Interior Server and Gateway Server Architecture

TIBCO BusinessConnect Interior Server is the server on which TIBCO BusinessConnect is installed ontop of the other required TIBCO software products: TIBCO Runtime Agent, and TIBCO Administrator.For a list of all required TIBCO and other third party software products, see TIBCO BusinessConnect

Installation and Configuration, Installation Requirements.

A diagram of the Gateway Server and Interior Server communications is depicted in Figure 4.

Figure 4 Gateway and Interior Server Communication

TIBCO BusinessConnect Interior Server

This server is located inside the companys firewall and performs the following tasks:

Handles all messaging level activities, such as encryption, decryption, and digital signatures.

Takes care of business level logic to be executed by an individual protocol, such as documentschema validation.

TIBCO BusinessConnect Gateway Server

TIBCO BusinessConnect Gateway Server is located in the demilitarized zone (DMZ) and can haveseveral restrictions on the networks it can access. It receives B2B communications directly from the

Internet and performs SSL validation. The firewall between the Gateway Server and the rest of yoursystem protects against the threat of malicious communications.

TIBCO BusinessConnect Gateway Server is a standalone Java executable that is not dependenteither on TIBCO ActiveMatrix BusinessWorks or on TIBCO Runtime Agent installation however, it stillneeds TIBCO Rendezvous to communicate with the Interior server. The Gateway Server can hostseveral components:

HTTP Server

PartnerExpress Server This server provides a secure web-based access for trading partners, sothat the external users associated with these trading partners can log in and perform simple file

uploads and downloads.

FTP Server With this server, the external users running an FTP Client can connect to the hostsite running TIBCO BusinessConnect.

TCM Server TCM server provides a web browser interface for trading partners to manage theirexchange profiles, and assists the trading host in serving the partners in the trading community. Allservices are provided through a browser-based interface that allows partners to receive alerts,

SSHFTP Server With this server, the external users running an SSHFTP Client can connect tothe host site running TIBCO BusinessConnect.

Interior and Gateway Server Communication

Two types of communication are used between the Gateway and Interior Servers: JMX and TIBCORendezvous.

JMX Communication

Management of the Gateway Server is performed using JMX management protocol. Using TIBCOAdministrator, you can remotely control which component to start or stop.

When an empty Gateway Server container is started, it first publishes a message with informationabout its management and data ports. The Interior Server is listening on the same subject, subscribesitself, and then the JMX communication/data communication for large files is established. JMXcommunication is also used between the TIBCO Administrator GUI and the Interior Server as follows:

From the TIBCO Administrator GUI To start and stop the service instances or event sources,such as HTTP, FILE, SSHFTP, FTPS, FTP, TCM, and PX.

From the Interior Server To auto-restart the event sources in an active Service Instance tomonitor the heartbeat of the Gateway Server.

TIBCO Rendezvous Communication

The Gateway Server and Interior Server communicate via TIBCO Rendezvous.
