List<LinkEdge>	getRoute(InventoryReader rdr, SalNode src, SalNode dst) Return the packet route from the source to the destination switch.

Method Detail

getRoute

List<LinkEdge> getRoute(InventoryReader rdr,
                        SalNode src,
                        SalNode dst)

Return the packet route from the source to the destination switch.

Parameters:

rdr - A InventoryReader instance which contains active read transaction for the MD-SAL datastore.

src - A SalNode instance corresponding to the source switch.

dst - A SalNode instance corresponding to the destination switch.

Returns:

A list of LinkEdge instances which represents the packet route. An empty list is returned if the destination node is the same as the source. null is returned if no route was found.

getPathPolicyId

int getPathPolicyId()

Return the identifier of the path policy associated with this route resolver.

Returns:

The identifier of the path policy.
