Deciding which communication type to use

There are four types of communication for MQI channels on different platforms:

• LU 6.2

• NetBIOS

• SPX

• TCP/IP

When you define your MQI channels, each channel definition must specify a transmission protocol (transport type) attribute. A server is not restricted to one protocol, so different channel definitions can specify different protocols. For WebSphere MQ clients, it might be useful to have alternative MQI channels using different transmission protocols.

Your choice of transmission protocol also depends on your particular combination of WebSphere MQ client and server platforms. The possible combinations are shown in the following table.

Table 11. Transmission protocols - combination of WebSphere MQ client and server platforms

Transmission protocol	WebSphere MQ client	WebSphere MQ server
TCP/IP	UNIX systems Windows	i5/OS UNIX systems Windows z/OS
LU 6.2	UNIX systems1 Windows	i5/OS UNIX systems1 Windows z/OS
NetBIOS	Windows	Windows
SPX	Windows	Windows
Notes: Except Linux (POWER platform)

Defining a connection is described in the following sections:

• Defining a TCP/IP connection

• Defining an LU 6.2 connection

• Defining a NetBIOS connection

• Defining an SPX connection
