Abstract

This disclosure describes a context aware scalable dynamic network whereby network information concerning network elements in an untrusted (Black) network are gathered by network sensors, stored at a network sensor collector, and sent to another network sensor collector in a trusted (Red) network through a one-way guard. At the Red network, the network information from the Black network may be combined with network information from one or more Red networks. The combined network information may then be used to visualize a cross-domain network topology of both Red and Black networks, and to implement network management functions.

Claims

1. A method for providing network management, the method comprising:

gathering first network information from first network elements in one or more trusted networks;

receiving second network information through a one-way guard, the second information from second network elements in one or more untrusted networks;

correlating one or more data flows associated with the first network information to one or more encrypted data tunnels associated with the second network information to form fused network information;

generating a cross-domain network topology for the one or more trusted networks and the one or more untrusted networks; and

managing at least one of the second network elements identified in the cross-domain topology.

2. The method of claim 1, wherein managing the at least one of the second network elements identified in the cross-domain topology comprises:

querying data from the at least one of the second network elements.

3. The method of claim 2, further comprising:

querying data from the at least one of the second network elements using simple network management protocol (SNMP).

4. The method of claim 1, wherein managing the at least one of the second network elements identified in the cross-domain topology comprises:

setting network management data at the at least one of the second network elements identified in the cross-domain topology.

5. The method of claim 4, further comprising:

setting network management data at the at least one of the second network elements identified in the cross-domain topology using simple network management protocol (SNMP).

6. The method of claim 1, further comprising:

managing at least one of the first network elements identified in the cross-domain topology.

7. The method of claim 1, further comprising:

storing the first network information and the second network information in a database located in a first trusted network of the one or more trusted networks.

8. The method of claim 7, further comprising:

sending the first network information and the second network information from the database to a second trusted network of the one or more trusted networks.

9. The method of claim 1, wherein the first network elements and the second network elements may be one or more of an inline network encryptor, a router, or a switch.

10. An apparatus comprising:

a computing device located in a first trusted network of one or more trusted networks, the computing device executing a network management system, the computing device comprising;

a database configured to store network information; and

one or more processors configured to;

gather first network information from first network elements in the one or more trusted networks;

receive second network information through a one-way guard, the second information from second network elements in one or more untrusted networks;

correlate one or more data flows associated with the first network information to one or more encrypted data tunnels associated with the second network information to form fused network information;

generate a cross-domain network topology for the one or more trusted networks and the one or more untrusted networks; and

manage at least one of the second network elements identified in the cross-domain topology.

11. The apparatus of claim 10, wherein to manage the at least one of the second network elements identified in the cross-domain topology, the one or more processors are further configured to:

query data from the at least one of the second network elements.

12. The apparatus of claim 11, wherein the one or more processors are further configured to:

query data from the at least one of the second network elements using simple network management protocol (SNMP).

13. The apparatus of claim 10, wherein to manage the at least one of the second network elements identified in the cross-domain topology, the one or more processors are further configured to:

set network management data at the at least one of the second network elements identified in the cross-domain topology.

14. The apparatus of claim 13, wherein the one or more processors are further configured to:

set network management data at the at least one of the second network elements identified in the cross-domain topology using simple network management protocol (SNMP).

15. The apparatus of claim 10, wherein the one or more processors are further configured to:

manage at least one of the first network elements identified in the cross-domain topology.

16. The apparatus of claim 10, wherein the one or more processors are further configured to:

store the first network information and the second network information in the database.

17. The apparatus of claim 16, wherein the one or more processors are further configured to:

send the first network information and the second network information from the database to a second trusted network of the one or more trusted networks.

18. A computer-readable storage medium storing instructions that, when executed, cause one or more processors to:

gather first network information from first network elements in one or more trusted networks;

receive second network information through a one-way guard, the second information from second network elements in one or more untrusted networks

receive at least the second network information through a one-way guard;

correlate one or more data flows associated with the first network information to one or more encrypted data tunnels associated with the second network information to form fused network information;

generate a cross-domain network topology for the one or more trusted networks and the one or more untrusted networks; and

manage at least one of the second network elements identified in the cross-domain topology.

19. The computer-readable storage medium of claim 18, wherein the instructions further cause the one or more processors to:

query data from the at least one of the second network elements.

20. The computer-readable storage medium of claim 18, wherein the instructions further cause the one or more processors to:

set network management data at the at least one of the second network elements identified in the cross-domain topology.
