Elastic Network Interface Pairing for Direct Cloud Data Forwarding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for interconnecting devices in a cloud environment through virtual private clouds (VPCs) are complex and inefficient, requiring unnecessary VPC functions that consume resources and hinder data forwarding performance.
Innovation Solution
Implementing data transmission using an elastic network interface pair (ENI pair) that is independently deployed in a subnet, allowing direct communication between cloud servers without relying on VPC routes, and utilizing fast channel addressing for data forwarding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If VPC route is used for interconnection between cloud devices, then security isolation and network management are improved, but implementation complexity and data forwarding overhead increase
Solution Approach 1:
The patent extracts the essential data forwarding function from the complex VPC route system. By using elastic network interface pairs with direct address mapping, the solution removes unnecessary VPC routing layers while retaining security through enclave isolation. This extraction principle reduces implementation complexity by focusing only on the core data transmission requirement.
Solution Approach 2:
The patent segments the network interface into paired elastic network interfaces (ENI pairs) that operate independently from the VPC routing system. Each ENI pair is assigned dedicated address mappings, creating isolated transmission channels that bypass the complex VPC route configuration while maintaining security boundaries through enclave separation.
2Adaptability or versatility
If all VPC functions are performed during data transmission, then comprehensive network management is achieved, but data forwarding performance deteriorates
Solution Approach 1:
The patent extracts the data forwarding operation from the full VPC function stack. By using pre-configured ENI pairs with direct address resolution stored in fast channels, the solution performs only the essential forwarding action without invoking broader VPC management functions, thereby improving data forwarding performance while maintaining necessary security controls.
3Reliability
If tunnel establishment is used for data transmission between cloud devices, then secure enclosed communication is achieved, but transmission efficiency and simplicity are reduced
Solution Approach 1:
The patent extracts the security function from the tunnel encapsulation mechanism. By using ENI pairs with direct address mapping and enclave-based isolation, the solution achieves secure communication without the overhead of tunnel establishment and encapsulation/decapsulation operations, thereby improving transmission speed while maintaining security through alternative means.

AI summary
A data transmission method based on a cloud network, a device, and a medium are provided. The method includes: receiving a first data flow transmitted through a first elastic network interface in an elastic network interface pair connected to a first cloud server, in which the elastic network interface pair includes the first elastic network interface and a second elastic network interface, and the first elastic network interface is configured to transmit a data flow to a second cloud server through the second elastic network interface connected to the second cloud server; and when it is determined that the first data flow is transmitted through the elastic network interface pair, querying an address of the second elastic network interface in a fast channel, and forwarding the first data flow to the second cloud server based on the address of the second elastic network interface.
