TCP is responsible for providing reliable, in-sequence end-to-end delivery of data between applications. Which of the following are direct consequences of this design choice? Choose all correct answers. A. TCP can only work correctly if the layer below it also delivers data reliably and in sequence. B. TCP is self-contained with sufficient addressing information in its header that it does not need the IP layer, or any other layer beneath it to deliver data to the far end. C. TCP requires no connection state to be established prior to the end points communicating D. TCP saves an application from having to implement its owrn mechanisms to retransmit missing data, or resequence arriving data
