I don't even understand what was built in emacs. A "message router"? Its job was to take messages in from a set of links and transfer them out some other set of links? How did it know what links led where, or how to make progress towards the final hop? How was the path computed? If TCP/IP was already available as a layer, why not just use its routing capabilities? What was DCE and how did it help?
- p_l 2y agoTCP/IP only understands routing along IP addresses. "Message router" usually involves understanding higher level entities - In this case, it would understand that a given type of message with given information needs to be forwarded to X, Y, and Z. DCE was "Distributed Computing Environment", and provided among other things RPC system that is still used by MS Windows NT and DCOM. In this case it was easier to make all parts of the system first talk TCP/IP, then use DCE to provide glue code between divergent environments.
