This article will explain in detail the meaning of Datagram, data packet and grouping in big data. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Packet capture concept: Datagram, packet, packet

1. Datagram: when the application builds the data to be sent according to the protocol format. The data at this time is called Datagram, or Datagram for short. The characteristic is that the data has not been sent yet.

two。 Packet: when the Datagram is sent, it will be processed according to the requirements of the network, such as IP slicing and TCP slicing. The data at this time is the data actually sent, which is called the packet.

3. Grouping: it is proprietary to Wireshark. When Wireshark catches the actual transmitted data packet, it will perform additional processing, such as reassembling the shard packet and displaying the reorganized data in the last shard packet. So the packet at this time is not necessarily the data actually transmitted.
