Dynamic Traffic Prioritization Across Data Center VPNs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques lack a mechanism to intelligently adjudicate bandwidth disputes between different types of traffic transmitted over virtual private networks (VPNs) between data centers, leading to congestion and oversaturation issues.
Innovation Solution
Implementing traffic prioritization policies that are user-defined or system-generated based on network conditions, allowing for the distribution and enforcement of quality of service (QoS) across data centers to ensure high-priority traffic is favored during bandwidth conflicts, using centrally-managed virtual switches and configuration agents to manage bandwidth allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of traffic are transmitted over L2VPN between data centers, then network connectivity and service diversity are improved, but bandwidth conflicts and network congestion occur due to insufficient available bandwidth
Solution Approach 1:
The patent implements traffic prioritization by assigning different priority levels to different types of traffic (management traffic, infrastructure traffic, application traffic, site recovery traffic, hybrid cloud extension traffic, workload traffic, service insertion traffic, VCI migration traffic). This allows critical traffic to receive preferential treatment during bandwidth conflicts, ensuring reliable transmission of high-priority traffic while maintaining diverse service support.
Solution Approach 2:
The system dynamically changes the parameter of traffic priority assignment based on traffic type and network conditions. By modifying the priority parameter for different traffic categories, the system resolves bandwidth conflicts intelligently, allowing adaptive bandwidth allocation that maintains both service diversity and reliability.
2Device complexity
If bandwidth allocation is managed without traffic prioritization, then network simplicity is maintained, but intelligent adjudication of bandwidth disputes cannot be achieved leading to congestion
Solution Approach 1:
The patent implements dynamic traffic prioritization where priority assignments can be adjusted based on network conditions and traffic requirements. Configuration agents can update priority policies dynamically, allowing the system to adapt to changing bandwidth demands and resolve conflicts efficiently without requiring complex manual intervention, thus maintaining operational simplicity while improving bandwidth utilization.
Solution Approach 2:
The system employs configuration agents that automatically manage bandwidth allocation and priority assignments based on predefined policies and current network conditions. This self-service mechanism intelligently adjudicates bandwidth disputes without requiring manual network administrator intervention for each conflict, maintaining simplicity while achieving high bandwidth utilization efficiency through automated priority-based arbitration.
