Abstract
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.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
86 words
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, and means, 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.
Claim 2
Dependent Claim
86 words
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, and means, 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.
Claim 3
Dependent Claim
28 words
The message routing system according to claim 1 wherein said means for editing comprises means for popping one of said nested multi-element address specifications off of said stack.
Claim 4
Dependent Claim
25 words
The message routing system according to claim 1 wherein said means for editing comprises means for pushing a new multi-element address specification onto said stack.
Claim 5
Dependent Claim
27 words
The message routing system according to claim 1 wherein said means for editing comprises means for altering at least one element of a nested multi-element address specification.
Claim 6
Dependent Claim
32 words
The message routing system according to claim 1 wherein said means for editing further comprises an edit table for specifying an editing action to be taken for particular nested multi-element address specifications.
Claim 7
Dependent Claim
95 words
The message routing system according to claim 1 further comprising means at each said at least one node for determining if said at least one node is the destination for a message on said networks, a destination node routing table for specifying the route to the next node in a route to a destination node for use when said at least one node is not the destination of said message, and a user specifying table for specifying a user on the current node when said at least one node is the destination of said message.
Claim 8
Dependent Claim
82 words
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.
Claim 9
Dependent Claim
82 words
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.
Claim 10
Dependent Claim
27 words
The method according to claim 7 wherein said step of editing further comprises the step of popping one of said multi-element address specifications off of said stack.
Claim 11
Dependent Claim
27 words
The message routing system according to claim 7 wherein said step of editing further comprises the step of pushing a new multi-element address specification onto said stack.
Claim 12
Dependent Claim
27 words
The method according to claim 7 wherein said step of editing further comprises the step of altering at least one element of a nested multi-element address specification.
Claim 13
Dependent Claim
33 words
The method according to claim 7, wherein said step of editing further comprises the steps of specifying, in an edit table, an editing action to be taken for particular nested multi-element address specifications.
Claim 14
Dependent Claim
94 words
The method according to claim 7 further comprising the steps of at each said at least one node, determining if said at least one node is the destination for a message on said networks, specifying, in a destination node routing table, the route to the next node in a route to a destination node for use when said at least one node is not the destination of said message, and specifying, in a user specifying table, a user on the current node when said at least one node is the destination of said message.
Claim 15
Dependent Claim
101 words
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.
Claim 16
Dependent Claim
101 words
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.
