Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing server virtualization and zone clustering technologies face challenges in providing reliable and secure networking support for applications, particularly in ensuring predictable throughput and fault tolerance during application migrations between zone entities.
Innovation Solution
Implementing an exclusive TCP/IP stack for each zone entity within a server system, allowing applications to maintain communication using dedicated resources, ensuring predictable performance and security, and enabling seamless migration between zone entities while maintaining isolation from other entities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If shared networking resources are used among multiple zone entities, then device complexity is reduced, but network communication security and reliability deteriorate
Solution Approach 1:
The patent segments the shared networking infrastructure into multiple virtual network stacks, with each zone entity having its own dedicated virtual network stack. This segmentation isolates network communication paths while maintaining physical resource sharing, thereby improving reliability without requiring separate physical hardware for each zone entity.
2Productivity
If shared networking resources are used among multiple zone entities, then resource utilization efficiency is improved, but network communication security deteriorates
Solution Approach 1:
The patent implements segmentation by creating separate virtual network stacks for each zone entity, ensuring that network traffic is isolated at the software layer. This allows efficient sharing of physical networking resources while maintaining security through virtualization-based isolation boundaries.
Solution Approach 2:
The virtual network stack acts as an intermediary layer between the physical networking infrastructure and zone entities. This intermediary provides controlled access and isolation, enabling secure resource sharing by mediating all network communications through dedicated virtual paths.
3Reliability
If application migration between zone entities is implemented, then system fault tolerance is improved, but network communication continuity becomes challenging
Solution Approach 1:
The patent prepares network communication continuity in advance by assigning dedicated virtual network stacks to each zone entity before migration occurs. When application migration is needed for fault tolerance, the pre-configured virtual network infrastructure is already in place to immediately support the migrated application, ensuring communication stability throughout the migration process.

AI summary
An aspect of the present invention provides a corresponding exclusive communication stack (e.g., TCP/IP stack) for each zone entity of a server system. In an embodiment, multiple server systems together implement a zone cluster containing such zone entities provided on corresponding server systems. As a result, when an application executing on a first zone entity of a first server is moved to a second zone entity of a zone cluster on a second server, the application continues to communicate using exclusive communication stack provided for the second zone entity. In view of the dedicated resources for network communication, applications executing in any zone entity of such a zone cluster, may have a desired level of predictable throughput performance and security for the communicated data packets.
