Transaction message routing in digital communication networks
First Claim
1. A user-invokable message routing system for packet communications networks for routing messages across said networks from an originating station on one of said networks to a destination station on one of said networks, said routing system comprisingmeans for defining origin and destination addresses with a user-specified stack of nested multi-element address specifications, andmeans, at at least one intermediate node in said networks, for editing said user-specified stack of said nested multi-element address specifications to dynamically modify any one element of said multi-element address specifications.

Abstract
Packet messages transmitted on a packet communications network include origin and destination addresses in the form of stacked address elements which can be pushed or popped off of the stack. A plurality of interconnected packet communications network include routing nodes which utilize the top address element on the destination stack to route the message. Such routing nodes also include stack element editing facilities for popping elements from the stocks, constructing new elements to be pushed onto the stacks, and amending the contents of elements on the stack. This arrangement allows messages to be launched on the networks where the originating station does not have full knowledge of the destination station, and the routing nodes add the necessary destination information as it becomes necessary for routing.

7. A user-invoked method for routing messages through packet communications networks from an originating station on one of said networks to a destination station on one of said networks, said method comprising the steps of
defining origin and destination addresses with a user-specified stack of nested multi-element address specifications, and editing, at at least one intermediate node in said networks, said said user-specified stack of said nested multi-element address specifications in order to dynamically modify any one element of said multi-element address specifications.

13. A user-invokable message routing system for packet communications networks for routing messages across said networks from an originating station on one of said networks to a destination station on one of said networks, said routing system comprising:
-
means for defining origin and destination addresses with a user-specified stack of nested multi-element address specifications, wherein at least one of said nested multi-element address specifications in said user-specified stack includes a user-specified parameter element; and means, at at least one intermediate node in said networks, for editing said user-specified stack of said nested multi-element address specifications based on said user specified parameter element.
