It's the problem of your codec. In TCP/IP, a packet can be split into
multiple packets and multiple packets can be merged into small number
of packets. We call it 'fragmentation and assembly'. Therefore, your
codec must consider such a situation. Actually it's not really
difficult to take account into that. Please refer to our protocol
codec tutorial in the documentation page.
