I think that OpenFlow and Ryu does not have the ability to get the available bandwidth directly.
It might this value can be calculated by using the mechanism of OpenFlow specification.

range of "weight" is uint16_t (0 ~ 65535).
"weight" of the details are described in "7.3.4.2 Modify Group Entry Message" of OFspec1.3.4.
