Virtual Cloud Exchange for Managed Layer 3 Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Enterprises face challenges in connecting to multiple clouds via managed networks, as existing solutions often require direct layer 3 provisioning and management by the enterprise, lacking comprehensive security and performance guarantees.
Innovation Solution
The Virtual Cloud Exchange (VCX) provides an all-software approach with Lifecycle Service Orchestrator, Software Defined Networking, and Network Function Virtualization, enabling managed layer 3 services, including Network Address Translation and virtualized security, allowing service providers to manage cloud connectivity and self-provisioning for tenants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If enterprises use managed networks to connect to clouds, then security and performance guarantees are improved, but layer 3 provisioning and management complexity increases for enterprises
Solution Approach 1:
The patent introduces a service provider-managed virtual cloud exchange platform as an intermediary between enterprises and cloud providers. This intermediary handles layer 3 routing, NAT, and security functions, allowing enterprises to connect to multiple clouds through managed networks without directly managing complex layer 3 provisioning. The virtual cloud exchange acts as the mediator that abstracts away the complexity while maintaining security and performance guarantees.
Solution Approach 2:
The patent implements self-service capabilities where the service provider's platform automatically provisions and manages layer 3 services, NAT rules, and security functions without requiring enterprise intervention. The system autonomously handles routing configuration, address translation, and security policy enforcement, reducing the management burden on enterprises while maintaining reliable connections.
2Adaptability or versatility
If enterprises directly manage layer 3 connectivity to clouds, then connectivity flexibility is improved, but operational burden and complexity increases
Solution Approach 1:
The patent creates a universal virtual cloud exchange platform that handles multiple cloud provider connections and various service types through a single managed interface. This multi-functional platform provides adaptability to connect to different cloud providers while maintaining simplified operations through centralized management. The system universally applies NAT, routing, and security functions across all cloud connections without requiring separate enterprise management for each.
Solution Approach 2:
The service provider platform serves as an intermediary that abstracts the complexity of multi-cloud connectivity management. Enterprises gain connectivity flexibility to access multiple cloud providers through this mediator, which handles all operational aspects including routing configuration, address management, and security policies, thereby reducing operational burden while maintaining adaptability.
3Ease of operation
If service providers implement virtual cloud exchange with automated orchestration, then ease of cloud connectivity provisioning is improved, but system complexity increases
Solution Approach 1:
The patent implements self-service automation where the virtual cloud exchange platform autonomously provisions cloud connectivity services. The system automatically performs service deployment, configuration, and management without requiring complex manual intervention from service providers. This automation simplifies the provisioning process for enterprises while the underlying system complexity is managed through automated orchestration of network functions and resources.
Solution Approach 2:
The patent replaces manual mechanical provisioning processes with automated software-based orchestration. Instead of manual configuration and setup, the system uses automated service deployment mechanisms that programmatically establish connections, configure routing, and manage resources. This substitution reduces operational complexity for service providers while maintaining ease of connectivity provisioning for enterprises.
Data Source
AI summary
A Virtual Cloud Exchange (VCX) and method for establishing connectivity between a host computer in a customer network and a cloud service provider, includes a customer facing software defined network (SDN) switch; a cloud computing service facing SDN switch; and a processor executing instructions to generate a customer facing network routing virtual network function (VNF) and a cloud facing network routing VNF; and configure a first open virtual switch (vSwitch) and a second open vSwitch. The customer facing SDN switch generates a first overlay tunnel between the customer facing SDN switch and the first open vSwitch and the cloud facing SDN switch generates a second overlay tunnel between the cloud facing SDN switch and the second open vSwitch.
