NF Entity Routing Bypass for Data Transmission Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network communication processes require extensive hardware and increased load on network function (NF) entities due to the need for identical processing of all data packets, leading to reduced throughput and increased transmission delays.
Innovation Solution
A method where a network function NF entity analyzes data packets and instructs a controller to update routing information, allowing data to be transmitted via a path that does not pass through the NF entity for certain data types, utilizing a fast path offloader to bypass NF entity processing for fast path data packets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all data packets are processed by the NF entity, then data security and control are improved, but transmission delay increases and throughput decreases
Solution Approach 1:
The patent segments data flows into two categories: slow-path data requiring NF entity processing and fast-path data that can bypass the NF entity. This segmentation allows critical data to receive full processing while non-critical data transmits quickly, resolving the contradiction between comprehensive processing and transmission speed.
Solution Approach 2:
The patent introduces a gateway device as an intermediary between the terminal and NF entity. The gateway performs initial data packet analysis and routing decisions, offloading the NF entity from processing all packets while maintaining security control through selective deep packet inspection only when necessary.
2Measurement precision
If all data packets are processed by the NF entity, then data analysis completeness is improved, but network throughput decreases
Solution Approach 1:
The patent applies partial action by performing deep packet inspection only on slow-path data packets that require security analysis, while fast-path packets receive minimal processing. This selective approach maintains analysis completeness for critical data while maximizing overall network throughput.
Solution Approach 2:
The gateway performs preliminary data packet analysis and classification before packets reach the NF entity. By pre-identifying fast-path packets that don't require full processing, the system maintains analysis completeness for necessary packets while improving throughput through early routing decisions.
3Productivity
If specialized hardware is added to support NF entity processing, then data processing capability is improved, but device complexity and cost increase
Solution Approach 1:
The gateway device serves as an intermediary that performs initial packet analysis and routing, reducing the processing burden on the NF entity. This distribution of processing functions improves overall data processing capability without requiring the NF entity to be equipped with extensive specialized hardware for every packet type.
Solution Approach 2:
Fast-path packets are handled automatically by the gateway and routing devices using existing hardware capabilities, without requiring additional specialized processing equipment. This self-service approach for routine packets improves processing capability while avoiding the complexity and cost of adding specialized hardware for all data types.

AI summary
The present invention discloses a data transmission method, device, and system and relates to the field of communications technologies, so that data in a data flow may be transmitted to a destination device according to an actually needed transmission path. The method includes: receiving, by a network function NF entity, first data sent by a terminal device according to first routing information; and instructing, according to a data type of the received first data, a controller device to update the first routing information to second routing information, so that the terminal device sends second data according to the second routing information sent by the controller device, where a data transmission path included in the second routing information does not pass through the NF entity.
