Abstract

Embodiments of the present application enable a user to map a network topology and to then dynamically filter the map display by hiding or showing nodes based on discovery characteristics, such as Simple Network Management Protocol (SNMP) status, Active Directory (AD) Domain Controllers (DC) status, group membership status, etc. to allow customization of maps views. In particular, a topology mapping is formed by collecting topology data of a network and storing this topology data. Filtering criteria are received from a user, and the stored topology data is filtered using this received filtering criteria. The filtered topology data is then displayed to the user.

Claims

1. A method for forming a filtered topology mapping, comprising:

collecting topology data of a network;

storing said topology data;

receiving filtering criteria from a user;

filtering stored topology data using said filtering criteria; and

forwarding said filtered topology data to the user.

2. The method of claim 1, wherein the collecting of topology data comprises:

generating synthetic data within the network; and

tracing the synthetic data.

3. The method of claim 1, wherein the collecting of topology data comprises:

searching for nodes in a pre-defined number of internet protocol (ip) addresses;

repeating the search for a predefined number of hops;

determining Layer-2 and Layer-3 connectivity from any discovered nodes;

correlating the Layer-2 and Layer-3 address data; and

determining network connectivity of discovered internet protocol (ip) addresses.

4. The method of claim 1, wherein the collecting of the topology data comprises receiving and storing user preferences comprising a size of the block of ip addresses and the number of hops.

5. The method of claim 1, wherein the filtering criteria comprises a selection of one or more object attributes

6. The method of claim 5, wherein the object attributes comprises object type, simple network management protocol (snmp) status, directory (ad) domain controllers (dc) status, and group membership status.

7. A computer program for forming a topology mapping embodied on a computer-readable medium configured to forming a filtered topology mapping by controlling a processor to perform:

collecting topology data of a network;

storing said topology data;

receiving filtering criteria from a user;

filtering stored topology data using said filtering criteria; and

displaying said filtered topology data to the user.

8. The program of claim 7, wherein the mapping a topology of a network comprises:

generating synthetic data within the network; and

tracing the synthetic data.

9. The program of claim 7, wherein the mapping the topology of the network comprises:

searching for nodes in a pre-defined number of ip addresses;

repeating the search for a predefined number of hops;

determining Layer-2 and Layer-3 connectivity from any discovered nodes;

correlating the Layer-2 and Layer-3 address data; and

determining network connectivity of discovered ip addresses.

10. The program of claim 7, wherein the collecting of the topology data comprises receiving and storing user preferences comprising a size of the block of ip addresses and the number of hops.

11. The program of claim 7, wherein the filtering criteria comprises a selection of one or more object attributes

12. The program of claim 11, wherein the object attributes comprises object type, snmp status, ad dc status, and group membership status.

13. An apparatus for discovering an network topology comprising a server configured to:

collect topology data of a network;

store said topology data;

receive filtering criteria from a user;

filter stored topology data using said filtering criteria; and

display said filtered topology data to the user.

14. The apparatus of claim 13, wherein the server, in the mapping a topology of the network, is further configured to transfer synthetic data within the network, and trace the synthetic data.

15. The apparatus of claim 13, wherein, when mapping the topology the network, the server is further configured to:

search for nodes in a pre-defined number of internet protocol (ip) addresses;

repeat the search for a predefined number of hops;

determine Layer-2 and Layer-3 connectivity from any discovered nodes;

correlate the Layer-2 and Layer-3 address data; and

determine network connectivity of discovered ip addresses.

16. The apparatus of claim 13, wherein the server, when mapping the topology of the network, is further configured to receive and store user preferences comprising the size of the block of ip addresses and the number of hops.

17. The apparatus of claim 13, wherein the filtering criteria comprises a selection of one or more object attributes

18. The method of claim 17, wherein the object attributes comprises object type, snmp status, ad dc status, and group membership status.
