The Routing Slip combines the central control of the super-router approach (Option E) with the efficiency of the hard-wired solution (Option C). We determine the complete routing scheme up front and attach it to the message, so we do not have to return to the central router for further decision making. Each component is augmented by simple routing logic. In the proposed solution, we assume that this routing logic is built into the processing component itself. If we look back at Option A, we remember that we dismissed this approach partly because we had to hard-code some logic into each component. How is the Routing Slip better? The key difference is that the router used in the Routing Sl...
