.

Over the next few months, PxPlus will move towards standardizing on this new default port number and away from using port 10000. We will try, wherever possible, to make this transition effortless to you, your application logic, and your clients.

PVX Plus Technologies wishes to thank IANA for accepting its registration of the protocol and providing us this opportunity to serve our clients better.
