Abstract

Systems, software, and methods for managing networks of connected electronic devices are described. In one example, network management policy and network management applications are downloaded automatically upon detection and identification of a new device on the network. In another example, information related to at least one aspect of the network is obtained by a network management device, and at least one applicable management policy is identified by the device; and the identified policy is used to manage at least one aspect of the network'"'"'s operation.

Claims

1. A network management system comprising:

a network management device processor executing a network management application operably connected to a network infrastructure;

the network management device processor executing a first discovery application configured to perform a port mapping operation; and

the network management device processor using results of the port mapping operation to select and execute a task specific discovery application for gathering information about each network connected device that responds to the port mapping operation,

the network management device processor executing plural task specific discovery applications, each of the plural task specific discovery applications being configured to discover a different operating characteristic of a network connected device that responds to the port mapping operation;

the network management device processor being further configured to use results provided by a first task specific discovery application to select and execute at least one subsequent task specific discovery application in order to discover additional operating characteristics of the network connected device and to use the additional task discovery application results to further iterate said selection and execution until each network connected device that responds to the port mapping operation has been characterized;

the network management device processor searching for and dynamically selecting a dynamically selected policy template and using the dynamically selected policy template to manage at least one aspect of the network.

2. The network management system of claim 1 wherein the at least one subsequent task specific discovery application operating on the network management device is operable to discover previously unknown network connected devices and previously unknown applications running on network connected devices.

3. The network management system of claim 2 wherein the task specific discovery application is operable without installing a software agent onto the network connected device.

4. The network management system of claim 3 further comprising a network connected data storage device reachable by the network management device processor, the network connected data storage device being configured to store a plurality of task specific discovery applications, the network management device processor being operable to select a sequence of task specific discovery applications stored by the network connected data storage device to execute on the network management device processor as needed to gather information about a network connected device that responds to the port mapping operation.

5. The network management system of claim 1 wherein the network management device comprises a distributed arrangement with portions of the network management device operating on a plurality of different network connected devices.

6. The network management system of claim 5 wherein at least a portion of the plurality of different network connected devices are connected to different networks.

7. The network management system of claim 1 further comprising the processor executing a collector application operable to collect, aggregate and manage the results of the port mapping operation and the results of at least one task specific discovery application and to conform data associated with each network connected device to one or more relevant data definition templates.

8. The network management system of claim 7 further comprising the processor executing a classifier application operable to review a data definition template provided by the collector application and to identify for each network connected device further data that place the network connected device that responds to the port mapping operation under management.

9. The network management system of claim 8 further comprising the processor executing a recognizer application operable to review the further data to place the network connected device that responds to the port mapping operation under management and to select a further task specific discovery application to execute that collects the further data to place the network connected device that responds to the port mapping operation under management.

10. The network management system of claim 1 further comprising the processor executing a template manager application operable to dynamically configure and update a point of management template associated with each network connected device that responds to the port mapping operation, wherein the point of management template describes characteristics of a network connected device that responds to the port mapping operation and provides a mapping between the sequence of task specific discovery applications and network connected devices that respond to the port mapping operation.

11. The network management system of claim 1 further comprising a plurality of network device instances each comprising:

a network management device processor instance;

a template manager application operating on the network management device processor instance to manage data definition templates for the network device instance;

a plurality of data definition templates stored on a data store in communication with the network management device processor instance;

a data store manager application operating on the network management device processor instance;

wherein each network management device processor instance is operable to automatically share its template data store with one or more other network device instances by one of a real time data sharing model and a publish-and-subscribe data sharing model.

12. The network management system of claim 1 further comprising the network management device processor executing a dynamic application for monitoring network protocol with quality of service metrics.

13. The network management system of claim 1 wherein at least one of the applications includes a dynamic DNS quality of service component for monitoring DNS/DHCP addressing infrastructure.

14. The network management system of claim 1 wherein at least one of the applications includes a DHCP discovery application for monitoring DHCP services.

15. The network management system of claim 1 wherein at least one of the applications includes a HTTP/HTTPS discovery application and a dynamic HTTP/HTTPS quality of service component for monitoring one or more HTTP/HTTPS quality of service metrics.

16. A method performed by at least one processor comprising:

(a) discovering, with the processor over a network, at least one aspect of a network-connected electronic device;

(b) based at least in part on the discovered information, selecting and executing a first dynamic application that gives the processor capability for discovering over the network at least one further aspect of the network-connected electronic device, said selecting and executing being performed on an as-needed basis;

(c) searching for and downloading a policy template on demand in response to discovering at least one aspect of the network-connected electronic device, said policy template comprising a data structure that defines information the first dynamic application is to collect;

(d) using the policy template to identify at least one management policy for use to manage the network-connected electronic device;

(e) using said identified management policy to select a second dynamic application different from the first dynamic application; and

(f) executing said selected second dynamic application to manage at least one aspect or characteristic of the network in accordance with the identified management policy, thereby replacing the first dynamic application with the second dynamic application at least in part in response to discovered or collected information.

17. The method of claim 16, wherein selecting the second dynamic application includes selecting, at least in part, based upon the discovered or collected information.
