Dear Sir,
Thanks for your help.
I am still confused by the "message propagation".
In the following figure,
X publisher --- A router ----.....---M router--....------B router----Y Subscriber.
I also think the message published by X will be stored in A. What make me confused is
"progation of message from A router to B router".
According to what you say: "In an messaging model no message is duplicated or delivered
more that once. And also no message is stored more than once.", I think the message itself published
by X will never reach the intermediate routers such as M and B routers. And Y retrieve its
messages directly from the ROUTER A. Otherwise, if the message itself will be routed along some routes,
this message must be duplicated in some intermediate router. Am I right?
If what I think above is right (the published messages itself will never be routed), then the routing functions
in the SwiftMQ is used to for what? Is the routing function (such as DV or Dijkstra algo) used to
route the SwiftMQ internal information rather the message itself published by publishers. Isn't it?
Sorry for so many problems!
Thanks very much!
