Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If egress peer engineering is implemented to support communication between source and destination, then routing control is improved, but device complexity increases due to additional configuration requirements
Solution Approach 1:
An SDN controller is introduced as an intermediary component that centralizes the configuration and management of egress peer engineering. The controller automatically discovers ingress PE devices, analyzes bandwidth usage, and configures flow rules, eliminating manual configuration complexity while maintaining routing control.
Solution Approach 2:
The system dynamically changes routing parameters based on real-time bandwidth usage analysis. The SDN controller monitors flow statistics and automatically adjusts flow rules to redirect traffic from congested egress peer links to alternative paths, optimizing routing control without requiring manual parameter adjustment.
2Productivity
If manual discovery and management of ingress PE devices is performed, then device complexity is reduced, but productivity decreases due to time-consuming manual processes
Solution Approach 1:
The SDN controller performs automatic self-service discovery of ingress PE devices by analyzing flow statistics and bandwidth usage data from the network. This eliminates manual discovery processes, significantly reducing the time required to identify and manage ingress PE devices while improving overall productivity.
Solution Approach 2:
The system implements continuous feedback loops where the SDN controller monitors network traffic patterns, bandwidth usage, and congestion conditions. This feedback enables automatic updates to flow rules and routing decisions, eliminating manual intervention and accelerating device management processes.
3Loss of information
If traffic is not dynamically redirected, then device complexity is reduced, but loss of information increases due to undetected congestion
Solution Approach 1:
The SDN controller implements continuous feedback monitoring of network traffic by analyzing flow statistics and bandwidth usage on egress peer links. When congestion is detected, the controller automatically generates and applies flow rules to redirect traffic, ensuring congestion information is captured and acted upon without manual intervention.
Solution Approach 2:
Manual monitoring and analysis of network congestion is replaced with automated electronic monitoring systems. The SDN controller uses software-based flow statistics collection and analysis to detect congestion conditions, substituting manual mechanical processes with automated electronic systems that reduce complexity while improving detection capability.
4Productivity
If bandwidth usage is not analyzed, then device complexity is reduced, but productivity decreases due to suboptimal traffic routing
Solution Approach 1:
The SDN controller implements automated feedback-based bandwidth usage analysis by continuously collecting flow statistics from network devices. This analysis informs dynamic routing decisions, optimizing network performance and productivity while the automated nature of the system keeps complexity manageable through centralized control.

AI summary
The present disclosure generally discloses improvements in computer performance in communication networks, which may include improvements in computer performance in supporting discovery of ingress provider edge (PE) devices in a communication network using egress peer engineering (EPE) and software defined networking (SDN). The ingress PE devices of a network may have peering relationships with an egress peer link of an egress peer node of the network. The ingress PE devices may be discovered by identifying a set of traffic flows on an egress peer link of an egress peer node, identifying a set of ingress PE devices that have peering relationships with the egress peer node, determining bandwidth usage information, selecting, from the set of ingress PE devices based on the bandwidth usage information, a set of selected ingress PE devices, and initiating a management action for at least one of the selected ingress PE devices.
