Cloud S2C Resources for Service-to-Customer Network Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cloud infrastructure systems face challenges in enabling secure and efficient data exchange between private networks of service providers and customers when IP address ranges overlap or private IP addresses are used, leading to issues in packet routing and communication.
Innovation Solution
The implementation of S2C resources on a cloud infrastructure that translate IP addresses and provide virtual network interface cards (VNICs) to facilitate data exchange between private networks, ensuring proper processing and communication despite overlapping IP address ranges or unique private IP addresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If private networks use overlapping IP address ranges or private IP addresses, then network isolation and security are maintained, but packet routing and communication between networks fail
Solution Approach 1:
The patent introduces S2C resources as intermediary components that sit between private networks with overlapping IP address ranges. These S2C resources perform IP address translation, converting addresses from one private network's range to another's, thereby enabling communication while maintaining the original network isolation and security boundaries. The intermediary resolves the routing conflict without requiring changes to the private networks themselves.
Solution Approach 2:
The patent applies parameter changes by dynamically translating IP address parameters between different private networks. The S2C resources modify the IP address parameter of packets as they traverse between networks with overlapping address ranges, allowing each network to maintain its own addressing scheme while enabling successful inter-network communication through controlled parameter transformation.
2Reliability
If cloud infrastructure provides isolated private networks for service providers and customers, then security and control are enhanced, but direct data exchange between networks becomes impossible
Solution Approach 1:
The S2C resources function as secure intermediaries that enable controlled data exchange between isolated private networks. They maintain the security boundaries by requiring explicit configuration and authorization for cross-network communication, while simultaneously providing efficient data transfer capabilities through optimized IP address translation and packet forwarding mechanisms.
Solution Approach 2:
The patent segments the network communication function into distinct components: the isolated private networks maintain their security boundaries, while the S2C resources provide a separate, dedicated translation and forwarding layer. This segmentation allows each network to operate independently with full security isolation, while the intermediary segment handles all cross-network communication needs efficiently.
3Adaptability or versatility
If IP address translation is implemented between private networks, then communication compatibility is achieved, but network complexity and configuration overhead increase
Solution Approach 1:
The S2C resources are designed as universal, multi-functional components that handle multiple private network configurations simultaneously. A single S2C resource can translate between multiple different IP address ranges and support multiple customer-provider network pairs, reducing overall system complexity compared to having dedicated translation devices for each network pair.
Solution Approach 2:
The patent implements self-service capabilities where the S2C resources automatically perform IP address translation based on configured routing rules without requiring manual intervention for each translation operation. The system self-manages the complexity of maintaining translation tables and routing information, reducing the operational burden on network administrators.

AI summary
Techniques for providing, to a resource on a private network of a service provider, access to a resource on a private network of a customer. Service to customer (S2C) resources deployed on a cloud infrastructure to facilitate the access. Whereas IP address ranges may overlap between private networks and/or private IP addresses may be used in one or more of the private networks, the S2C resources enable the data exchange between the private networks. For example, the S2C resources translate between IP addresses such that data within each private network uses IP addresses that can be properly processed by the private network.
