Pavani,
Can you please clarify if you are looking for required and provided ports or interfaces ?
We already have support for interfaces. Component has a number of provided and required Interfaces, that form the basis for wiring components together.
An InterfaceRealization link can be created between a Component and an Interface : we say that the Component has a provided Interface.
A Usage link can be created between a Component and an Interface : we say that the Component has a required Interface.
If this is not what you are looking for, then please elaborate and if possible attach a screenshot to help us get a visual.
