Hl7 Transport Methods 1

What Are Common HL7 Transport Methods?

This section describes the most common HL7 transport method used to send HL7 messages, called the Lower Layer Protocol (LLP). A less common HL7 transport called the Hybrid Lower Layer Protocol (HLLP) is also briefly discussed. Although HL7 messages are sent via a variety of TCP/IP transports, including FTP, SOAP and SMTP, LLP is the most common method.
