18.6 Protocol Stack
The following figure represents the wire protocol dependencies of the Transaction Processing Services protocols. For instance, the Transaction Manager to Transaction Manager communication specified in the Transaction Internet Protocol (TIP) Extensions, is performed over TCP.
Figure 138: Transaction Processing Services Protocol stack
All communication with Transaction Managers via the protocols specified by the MSDTC Connection Manager: OleTx Transaction Protocol, MSDTC Connection Manager: OleTx Transaction Internet Protocol, and MSDTC Connection Manager: OleTx Transaction Protocol Logical Unit Mainframe Extension depend upon the protocol specified by the MSDTC Connection Manager: OleTx Multiplexing Protocol, which in turn depends on the protocol specified by the MSDTC Connection Manager: OleTx Transports Protocol, which depends on RPC.
The Subscribe for Transaction Information action of the Management Tool is performed by the protocol specified by the MSDTC Connection Manager: OleTx Management Protocol using the protocol specified by the MSDTC Connection Manager: OleTx Multiplexing Protocol. The Configure Settings action is performed through the use of the protocols specified by the Windows Remote Registry Protocol and the Service Control Manager Remote Protocol.
