[ndnSIM] CCN Segmentation

[Saeid Montazeri]

Hi Wali,

I have a little bit experience in ndnSIM.

Alex please correct me if I am wrong.

You can have a content with several packets by setting MaxSeq attribute of
CcnxAppHelper class.
For example I have added the bold line bellow to the code in ndn-grid.cc.
By the line, I asked CcnxAllHelper to generate Interest for 250 Data
packets of the content with name "/prefix". ("/prefix/0", "/prefix/1", ..
"/prefix/249")

std::string prefix = "/prefix";

CcnxAppHelper consumerHelper ("ns3::CcnxConsumerCbr");
consumerHelper.SetPrefix (prefix);
consumerHelper.SetAttribute ("Frequency", StringValue ("10")); // 10
interests a second
*consumerHelper.SetAttribute ("MaxSeq", StringValue("250")); *


Best Regards,
Saeid
