Allocation of I/O Data

Example
I/O Size, Interface A = 30 bytes
I/O Size, Interface B = 20 bytes
Transport Provider I/O Size = 20 bytes - 10 bytes = 10 bytes
Fig. 14 Transport Provider example
If the Transport Provider shall handle the complete I/O image towards the other network, the I/O
size should be set to 0 (zero) on the Ethernet interface.
