The JSON-RPC interface is for doing switch-level configuration, such as that 
provided by ovs-vsctl.  If you're looking to do flow-level configuration, which 
is what ovs-ofctl does, then you need to use the OpenFlow protocol.

Hi,
     I am looking for a way to control distributed vswitches from a centralized 
server. Although tools like ovs-ofctl could talk to remote vswitch through TCP, 
it is not a nice way to do every configuration by calling a script in my code.
     I knew vswitch uses json-rpc, and also noticed below thread:

     
http://openvswitch.org/pipermail/discuss_openvswitch.org/2009-November/000461.html
     and a page:
      http://openflowswitch.org/wk/index.php/Config_Protocol

     unfortunately, most of links in above wiki are non-valid.
     Is there any documentation defined json-rpc methods exposed by vswitch? or 
any example educates people how to talk with vswitch by json-rpc?

     thank you.
