41. Examples of connectionless protocols are Ethernet, Internet Protocol ( IP ), and the User Datagram Protocol ( UDP ). 42. The vast bulk of Internet traffic is Transmission Control Protocol ( TCP ) or User Datagram Protocol ( UDP ) packets. 43. The Stream Control Transmission Protocol ( SCTP ) and the Datagram Congestion Control Protocol ( DCCP ) also use port numbers. 44. Except for some initialization dialogue that requires stronger synchronization, FICON uses Fibre Channel class of service 3 ( Datagram ). 45. There is a " datagram mode " in which ST packets can be encapsulated over IP headers using protocol number 5. 46. According to Jason Jones, the network code is DDP, or Datagram Delivery Protocol to transfer information between each machine. 47. The field size sets a theoretical limit of 65, 527 bytes for the data carried by a single UDP datagram . 48. UDP provides checksums for data integrity, and port numbers for addressing different functions at the source and destination of the datagram . 49. For a brief period, the specification also included a connectionless datagram service, but this was dropped in the next revision. 50. The Time Protocol may be implemented over the Transmission Control Protocol ( TCP ) or the User Datagram Protocol ( UDP ).
