Abstract

A network management system is provided for managing a computer network. The management system is configured to represent the computer network as having one of a plurality of defined network states. Once the state of the network has been identified, the management system can assist the user in making modifications to the computer network and in making recommendations to the user for possible modifications to the computer network. These modifications can include, for example, configuring network devices, removing network devices, replacing network devices, and adding new network devices.

Claims

1. A method of managing a local area network (LAN) having one or more network devices, the method comprising:

defining a plurality of network states, each network state representing a topology of network devices and functions thereof including;

a modem adapted to bridge the local area network (LAN) with a wide area network (WAN),

a wireless access point (WAP) and router adapted to connect the network devices to the modem, and

a voice router adapted for connection between the modem and the wireless access point and router, the voice router adapted to provide phone services to an analog telephone using voice over Internet protocol (VoIP);

identifying a current network state of the local area network (LAN) from the plurality of network states, said current network state representing an existing topology of the one or more network devices and functions thereof in the local area network (LAN);

identifying a next network state of the local area network (LAN) from the plurality of network states, said next network state representing a change to the current network state, said next network state representing an enhanced topology of network devices and functions thereof in the local area network (LAN);

recommending the next network state to a user; and

providing the user with instructions for modifying the existing topology of the one or more network devices and functions thereof in the local area network (LAN) based on the current network state to the enhanced topology of network devices and functions thereof in the local area network (LAN) based on the next network state.

2. The method of claim 1, wherein:

said identifying the current network state comprises detecting the existing topology of network devices of the local area network (LAN) and determining the network state corresponding to the detected topology of network devices.

3. The method of claim 1, further comprising:

identifying a new device to be added to the local area network (LAN); and

based on the current network state, selecting a state transition routine for managing the addition of the new device to the local area network (LAN).

4. The method of claim 3, wherein:

said identifying the new device to be added to the local area network (LAN) comprises detecting a connection of the new device to the local area network (LAN).

5. The method of claim 3, wherein:

said identifying the new device to be added to the local area network (LAN) comprises receiving an input from a user indicating the new device to be added to the local area network (LAN).

6. The method of claim 3, further comprising:

executing the state transition routine to provide instructions to a user for changing the topology of the local area network (LAN).

7. The method of claim 6, wherein:

said providing instructions to the user for changing the topology of the local area network (LAN) comprises providing instructions to the user for manually connecting computer hardware.

8. The method of claim 6, wherein:

said providing instructions to the user for changing the topology of the local area network (LAN) comprises providing instructions to the user for adjusting configuration settings.

9. The method of claim 6, wherein:

said changing the topology of the local area network (LAN) comprises replacing one of the network devices in the local area network (LAN) with another network device of the same network device type.

10. The method of claim 6, wherein:

said changing the topology of the local area network (LAN) comprises adding a new network device to the local area network (LAN).

11. The method of claim 1, wherein:

recommending the next network state to the user is based on the current network state and includes recommending a change to the existing topology of network devices in the local area network (LAN).

12. The method of claim 11, wherein:

said recommending the change to the existing topology comprises selecting the recommended next network state from a group of potential network state transitions available for the identified network state.

13. The method of claim 1, further comprising:

identifying a group of potential network state transitions available for the identified network state, wherein a preference value is assigned to each of the potential network state transitions in the group of potential network state transitions.

14. The method of claim 13, further comprising:

in response to detecting an attempt to change to a new network state, wherein a preference value for the new network state is inferior to a preference value for the current network state, warning a user of the inferiority of the new network state.

15. The method of claim 13, further comprising:

recommending to the user a network state transition based on the preference value of the recommended network state transition.

16. The method of claim 1, further comprising:

generating a network state report including information regarding the current network state.

17. The method of claim 16, wherein:

said network state report includes information regarding configuration settings of peripheral devices on the network.

18. The method of claim 1, wherein:

said plurality of network states comprises a plurality of core states, each core state representing a topology of core network device types.

19. A non-transitory computer readable medium on which are stored computer readable instructions for managing a local area network (LAN) having one or more network devices and, when executed by a computer, the computer is operable to:

define a plurality of network states, each network state representing a topology of network devices and functions thereof including;

a modem adapted to bridge the local area network (LAN) with a wide area network (WAN),

a wireless access point (WAP) and router adapted to connect the network devices to the modem, and

a voice router adapted for connection between the modem and the wireless access point and router, the voice router adapted to provide phone services to an analog telephone using voice over Internet protocol (VoIP);

identify a current network state of the local area network (LAN) from the plurality of network states, said current network state representing an existing topology of the one or more network devices and functions thereof in the local area network (LAN);

identify a next network state of the local area network (LAN) from the plurality of network states, said next network state representing a change to the current network state, said next network state representing an enhanced topology of network devices and functions thereof in the local area network (LAN);

recommend the next network state to a user; and

provide the user with instructions for modifying the existing topology of the one or more network devices and functions thereof in the local area network (LAN) based on the current network state to the enhanced topology of network devices and functions thereof in the local area network (LAN) based on the next network state.

20. The computer readable medium of claim 19, wherein the computer is operable to:

detect the existing topology of network devices of the local area network (LAN); and

determine the network state corresponding to the detected topology of network devices.

21. The computer readable medium of claim 19, wherein the computer is operable to:

identify a new device to be added to the local area network (LAN); and
