Abstract

A canonical interface for remote interaction with communication devices in a network is described. The canonical interface supports interactions for communicating with remote devices for the configuration of router/communication software or devices; querying run-time information (dynamic and static) and statistics from router/communication software or devices; performing multi-system consistency checking; reporting management events from router/communication software or devices; revision control; and prioritizing urgent network requests over standard network management throughput.

Claims

1. A computer network system for managing a plurality of communications processes operative on a plurality of devices coupled via a network, the computer network system comprising:

one or more tree-based data structures, each of the one or more tree-based data structures including a plurality of nodes arranged in a pre-defined hierarchy for storing a state of one or more communications processes from the plurality of communications processes, wherein the one or more communications processes implements one of a router, a network switch, a firewall, a network encryption process, a mobile communications device;

an application programming interface including a plurality of operations for querying and updating the plurality of nodes in the one or more tree-based data structures;

for reach of the one or more tree-based data structures, one or more network management agents for querying and updating the state of the one or more communications processes based on a state of the one or more data structures, wherein the one or more network management agents are operative to pre-empt low priority queries to the one or more communications processes in response to high-priority update requests for the one or more configuration processes immediately upon receipt of the high priority update requests from the application programming interface;

one or more user interfaces for viewing a content of each of the one or more data structures and performing the plurality of operations, the one or more user interfaces in communication with the one or more data structures via the application programming interface.

2. The computer network system of claim 1, wherein the plurality of operations includes an operation for locking one or more nodes in the one or more tree-based data structures, the locking operations operative to prevent updates to the one or more nodes.

3. The computer network system of claim 2, wherein the plurality of operations includes an operation for locking one or more nodes in the one or more tree-based data structures, the locking operations operative to prevent querying of the one or more nodes.

4. The computer network system of claim 1, wherein the plurality of nodes in the one or more tree-based data structures includes a state of one of more communications protocols by which the one or more communications processes communicates via the network.

5. The computer network system of claim 4, wherein the one or more communications processes implements a router.

6. The computer network system of claim 5, wherein the one or more communications protocols includes Border Gateway Protocol, and one or more of the plurality of nodes stores a current state of the Border Gateway Protocol in the one or more communication processes.

7. The computer network system of claim 5, wherein the one or more communications protocols includes Open Shortest Path First protocol, and one or more of the plurality of nodes stores a current state of the Open Shortest Path First protocol in the one or more communication processes.

8. The computer network system of claim 5, wherein the one or more communications protocols includes Intermediate System-Intermediate System protocol, and one or more of the plurality of nodes stores a current state of the Intermediate System-Intermediate System protocol in the one or more communication processes.

9. The computer network system of claim 5, wherein the one or more communications protocols includes Intermediate System-Intermediate System protocol, and one or more of the plurality of nodes stores a current state of the Intermediate System-Intermediate System protocol in the one or more communication processes.

11. The computer network system of claim 5, wherein the one or more communications protocols includes one or more label-switch protocols, and one or more of the plurality of nodes stores a current state of the label-switched protocols in the one or more communication processes.

12. The computer network system of claim 11, wherein the one or more label-switch protocols includes an RSVP protocol, and one or more of the plurality of nodes stores a current state of the RSVP protocol in the one or more communication processes.

13. The computer network system of claim 11, wherein the one or more label-switch protocols includes an LDP protocol, and one or more of the plurality of nodes stores a current state of the LDP protocol in the one or more communication processes.

14. The computer network system of claim 1, wherein the plurality of operations includes an operation for adding a node to the one or more tree-based data structures.

15. The computer network system of claim 1, wherein the plurality of operations includes an operation for removing a node to the one or more tree-based data structures.

16. The computer network system of claim 1, wherein the plurality of operations includes an operation for clearing contents of a node to the one or more tree-based data structures.

17. The computer network system of claim 1, wherein the plurality of operations includes an operation for clearing operations currently pending on the one or more tree-based data structures.
