   Using the BEA Tuxedo TOP END Domain Gateway

The basic architecture of a BEA TOP END system is shown in the following figure.

As shown in the figure, a BEA TOP END system consists of one or more nodes. A basic node consists of a client, a node manager, and a server.

• A node may have one or more BEA TOP END systems.

• Each BEA TOP END system on a node has one node manager component.

An Application Component consists of the following:

• Application (AP)

• Resource Manager (RM)

• Transaction Manager (TM)

• Client/Server Interaction API (CSI)

The network interface (NI) is an optional component in a BEA TOP END system. An NI is not required for single-node systems. The Network Interface:

• Enables internode communication between components

• Provides optional internode message security through Kerberos routines
