Hi,
Thank you for yor kindly reply.
I know that OpenFlow 1.1 spec add group type which support multipath or
multicast.
However, OpenFlow 1.0 is in the most switches and environment. It is
easy to implent multicast in OpenFlow 1.0, but how could I implement
multipath using flow table entries in OpenFlow 1.0?
