Interfacing with remote MXI-Express RIO chassis

Hi All,  I am writing my real time application in C on NI-9030, and I am trying to connect to an MXI-Express RIO chassis (NI 9159). If I open a session with the remote MXI chassis using the following code (which is provided in NiFpga.h):  

********************************************************************

NiFpga_Status NiFpga_Open(const char*     bitfile,                                                  

                                                 const char*     signature,                                                 

                                                 const char*     resource,                                                  

                                                 uint32_t        attribute,                                                 

                                                 NiFpga_Session* session);   

********************************************************************

Will RT controller (NI-9030) communicate with the remote chassis (NI9159) using high throughput communication protocol that NI-9159 supports, or will it be just usual Ethernet protocol? If it is just usual Ethernet protocol, is there any other C API that will support high throughput communication protocol between NI-9030 and NI-9159?

How are you planning to connect the 9030 and your MXIe chassis?
