LTM Mutliplexing

I don't know if this is possible, but I need to make one TCP connection to each node, but allow many other tcp connections to be terminated on the LTM. Our application connects to a payment proces...

You may be in luck... Or not... Too many unknowns to be sure...

 

The feature you're after is one-connect... But in order for it to multiplex correctly, I think it'll have to be HTTP traffic (Otherwise PTM won't know hoe to multiplex the request/response traffic to serialise it).

 

If it is HTTP, then configure the cone-connect with a mask of 0.0.0.0 (Means any client IP will match an existing server side connection and re-use it) and set the max connections of the node to 1 (So you don't get a second connection created).

 

Now.. I'm not 100% sure what will happen if the server-side connection is busy... (Sorry, not tried that scenario).

 

However even if those assumptions fail, as long as YOU can code in an iRule to differentiate between the request/response, then you could accept the request in the iRule, and process it yourself. Possibly with a sideband connection.
