Abstract

Methods and systems are provided to collect and update data on client devices connected to WiFi access points is provided. An inventory of WiFi cable modems and WiFi access points coupled to the WiFi cabled modems within a specific network is periodically collected. Internet Protocol (IP) addresses of WiFi cable modems and WiFi access points coupled to the WiFi cabled modems are periodically updated. Traps are periodically received from the WiFi access points. The traps are parsed to collect an inventory of client devices wirelessly connected to the WiFi access points and a time at which a client device connected to the WiFi access point. The WiFi access points are periodically polled to collect data on client devices, the data including a period of time that a client device has been connected to a WiFi access point and a physical location of the client device.

connecting to the access point to determine a Media Access Control (MAC) address of the access point and an Internet Protocol (IP) address of the access point; and

creating a record having the MAC address of the access point and the IP address of the access point;

determining a current IP address for the access point by connecting to the CMTS; and

updating the IP address for the access point in the record when the current IP address for the access point is not equal to the IP address in the record.

2. The method of claim 1, further comprising:

receiving a notification from the access point;

parsing the notification to collect an inventory of a client device coupled to the access point and a time at which the client device is coupled to the access point; and

polling the access point to collect data including a period of time that the client device has been coupled to the access point and a physical location of the client device.

3. The method of claim 2, wherein the polling comprises:

polling the access point based on an IP address of the cable modem.

4. The method of claim 1, wherein the inventory data includes a number of client devices attempting to access a particular access point of the plurality of access points.

5. The method of claim 2, wherein the physical location of the client device includes approximate Global Positioning Satellite (GPS) coordinates of the client device.

6. The method of claim 2, wherein the parsing comprises:

determining the MAC address and the IP address of the access point based on data from a trap;

determining an access point index, stored in a database, for the access point based on the IP address;

determining a second MAC address and a second IP address for the client device that caused the trap to be generated by the access point based on the trap;

determining a client device index for the client device based on the IP address;

creating a second client index in a database based on the second MAC address when the client device index is not found for the client device;

creating a record with the client index and a device index in the database when the client index is found and the record is not present in the database for that client index for a pre-determined period of time; and

updating the record for the client device with a timestamp that indicates when the trap was generated by the client device when the record is found for the client index in the database.

7. The method of claim 2, wherein the polling comprises:

determining whether the access point has been active for a first pre-determined period of time;

polling the access point when the access point has been active for the first pre-determined period of time to determine whether the client device is coupled to the access point;

determining whether the client device has been coupled to the access point for more than a second pre-determined period of time; and

determining whether a client device index is present in a database using an address of the access point.

8. A system to collect inventory data in a wireless network, comprising:

a memory; and

a processor coupled to the memory, the processor being configured, based on instructions in the memory, to;

connect to a cable modem termination system (CMTS) from among a plurality of CMTSs to collect an inventory of a cable modem coupled to the CMTS;

connect to the cable modem through the CMTS to collect an inventory of an access point of a plurality of access points associated with the cable modem;

connect to the access point to determine a Media Access Control (MAC) address of the access point and an Internet Protocol (IP) address of the access point;

create a record including the MAC address of the access point and the IP address of the access point;

determine a current IP address for the access point by connecting to the CMTS; and

update the IP address for the access point in the record when the current IP address for the access point is not equal to the IP address in the record.

9. The system of claim 8, wherein the instructions further configure the processor to:

receive a notification from the access point;

parse the notification to collect an inventory of a client device coupled to the access point and a time at which the client device is coupled to the access point; and

poll the access point to collect data including a period of time that the client device has been coupled to the access point and a physical location of the client device.

10. The system of claim 8, wherein the instructions configure the processor to poll the access point based on an IP address of the cable modem.

11. The system of claim 8, wherein the inventory data includes a number of client devices attempting to access a particular access point of the plurality of access points.

12. The system of claim 9, wherein the physical location of the client device includes approximate Global Positioning Satellite (GPS) coordinates of the client device.

13. The system of claim 9, wherein to parse, the processor is configured by the instructions to:

determine (MAC) the MAC address and the IP address of the access point based on data from a trap;

determine an access point index, stored in a database, for the access point based on the IP address;
