Port Rotary Group


I have an issue like this:

I use a 2511 Access Servers to aggregate 16 Serial-enabled devices. Idea is to carry Serial Device communication from an Async Line, through a TCP session in a particular port, up to a Processing Server.

My problem is that I don’t have that number of TCP ports available in Processing Server as I do have Async Lines in 2511. In other hand not all Serial Devices needs to connect in same time. Let's say for 16 Async Lines there will be enough to have about four ports (1/4 ratio).

Processing Server does not allow more that one session in particular port. When that port is occupied by one TCP session, no other session can be established from other port in that port. Also, for each port to serve PS has to have a separtate software driver. When number of this drivers increases the server becomes quite unstable.

I am aware that Rotary Groups can be applied to solve problems, opposite of this, were many TCP (telnet) session will be queued to access limited number of Async Lines. Can this or similar technique used to solve issue link one I have presented?




Re: Port Rotary Group

I think as you suggested, we can use rotary group to solve this limitation.
