Abstract
In some examples, an example method to provide a virtualized Carrier-grade Network Address Translation (CGN) at a first customer edge router may include establishing a tunnel between the first customer edge router and each aggregation router among one or more aggregation routers, performing a Network Address Translation (NAT) on a first data packet to create a NAT'ed first data packet, selecting a first aggregation router from amongst the one or more aggregation routers to send the NAT'ed first data packet to, encapsulating the NAT'ed first data packet with overlay information corresponding to a tunnel established between the first customer edge router and a first aggregation router, and sending the encapsulated NAT'ed first data packet through the tunnel to the first aggregation router.
