WDP

Short for WAP Datagram Protocol, a network-layer protocol for delivering datagrams over a wireless IP network. Modeled after UDP, WDP provides a common interface to the upper layers of the protocol stack so that they can function independently of the wireless bearer networks (such as SMS, CDPD, and GPRS) being used by the sender and receiver of the transmissions. WDP performs three basic tasks: port addressing, segmentation of datagrams and the subsequent reassembly of the packets at the receiving end, and error reporting. Unlike other protocols, WDP does not confirm datagram delivery, resend lost packets or correct errors that occur during transmission.
