Method and system for VXLAN encapsulation offload

A system for virtual extensible local area network (VXLAN) decapsulation, comprising:

• a first network device, comprising a first processor, and configured to:
• receive a VXLAN frame on a first ingress port of the first network device, wherein the VXLAN frame comprises a source VXLAN tunnel endpoint (VTEP) internet protocol (IP) address, a first destination VTEP IP address, a first VXLAN network identifier (VNI), and a first media access control (MAC) frame;
• identify a first ingress port ID (IPID) based on the source VTEP IP address;
• identify a first egress port ID (EPID) based on the first destination VTEP IP address, wherein the first destination VTEP IP address is associated with a first destination VTEP;
• determine that the first destination VTEP is located on the first network device;
• generate a first augmented MAC frame, wherein the first augmented MAC frame comprises the first IPID, the first EPID, the first VNI, and the first MAC frame;
• identify a first egress port on the first network device based on the first EPID;
• and
• send the first augmented MAC frame to a second network device via the first egress port on the first network device;
• and
• the second network device, comprising a second processor and operatively connected to the first network device, and configured to:
• receive the first augmented MAC frame on a second ingress port of the second network device, wherein the second ingress port connects to the egress port on the first network device, and wherein the first MAC frame in the first augmented MAC frame comprises, a source host MAC address and a first destination host MAC address;
• learn the source host MAC address based on the first IPID;
• and
• forward the first MAC frame to a third network device based on the first destination host MAC address.

A non-transitory computer readable medium (CRM) comprising instructions, which when executed by a processor, performs a method for virtual extensible local area network (VXLAN) decapsulation, the method comprising:

• receiving a VXLAN frame on a first ingress port of a first network device, wherein the VXLAN frame comprises a source VXLAN tunnel endpoint (VTEP) internet protocol (IP) address, a destination VTEP IP address, a VXLAN network identifier (VNI), and a media access control (MAC) frame;
• identifying an egress port ID (EPID) based on the destination VTEP IP address, wherein the destination VTEP IP address is associated with a destination VTEP;
• determining that the destination VTEP is located on the first network device;
• identifying an ingress port ID (IPID) based on the source VTEP IP address, wherein the source VTEP IP address is associated with a source VTEP;
• generating an augmented MAC frame, wherein the augmented MAC frame comprises the IPID, the EPID, the VNI, and the MAC frame, and wherein the MAC frame comprises a destination host MAC address;
• identifying an egress port on the first network device based on the EPID;
• and
• sending the augmented MAC frame to a second network device via the egress port on the first network device.
