Configuring Multi-Hop Messaging
Multi-hop is used by organizations that use intermediaries (MSHs in this case) for message delivery. Messages flow through a multi-hop path, a connection of public or private networks and clouds. With intermediaries responsible for routing functions, the communicating parties can ignore message destination details.
Module for AS4 supports forwarding messages using both standard and custom routing functions.
When Module for AS4 acts as the sender or receiver endpoint, a TPA is required. When the module acts as an intermediary, a TPA is not required. Multi-hop configuration at the intermediary involves configuring a routing function only.
