The routing method for wireless transport service comprises a step of
receiving a unicast frame from an associated client; determining whether
a destination of the unicast frame is locally associated. A wireless node
delivers the unicast frame to a final destination if positive, otherwise,
determining whether an associated transport device of a destination can
be determined. The WITnet header is added and the associated transport
device of the destination is put in an auxiliary address field if
positive, otherwise, the next step is performed to add the WITnet header
and put an address of a default edge device in the auxiliary address
field. The next step is setting a tunnel frame flag, and then delivering
the unicast frame to a next-hop toward the auxiliary address.
