5G VPC Overlay Routing Between SDDC and Cloud-Native NFs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a limitation in communication within a 5G cloud-native wireless telecommunication network where network functions running on virtual machines in a software-defined data center within a public cloud cannot efficiently communicate with those running on the cloud-native platform of the public cloud due to the absence of a mechanism to route telecommunication network traffic outside the connected virtual private cloud.
Innovation Solution
An overlay network of virtual routers is implemented across the software-defined data center and connected virtual private cloud to enable communication between network functions running on the cloud-native platform and those running on virtual machines, facilitating traffic routing between these environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network functions are distributed across both virtual machines in SDDC and cloud-native platform, then deployment flexibility and agility are improved, but communication efficiency between network functions deteriorates due to absence of routing mechanism
Solution Approach 1:
The patent introduces a gateway as an intermediary component that bridges the SDDC environment and the cloud-native platform. This gateway enables routing of telecommunication network traffic between the two environments, allowing network functions distributed across both platforms to communicate efficiently while maintaining the deployment flexibility benefits of multi-environment distribution.
2Ease of operation
If network functions are deployed on virtual machines in SDDC, then deployment control and management are improved, but network connectivity and traffic routing capability deteriorate due to VPC isolation
Solution Approach 1:
The gateway serves as a mediator that enables the isolated VPC environment to connect with external networks and the cloud-native platform. This allows network functions deployed on virtual machines to maintain both their deployment control advantages and gain the necessary network connectivity for comprehensive communication.
3Reliability
If a connected virtual private cloud is used within public cloud, then security and isolation are improved, but communication capability with external network functions deteriorates due to network isolation
Solution Approach 1:
The gateway acts as a secure intermediary that enables controlled communication between the isolated VPC and external networks. It maintains the security and isolation benefits of the VPC while providing the necessary communication capability to interact with network functions outside the VPC, including those on the cloud-native platform.

AI summary
Example embodiments are directed towards overcoming limitations of a virtual private cloud (VPC) implemented on a public cloud in a cloud-native 5G wireless telecommunication network by overlaying a network of virtual routers (vRouters) across a software defined data center (SDDC) and virtual private cloud (VPC) in such a manner that enables telecommunication network traffic to communicate between one or more telecommunication NFs of the 5G wireless telecommunication network running on a cloud-native platform of the public cloud (e.g., may be workloads that exist in native AWS) and one or more other telecommunication network functions (NFs) of the 5G wireless telecommunication network running in the in the SDDC using the connected VPC (e.g., such as when using VMWare Cloud to implement the SDDC). The connected VPC is a private cloud existing within the public cloud 202 and the overlay network implemented by such vRouters operationally connects the VPC to the host public cloud and other public clouds.
