21. TACLANEs provide encryption for IP datagram traffic. 22. Protocols such as User Datagram Protocol ( UDP ) provide no recovery for lost packets. 23. The DHCP employs a connectionless service model, using the User Datagram Protocol ( UDP ). 24. Generally, where TCP is unsuitable, the User Datagram Protocol ( UDP ) is used. 25. Datagram service is therefore considered connectionless.26. Recently, SCTP is finding applications beyond its original purpose wherever reliable datagram service is desired. 27. The sending of broadcast packets, a datagram socket should be bound to the wildcard address. 28. It also defines addressing methods that are used to label the datagram with source and destination information. 29. The most common transport layer protocol to use multicast addressing is User Datagram Protocol ( UDP ). 30. AX . 25 supports both virtual-circuit connected and datagram -style connectionless modes of operation.
