Abstract

A method of automatic network topology determination for at least one Control & Instrumentation (C&I) system in an industrial facility. A network type, and all nodes and interconnecting networking devices including switches in the C&I system(s) are discovered. Additional connectivity information including a connection of the nodes to a specific port is collected. The network relationships of the nodes and interconnecting networking devices in the C&I system are determined. A network topology diagram of the C&I system is automatically generated from the nodes and interconnecting networking devices, additional connectivity information, and network relationships.

First claim

The invention claimed is:

1. A method of network topology determination for at least one Control & Instrumentation (C&I) system in an industrial facility (IF), comprising:
discovering a network type, and all nodes and interconnecting networking devices including switches in said IF C&I system, said IF C&I system comprising a first C&I system and a second C&I system, using at least one data agent in a data agent block and said at least one data agent comprises a first data agent and a second data agent, said first data agent compatible with a first operating system (OS) in said first C&I system, and said second data agent is compatible with a second OS used in said second C&I system that is different from said first OS;
collecting additional connectivity information including a connection of said nodes to a specific port;
determining network relationships of said nodes and said interconnecting networking devices in said IF C&I system, by obtaining port to Media Access Control (MAC) address mapping data from a MAC table stored at said switches and Address Resolution Protocol (ARP) data from an ARP table stored at a server in said IF C&I system;
determining at least one of node type and node address that including which node of which type with what IP address is connected to which port of which switch present in the network, for a network topology diagram; and
generating the network topology diagram of said IF C&I system from said nodes and said interconnecting networking devices, said additional connectivity information, and said network relationships,
wherein said discovering, said collecting, said determining, and said generating are all automatically implemented.

2. The method of claim 1 , further comprising determining inter-connection details between said first and second C&I systems without any additional inputs from an end user.

3. The method of claim 1 , further comprising protecting confidential or proprietary data to exclude intellectual property data or trade secrets from said method using an exclusion list.

4. The method of claim 1 , further comprising upon choosing a selected node from said nodes, displaying related information of said selected node including an object type, model number, port number that said selected node is connected to, and maintenance records for said selected node.

5. The method of claim 1 , further comprising a search option to enable a user to use said search option for locating one particular node of said nodes.

6. The method of claim 1 , further comprising selecting a first node from said nodes in said network topology diagram, and responsive to said selecting switching to a physical view to determine where said first node is physically located.

7. The method of claim 1 , further comprising selecting a first node from said nodes in said network topology diagram, and responsive to said selecting switching to logical view to see a logical association of said first node.

8. The method of claim 1 , wherein said network topology diagram provides different representations for different network topologies present in said C&I IF system.

9. An automatic network topology determination (ANTD) system, comprising:
a processor having associated memory which stores a data collection algorithm run by the processor for implementing a data collection system coupled to a data agent block including a data agent list which includes at least one data agent in said data agent block registered with said data collection system, said data collection system coupled to said data agent block configured to be coupled between a data server and at least one C&I system of an industrial facility (IF), said data collection algorithm:
discovering a network type, and all nodes and interconnecting networking devices including switches in said IF C&I system, said IF C&I system comprising a first C&I system and a second C&I system, said at least one data agent comprises a first data agent and a second data agent, said first data agent compatible with a first operating system (OS) in said first C&I system, and said second data agent is compatible with a second OS used in said second C&I system that is different from said first OS;
collecting additional connectivity information including a connection of said nodes to a specific port;
determining network relationships of said nodes and said interconnecting networking devices in said IF C&I system, by obtaining port to Media Access Control (MAC) address mapping data from a MAC table stored at said switches and Address Resolution Protocol (ARP) data from an ARP table stored at a server in said IF C&I system;
determining at least one of node type and node address that including which node of which type with what IP address is connected to which port of which switch present in the network, for a network topology diagram; and
generating the network topology diagram of said IF C&I system from said nodes and said interconnecting networking devices, said additional connectivity information, and said network relationships,
wherein said discovering, said collecting, said determining and said generating are all automatically implemented by said ANTD system.

10. The ANTD system of claim 9 , wherein said data collection algorithm further comprises code for determining inter-connection details between said first and said second C&I systems without any additional inputs from an end user.

11. The ANTD system of claim 9 , said data collection algorithm further comprising code for protecting confidential or proprietary data to exclude intellectual property data or trade secrets using an exclusion list.

12. The ANTD system of claim 9 , said data collection algorithm further comprising code for upon choosing a selected node from said nodes, displaying related information of said selected node including an object type, model number, port number where said selected node is connected to, and maintenance records for said selected node.

13. The ANTD system of claim 9 , said data collection algorithm further comprising code for a search option to enable a user to use said search option for locating one particular node of said nodes.

14. The ANTD system of claim 9 , said data collection algorithm further comprising code for selecting a first node from said nodes in said network topology diagram, and responsive to said selecting switching to a physical view to determine where said first node is physically located.

15. The ANTD system of claim 9 , said data collection algorithm further comprising code for selecting a first node from said nodes in said network topology diagram, and responsive to said selecting switching to logical view to see a logical association of said first node.

16. The ANTD system of claim 9 , said data collection algorithm further comprising code said network topology diagram providing different representations for different network topologies present in said IF C&I system.
