Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network systems cannot efficiently support applications that require dynamic port assignment, especially in cluster environments with restricted user rights, as traditional port forwarding methods require static configurations and are not accessible from outside the cluster.
Innovation Solution
The method involves creating an IP tunnel between networks using a tunnel client and server node, with the server node operating in promiscuous mode to capture and forward Ethernet frames, allowing dynamic port access without requiring user rights to create virtual network interfaces, enabling communication through existing IP tunnel implementations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a host computer in an IP network is connected to a storage device via a Fibre Channel network, then high-speed data transfer is achieved, but the host computer cannot be managed by standard IP network management tools
Solution Approach 1:
A gateway device is introduced as an intermediary between the Fibre Channel network and IP network. The gateway translates Fibre Channel protocols into IP protocols, enabling storage devices to be accessed and managed through standard IP network management tools while maintaining high-speed data transfer capabilities through the Fibre Channel connection.
Solution Approach 2:
The gateway device performs multiple functions: it acts as a protocol translator between Fibre Channel and IP networks, provides network management capabilities for storage devices, and enables both high-speed data transfer and standard IP-based management. This multi-functionality resolves the contradiction by making the system adaptable to different operational requirements.
2Speed
If storage devices are connected via Fibre Channel network, then high-speed access is achieved, but integration with IP network management infrastructure is lost
Solution Approach 1:
The gateway serves as a mediator that connects the Fibre Channel storage network to the IP network infrastructure. It translates storage device communications into IP-compatible protocols, allowing seamless integration with existing IP network management tools and infrastructure while preserving high-speed access through the Fibre Channel connection.
Solution Approach 2:
The gateway changes protocol parameters and communication methods to bridge between Fibre Channel and IP networks. By transforming data formats, addressing schemes, and communication protocols, it enables storage devices to participate in IP network infrastructure while maintaining their high-speed Fibre Channel connections.
3Speed
If separate Fibre Channel network is used for storage, then high-speed data transfer is maintained, but network complexity increases
Solution Approach 1:
The gateway merges the Fibre Channel storage network and IP network into a unified communication infrastructure. By providing protocol translation and interoperability, it allows both networks to coexist and communicate through a single gateway device, reducing the need for completely separate network infrastructures while maintaining high-speed data transfer capabilities.
