SD-WAN Interconnect Gateway for Multi-Cloud Middle Mile Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current enterprise network architectures do not allow high-speed connectivity access to databases in clouds, leading to challenges in connecting geographically distributed branches to SaaS applications and data warehousing, which hampers user experience and fails to meet Service Level Agreement (SLA) requirements.
Innovation Solution
A software-defined wide area network (SD-WAN) interconnect gateway dynamically discovers and optimizes pathways for branch access to multiple SaaS clouds through middle mile Points of Presence (PoPs), enabling instant, on-demand connectivity by instantiating an interconnect gateway to provide optimized paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If current enterprise network architectures are used, then network infrastructure is maintained, but high-speed connectivity access to databases in clouds is not achieved
Solution Approach 1:
The patent introduces a fabric interconnect gateway as an intermediary device between enterprise network branches and cloud databases. This gateway establishes fabric connections through middle mile network infrastructure, enabling high-speed connectivity without requiring complex changes to existing enterprise network architectures. The gateway acts as a mediator that translates and bridges different network fabrics.
2Adaptability or versatility
If geographically distributed branches connect to centralized cloud applications, then service coverage is expanded, but connectivity performance fails to meet SLA requirements
Solution Approach 1:
The patent segments the network connection path by introducing fabric interconnect gateways at distributed branch locations. Each gateway independently establishes fabric connections to cloud databases, creating multiple segmented connection paths rather than a single centralized connection. This segmentation enables geographically distributed branches to maintain reliable, SLA-compliant connectivity to centralized cloud applications.
3Quantity of substance
If traditional network paths are used for cloud access, then infrastructure simplicity is maintained, but bandwidth and connectivity performance are insufficient
Solution Approach 1:
The fabric interconnect gateway provides multi-functional capabilities by simultaneously supporting traditional network connectivity and fabric-based high-speed connections. The gateway can handle multiple protocols and connection types, enabling enterprises to maintain existing infrastructure while adding enhanced bandwidth capabilities through fabric technology without requiring complete infrastructure replacement.

AI summary
The present technology provides a software-defined wide area network (SD-WAN) interconnect gateway to connect multiple SaaS clouds based on user intent. The technology dynamically discovers the best possible interconnect gateway to provide access to different cloud services from different geographic locations. A first branch connecting to a first cloud, and a second branch connecting to a second cloud, can now share their respective pathways to the clouds so that both branches can enjoy access to both clouds.
