This part of IEC 62056 specifies a connection-less and a connection oriented transport layer (TL) for DLMS/COSEM communication profiles used on IP networks.
These TLs provide OSI-style services to the service user DLMS/COSEM AL. The connectionless TL is based on the Internet Standard User Datagram Protocol (UDP). The connectionoriented TL is based on the Internet Standard Transmission Control Protocol (TCP).
Annex A shows how the OSI-style TL services can be converted to and from UDP and TCP function calls.
