Answer 1

I think this is the task more of a protocol, assuming that you are the man who writes both the transmitting and receiving sides of application. For example you could implement some simple logic protocol and divide you data into packets. Then divide packets into two parts: the head and the body. And then to say that your head consists of a predefined starting sequence and contains number of bytes in the body. Of forget about starting sequence and simpy transfer number of bytes in the bofy as a first byte of the packet. Then you've could solve you problem.
