DSLAM Automatic Data Flow Mapping via Self-Service Correlation

Solution Overview

Problem

The manual configuration of DSLAM ports by operators at central offices is required to establish data flow between CPE and DSLAM, which is time-consuming and costly, and does not efficiently update old data mapping information.

Innovation Solution

A method for automatically mapping data flow by correlating PVC identifiers and MAC addresses using a database within the DSLAM, allowing the system to automatically determine and update data paths without manual intervention.

1Reliability

If manual configuration of DSLAM ports by operators is used, then data flow mapping can be established, but the process is time-consuming and costly

Engineering Contradiction:

Improvedata flow mapping accuracyVSAvoidservice initiation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The DSLAM system automatically performs data flow mapping by receiving data cells from CPE, extracting path and party information, and correlating them in its database without requiring operator intervention. The system serves itself by autonomously updating mapping information when changes occur.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The CPE is pre-programmed with PVC identifiers and MAC addresses before service initiation. This preliminary configuration enables the automatic mapping process at the DSLAM to function correctly without requiring manual setup at the central office.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If manual configuration of DSLAM ports is used, then data flow mapping can be established, but the cost of initiating service increases

Engineering Contradiction:

Improvedata flow mapping accuracyVSAvoidservice initiation cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The DSLAM system automatically performs data flow mapping by receiving data cells from CPE, extracting path and party information, and correlating them in its database without requiring operator intervention. The system serves itself by autonomously updating mapping information when changes occur.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical process of operator configuration is replaced with an automated electronic system that uses data cell analysis and database correlation to perform mapping, eliminating the need for physical operator intervention at the central office.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If manual configuration is used, then initial data mapping can be established, but old data mapping information cannot be efficiently updated

Engineering Contradiction:

Improvedata mapping accuracyVSAvoiddata mapping update efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system continuously monitors incoming data cells and automatically detects changes in path-party correlations. When changes are detected, the DSLAM updates its database accordingly, creating a feedback loop that maintains current mapping information without manual intervention.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The DSLAM system automatically performs data flow mapping by receiving data cells from CPE, extracting path and party information, and correlating them in its database without requiring operator intervention. The system serves itself by autonomously updating mapping information when changes occur.

Inventive Principle:

Principle #25Self-service

AI summary

According to one embodiment of the invention, a method for automatically mapping data flow is provided. The method includes receiving, over a path and at a digital subscriber line access multiplexer, a data cell from a party. The digital subscriber line access multiplexer has a database. The method also includes identifying the path and the party from the data cell. The method also includes determining that the database does not correlate the path and the party. The method also includes correlating the party with the path in the database in response to determining that the database does not correlate the path and the party.
