[Ace-users] pattern for server manager

[Saya]

Hi all,

I am trying to build a server manager which will manage its ports, so
that at any time the server manger could create, enable or disable a
port or ports. Basically the server should be capable of allowing a
single client to connect to one of its port, so for example,
application A wil connect on port 2000
application B will connect on port 3000

and so forth, at any time the admin should be able to add a new port
4000 (or what ever ) and allow another application to connect on it.

I will like to know what is the most efficient way of building this
because I am just a starter with ACE and might end up using the wrong
pattern/s, any how what I tried now, is by using the reactor pattern
and I ran into problems with regard to dynamically adding ports
(probably because I used the object in the wrong way), I would like to
know if the reactor is already a singleton or if i would have to take
any special measures to make it explictly a singleton?

Should I use some other pattern for this?

What pattern should I use to have seperate threads created for each
port? Will it be possible to achieve seperate threads for seperate
ports using the reactor?

thank you in advance for your advices,

regards,

Sayanthan
