Overview of the TCP/IP Palette

The TCP/IP palette provides activities and resources that can send and receive data using the TCP/IP protocol. TCP/IP is often the underlying communication layer for higher-level protocols such as HTTP or FTP. You could use the resources in the TCP palette to communicate with HTTP or FTP severs, but the activities in the HTTP Palette or FTP Palette are best suited for this purpose. This palette is intended for use when communicating with TCP/IP and there is no corresponding TIBCO ActiveMatrix BusinessWorks palette for the protocol. For example, you may have a custom application that communicates with other applications by way of TCP/IP. You could use the TCP/IP palette to handle incoming and outgoing data from this application.

Using the TCP/IP Palette Activities

The general sequence of events when using the TCP/IP palette resources is the following:

1.	Create a TCP Connection shared configuration resource that describes the connection information.

2.	One of the following occurs depending upon whether the process definition is a TCP/IP client or server:

a.	When a process definition acts as a TCP/IP client communicating with a TCP/IP server, a connection must be opened using the TCP Open Connection activity.

b.	When a process definition acts as a TCP/IP server waiting for incoming TCP/IP requests, the process either starts with a TCP Receiver process starter or has a Wait for TCP Request activity that waits for an incoming connection request.

3.	In the process definition the Read TCP Data and Write TCP Data activities are used to read and write data to the TCP connection.

4.	Once all processing is complete, the TCP Close Connection activity is used to close the TCP connection.
