Abstract

A system of remote objects with network streaming ability includes a streaming client, a plurality of streaming servers, a streaming buffer area, a plurality of first continuous buffer areas, a streaming controller, a plurality of first network connections, and a plurality of second network connections. The plurality of streaming servers is used to respond a remote procedure call from the streaming client. The streaming buffer area stores a complete data unit for the streaming client to access. A generation method of remote objects with network streaming ability is further provided. The method includes executing a link procedure, executing a streaming preparation, executing a streaming transfer procedure, and closing the link procedure.

Claims

1. A generation method of remote objects with network streaming ability, comprising the steps of:

executing a link procedure, comprising the steps of;

establishing a plurality of corresponding first network connections between a streaming client and a plurality of streaming servers according to a remote procedure call from the streaming client; and

establishing a streaming controller by using the streaming client, wherein the streaming controller controls the transfer of a plurality of data units with a streaming object data type;

executing a streaming preparation, comprising the steps of;

collecting streaming source information from the streaming servers; and

establishing a streaming schedule according to the streaming source information, wherein the streaming schedule is associated with a plurality of available streaming servers;

executing a streaming transfer procedure to provide a complete data unit for the streaming client to access, wherein the complete data unit is associated with the data unit with the streaming object data type; and

closing the link procedure.

2. The generation method of remote objects with network streaming ability of claim 1, wherein the step of executing the link procedure further comprises:

obtaining a plurality of corresponding addresses of the streaming servers and that of the streaming client; and

providing the data unit with the streaming object data type from the streaming servers.

3. The generation method of remote objects with network streaming ability of claim 1, wherein the step of executing the link procedure further comprises:

registering each of the data units with the streaming object data type and treating each of the data units as a remote component; and

waiting for the remote procedure call.

4. The generation method of remote objects with network streaming ability of claim 1, wherein the first network connections are used to transfer the plurality of data units with the streaming object data type only.

5. The generation method of remote objects with network streaming ability of claim 1, wherein the step of executing the streaming preparation further comprises:

analyzing the remote procedure call by using the streaming controller;

performing an aggregation sort according to the streaming source information, wherein the aggregation sort is used to determine the available streaming servers; and

forming the streaming schedule according to the available streaming servers.

6. The generation method of remote objects with network streaming ability of claim 5, wherein the aggregation sort comprises the steps of:

calculating a weight for each of the streaming servers, wherein the weight is associated with a bandwidth, streaming data integrity, and an overhead of the corresponding streaming server; and

determining priorities of the available streaming servers according to their weight.

7. The generation method of remote objects with network streaming ability of claim 1, wherein the step of executing the streaming transfer comprises:

establishing a first continuous buffer area for each of the available streaming servers according to the streaming schedule so as to receive the corresponding data unit with the streaming object data type;

establishing a second continuous buffer area to form a pair of buffer areas with the first continuous buffer area; and

transferring the data units with the streaming object data type from the available streaming servers to a streaming buffer area so as to form the complete data unit.

8. The generation method of remote objects with network streaming ability of claim 7, wherein the data unit with the streaming object data type is transferred through the pair of buffer areas.

9. The generation method of remote objects with network streaming ability of claim 7, wherein the second continuous buffer area is at the streaming client.

10. The generation method of remote objects with network streaming ability of claim 7, wherein each of the first network connections is established between the corresponding pair of buffer areas.

11. The generation method of remote objects with network streaming ability of claim 1, further comprising a step of establishing a plurality of second network connections, wherein the second network connections are used to transfer control messages only.

12. The generation method of remote objects with network streaming ability of claim 1, wherein the generation method is applied in one of Java RMI and .NET Remoting.

13. A system of remote objects with network streaming ability, comprising:

a streaming client;

a plurality of streaming servers responding a remote procedure call from the streaming client;

a streaming buffer area storing a complete data unit for the streaming client to access;

a plurality of first continuous buffer areas receiving a plurality of data units with a streaming object data type from the streaming servers, wherein the complete data unit is associated with the data units with the streaming object data type;

a streaming controller determining a plurality of available streaming servers among the streaming servers;

a plurality of first network connections established between the streaming client and the available streaming servers and used to transfer the data unit with the streaming object data type only; and

a plurality of second network connections established between the streaming client and the available streaming servers and used to exchange control messages only.

14. The system of remote objects with network streaming ability of claim 13, wherein the complete data unit is formed by the streaming controller.

15. The system of remote objects with network streaming ability of claim 13, further comprising a plurality of second continuous buffer areas connected to the first continuous buffer areas through the first network connections.

16. The system of remote objects with network streaming ability of claim 13, wherein the complete data unit is formed by the data units with the streaming object data type from the available streaming servers.

17. The system of remote objects with network streaming ability of claim 13, further comprising a plurality of client remote objects and a plurality of server remote objects.

18. The system of remote objects with network streaming ability of claim 17, wherein the second network connections are connected between the client remote objects and the server remote objects.

19. The system of remote objects with network streaming ability of claim 13, wherein the system is applied in one of Java RMI and .NET Remoting.

20. The system of remote objects with network streaming ability of claim 13, wherein the available streaming servers are associated with a bandwidth, streaming data integrity, and an overhead of each of the streaming servers.
