Osi transport model
The transport layer is the layer in the open system interconnection (osi) model responsible for end-to-end communication over a network it provides logical. T common transport service models: x connectionless: datagram, no promises, error detection optional, no error recovery, no timing x connection-oriented: error . The model the [iso 8072/ad1] standard describes the osi connectionless transport services definition the [iso 8602] standard describes the osi.
