Re: [pcp] TR: I-D Action: draft-vinapamula-flow-ha-05.txt

["Prashanth Patil (praspati)" <[e-mail]>]

My concern with the proposal is that that an application will always
choose to checkpoint its flows. Why would an application ever consider
otherwise i.e. consider its flow not critical?
The draft suggests "Administration SHOULD restrict the number of
connections that can be elected to be backed up and the rate of
check-pointing on per PCP client.", which doesn¹t really address the above
problem.
