<P><FONT SIZE=2 FACE="Arial">Which execution domain is best suited to modeling the interactions between n clients and a service which will also be receiving simultaneous updates of its stored information ?</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Please let me elaborate just a bit more on this scenario:</FONT>
<BR><FONT SIZE=2 FACE="Arial">A service exists - presumably a web service or web application - which will be receving updates of some status information but these updates will be on an irregular (indeterminate) basis. Simultaneously and also on an irregular basis, some number of clients will be contacting this service and requesting this information from the service.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">I have downloaded the complete PtolemyII and Kepler sources and compiled them, and have run all the ptolemy and kepler demos in all the various execution domains. The most interesting of these (for my purposes) appears to be the PN process network domain and the CI component interaction domain. However, only the CI domain appears to allow a push model of update of actors, and this, coupled with a stack - or in the case of the Router.xml model - a linked-list (used as a FIFO) appear to be applicable to my needs. </FONT></P>
<P><FONT SIZE=2 FACE="Arial">But I am interested in any opinions on this subject that may enlighten me and disabuse of my ignorance of model behavior and applicability to the above problem. </FONT></P>
<P><FONT SIZE=2 FACE="Arial">Thanks </FONT>
