Gateway Access Control List for Unwanted Packet Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Restricted bandwidth networks experience performance degradation and user experience issues due to unwanted data packets originating from other networks, leading to error messages and increased bandwidth usage, which are not effectively managed by existing technologies.
Innovation Solution
A method and system that utilize a gateway, such as a home agent, to monitor error messages and create access control lists to block unwanted data packets based on source and destination identification, preventing them from entering the restricted bandwidth network by establishing thresholds and conditions for list creation and elimination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If unwanted data packets are blocked at the gateway, then bandwidth consumption and error messages are reduced, but network complexity increases due to access control list management
Solution Approach 1:
The gateway automatically monitors error messages, detects patterns, creates access control lists, and manages their expiration without manual intervention. The system serves itself by autonomously identifying unwanted packets and implementing blocking rules based on observed error message patterns.
Solution Approach 2:
The system dynamically adjusts network parameters by creating and modifying access control lists based on real-time error message analysis. When threshold conditions are met, the gateway changes packet filtering parameters to block identified unwanted traffic patterns.
2Reliability
If access control lists are created and maintained, then packet blocking effectiveness improves, but processing time and computational resources increase
Solution Approach 1:
The gateway proactively monitors error messages and pre-creates access control lists before unwanted packets cause significant disruption. By detecting patterns early and establishing blocking rules in advance, the system prevents future packet processing delays.
Solution Approach 2:
The system uses threshold-based activation to avoid processing every possible packet pattern. Only when error messages exceed a defined threshold does the gateway create blocking lists, allowing it to ignore benign traffic variations while acting only when necessary.
3Measurement precision
If error messages are monitored continuously, then unwanted packet identification accuracy improves, but network bandwidth and processing load increase
Solution Approach 1:
The gateway extracts and analyzes only the critical identification fields from error messages (source IP, destination IP, protocol information) rather than processing entire packet payloads. This selective extraction maintains identification accuracy while minimizing bandwidth consumption for monitoring.
Solution Approach 2:
The system uses error messages as feedback signals to automatically adjust packet filtering behavior. By continuously monitoring error patterns and using them to refine access control lists, the gateway improves identification accuracy over time while adapting to changing network conditions.
Data Source
AI summary
Systems, methods, and computer-readable media for eliminating unwanted data packets by a restricted bandwidth network that interfaces with a second network are provided. In embodiments, a device receives unwanted data packets associated with identification of the device. Due to the transient nature of some forms of device identification, data packets intended for one user may be received by another user who has taken on the device identification of the first user. To remedy this situation, unwanted data packets are identified and blocked at a gateway based on the source and/or destination identification associated with the data packets.
