Abstract
Some embodiments of the invention provide a novel method of tunneling data packets. The method establishes a tunnel between a first forwarding element and a second forwarding element. For each data packet directed to the second forwarding element from the first forwarding element, the method encapsulates the data packet with a header that includes a tunnel option. The method then sends the data packet from the first forwarding element to the second forwarding element through the established tunnel. In some embodiments, the data packet is encapsulated using a protocol that is adapted to change with different control plane implementations and the implementations' varying needs for metadata.
