Two different mechanisms of NIDD (Non IP Data Delivery) are defined n the 3GPP 23.401
1) SCEF based delivery (via T6 reference point)
2) SGi PtP based (via S5/S8 reference point)
Is there any difference between this two methods regrading the amount of Data that can be exchanged to/from IoT devices?
Does SGi based allow larger amount of Data then the SCEF based delivery?
