Freefloat started last year to develop a proxy platform for terminal emulator solutions using telnet protocol. We thought that using standardized Split-TCP technology was a good idea.

It wasn't.

During initial testing we found that only 80-90% of the scenarios worked as predicted. We wanted a solution that could handle 100% of the cases when networks and connections fail.

The solution is now here!

Freefloat proudly presents Proxy*One - the most stable proxy platform on the market. Click for more information.

A proxy server works in between a client and a host. The purpose is to secure and maintain connections regardless of the network access status of the client. The proxy server is installed within the wired network with high bandwidth access to the host. From there it can serve clients on WLAN, WAN as well as wired networks with wireless links on the way.

Are WLANs stable today?

Well, most WLANs are very stable as long as the client is not moving too fast. But when you introduce roaming clients, both within WLAN coverage area (moving between Access Points) and when moving in and out of coverage area (real roaming) you are almost guaranteed to have problems with unwanted disconnects. The cure for this is to add a proxy architecture.

Freefloat Proxy Server works like a standard proxy server but Freefloat has added a few but very important innovations to the concept:

• All traffic from the client to the proxy is tunnelled in UDP packets. UDP has a great advantage over TCP. The packets are sent connectionless, therefore they are not sensitive to disconnects. The proxy server makes sure that all packets are forwarded to the client/host correctly. If the connection goes down the proxy will keep trying until the network is up again and the operator will be able to keep working like if nothing happened.
• All problems are logged in detail for each client. This log file can be used to identify clients with problems, like bad antennas etc.
• All connections are kept alive. Regardless of the wireless link’s stability communication between the client and host continues uninterrupted. No need to re-login, unlock session or clean up half-ready transactions.
Summary
By adding Freefloat Proxy Server not only do you raise the availability of your network by reducing disconnects, but you are also making the work more efficient. On top of that it will save time and money every day because helpdesk can focus on more important issues than unlocking sessions, workers don’t have to wait for re-connects and the customers will receive their orders faster. Freefloat Proxy Server can be added to any TCP/IP based solution but it offers the greatest benefits in terminal emulator environments. If used in combination with Freefloat’s terminal emulator Access*One you can enjoy even more functionality, like auto-configuration etc.
