3.2. Introduction: Basic Networking Terms

Red Hat Virtualization provides networking functionality between virtual machines, virtualization hosts, and wider networks using:

  • A Network Interface Controller (NIC)
  • A Bridge
  • A Bond
  • A Virtual NIC
  • A Virtual LAN (VLAN)

NICs, bridges, and VNICs allow for network communication between hosts, virtual machines, local area networks, and the Internet. Bonds and VLANs are optionally implemented to enhance security, fault tolerance, and network capacity.
