C# single client that connects to several server

Question

I have to design a tcp-ip application based on a single client that open several connections against external server. Obviously I thought to open a different socket for each server (max 12) and use an asynchronous connection, because those server may send me data on every moments. Someone could point me to a efficient pattern in order to create this kind of client?

thanks

Have a look on Observer and/or Visitor.
