However, Simply sending the messages in bursts does not guarantee that the messages will be received in order. For example if I send 3 messages in 3 bursts I receive messages like this below ex) send (3 burst) [1111111] [22222] [33333] ex) recv [33333] [22222] [1111111] So In order to solve this issue, I was struggling with reorder library and ip fragmentation in l3fwd example. Which library do I have to use in order to achieve the result like this below? (IP fragmentation or Reorder Library) ex) send (3 burst) [1111111] [22222] [33333] ex) recv [1111111] [22222] [33333]
