You can also see from the length of these fields in the header that TCP adds a lot of network overhead. Application developers may choose to save overhead for the sake of efficiency, while sacrificing some reliability, by using another protocol in the transport layer, UDP.User Datagram ProtocolWhen comparing User Datagram Protocol (UDP) to TCP, UDP is essentially a small-scale economic model, sometimes referred to as a thin protocol. Like a thin person sitting on a park bench, thin protocols don't take up much space-or in this case, I should say, too much network bandwidth.UDP doesn't offer as many fancy features as TCP, but it can provide reliable transmission for those who don't needapplications, providing perfect transport services, and it will only consume very few network resources (the UDP protocol is defined in RFC 768).In many cases, it is a wise decision for program developers to choose to use UDP, rather than TCP. One such case is where the program/application layer already provides reliability features. The Network File System (NFS), for example, is responsible for its own reliability issues, making it impractical and unnecessary to use TCP to provide reliability. Ultimately, however, it is up to the application developer to decide whether to use UDP or TCP, not the user who wants to transfer data faster.
