Abstract
An IP packet may include an IP header and one or more optional IP extension headers. The packet may contain non-IP protocol data in one of the IP extension headers. An application that uses non-IP protocol data may use the non-IP protocol data from the IP extension header. This allows an application designed for a non-IP protocol stack to operate on a device with an IP protocol stack with minimal modification. The non-IP protocol data may support routing options within a network or sub-network.
