A logical partition can use virtual Ethernet to establish multiple high speed inter-partition connections.
Logical partition software allows you to configure up to 16 different virtual local area networks. Virtual Ethernet provides the same function as using a 1 gigabyte (GB) Ethernet adapter. i5/OS® and Linux partitions can communicate with each other using TCP/IP over the virtual Ethernet communication ports.
