Abstract

According to an embodiment of the present disclosure there is provided a method of facilitating the execution of a remote procedure call on a first network device, the first network device not being directly addressable from the network. The method comprises: receiving, at a connection manager, from the first network device, a first request message to establish a connection with the first network device, the request message including an identifier; establishing a first connection with the first network device and the connection manager, the first connection being associated with the identifier; receiving, at an interface module, a second request message from a second network device to execute a remote procedure call on the first network device, the second request message including the identifier; establishing a second connection with the interface module and the connection manager; associating, the first connection with the second connection; and forwarding the received request to the first network device over the first connection.

Claims

1. A method of facilitating the execution of a remote procedure call on a first network device, the first network device not being directly addressable from the network, comprising:

receiving, at a connection manager, from the first network device, a first request message to establish a connection with the first network device, the request message including an identifier;

establishing a first connection with the first network device and the connection manager, the first connection being associated with the identifier;

receiving, at an interface module, a second request message from a second network device to execute a remote procedure call on the first network device, the second request message including the identifier;

establishing a second connection with the interface module and the connection manager;

associating, the first connection with the second connection; and

forwarding the received request to the first network device over the first connection.

2. The method of claim 1, further comprising:

receiving over the first connection a response message;

determining the second connection associated with the first connection; and

forwarding the response message over the determined second connection.

3. The method of claim 1, wherein the first network device has a private Internet protocol address.

4. The method of claim 1, wherein the interface module has an interface described using the web services description language, or WSDL, the WDSL description describing a web interface of the first network device.

5. The method of claim 4, wherein the step of receiving the second request message further comprises receiving, from an application server running on the second network device, a HTTP request message comprising SOAP encapsulated remote procedure call request message formatted in accordance with the WDSL description.

6. The method of claim 1, further comprising decoding the received message, serializing the received remote procedure call request message and forwarding the serialized message over the first connection.

7. The method of claim 2, wherein the step of receiving the response message comprises receiving a serialized response message, the method further comprising un-serializing the message, formatting the message in accordance with a WSDL description of the second network device, and forwarding the formatted message over the associated second connection.

8. Apparatus for facilitating the execution of a remote procedure call on a first network device, the first network device not being directly addressable from the network, comprising:

a connection manager to receive, from the first network device, a request to establish a connection with the first network device, the request including an identifier, the connection manager being arranged to establish a first connection with the first network, and to associate the first connection with the identifier;

an interface module to receive, from a second network device, a request to execute a remote procedure call on the first network device, the request message including the identifier;

the connection manager being further arranged to establish a second connection with the interface module and to associate the first and second connections;

the connection manager being further arranged to forward the received request to the first network device over the first connection.

9. The apparatus of claim 8, the connection manager being further arranged to:

receive, over the first connection, a response message;

determine the second connection associated with the first connection; and

forward the response message over the determined second connection.

10. The apparatus of claim 8, wherein the first network device has a private Internet protocol address.

11. The apparatus of claim 8, wherein the interface module has an interface described using the web services description language, or WSDL, the WDSL description describing a web interface of the first network device.

12. The apparatus of claim 11, wherein the interface module is arranged to receive, from an application server running on the second network device, a HTTP request message comprising a SOAP encapsulated remote procedure call request message formatted in accordance with the WDSL description.

13. The apparatus of claim 8, the interface module arranged to:

decode the received message;

serialize the received remote procedure call request message; and

forward the serialized message over the second connection for further forwarding by the connection manager over the first connection.

14. The apparatus of claim 8, wherein the connection manager is further adapted to:

receive the response message comprises receiving a serialized response message;

un-serializing the message;

format the message in accordance with a WSDL description of the second network device; and

forward the formatted message over the associated second connection.

15. A first network device operable for use with the apparatus of claim 8.

16. A second network device operable for use with the apparatus of claim 8.

17. A method of facilitating the execution of a remote procedure call on a first network device, the first network device not being directly addressable from the network, comprising:

receiving, from the first network device, a first request message to establish a connection from the first network device, the request message including an identifier;

establishing a first connection with the first network device, the connection being associated with the identifier;

receiving, a second request message from a second network device to execute a remote procedure call on the first network device, the second request message including the identifier;

establishing a second connection with the second network device, the connection being associated with the identifier;

associating, the first connection with the second connection; and

forwarding the received request to the first network device.
