Virtual network function enabled secure communication systems and methods

A method for enabling secure communication comprising:

• providing a first virtual network function (“VNF”) on a first edge cloud at a first network location;
• providing a second VNF on a second edge cloud at a second network location;
• constructing a first Layer 3 virtual private network (“L3 VPN”) tunnel by the first VNF and the second VNF between the first network location and the second network location;
• connecting a first local area network (“LAN”) at the first network location and a second LAN at the second network location by the first L3 VPN tunnel;
• transmitting via the first L3 VPN tunnel via Multi-Protocol Label Switching (“MPLS”) a first plurality of Layer 2 (“L2”) packets encapsulated by first outer headers and first provider labels;
• providing a third VNF on a third edge cloud at a third network location;
• constructing a second L3 VPN tunnel by the first VNF and the third VNF between the first network location and the third network location;
• transmitting via the second L3 VPN tunnel via MPLS a second plurality of L2 packets encapsulated by second outer headers and second provider labels;
• constructing a third L3 VPN tunnel by the second VNF and the third VNF between the second network location and the third network location;
• and
• transmitting via the third L3 VPN tunnel via MPLS a third plurality of L2 packets encapsulated by third outer headers and third provider labels.
