TCP vs UDP

UDP can also be used in noisy environments; however the transmission control protocol that manages packet loss, sequencing, etc. must be higher in the protocol stack.

TCP does the 'transmission reliability' transparent to the application programmer. However, this does not preclude the use of higher level 'transmission reliability' on top of UDP systems.

In fact, I have worked with many companies who had issues with the overhead associated with TCP and rebuilt the transmission control model on top of UDP or RAW SOCKETS.

TCP is designed for a generic Internet end-to-end model; however it is not perfect or the most efficient for all transmission models. It is inaccurate to translate 'connectionless' UDP vs. 'connection oriented' TCP to 'unrealiable' and 'reliable'. TCP is connection oriented. UDP is not connection oriented. UDP can be used in applications where connection oriented behavior is required, it just must be done in a higher level in the stack.

We would have to start a new forum 'Advanced UNIX' or 'Advanced Networking' to further discuss, as this is not a newbies topic.
