Oracle Solaris 11.2 supports virtual extensible local area networks (VXLANs), providing increased flexibility and isolation in cloud environments where virtualization causes an increased stress on physical network infrastructure. VXLANs decouple virtual networks from the underlying L2 layer, reducing the need for specific physical switching capabilities. While traditional network isolation methods such as virtual local area network (VLAN) can have a maximum of 4000 isolated networks, VXLAN provides a significantly higher number of isolated networks by using a 24-bit VXLAN identifier, thereby providing an option to support 16 million isolated networks.
