Network management systems for use with physical layer information
One exemplary embodiment is directed to a network management system that uses physical layer information in performing a network management function. Another exemplary embodiment is directed to a method of tracking channel compliance using physical layer information.
1. A system comprising:
a plurality of patch panels, each of the patch panels comprising a plurality of ports, wherein each of the patch panels is configured to read cable information stored in storage devices associated with connected attached to cables that are connected to the ports of the respective patch panel;
an aggregation point communicatively coupled to the plurality of patch panels, wherein each of the patch panels is configured to send at least some of the cable information read from the storage device associated with the connectors attached to the cables that are connected to the ports of the respective patch panel to the aggregation point and wherein the aggregation point is configured to receive the cable information sent by the patch panels and wherein the aggregation point is configured to store at least some of the cable information sent by the patch panels to the aggregation point; and
a network management system (NMS) that is communicatively coupled to the aggregation point, wherein the NMS is configured to receive at least a portion of the cable information that is read from the storage devices associated with the connectors attached to the cables that are connected to the ports of the patch panels and stored by the aggregation point and wherein the NMS is configured to use at least some of the cable information received from the aggregation point in performing a network management function; and
wherein the aggregation point is configured to automatically discover the patch panels and cause each of the patch panels to send to the aggregation point at least some of the cable information read from the storage devices associated with the connectors attached to the cables that are connected to the ports of the respective patch panels.
2. The system of claim 1 , wherein the NMS displays a graphical representation of a network, wherein the graphical representation shows at least one logical communication link between network elements; and
wherein the NMS is configured to display various physical layer items that implement that logical communication link using at least some of the cable information received from the aggregation point.
3. The system of claim 1 , wherein the NMS is configured to carry out guided moves, adds, and changes of cabling using the cable information read from a storage device associated with a connector attached to the involved cable.
4. The system of claim 1 , wherein the NMS is configured to receive the cable information from the aggregation point using at least one of the Simple Object Access Protocol (SOAP) and the Simple Network Management Protocol (SNMP).
5. The system of claim 1 , wherein the aggregation point comprises middleware that provides an application programming interface (API) by which the NMS is able to access at least some of the cable information stored by the aggregation point.
6. The system of claim 1 , wherein the patch panels comprise at least one of a fibre-optic patch panel and copper-cable patch panel.
7. The system of claim 1 , wherein the patch panels comprises at least one of a fiber splice panel and a fiber splice tray.
8. The system of claim 1 , wherein the cable information comprises information about the respective connector attached to one or more of the cables.
9. The system of claim 1 , wherein the cable information comprises information related to at least one of an identifier that uniquely identifies one or more the cables, a part number associated with one or more of the cables, a connector type associated with one or more of the cables, a media type associated with one or more of the cables, a length associated with one or more of the cables, a serial number associated with one or more of the cables, a cable polarity, a date of manufacture associated with one or more of the cables, a manufacturing lot number associated with one or more of the cables, a visual attribute associated with one or more of the cables, a visual attribute associated with the respective connector attached to one or more of the cables, an insertion count associated with one or more of the cables, an Enterprise Resource Planning system, test data associated with one or more of the cables, media quality data associated with one or more of the cables, and performance data associated with one or more of the cables.
10. The system of claim 1 , wherein the aggregation point is further configured to receive and store at least one of:
information about the patch panels;
information about a layout of one or more buildings in which the patch panels are deployed;
information about locations of the patch panels or the cables;
information about end-user devices;
information about the location of a voice-over-internet-protocol telephony device;
information that is manually entered and uploaded to the aggregation point; and
information about local conditions and requirements associated with each of the patch panels.
11. The system of claim 1 , wherein the aggregation point is further configured to receive and store at least one of information about the compliance of one or more components with one or more specifications, information about the compliance of a permanent link with one or more specifications, and information about the compliance of a channel with one or more specifications.
12. The system of claim 1 , wherein each storage device comprises non-volatile memory.
13. The system of claim 1 , wherein the cables comprise at least one of a copper cabling or an optical fiber cabling.
14. The system of claim 1 , wherein the cables comprise at least one metallic cable.
15. The system of claim 1 , wherein the cables comprises at least one fiber optic cable.
16. The system of claim 1 , wherein at least one of the cables is used to implement at least a portion of a logical communication link.
17. The system of claim 1 , wherein at least one of the cables is used to implement logical communication links.
18. The system of claim 1 , wherein the ports of the patch panels are configured to connect to connectors attached to cables to implement portions of logical communication links.
19. The system of claim 14 , wherein the metallic cable includes an RJ- 45 modular jack connected to at least one end.
20. The system of claim 15 , wherein the fiber optic cable includes an LC connector,
an SC connector, an ST connector, or an MPO connector connected to at least one end thereof.
