}
Expand description

This message protocol contains header and body, and the header includes checksum, datalen,respectively, u32, u32, where datalen represents the length of the body, checksum is used to check the datalen field. This is just the most basic pedestal protocol, in order to solve the sticky packet problem with TCP streams. We can build more advanced communication on top of this protocol, for example, we can use json or other forms of data representation
