Benefits of technology

This approach allows network operators to detect and address potential service disruptions proactively by identifying deviations from historical norms, ensuring timely intervention and maintaining network health.

Problems solved by technology

In communication networks, customer impacting disruptions sometimes occur.
Most of these disruptions produce alarms that allow network operators to quickly restore service.
Occasionally, however, defects in the network occur and are masked as normal events.

Embodiment Construction

[0012]To better understand the present invention, FIG. 1 illustrates an example network, e.g., a packet-switched network such as a VoIP network related to the present invention. The VoIP network may comprise various types of customer endpoint devices connected via various types of access networks to a carrier (a service provider) VoIP core infrastructure over an Internet Protocol / Multi-Protocol Label Switching (IP / MPLS) based core backbone network. Broadly defined, a VoIP network is a network that is capable of carrying voice signals as packetized data over an IP network. An IP network is broadly defined as a network that uses Internet Protocol to exchange data packets.

[0013]The customer endpoint devices can be either Time Division Multiplexing (TDM) based or IP based. TDM based customer endpoint devices 122, 123, 134, and 135 typically comprise of TDM phones or Private Branch Exchange (PBX). IP based customer endpoint devices 144 and 145 typically comprise IP phones or PBX. The Ter...

Abstract

The present invention enables the network to determine the true state of events that appear normal but produce service disruptions by periodically probing the status of all network elements and endpoints and comparing this status to historical graphs of the network. Events that deviate from a historical view will be alarmed to determine their true status.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of co-pending U.S. patent application Ser. No. 11 / 049,383, filed Feb. 2, 2005, entitled, “METHOD AND APPARATUS FOR ENABLING THE DETECTION OF TRANSPARENT DEFECTS”, which has been allowed. The aforementioned related patent application is herein incorporated by reference.BACKGROUND OF THE INVENTION[0002]In communication networks, customer impacting disruptions sometimes occur. Most of these disruptions produce alarms that allow network operators to quickly restore service. Occasionally, however, defects in the network occur and are masked as normal events. For example sometimes the network fails to detect the active status of an endpoint connected to it and sends a call destined to that endpoint directly to voicemail. This event occurs because of a miscommunication between the endpoint and the network and not because the endpoint is truly unavailable. Since the network is temporarily blind to the true statu...
