|   The interaction is more complex.
|   
|   For example, if the current path fails, it is detected by the
|   transport/applicaiton layer. Thus, it is necessary for the
|   transport/application layer tell the network layer use an 
|   alternative
|   locator.
|   
|   Later, as the original path may be resumed, it is also necessary
|   for the transport/application layer tell the network layer try an
|   old locator. Note that there may be several old locators.
|   
|   To do so, transport/application layer and network layer must have
|   common identification mechanism of locators.
|   
|   It is much easier for the transport/applicaiton layer to handle
|   locators directly. Then, all the information necessary for
|   transport/application layer control is included in the IP header.


All of this could be handled by a set of opaque handles to locators,
without the direct interaction of the transport layer and the 
locators.
