-Virtual Ethernet Port Aggregator (VEPA) - This is an IEEE EVB term. A VEPA multiplexes the traffic of one or more VSIs onto a single Fortville Ethernet port. The biggest difference between a VEB and a VEPA is that a VEB can switch packets internally between VSIs, whereas a VEPA cannot.

-My understanding of VEB is that it's an in-NIC switch(MAC/VLAN), and it can support VF->VF, PF->VF, VF->PF packet forwarding according to the NIC internal switch. It's similar as Niantic's SRIOV switch.
-
-Floating VEB Introduction
-=========================
-
-Floating VEB is based on VEB Switching. It will address 2 problems:
-
-Dependency on PF: When the physical port is link down, the functionality of the VEB/VEPA will not work normally. Even only data forwarding between the VF is required, one PF port will be wasted to create the related VEB.
-
-Ensure all the traffic from VF can only forwarding within the VFs connect to the floating VEB, cannot forward out of the NIC port.
