Abstract

A method and an apparatus for realizing web service. An apparatus having a binary web service interface to communicate with nodes operationally connected to the apparatus using a binary web service, the nodes having one or more resources, the binary web service interface being configured to receive information from a node whenever a resource of a node changes or whenever a pre-configured event regarding a resource occurs. The apparatus also has an interface for communicating with web applications making use of the resources and ap component for receiving subscriptions regarding the information received from the nodes and providing the subscribed information.

Claims

1. An apparatus, comprising:

a binary web service interface to communicate with nodes operationally connected to the apparatus using a binary web service, the nodes comprising one or more resources, the binary web service interface being configured to receive information from a node whenever a resource of a node changes or whenever a pre-configured event regarding a resource occurs;

an interface for communicating with web applications making use of the resources; and

a component for receiving subscriptions regarding the information received from the nodes and providing the subscribed information.

2. The apparatus of claim 1, wherein the apparatus is configured to request a node to send a notification whenever a given resource of the node changes.

3. The apparatus of claim 2, wherein the apparatus is configured to send a notification request to a node after receiving a subscription regarding the resource.

4. The apparatus of claim 1, further comprising:

a resource directory to store property information and address of the nodes; and

a resource cache for storing information received from the resource nodes.

5. The apparatus of claim 1, wherein the apparatus is configured to receive from a node a registration comprising information on the address and the resources of the node, and information on which resources have pre-configured events and which may be subscribed.

6. The apparatus of claim 1, wherein the apparatus is configured to receive from a web application a request to create a name to a pre-configured event and a subscription to the event.

7. The apparatus of claim 2, wherein the apparatus is further configured to aggregate several subscriptions of a same resource received from web applications to a single notification request.

8. The apparatus of claim 2, wherein the apparatus is further configured to send a node a batch notification request regarding more than one resource of the node.

9. The apparatus of claim 1, wherein the apparatus is configured to receive requests regarding a resource of a node, and on the basis of the number of requests send the node a request to send a notification whenever the resource of the node changes.

10. An apparatus, comprising:

a first binary web service interface to communicate with nodes operationally connected to the apparatus using a binary web service, the nodes comprising one or more resources, the binary web service interface being configured to receive information from a node whenever a resource of a node changes or whenever a pre-configured event regarding a resource occurs;

a second binary web service interface for communicating with a server; and

a component for receiving subscriptions from the server regarding the information received from the nodes and providing the subscribed information.

11. The apparatus of claim 10, wherein the apparatus is configured to request a node to send a notification whenever a given resource of the node changes.

12. The apparatus of claim 11, wherein the apparatus is further configured to aggregate several subscriptions of a same resource received from more than one server to a single notification request.

13. A web service system, comprising:

one or more nodes, each node comprising one or more resources operationally connected to the node; and

an first apparatus comprising;

a binary web service interface to communicate with nodes operationally connected to the apparatus using a binary web service, the binary web service interface being configured to receive information from a node whenever a resource of a node changes or whenever a pre-configured event regarding a resource occurs;

an interface for communicating with web applications making use of the resources; and

a component for receiving subscriptions regarding the information received from the nodes and providing the subscribed information.

14. The system of claim 13, further comprising a second apparatus comprising:

a first binary web service interface to communicate with nodes operationally connected to the apparatus using a binary web service, the binary web service interface being configured to receive information from a node whenever a resource of a node changes or whenever a pre-configured event regarding a resource occurs;

a second binary web service interface for communicating with the first apparatus; and

a component for receiving subscriptions from the first apparatus regarding the information received from the nodes and providing the subscribed information.

15. The system of claim 13, further comprising:

one or more nodes, each node comprising one or more resources operationally connected to the node;

a binary web service interface to communicate with one or more servers operationally connected to the node using a binary web service; and

a subscription processor configured to receive through the binary web service interface subscription request for the node to send a notification whenever a given resource of the node changes and to provide the notification when the resource changes.

16. The system of claim 14, wherein a node of the system further comprises an event processor configured to

detect whenever a pre-configured event regarding a resource occurs;

and

send a notification to a server through the binary web service interface that the event has occurred.

17. A method, comprising:

communicating with nodes operationally connected to the apparatus using a binary web service, the nodes comprising one or more resources;

receiving information from a node whenever a resource of a node changes or whenever a pre-configured event regarding a resource occurs;

receiving subscriptions regarding the information received from the nodes; and

providing the subscribed information.

18. The method of claim 17, further comprising:

requesting a node to send a notification whenever a given resource of the node changes.

19. A method, comprising:

communicating with nodes operationally connected to the apparatus using a binary web service, the nodes comprising one or more resources;

communicating with a server operationally connected to the apparatus;

receiving information from a node whenever a resource of a node changes or whenever a pre-configured event regarding a resource occurs;

receiving subscriptions from the server regarding the information received from the nodes; and

providing the subscribed information.

20. The method of claim 19, further comprising:

requesting a node to send a notification whenever a given resource of the node changes.

21. A method, comprising:

receiving from a server address and property information on one or more resources operationally connected to the server;

sending the server a subscription request regarding a resource to receive a notification from the server whenever a given resource changes; and

receiving a notification from the server when the resource has changed.

22. A computer program distribution medium readable by a computer and encoding a computer program of instructions for executing a computer process carrying out a process, comprising:

communicating with nodes using a binary web service, the nodes comprising one or more resources;

receiving information from a node whenever a resource of a node changes or whenever a pre-configured event regarding a resource occurs;

receiving subscriptions regarding the information received from the nodes; and

providing the subscribed information.

23. A computer program distribution medium readable by a computer and encoding a computer program of instructions for executing a computer process carrying out a process, comprising:

receiving from a server address and property information on one or more resources operationally connected to the server;

sending the server a subscription request regarding a resource to receive a notification from the server whenever a given resource changes; and

receiving a notification from the server when the resource has changed.
