why the downchannel should send directives interface every seconds

[kangshifu]

in your project,we send directives interface to amazon serve evert seconds,when we catch IOException,we send the serve request immediately in Downchannel.java

Yes, I thought if the call to enqueue fails then rather than starting again I should make the call again to that method and send the request again to amazon server. Is this what you are asking?
