METHOD AND APPARATUS FOR OUTAGE MEASUREMENT
First Claim
Patent Images
1. An apparatus, comprising:
- one or more processors;
a memory coupled to the processors comprising instructions executable by the processors, the processors operable when executing the instructions to;
monitor for outages occurring locally at a network device that is a single-point-of-failure for one or more remote endpoints that send communications from a first private network, through the network device, to a second network;
monitor for outages occurring remotely on first network links that connect the remote endpoints to the network device;
identify outage information according to the local and remote monitoring; and
send the outage information from the network device, over the second network to a remote system that is located outside the first private network and that monitors for outages located on remote links located in the second network.

Abstract
An Outage Measurement System (OMS) monitors and measures outage data at a network processing device. The outage data can be stored in the device and transferred to a Network Management System (NMS) or other correlation tool for deriving outage information. The OMS automates the outage measurement process and is more accurate, efficient and cost effective than previous outage measurement systems.

9. An apparatus comprising:
-
one or more processors;
a memory coupled to the processors comprising instructions executable by the processors, the processors operable when executing the instructions to;
exchange communications with a remote network device that forwards messages generated by one or more remote endpoints located in a private network through the remote network device and to a publicly accessible network;
receive outage information generated by the remote network device, the received outage information corresponding to the remote network device and to private network links that connect the remote endpoints to the remote network device;
compare the received outage information to local outage information that corresponds to other network links for connecting the remote endpoints to the publicly accessible network, the local outage information generated independently from monitoring performed by the remote network device; and
identify failures on the private network links, the remote network device and the other network links according to the comparison such that outages affecting Internet accessibility for the remote endpoints are identified. - View Dependent Claims (10, 11, 12, 13, 14)

15. An apparatus, comprising:
-
one or more processors;
a memory coupled to the processors comprising instructions executable by the processors, the processors operable when executing the instructions to;
monitor for outages occurring locally at a network device that provides publicly accessible network access for one or more remote endpoints by transferring communications sent over a first private network by the remote endpoints to a second network;
monitor for outages occurring between the network device and the remote endpoints;
identify first outage information according to the local and remote monitoring; and
send the first outage information from the network device to a remote system that is located outside the first private network for combining with remotely-generated second outage information that identifies outages occurring between the network device and the publicly accessible network. - View Dependent Claims (16, 17, 18, 19, 20)
