Network function virtualization using tagged access ports

A computer program product for handling virtual network traffic, the computer program product comprising:

• one or more computer-readable tangible storage devices and program instructions stored on at least one of the one or more tangible storage devices, the program instructions comprising:
• receiving a data packet by a virtual LAN (VLAN) located on a switch;
• determining a virtual device, located on a physical device, associated with the data packet;
• determining a tagged access port between the switch and the physical device, wherein the tagged access port handles all network traffic between the switch and the physical device;
• determining a VLAN-ID based on the tagged access port and the virtual device;
• and
• routing the data packet to the virtual device based on the VLAN-ID.

A computer system for handling virtual network traffic, the computer system comprising:

• one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage devices, and program instructions stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, the program instructions comprising:
• receiving a data packet by a virtual LAN (VLAN) located on a switch;
• determining a virtual device, located on a physical device, associated with the data packet;
• determining a tagged access port between the switch and the physical device, wherein the tagged access port handles all network traffic between the switch and the physical device;
• determining a VLAN-ID based on the tagged access port and the virtual device;
• and
• routing the data packet to the virtual device based on the VLAN-ID.
