3. The computer network according to claim 2 , wherein the polled answers in reaction to the single bulk request are provided to the network management tools.
4. The computer network according to claim 3 , wherein the polled answers in reaction to the single bulk request are provided to the network management tools via requests for the same content as a previously sent single bulk request.
5. The computer network system according to claim 1 , wherein a polling interval is defined by the requests from the different network management tools.
6. The computer network system according to claim 1 , wherein the proxy further comprises a communication component to each of the network management tools.
7. The computer network system according to claim 1 , wherein the proxy further comprises a communication component to said one of the hardware devices.
8. The computer network system according to claim 1 , wherein the proxy translates a duplicate network address to a unique network address.
9. A network setup method for monitoring and controlling at least one hardware device of a network segment comprising a plurality of hardware devices by a plurality of network management tools, the method comprising:
the different network management tools sending to a proxy a multitude of requests for information from the at least one hardware device;
the proxy combining a plurality of the requests into a single combined request and sending said combined request to the at least one hardware device to obtain from said at least one of the hardware devices the information requested by said plurality of the requests from the different network management tools; wherein the proxy includes a database for storing the requests from the different network management tools, a configuration unit for consolidating the requests from the different network management tools into a single bulk request, and a polling unit for initiating the single bulk request on said one of the hardware devices; and
the configuration unit compiling the requests to a configuration for the polling unit; and wherein:
each of the hardware devices has an IP address and some of the hardware devices have duplicate ones of the IP addresses;
the proxy receives packets from the hardware devices, each of said packets including the IP address of the hardware device that sent said each packet;
when the proxy receives one of the data packets from one of the hardware devices having one of the duplicate IP addresses, the proxy changes the IP address in said one of the data packets to translate the duplicate IP address in said one of the data packets to a unique address to enable the network management tools to work with hardware devices with duplicate IP addresses.
10. The method according to claim 9 , further comprising storing in the database polled answers in reaction to the single bulk request.
11. The method according to claim 10 , further comprising providing the polled answers in reaction to the single bulk request to the network management tools.
12. The method according to claim 11 , wherein the providing the polled answers in reaction to the single bulk request includes providing the polled answers in reaction to the single bulk request to the network management tools via requests for the same content as a previously sent single bulk request.
13. The method according to claim 9 , further comprising the requests from the different network management tools defining a polling interval.
14. The method according to claim 9 , wherein the proxy further comprises a communication component to each of the network management tools.
15. The method according to claim 9 , wherein the proxy further comprises a communication component to said one of the hardware devices.
16. A computer program product comprising a tangible computer-readable non-transitory storage device and a computer program tangibly stored on the computer-readable device with program coding for operating a proxy of a computer network system, the computer network system comprising a plurality of network management tools, and a network segment comprising a plurality of hardware devices, wherein each of the network management tools is assigned at least one functionality for monitoring and controlling at least one of the hardware device, and the different network management tools send to the proxy a multitude of requests for information from the at least one of the hardware devices, the proxy including a database, a configuration unit, and a polling unit, and the computer program performing:
the proxy combining a plurality of the requests into a single combined request and sending said combined request to the at least one hardware device to obtain from said at least one of the hardware devices the information requested by said plurality of the requests from the different network management tools, including storing in the database the requests from the different network management tools, the configuration unit consolidating the requests from the different network management tools into a single bulk request, and the polling unit initiating the single bulk request on said one of the hardware devices; and
the configuration unit compiling the requests to a configuration for the polling unit; and wherein:
each of the hardware devices has an IP address and some of the hardware devices have duplicate ones of the IP addresses;
