Cloud Exchange Point Routing for Branch-to-Cloud Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cloud computing systems face challenges in efficiently routing traffic between cloud nodes, leading to suboptimal performance and increased costs due to inefficient resource utilization and connectivity issues across disparate cloud service providers.
Innovation Solution
The implementation of a cloud node routing system that utilizes a cloud exchange point (CXP) to orchestrate traffic routing between branch networks and cloud services, employing service point attachment nodes (S-nodes) and virtual network facing nodes (V-Nodes) to manage and optimize connectivity and resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cloud traffic is routed through multiple cloud service providers using existing routing methods, then connectivity between cloud nodes is established, but routing efficiency is suboptimal and costs increase
Solution Approach 1:
The patent introduces a cloud exchange point (CXP) as an intermediary routing infrastructure that mediates traffic between cloud service providers. The CXP receives routing information from multiple cloud providers and determines optimal paths, acting as a neutral mediator that improves routing efficiency while reducing costs by avoiding direct peer-to-peer routing through less efficient paths
Solution Approach 2:
The system implements feedback mechanisms where routing information is continuously exchanged between cloud service providers and the CXP. The CXP receives routing information, determines optimal routes based on current network conditions, and provides routing determinations back to the cloud providers, creating a closed-loop feedback system that optimizes routing efficiency and cost
2Adaptability or versatility
If cloud nodes from different service providers interconnect, then connectivity and service diversity are improved, but network complexity and management difficulty increase
Solution Approach 1:
The patent merges the routing intelligence and management functions of multiple cloud service providers into a single centralized cloud exchange point. By combining routing information from various providers and consolidating the routing determination function at the CXP, the system achieves improved connectivity while reducing overall network complexity and management burden
Solution Approach 2:
The cloud exchange point serves as a universal routing infrastructure that handles routing for multiple different cloud service providers simultaneously. The CXP performs multiple functions including receiving routing information from various providers, determining optimal routes across different networks, and providing routing determinations back to the appropriate providers, thereby simplifying the overall system architecture
3Productivity
If routing information is exchanged between cloud service providers, then routing optimization is enabled, but information security and access control become more challenging
Solution Approach 1:
The cloud exchange point acts as a secure intermediary that receives routing information from cloud service providers without requiring the providers to directly share sensitive information. The CXP processes routing determinations based on the received information and returns routing instructions, thereby enabling routing optimization while maintaining information security through the mediator's controlled access architecture
Data Source
AI summary
A router architecture that facilitates cloud exchange point routing is disclosed. The architecture relies upon B-nodes to connect branch network to cloud, S-nodes to connect services, and V-nodes to connect cloud to cloud. The nodes can be essentially stateless with node configuration stored outside a router, which facilitates ripping and replacement of nodes. Multiple virtual private clouds can be implemented with respective pluralities of Kubernetes pods and a master Kubernetes cluster. Consumer premises equipment is coupled to a first virtual private cloud that forms a virtual extensible local area network with a second private cloud.
