Group First, let's look at the concept of the next grouping. The so-called grouping is to divide a packet into smaller packets. For example, for a 10GB packet, it is not always a one-time delivery of the past bar, but it is divided into a number of small packets sent past. Structure diagram for each block of data:File headers are typically descriptive data, such as source and destination addresses, data types, and so on. The data part is what is really going to be communicated to the objectCircu
