Hi everybody, I met a question about RYU topology discovery, I use RYU 3.24 to connect 81 ovs vswitches, and each ovs vswitch is connect to each other----it's my test bed, I wrote my route method to avoid link-loops,
But when I start my ryu controller to connect the 81 ovs-swicthes simultaneously, the RYU report such an error "broken pipe", at last my ryu controller will exit.... Error info as below, can anybody help me or know something to improve the performance of ryu? Thank you very much~ ---------------------------------------------------------------------------------------------------------------------------------------------------------------------- hub: uncaught exception: Traceback (most recent call last): File "/usr/local/python/lib/python2.7/site-packages/ryu/lib/hub.py", line 52, in _launch func(*args, **kwargs) File "/usr/local/python/lib/python2.7/site-packages/ryu/controller/controller.py", line 102, in deactivate method(self) File "/usr/local/python/lib/python2.7/site-packages/ryu/controller/controller.py", line 187, in _send_loop self.socket.sendall(buf) File "/usr/local/python/lib/python2.7/site-packages/ryu/controller/eventlet-0.10.0-py2.7.egg/eventlet/greenioio.py", line 287, in sendall tail = self.send(data, flags) File "/usr/local/python/lib/python2.7/site-packages/ryu/controller/eventlet-0.10.0-py2.7.egg/eventlet/greenioio.py", line 273, in send total_sent += fd.send(data[total_sent:], flags) error: [Errno 32] Broken pipe ----------------------------------------------------------------------------------------------------------------------------------------------------------------------
