NETIUCV connections are only supported for compatibility with earlier versions. Do not use for new network setups.

The Inter-User Communication Vehicle (IUCV) is a z/VM® communication facility that enables a program running in one z/VM guest to communicate with another z/VM guest, or with a control program, or even with itself.

The NETIUCV device driver is a network device driver, that uses IUCV to connect instances of Linux® on z/VM, or to connect an instance of Linux on z/VM to another z/VM guest such as a TCP/IP service machine.

Features

The NETIUCV device driver supports the following functions:

  • Multiple output paths from Linux on z/VM
  • Multiple input paths to Linux on z/VM
  • Multiple paths between Linux on z/VM and the same peer z/VM guest
  • Simultaneous transmission and reception of multiple messages on the same or different paths
  • Network connections via a TCP/IP service machine gateway
  • Internet Protocol, version 4 (IPv4) only
