Ethernet Protocol Translation Gateway for QoS Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IP-based networks face challenges in providing guaranteed Quality of Service (QoS) for multimedia services like video communication due to packet loss and error codes, with existing solutions like Inte Serv, Diff Serv, and Light load failing to effectively manage network congestion and flow non-uniformity.
Innovation Solution
An Ethernet-compatible data transmission method and protocol translation gateway that uses a centralized control function to manage MAC addresses and flow control, ensuring compatibility between Ethernet and novel networks by adding or removing MAC addresses from data packets, and implementing precise flow control to optimize data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If IP-based packet switching is used for network transmission, then network flexibility and scalability are improved, but Quality of Service (QoS) guarantee deteriorates due to packet loss and error codes
Solution Approach 1:
The patent introduces an intermediary mechanism (QoS management system with centralized control) that mediates between IP packet switching and QoS requirements. This intermediary monitors network conditions, manages packet flow, and ensures QoS guarantees while maintaining the flexibility of IP-based transmission.
2Reliability
If Inte Serv, Diff Serv, or Light load solutions are implemented to manage network congestion, then QoS management capability is improved, but device complexity and implementation difficulty worsen
Solution Approach 1:
The patent creates a universal QoS management system that can handle multiple service types and network conditions through a single centralized platform. This multi-functional system reduces implementation complexity by providing unified management rather than separate solutions for different scenarios.
Solution Approach 2:
The patent implements feedback mechanisms where the centralized QoS management system continuously monitors network conditions, packet flow, and QoS metrics, then adjusts transmission parameters dynamically. This closed-loop control simplifies management by automatically responding to changing conditions without manual intervention.
3Ease of operation
If flow non-uniformity is not managed, then network operation simplicity is maintained, but packet loss and transmission quality worsen
Solution Approach 1:
The patent enables the network system to self-regulate flow uniformity through automated QoS management. The centralized system automatically detects and corrects flow non-uniformity without requiring manual network operations, maintaining simplicity while improving transmission quality through intelligent self-management.

AI summary
A new type of network is a network with centralized control function. An Ethernet protocol translation gateway can access the network and obtain from a node server therein MAC address of the Ethernet protocol translation gateway and the MAC address of terminals bound to the Ethernet protocol translation gateway. A data packet to be transmitted from the network to the Ethernet can be forwarded to a target terminal in the Ethernet according to the MACs of the terminals, by adding the MAC of the Ethernet protocol translation gateway and the MAC of the target terminal to the packet. For a data packet transmitted from the Ethernet to the network, the packet can be forwarded to the network according to the destination address of the network in the packet by means of removing from the packet the MAC of the Ethernet protocol translation gateway and the MAC of the target terminal.
