Container Packet Control Using Stable Application Identifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packet management and control systems face challenges in managing and controlling containers due to dynamic IP address changes, leading to high management and control complexity.
Innovation Solution
Implementing a packet management and control method that uses an identifier of the application deployed in a container, such as an APN header or TCP header, to manage and control packets, rather than relying on the container's IP address, which remains stable during online/offline and migration events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If packet management is based on container IP address, then packet control can be implemented, but management complexity increases due to dynamic IP changes
Solution Approach 1:
The patent introduces an application identifier as an intermediary element that mediates between the container and the packet management system. Instead of directly using the container's dynamic IP address, the system uses the application identifier (which remains constant) as a stable reference point. This intermediary resolves the contradiction by providing a consistent identification mechanism that simplifies management while maintaining control capabilities despite IP address changes.
2Reliability
If container IP address is used for packet identification, then network routing is enabled, but identification reliability decreases due to IP address changes during migration
Solution Approach 1:
The patent segments the identification function into two parts: the container identifier (which remains constant and provides reliability) and the network address (which can change and provides adaptability). By separating these functions, the system maintains reliable packet identification through the stable application identifier while still supporting container mobility and network routing through the flexible IP address mechanism.
