Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network communication technologies face inefficiencies in packet forwarding between networks using different internet communication protocols, such as IPv4 and IPv6, due to the need for extensive processing like filtering, routing, and firewall testing, which slows down the forwarding process.
Innovation Solution
A network device with a packaging module, determining module, and adding module processes packets by packaging second network information into the packet header, determining and adding transport layer protocol information, and forwarding the packet efficiently, allowing for fast-forwarding when applicable, thereby improving forwarding efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If packets are processed with filtering, routing, and firewall testing in the second network, then network security and routing accuracy are improved, but packet forwarding speed deteriorates
Solution Approach 1:
The patent applies preliminary action by performing packaging of second network information and addition of transport layer protocol information in the first network before packet forwarding. This preprocessing enables the second network to directly forward packets without performing filtering, routing, and firewall testing, thus achieving fast forwarding while maintaining network security through advance preparation of necessary network information.
Solution Approach 2:
The patent introduces an intermediary mechanism by adding transport layer protocol information as a mediator between the first network and second network. This intermediary information allows the second network to identify and fast-forward packets without performing extensive security checks, resolving the contradiction between security verification and forwarding speed.
2Manufacturing precision
If extensive processing like filtering, routing, and firewall testing is performed, then packet forwarding accuracy is improved, but processing time increases
Solution Approach 1:
The patent performs preliminary packaging of second network information and addition of transport layer protocol information before packet forwarding. This advance preparation ensures that all necessary routing and identification information is embedded in the packet, allowing the second network to forward packets accurately without performing time-consuming filtering, routing, and firewall testing operations.
Solution Approach 2:
The patent extracts essential second network information and transport layer protocol information from the complex processing operations and embeds them directly into the packet header. This extraction eliminates the need for the second network to perform extensive processing, thereby reducing processing time while maintaining forwarding accuracy through the embedded information.
3Adaptability or versatility
If packets are forwarded between networks with different internet communication protocols, then network compatibility is improved, but forwarding efficiency deteriorates
Solution Approach 1:
The patent introduces second network information and transport layer protocol information as intermediaries between networks with different internet communication protocols (e.g., IPv4 and IPv6). These intermediary elements enable protocol translation and compatibility without requiring extensive processing at the receiving end, thus maintaining network compatibility while improving forwarding efficiency through fast forwarding.
Solution Approach 2:
The patent changes packet parameters by packaging second network information and adding transport layer protocol information in the first network. This parameter transformation enables packets to be compatible with different network protocols while allowing the second network to efficiently identify and fast-forward packets without performing protocol conversion processing, thereby resolving the contradiction between compatibility and efficiency.
Data Source
AI summary
A method for data processing is executable by a network device. The network device is configured to forward a packet in a network to another network. Before forwarding the packet to the other network, the network device adds corresponding destination information address and transport layer protocol information into a header of the packet. The packet will be fast forwarded in subsequent networks or network devices, thereby saving forwarding time and improving forwarding efficiency.
