Network management system having a network database
First Claim
1. A network including at least an ECHELON network component comprising:
- a first node, on the ECHELON network component, executing a network database manager maintaining a network database of connectivity information and responsive to network management service requests from client applications via a network service provider;
a second node on the ECHELON network component;
a first ECHELON network connection between the second node and the first node on the ECHELON network component and wherein the network database includes connectivity information corresponding to the ECHELON network connection.

Abstract
A network management system includes an embedded node, having network database and communications elements, which is coupled locally on an ECHELON network. This local coupling provides a relatively high bandwidth connection to accommodate relatively high traffic volume between the network database and nodes for improved system performance relative to prior art configurations. Locally coupling the network database to the network eliminates the need to tunnel various messages needed to effect a network service when using a tiered architecture common in the HVAC industry. The communications elements include com ports adapted to couple the embedded node to a workstation via a conventional network, and to an ECHELON network.

13. The network as set forth in claim 1, further comprising at least a network service provider node connected to the ECHELON network component, and wherein the network service provider node supports a plurality of client applications.
-
14. The network as set forth in claim 13, wherein the first node is adapted for being communicatively coupled to the network service provider node.
-
15. A network information management node for incorporation in an ECHELON network comprising:
-
a network database manager;
a network database coupled to said network database manager;
wherein the network database manager responds to network management service requests from multiple client applications; and
wherein the network database includes connection tables for storing connectivity information corresponding to connections to nodes on the ECHELON network. - View Dependent Claims (16, 17, 18)
a first network interface facilitating communications between the network database manager and nodes residing on the ECHELON network; and
a second network interface facilitating communications between the network database manager and client applications executing upon at least one node residing on a second network distinct from the ECHELON network.
-
-
18. The network information management node of claim 15 wherein the first network interface executes a first communications protocol and the second network interface executes a second communications protocol that differs from the first communications protocol.
-
19. A method of operating a network including an ECHELON network component said method comprising:
-
executing at least one application program in a first computer;
executing a network service provider on the first computer, the network service provider being communicably coupled with the at least one application program to facilitate access to a network database management service for the at least one application program; and
executing a network database manager on a second computer coupled to the ECHELON network, the network database manager being communicably coupled to the network service provider to facilitate providing the network database management service to the network service provider.- View Dependent Claims (20)
creating a message queue;
creating a wait queue on the second computer for requests, from the second computer, for the network database manager service;
receiving, by the network database manager, network database management service requests;
receiving, by the second computer, LONTALK messages over said ECHELON network;
processing, by the network database manager, LONTALK messages relating to a current network management service request through said message queue; and
storing, by the second computer, messages relating to other than current network database management service requests on said wait queue.
