Conversations

This section applies to LU 6.2 only.

Once a session is established between two LUs, the LU-LU session supports the exchange of information between two TPs, which have the exclusive use of the session to execute a transaction. This exchange of information is called a conversation. Only one conversation can use a particular session at a time, but sessions are serially reusable (many conversations can use the same session, one after another).

To initiate a conversation, a source TP sends a request to its LU, asking it to allocate a conversation with a remote TP. The invoking TP (or source TP) initiates the conversation, like the calling party in a telephone conversation. The invokable TP or target TP (the remote TP) is the partner in the conversation, like the party who receives a telephone call.
