Mllp Protocol
What is MLLP and how does it work
MLLP wraps HL7 messages in three framing bytes and sends them over TCP. How the protocol works, why healthcare still uses it, and what to know before implementing it.
MLLP framing bytes: 0x0B, 0x1C, 0x0D
MLLP uses three bytes to frame HL7 messages over TCP. How start block, end block, and carriage return work together, and the edge cases that break implementations.
