<DIV dir=ltr>Hi John:<BR> <BR>I am working on a project with similarities to wackamole (a distributed resources allocation algorithm).<BR> <BR></DIV>
<DIV dir=ltr>>> Or are you just marking messages so that they can be easily ignored if they are delivered in a different view than the one in which the client thought they were sent?<BR></DIV>
<DIV dir=ltr>PAP: Yes, I am interesting to know the view version to discard messages outside the current view.</DIV>
<DIV dir=ltr> </DIV>
<DIV dir=ltr> </DIV>
<DIV dir=ltr>>>However, in EVS (Spread) semantics, message delivery and view changes occur asynchronously. That is, there is little ordering dependence between them. A message is not necessarily ordered and delivered in the view in which the client *thinks* it is sending. Several views might be installed between the time a client sends a message and it gets to delivered in EVS.</DIV>

<DIV dir=ltr>But, what about.</DIV>

<P dir=ltr>message delivery? I think that they will be synchornized with view change messages ? </P>
<DIV dir=ltr> </DIV>
<DIV dir=ltr>>>> then you may want to look into the flush layer of Spread that provides exactly such a service.</DIV>
<DIV dir=ltr>PAP: I don't understand this statement. Can you explain me about it?</DIV>

<DIV dir=ltr>Thanks John.</DIV>
