Abstract

Communication occurs between a source and a destination over plural communications paths by first identifying content to be sent to a destination via a communications system. After discovering that plural communications paths connecting directly to the destination are available, the content is divided into plural different portions and is transmitted to the destination such that each of the plural different portions is routed via a different one of the plural communications paths.

Claims

1. A system for communicating between a source and a destination over plural communications paths, said system comprising:

a source connected to a first communications system; and

a destination connected to a second communications system, wherein;

(a) the source identifies content to be sent to the destination;

(b) the source discovers that plural direct communications paths to the destination are available, each said direct communications path having a different network address associated with the destination;

(c) the source divides the content into plural different portions;

(d) the source transmits the content to the destination by sending at least some of the plural different portions to different ones of the network addresses; and

(e) the destination receives the plural different portions and aggregates them into an original composition,

wherein each of the plural direct communications paths to the destination is a link between a last router on a corresponding network and the destination.

2. A system according to claim 1, wherein step (b) comprises receipt by the source of a message via an electronic communications system that the plural direct communications paths are available.

3. A system according to claim 2, wherein the message also indicates a capacity for at least one of the plural direct communications paths.

4. A system according to claim 3, wherein the content is divided in step (c) based on the capacity indicated in the message.

5. A system according to claim 3, wherein the message also includes pricing information for at least one of the plural direct communications paths.

6. A system according to claim 3, wherein the source also receives a second message updating the capacity indicated in the message.

7. A system according to claim 1, wherein at least one of the first and second communications systems comprises an Internet.

8. A system according to claim 1, wherein the source at least one of:

(i) receives a message indicating a format for dividing the content, (ii) transmits a message to the destination indicating a format for dividing the content, and (iii) retrieves a format for dividing the content that has been pre-arranged with the destination.

9. A system according to claim 2, wherein the message is received from the destination.

10. A method for communicating between a source and a destination over plural communications paths, said method comprising:

(a) identifying content to be sent to a destination via at least one electronic network;

(b) discovering that the destination has associated with it plural different destination network addresses, each said destination network address corresponding to a different direct communications path to the destination;

(c) dividing the content into plural different portions; and

(d) transmitting the content to the destination such that the plural different portions are routed via different ones of the plural direct communications paths, by addressing at least some of the plural different portions with the different destination network addresses,

wherein each of the plural direct communications paths to the destination is a link between a last router on a corresponding network and the destination.

11. A method according to claim 10, wherein the different destination network addresses have been provided by the destination.

12. A computer-readable storage medium storing computer-executable process steps for communicating between a source and a destination over plural communications paths, said process steps comprising steps to:

(a) cause the source to identify content to be sent to the destination;

(b) cause the source to discover that plural direct communications paths to the destination are available, each said direct communications path having a different network address associated with the destination;

(c) cause the source to divide the content into plural different portions;

(d) cause the source to transmit the content to the destination by sending at least some of the plural different portions to different ones of the network addresses; and

(e) cause the destination to receive the plural different portions and to aggregate them into an original composition,

wherein each of the plural direct communications paths to the destination is a link between a last router on a corresponding network and the destination.

13. A computer-readable medium according to claim 12, wherein step (b) comprises receipt by the source of a message via an electronic communications system that the plural direct communications paths are available.

14. A computer-readable medium according to claim 13, wherein the message also indicates a capacity for at least one of the plural direct communications paths.

15. A computer-readable medium according to claim 14, wherein the content is divided in step (c) based on the capacity indicated in the message.

16. A computer-readable medium according to claim 14, wherein the message also includes pricing information for at least one of the plural direct communications paths.

17. A computer-readable medium according to claim 14, wherein said process steps further comprise a step to cause the source also to receive a second message updating the capacity indicated in the message.

18. A computer-readable medium according to claim 12, wherein the at least one of the different network addresses comprises an Internet address.

19. A computer-readable medium according to claim 12, wherein said process steps further comprise a process step to cause the source to at least one of:

(i) receive a message indicating a format for dividing the content, (ii) transmit a message to the destination indicating a format for dividing the content, and (iii) retrieve a format for dividing the content that has been pre-arranged with the destination.

20. A computer-readable medium according to claim 13, wherein the message is received from the destination.
