Dynamic update of virtual network topology
An IP network topology update system may update IP network topology in near real-time and on-demand with minimum overheads. It identifies likely impact area (e.g., layer 2 or layer 3), objects (e.g., link or node such a device), and timing (e.g., what topology objects located where or when the topology update process should be performed) in the IP Layer 3 network and its underlying SDN Layer 2 network under virtualized networking infrastructure as candidates of impacts for topology update.
1. An apparatus comprising:
a processor; and
a memory coupled with the processor, the memory comprising executable instructions stored thereon that when executed by the processor cause the processor to effectuate operations comprising:
obtaining an alert, the alert comprising information affecting a virtual topology;
determining that the alert is a parent event during a time duration, the time duration computed based on a pairing of a time of an onset alarm and a time of a clear alarm associated with a same alarm identifier from a same device;
based on the determining that the alert is a parent event, determining an object associated with the parent event;
obtaining other parent events that are associated with the object;
based on the other parent events that are associated with the object, determining an impact area that the parent event affects; and
based on the determined impact area, performing a topology update for the impact area.
2. The apparatus of claim 1 , the operations further comprising:
providing instructions to display the topology update on a display of a device.
3. The apparatus of claim 1 , wherein the impact area comprises a layer 2 area or a layer 3 area.
4. The apparatus of claim 1 , wherein the object comprises a virtual network device.
5. The apparatus of claim 1 , wherein the object comprises a physical network device.
6. The apparatus of claim 1 , wherein the object comprises a physical link.
7. The apparatus of claim 1 , wherein the object comprises a virtual link.
8. A method comprising:
obtaining, by a server, an alert, the alert comprising information affecting a virtual topology;
determining, by the server, that the alert is a parent event during a time duration, the time duration computed based on a pairing of a time of an onset alarm and a time of a clear alarm associated with a same alarm identifier from a same device;
based on the determining that the alert is a parent event, determining, by the server, an object associated with the parent event;
obtaining, by the server, other events that are associated with the object;
based on the other events that are associated with the object, determining, by the server, an impact area that the parent event affects; and
based on the determined impact area, performing a topology update for the impact area.
9. The method of claim 8 , further comprising:
displaying the topology update on a display of a device.
10. The method of claim 8 , wherein the impact area comprises a layer 2 area or a layer 3 area.
11. The method of claim 8 , wherein the object comprises a virtual network device.
12. The method of claim 8 , wherein the object comprises a physical network device.
13. The method of claim 8 , wherein the object comprises a physical link.
14. The method of claim 8 , wherein the object comprises a virtual link.
15. A non-transitory computer readable storage medium storing computer executable instructions that when executed by a computing device cause said computing device to effectuate operations comprising:
obtaining an alert, the alert comprising information affecting a virtual topology;
determining that the alert is a parent event during a time duration, the time duration computed based on a pairing of a time of an onset alarm and a time of a clear alarm associated with a same alarm identifier from a same device;
based on the determining that the alert is a parent event, determining an object associated with the parent event;
obtaining other events that are associated with the object;
based on the other events that are associated with the object, determining an impact area that the parent event affects; and
based on the determined impact area, performing a topology update for the impact area.
16. The computer readable storage medium of claim 15 , the operations further comprising:
displaying the topology update on a display of a device, wherein the topology update comprises a layer 2 topology or a layer 3 topology.
17. The computer readable storage medium of claim 15 , wherein the impact area comprises a layer 2 area or a layer 3 area.
18. The computer readable storage medium of claim 15 , wherein the object comprises a virtual network device.
