Routing Master Controller Policy Integration for Network Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In computer networks, the lack of interaction between security/control servers and routing master controllers (RMCs) leads to inefficient routing optimization and potential policy conflicts, as the RMC has no knowledge of control server traffic policies, resulting in suboptimal path determination and resource allocation.
Innovation Solution
Transmitting control policies from the security/control server to the RMC, which integrates them with traffic policies to generate a set of integrated policies, allowing the RMC to classify traffic classes and notify routers for optimal path routing, thereby resolving policy conflicts and enhancing network resource management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If control policies are kept separate at the security server without transmission to the RMC, then the security server maintains independent policy control, but the RMC cannot optimize routing paths based on security policies and policy conflicts may arise
Solution Approach 1:
The patent introduces a policy integration mechanism that acts as an intermediary between the security server and RMC. The security server transmits control policies to the RMC, which then integrates them with traffic policies to generate unified routing decisions. This intermediary integration process resolves the contradiction by enabling routing optimization based on security policies while maintaining a structured policy management framework.
Solution Approach 2:
The patent merges separate control policies from the security server with traffic policies at the RMC to create integrated routing policies. By combining these previously separate policy sets, the system achieves unified optimization that considers both security requirements and routing efficiency, directly improving productivity while managing complexity through systematic integration.
2Reliability
If the RMC determines optimal paths without knowledge of control server policies, then routing decisions are made independently and quickly, but the paths may not align with security priorities and conflicts occur
Solution Approach 1:
The security server proactively transmits control policies to the RMC in advance, enabling the RMC to have policy knowledge available before making routing decisions. This preliminary action ensures that when routing decisions are made, they can immediately align with security priorities without requiring real-time policy retrieval, thus maintaining quick decision-making while improving policy alignment reliability.
Solution Approach 2:
The system establishes a feedback mechanism where the RMC receives control policies from the security server and integrates them into routing decisions. This feedback loop ensures that routing decisions continuously align with security policies, improving reliability while the automated nature of the feedback minimizes time loss compared to manual coordination.
3Ease of operation
If manual configuration is used to share policies between security server and RMC, then policy consistency can be achieved, but the process becomes cumbersome and inefficient
Solution Approach 1:
The system implements automated policy transmission from the security server to the RMC, eliminating the need for manual configuration. The security server automatically shares control policies with the RMC, which then self-integrates them with traffic policies. This self-service approach dramatically improves ease of operation while maintaining high productivity, as the automated processes handle policy synchronization without human intervention.

AI summary
In one embodiment, a first set of one or more control policies at a control server of a network domain may be transmitted to a routing master controller of the network domain, which uses a second set of one or more traffic policies to determine optimal paths for directing traffic through the domain. The routing master controller may then generate a third set of one or more integrated policies based on the first and second sets of policies, e.g., based on the knowledge and policies of both the control server and the routing master controller.
