Hi,
Yes, you are right.
But, there seems to have been a little misunderstanding.
On Ryu-Book, the tree dots("...") means that some messages or words are just
omitted.
e.g.)
If the full messages are:
---
connected socket:<eventlet.greenio.base.GreenSocket object at
0x7fab639f1610> address:('127.0.0.1', 32776)
hello ev <ryu.controller.ofp_event.EventOFPHello object at 0x7fab639eb810>
move onto config mode
EVENT ofp_event->SimpleSwitch13 EventOFPSwitchFeatures
switch features ev
version=0x4,msg_type=0x6,msg_len=0x20,xid=0xcd66c812,OFPSwitchFeatures(auxiliary_id=0,capabilities=79,datapath_id=1,n_buffers=256,n_tables=254)
move onto main mode
---
Ryu-Book omits some messages or words like:
---
connected socket:<... # omitting "eventlet.greenio.base.GreenSocket ..."
hello ev ... # omitting "<ryu.controller.ofp_event.EventOFPHello object at
0x7fab639eb810>"
... # omitting some messages
move onto main mode
---
Therefore, you can get correct messages from ryu-manager described in Ryu-Book.
Thanks,
Iwase

What NetFlow Analyzer can do for you? Monitors network bandwidth and traffic
patterns at an interface-level. Reveals which users, apps, and protocols are
consuming the most bandwidth. Provides multi-vendor support for NetFlow,
J-Flow, sFlow and other flows. Make informed decisions using capacity planning
reports.http://sdm.link/zohodev2dev
