Abstract: Methods and systems for performing a Mapping of Address and Port using translation (MAP-T) data plane verification. A method for performing a MAP-T data plane verification includes initiating, by a diagnostic server provisioned with at least MAP-T diagnostic rules, a MAP-T diagnostic on a border relay provisioned with MAP-T rules, generating, by the diagnostic server, a diagnostic packet per the MAP-T diagnostic rules, sending, by the diagnostic server, the diagnostic packet to the border relay, performing, by the border relay, a translation on the diagnostic packet per the provisioned MAP-T rules, analyzing, by the diagnostic server to generate a report, at least a translation accuracy of a received translated diagnostic packet, and configuring at least one device based on a received report.

Abstract: Methods and systems for an accelerated and offload dual border relay. A method includes receiving, by a hardware border relay from a network device, an Internet Protocol (IP) packet, determining, by the hardware border relay, a packet type of the IP packet, translating, by the hardware border relay provisioned with IPv6 transition technology rules, the IP packet to a hardware translated IP packet when the IP packet is a first type, translating, by the offload border relay provisioned with MAP-T rules, the IP packet to an offload translated IP packet when the IP packet is a second type, transmitting, by the offload border relay to the hardware border relay, the offload translated IP packet when the IP packet is the second type, and transmitting, by the hardware border relay, one of the offload translated IP packet and the hardware translated IP packet to another network device.
