Method and apparatus for monitoring and displaying routing metrics of a network
View Patent ↗The invention includes an apparatus and method for displaying path metrics associate with nodes and links within a network. The method includes determining path metric values associated with the network. The method further includes displaying only the path metric values that fall within a predetermined set. The predetermined set can be adjustable by a network manager. The predetermined set can include an initial default value and be additionally adjusted by a network manager. The predetermined set associated with a particular node can be based upon a redundancy of paths available to the particular node.
1. A method of displaying path metrics associate with nodes and links within a wireless mesh network, comprising:
determining path metric values associated with the wireless mesh network, wherein the path metric values provide an indication of a transmission link qualities and path qualities; wherein determining path metric values comprises;
gateways of the network originating routing beacons;
access nodes receiving and monitoring the routing beacons, the access nodes determining a link quality and path quality associated with the received routing beacons based on the routing beacons, the access nodes retransmitting modified routing beacons if the path quality is above a threshold;
a network management system receiving the transmission link qualities and the transmission path qualities from each of the access nodes;
visually displaying on a display of the network management system observable by a network manager, only the path metric values that fall within a predetermined range, wherein the predetermined range is adjustable.
2. The method of claim 1 , wherein the predetermined range comprises values greater than a threshold value.
3. The method of claim 1 , wherein the predetermined range is adjustable by a network manager.
4. The method of claim 1 , wherein the predetermined range comprises an initial default value, wherein the predetermined range can be additionally adjusted by a network manager.
5. The method of claim 1 , wherein the predetermined range associated with a particular node is based upon a redundancy of paths available to the particular node.
6. The method of claim 5 , wherein the redundancy of paths of a node is determined by a number of paths associated with the node that have path metric values that fall within the predetermined range.
7. The method of claim 1 , wherein each node of the network includes a node predetermined range that can be individually adjusted for each node.
8. The method of claim 7 , wherein a network manager can adjust each of the node predetermined ranges.
9. The method of claim 7 , wherein each node predetermined range is at least partially dependent upon a use of a corresponding node.
10. The method of claim 1 , further comprising displaying representation of a redundancy of paths associated each node.
11. The method of claim 10 , wherein only nodes having a threshold number of redundant paths are distinguishably displayed.
12. The method of claim 1 , wherein determining path metric values associated with the network comprises determining a success ratio of a number of routing beacons successfully received at a node, versus a number of transmitted routing beacons over a period of time T 1 , for each wireless route to each node.
13. The method of claim 12 , wherein determining path metric values associated with the network further comprises determining a success long ratio of a number of routing beacons successfully received by a node versus a number of transmitted routing beacons over a period of time T 2 , wherein T 2 is substantially greater than T 1 , for each node.
14. The method of claim 1 , wherein determining path metric values associated with each node of the network further comprises determining a throughput, for each node.
15. The method of claim 1 , wherein determining path metric values comprises determining a variability of each path.
16. The method of claim 1 , further comprising providing suggestions to a network manager of better locations of the nodes to improve performance of the network.
17. The method of claim 16 , wherein providing suggestions to the network manager of better locations of the nodes to improve performance of the network comprises recommending nodes that include a poor link be moved closer to each other.
18. The method of claim 1 , further comprising providing suggestions to a network manager of new locations of additional nodes to improve performance of the network.
19. The method of claim 18 , wherein providing suggestions to the network manager of new locations of additional nodes to improve performance of the network comprises recommending additional nodes between nodes that include a poor link.
