Abstract

In order to generate high bandwidth traffic in a digital communication network that uses direct addressing message distribution, the present message traffic generation system uses existing external signaling drivers to initiate stimulus message traffic over low speed links. In the present message traffic generation system, a low bandwidth message generator is used in combination with reciprocating message distribution methods to generate high bandwidth stimulus message traffic and thereby verify the high bandwidth utilization of the high bandwidth transport mediums and the switching system nodes they interconnect.

Claims

1. A message traffic generation system, operable in a digital communication network that comprises a plurality of nodes, interconnected by high bandwidth signaling links, for propagating stimulus messages throughout said digital communication network, comprising:

message driver means for transmitting at least one stimulus message to at least one originating node of said plurality of nodes via associated signaling links;

message propagation means, located in said at least one originating node and responsive to the receipt of said stimulus message, for transmitting said stimulus message to at least one destination one of said plurality of nodes via associated signaling links; and

message echo means, located in said at least one destination node and responsive to receipt of said stimulus message, for returning said stimulus message to said at least one originating node.

2. The message traffic generation system of claim 1 wherein said message driver means comprises:

node address means for identifying a single node address in said stimulus message as said destination node.

3. The message traffic generation system of claim 2 wherein said message propagation means comprises:

retransmission means for transmitting said stimulus message a predetermined plurality of times to said destination node via associated signaling links.

4. The message traffic generation system of claim 1 wherein said message driver means comprises:

node address means for identifying a node address list in said stimulus message that identifies said destination nodes.

5. The message traffic generation system of claim 4 wherein said message propagation means comprises:

retransmission means for transmitting said stimulus message a predetermined plurality of times to at least one destination one of said plurality of nodes via associated signaling links.

6. The message traffic generation system of claim 1 wherein said message echo means comprises:

burst means, responsive to receipt of said stimulus message, for generating a burst of said stimulus messages for return said at least one originating node.

7. The message traffic generation system of claim 1 wherein said message echo means comprises:

burst means, responsive to receipt of said stimulus message, for generating a burst of said stimulus messages for return at least one identified node.

8. The message traffic generation system of claim 1 further comprising:

bounce node means, responsive to receipt of said stimulus message, for forwarding said received stimulus message to at least one other one of said plurality of nodes via associated signaling links.

9. The message traffic generation system of claim 8 wherein said bounce node means comprises:

retransmission means for transmitting said stimulus message a predetermined plurality of times to at least one destination one of said plurality of nodes via associated signaling links.

10. The message traffic generation system of claim 8 wherein said bounce node means comprises:

burst means, responsive to receipt of said stimulus message, for generating a burst of said stimulus messages for return at least one identified node.

11. A method of operating a message traffic generation system, operable in a digital communication network that comprises a plurality of nodes, interconnected by high bandwidth signaling links, for propagating stimulus messages throughout said digital communication network, comprising:

transmitting at least one stimulus message to at least one originating node of said plurality of nodes via associated signaling links;

forwarding, from said at least one originating node in response to the receipt of said stimulus message, said stimulus message to at least one destination one of said plurality of nodes via associated signaling links; and

returning, from said at least one destination node in response to receipt of said stimulus message, said stimulus message to said at least one originating node.

12. The method of operating a message traffic generation system of claim 11 wherein said step of transmitting comprises:

identifying a single node address in said stimulus message as said destination node.

13. The method of operating a message traffic generation system of claim 12 wherein said step of forwarding comprises:

retransmitting said stimulus message a predetermined plurality of times to said destination node via associated signaling links.

14. The method of operating a message traffic generation system of claim 11 wherein said step of transmitting comprises:

node address means for identifying a node address list in said stimulus message that identifies said destination nodes.

15. The method of operating a message traffic generation system of claim 14 wherein said step of forwarding comprises:

retransmitting said stimulus message a predetermined plurality of times to at least one destination one of said plurality of nodes via associated signaling links.

16. The method of operating a message traffic generation system of claim 11 wherein said step of returning comprises:

generating, in response to receipt of said stimulus message, a burst of said stimulus messages for return said at least one originating node.

17. The method of operating a message traffic generation system of claim 11 wherein said step of returning comprises:

generating, in response to receipt of said stimulus message, a burst of said stimulus messages for return at least one identified node.

18. The method of operating a message traffic generation system of claim 11 further comprising:

forwarding, in response to receipt of said stimulus message, said received stimulus message to at least one other one of said plurality of nodes via associated signaling links.

19. The method of operating a message traffic generation system of claim 18 wherein said step of returning comprises:

retransmitting said stimulus message a predetermined plurality of times to at least one destination one of said plurality of nodes via associated signaling links.

20. The method of operating a message traffic generation system of claim 18 wherein said step of returning comprises:

generating, in response to receipt of said stimulus message, a burst of said stimulus messages for return at least one identified node.
