- Can anyone point me to a commercially-available solution to this
- problem?
-
- We are designing an application which will run on multiple Unix
- systems & be accessible via TCP/IP. We would like to make these
- systems available to users on the Internet using a single IP
- address. Since the "application systems" all run pretty much
- independently of each other, we envision something like this:
-
- Internet
- |
- [ Front ]
- [ End ]
- |
- ---------------------------------
- | | |
- [ Appl ] [ Appl ] [ Appl ] ...
- [ Host ] [ Host ] [ Host ]
- [ # 1 ] [ # 2 ] [ # 3 ]
-
- The Front End system would listen for connections on a given
- port using sockets (say it's the Telnet port), accept them,
- open a new connection to the same port on whichever Appl Host
- was the least loaded at the same port (connecting to the
- real Telnet server when it gets there) and then pass data
- back and forth between the Telnet client out in the Internet
- and the Telnet servers on the Appl Hosts.
-
- This would be a relatively easy piece of code to write, but
- I am concerned about the performance of the Front End system
- (i.e., I don't want it to become a bottleneck).
-
- Does anyone know of an off-the-shelf system we could use in the
- place of the Front End? I was hoping for something, perhaps from
- one of the router vendors, that would be designed and fine-tuned
- for this purpose & thus support a high number of simultaneous
- connections.
-
- Any pointers you can give would be greatly appreciated.

- Thanks, Robin Hermance-Moore (rhm@oclc.org)
