Publication number: 20030138251Abstract: A method, and optical network management system, including detecting, in an electrical domain, a change in performance of an optical transmission system, and determining a cause of the change based on data associated with an optical performance parameter. The data is collected from optical network elements that have a value for the optical performance parameter exceeding a threshold. Another embodiment includes an electrical monitoring device, including outputting an electrical signal that indicates a degradation in the performance, and transmitting a command to the optical network elements to collect the data. A further embodiment includes an optical network element, including transmitting an optical signal to the electronic monitoring point that converts the optical signal to the electrical signal, which is examined to detect the degradation, and transmitting the data to the network management system, if the value exceeds the threshold value.Type: ApplicationFiled: October 11, 2002Publication date: July 24, 2003Inventors: Harish Jayaram, Cengiz Aydin, Curtis Brownmiller, Michael U.

Patent number: 6072777Abstract: A system and method for determining a root cause of error activity in a network is described herein. Root cause analysis includes the correlation between reported error activity for path, line and section entities along a provisioned channel in the network. Root causes can also be identified based upon the correlation of simultaneous error activity on various signal transport levels. Finally, root cause analysis can correlate error activity along various path entities.Type: GrantFiled: June 28, 1996Date of Patent: June 6, 2000Assignee: MCI Communications CorporationInventors: Michael Bencheck, Robert Branton, Curtis Brownmiller, Mark DeMoss, Steve Landon, Minh T.

Patent number: 5913036Abstract: A system and method for analyzing network performance by correlating network performance monitoring data reported by monitoring points in the network is described herein. The system analyzes the performance monitoring parameters by: determining whether the performance monitoring parameters contain non-zero values; determining whether the performance monitoring parameters exceed a predetermined threshold value; determining whether prior performance monitoring parameters exceed a predetermined threshold value. The system initiates a problem handling process if the step of analyzing indicates a possible network problem. The system maintains the problem handling process if the performance monitoring parameters continue to indicate a possible network problem.Type: GrantFiled: June 28, 1996Date of Patent: June 15, 1999Assignee: MCI Communications CorporationInventors: Curtis Brownmiller, Michael Bencheck, Minh T.

Patent number: 5872912Abstract: A system and method for detecting intermittent network performance problems are described herein. The detection process begins upon the receipt of a problem alert signal (PAS). The system then initiates a problem handling process if a predetermined of number of PASs have been received in a predetermined time period prior to receiving the PAS. The system then maintains the problem handling process if additional PASs are received. This system clears the problem and handling processes if no additional PASs are received in a predetermined time period.Type: GrantFiled: June 28, 1996Date of Patent: February 16, 1999Assignee: MCIWORLDCOM, Inc.Inventors: Curtis Brownmiller, Michael Bencheck, Minh T.

Patent number: 5864608Abstract: A system and method for processing performance data in a telecommunication system. The system includes a site controller which is part of an element management layer of a network management hierarchy. Briefly stated, the site controller receives performance data from a network element. The performance data is associated with a plurality of ports of the network element. The network element is part of a network element layer of the network management hierarchy. The site controller selects a first port of the network element to process. The site controller determines whether the first port is cross-connected to a second port of the network element. If the first port is cross-connected to the second port, then the site controller combines performance data associated with the first port and performance data associated with the second port into a performance report. The site controller forwards the performance report to a monitoring module.Type: GrantFiled: June 26, 1996Date of Patent: January 26, 1999Assignee: MCI Communications CorporationInventors: Curtis Brownmiller, Mike Bencheck, Minh Tran, Robert Branton, Mark DeMoss, Steve Landon

Patent number: 5796723Abstract: A system and method for performance monitoring of a telecommunications network that uses a layered performance monitoring structure. First, the monitoring points within the network are identified according to a customer request. The customer request is used to generate a service provisioning request, which indicates the path endpoints and the desired level of service. If the service is a digital data service and is supported for monitoring purposes, the network elements closest to the path endpoints are identified as primary monitoring points and activated, and based upon the desired level of service, a number of intermediate secondary points along the path are also identified but not activated. If the service is not a digital data service but the customer desires monitoring, then monitoring points are similarly identified and activated. Second, an end-to-end threshold is set for each service requiring thresholding per the service provisioning request.Type: GrantFiled: June 28, 1996Date of Patent: August 18, 1998Assignee: MCI Communications CorporationInventors: Michael Bencheck, Robert Branton, Curtis Brownmiller, Mark DeMoss, Steve Landon, Minh T.

Patent number: 5784359Abstract: A system and method for isolating a problem in a network. Upon a report of error activity in a first signal transport level, a first layer in the network management system uses performance data to identify the highest signal transport level that exhibits simultaneous error activity. The first layer attempts to isolate the problem if it determines that it has access to enough information.Type: GrantFiled: June 28, 1996Date of Patent: July 21, 1998Assignee: MCI Communications CorporationInventors: Michael Bencheck, Robert Branton, Curtis Brownmiller, Mark DeMoss, Steve Landon, Minh T.

Patent number: 5778184Abstract: The system and method of analyzing the performance of the network is described herein. The system operates by receiving a first problem alert signal (PAS) from a monitoring point associated with a network facility. The PAS indicates a potential problem with a network facility in a path entity. The system then determines whether the path entity includes distinct line entities. If the path entity includes distinct line entities, then the system determines whether a second problem alert signal has been reported by a monitoring point associated with a network facility in a line entity. The system then initiates a problem handling process for a line entity and suppresses the first PAS if a second PAS has been reported for the line entity. If no problem alert signals have been reported for the line entity, the system initiates a problem handling process for the path entity and reports the first PAS to a higher layer in the network management system.Type: GrantFiled: June 28, 1996Date of Patent: July 7, 1998Assignee: MCI Communications CorporationInventors: Curtis Brownmiller, Michael Bencheck, Minh T.

Patent number: 5768261Abstract: Described herein are a system and method of determining a far-end format of a customer service unit (CSU) operating using an Extended SuperFrame (ESF) framing format. The CSU is in communication with a network element over a DS 1 circuit. The system operates by determining whether any performance data was received from the CSU during a preceding time interval. If no performance data was received from the CSU during the preceding time interval, then the system determines whether the network element is currently configured to operate according to ANSI standard T1.403 or AT&T Recommendation 54016. If the network element is currently configured to operate according to AT&T Recommendation 54016, then the system commands the network element to operate according to ANSI standard T1.403. The system then waits a predetermined time period for receipt of valid performance data conforming to ANSI standard T1.403 from the CSU. If valid performance data conforming to ANSI standard T1.Type: GrantFiled: June 25, 1996Date of Patent: June 16, 1998Assignee: MCI Communications CorporationInventors: Curtis Brownmiller, Mike Bencheck, Minh Tran, Robert Branton, Mark DeMoss, Steve Landon
