6. The communication processing device of claim 1 , wherein when a respective band of the bandwidth that is allocated and used by a respective one of the communication units is less than a lower bandwidth usage limit thereof, and when there is some remaining portion of the bandwidth before the lower bandwidth usage limit is reached, any of the communication units having lower priority are not allocated with the remaining portion of the bandwidth.
7. A communication processing method comprising:
storing a policy table having a plurality of entries, where each entry associates: (i) a communication unit identifier that identifies one of a plurality of communication units of a communication device, each of the plurality of communication units employing one of a plurality of communication protocols; (ii) a policy identifier, which defines an upper bandwidth usage limit and a lower bandwidth usage limit within which the given communication unit should operate; and (iii) a priority indicator, which defines priorities among the plurality of communication units as to usage of a communication network over which the communication processing device communicates data;
