Which communication type to use

Different platforms support different communication protocols. Your choice of transmission protocol depends on your combination of IBM® MQ MQI client and server platforms.

Types of transmission protocol for MQI channels

Depending on your client and server platforms, there are up to four types of transmission protocol for MQI channels:

TCP/IP
LU 6.2
NetBIOS
SPX

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 IBM MQ MQI 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 IBM MQ client and server platforms. The possible combinations are shown in the following table.

Table 1. Transmission protocols - combination of IBM MQ MQI client and server platforms
Transmission protocol	IBM MQ MQI client	IBM MQ server
TCP/IP	IBM i UNIX Windows	IBM i UNIX Windows z/OS®
LU 6.2	UNIX ¹ Windows	IBM i UNIX ¹ Windows z/OS
NetBIOS	Windows	Windows
SPX	Windows	Windows

Except Linux ( POWER platform)
