Abstract

Systems and methods for communicating data between client and server are provided. Method includes facilitating creation of connection comprising tunnel with channels between client side logical interface and server side logical interface. Each channel is associated with port forward of the client side logical interface and the server side logical interface. Client side logical interface and server side logical interface reside on opposite sides of firewall. Client side logical interface is for client protocol interfaces. Server side logical interface is for server protocol interfaces. Method includes receiving data unit for transmission between one of plural clients of client side logical interface and one of plural servers of server side logical interface via connection comprising tunnel. Data unit is associated with OSI model stack identifying source or destination of data unit. Client or server side logical interface provides access to protocols for modifying identified source or destination of data unit.

Claims (35)

1. A computer-implemented method for facilitating communication of data between a client and a server, the method comprising:

facilitating creation of a connection comprising a tunnel with one or more channels between a client side logical interface and a server side logical interface, wherein each channel is associated with a port forward of the client side logical interface and the server side logical interface, wherein the client side logical interface and the server side logical interface reside on opposite sides of a firewall, wherein the client side logical interface is for one or more client protocol interfaces, and wherein the server side logical interface is for one or more server protocol interfaces;

receiving a data unit for transmission between one of plural clients of the client side logical interface and one of plural servers of the server side logical interface via the connection comprising the tunnel, wherein the data unit is associated with an open systems interconnection (OSI) model stack identifying a source or a destination of the data unit, and wherein the client side logical interface or the server side logical interface is configured to provide access to one or more protocols for modifying the identified source or destination of the data unit and for transmitting the data unit;

translating, according to a routing table, between one or more client protocol interfaces and one or more server protocol interfaces; and

facilitating transmission of the data unit via the connection comprising the tunnel.

2. The method of claim 1 , wherein the client side logical interface is one of plural client side logical interfaces coupled with the tunnel.

3. The method of claim 2 , wherein the client side logical interface resides externally to each of the plural clients of the client side logical interface.

4. The method of claim 1 , wherein the server side logical interface is one of plural server side logical interfaces coupled with the tunnel.

5. The method of claim 4 , wherein the server side logical interface resides externally to each of the plural servers of the server side logical interface.

6. The method of claim 1 , wherein the client side logical interface comprises a software interface without a corresponding hardware component.

7. The method of claim 1 , wherein the server side logical interface comprises a software interface without a corresponding hardware component.

8. The method of claim 1 , further comprising:

facilitating specification, via protocol enhancement, of a protocol interface for communication within a channel of the tunnel, wherein the protocol interface is for a protocol for communication between the client side logical interface and the server side logical interface.

9. The method of claim 1 , wherein the one or more protocols for modifying the identified source or destination of the data unit comprise one or more protocols for replacing a header in a specified layer of an open systems interconnection (OSI) model stack for the data unit with a header associated with a modified source or a modified destination.

10. The method of claim 1 , wherein the one or more protocols for modifying the identified source or destination of the data unit comprise one or more protocols for causing the one or more processors to copy data blocks of a first layer of an open systems interconnection (OSI) model stack for the data unit into data blocks of a second layer of the open systems interconnection (OSI) model stack for the data unit, wherein the second layer is a higher number layer than the first layer.

11. A non-transitory machine-readable medium comprising instructions stored therein, the instructions executable by one or more processors to perform a method, the method comprising:

facilitating creation of a connection comprising a tunnel with one or more channels between a client side logical interface and a server side logical interface, wherein each channel is associated with a port forward of the client side logical interface and the server side logical interface, wherein the client side logical interface and the server side logical interface reside on opposite sides of a firewall, wherein the client side logical interface is for one or more client protocol interfaces, and wherein the server side logical interface is for one or more server protocol interfaces;

receiving a data unit for transmission between one of plural clients of the client side logical interface and one of plural servers of the server side logical interface via the connection comprising the tunnel, wherein the data unit is associated with an open systems interconnection (OSI) model stack identifying a source or a destination of the data unit, and wherein the client side logical interface or the server side logical interface is configured to provide access to one or more protocols for modifying the identified source or destination of the data unit and for transmitting the data unit;

translating, according to a routing table, between one or more client protocol interfaces and one or more server protocol interfaces; and

facilitating transmission of the data unit via the connection comprising the tunnel.

12. The non-transitory machine-readable medium of claim 11 , wherein the client side logical interface is one of plural client side logical interfaces coupled with the tunnel.

13. The non-transitory machine-readable medium of claim 12 , wherein the client side logical interface resides externally to each of the plural clients of the client side logical interface.

14. The non-transitory machine-readable medium of claim 11 , wherein the server side logical interface is one of plural server side logical interfaces coupled with the tunnel.

15. The non-transitory machine-readable medium of claim 14 , wherein the server side logical interface resides externally to each of the plural servers of the server side logical interface.

16. The non-transitory machine-readable medium of claim 11 , wherein the client side logical interface comprises a software interface without a corresponding hardware component.

17. The non-transitory machine-readable medium of claim 11 , wherein the server side logical interface comprises a software interface without a corresponding hardware component.

18. The non-transitory machine-readable medium of claim 11 , wherein the method further comprises:

facilitating specification, via protocol enhancement, of a protocol interface for communication within a channel of the tunnel, wherein the protocol interface is for a protocol for communication between the client side logical interface and the server side logical interface.

19. The non-transitory machine-readable medium of claim 11 , wherein the one or more protocols for modifying the identified source or destination of the data unit comprise one or more protocols for replacing a header in a specified layer of an open systems interconnection (OSI) model stack for the data unit with a header associated with a modified source or a modified destination.

20. The non-transitory machine-readable medium of claim 11 , wherein the one or more protocols for modifying the identified source or destination of the data unit comprise one or more protocols for causing the one or more processors to copy data blocks of a first layer of an open systems interconnection (OSI) model stack for the data unit into data blocks of a second layer of the open systems interconnection (OSI) model stack for the data unit, wherein the second layer is a higher number layer than the first layer.

21. A system comprising:

one or more modules configured to facilitate creation of a connection comprising a tunnel with one or more channels between a client side logical interface and a server side logical interface, wherein each channel is associated with a port forward of the client side logical interface and the server side logical interface, wherein the client side logical interface and the server side logical interface reside on opposite sides of a firewall, wherein the client side logical interface is for one or more client protocol interfaces, and wherein the server side logical interface is for one or more server protocol interfaces;

one or more modules configured to receive a data unit for transmission between one of plural clients of the client side logical interface and one of plural servers of the server side logical interface via the connection comprising the tunnel, wherein the data unit is associated with an open systems interconnection (OSI) model stack identifying a source or a destination of the data unit, and wherein the client side logical interface or the server side logical interface is configured to provide access to one or more protocols for modifying the identified source or destination of the data unit and for transmitting the data unit;
