A method and system for dynamically creating and servicing master-slave pairs within and across switch fabrics of a portable computing device (“PCD”) are described. The system and method includes receiving a client request comprising a master-slave pair and conducting a search for a slave corresponding to the master-slave pair. A route for communications within and across switch fabrics is created and that corresponds to the master-slave pair. One or more handles or arrays may be stored in a memory device that correspond to the created route. Next, bandwidth across the route may be set. After the bandwidth across the newly created route is set, the client request originating the master-slave pair may be serviced using the created route. Conducting the search for the slave may include comparing unique identifiers assigned to each slave in a master-slave hierarchy. The search within and across switch fabrics may also include reviewing a fabric route check table for slaves that can be interrogated within a switch fabric.
