Abstract:
A communication apparatus stores topology information that is shared by communication apparatuses included in a network and representing connection states between the communication apparatuses. The topology information includes port identification information for identifying ports that are connectable to each other within each communication apparatus. The communication apparatus determines a route by sequentially selecting a port that can be connected to a port, to which transmission data is input based on the port identification information.
