Explanation of these codes

[Ayman M Alrehaili]

Hi group members 

  Can anyone explain  in detal the flowing codes on ns-3 

static const uint32_t totalTxBytes = 10000000;

static const uint32_t sendBufSize  = 14000; 

static const uint32_t recvBufSize  = 2000; 

static uint32_t currentTxBytes     = 0;

static const double simDuration    = 360000000.0;

and how I can Know the type of the traffci which using in any simulation code

Hi Ayman,

Your first question shows that your programming skills are close to zero.

I would recommend to study a good C++ primer to get some basic knowledge.

To answer your question, these are just variables defined for your scenario. 

They do not mean anything without any context, i.e. how/where you use it.

The names may be representative of their use, for example totalTxBytes would be expected to be used as a control on how many bytes you want to transmit. 

But without the context on where it is used, that is just a speculation. 

That's because I have seen people naming one variable "X" and assigning to a context "Y".

Your second question is even more cryptic. What do you mean with traffic used in simulation code?
