Re: [Ryu-devel] Switch Disconnect Event - Takes too long to detect a disconnect.

2017-11-26 Thread Iwase Yusuke
Hi Carlos, Ryu will detect the switch disconnection with sending OPFEchoRequest messages periodically, because eventlet's socket does not seem to raise the disconnection immediately (due to the non-blocking mode?). If you need to detect switch disconnection more faster, please configure the f

Re: [Ryu-devel] How to process BGP Update message in ryu application

[Ryu-devel] [PATCH] ofproto_v1_5_parser: Change default of command_bucket_id

2017-11-26 Thread IWASE Yusuke
