[ndnSIM] Data Packet Payload

[Spyridon (Spyros) Mastorakis]

Hello Marco,

The payload of a Data packet is actually a NS-3 packet instance, which is included inside another NS-3 packet instance (i.e., the Data packet as a whole). In essence, you have a NS-3 packet instance inside another NS-3 packet instance. 

The most straightforward way that I can think right now is to convert the NS-3 packet to the corresponding Data packet and then use the GetPayload () method that returns a pointer to the NS-3 packet that contains the payload. Of course you can iterate over a buffer, but I really think that this is an extremely low level operation..

Hope that this helps.

Otherwise, is it possible to read it by using the iterators provided in the Buffer class? Specifically i’d need to read the payload as a string.
