9.3 BBF over IP In
This block is used when the GSE (Generic Stream Encapsulation) is done using an external
NOP1760 for very high rate satellite links.
This functional blocks takes in BBFs (Baseband Frames) over IP and indicates if they are received
correctly.
The IP packets are received on one of the two data interfaces. The incoming BBFs are monitored.
The following parameters are monitored, total BBF Input rate, the total BBF Forwarded frames
(towards the modulator) and the amount of dropped frames.
This block is also responsible for analyzing (stripping off) the IP header. The IP header contains,
next to the destination IP address (Data1/Data2 or Data Bond) also wether or not the MDM6000
belongs to a multicasts group or if it is unicast.
When the device belongs to a multicasts group, the multicasts IP Address must be entered along
with the corresponding UDP port. When both parameters are correct the BBFs are transferred
towards the modulator block.
The following figure shows how the BBF over IP block strips off of the IP header and that it is directly
mapped into BBFs.
