Network Traffic Control via Centralized Decision Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems cannot effectively manage service traffic across multiple network elements, leading to resource overload and potential system breakdowns, as they primarily focus on individual network element traffic management.
Innovation Solution
The system is divided into a service sampling network element, a decision network element, and an execution network element, which work together to sample traffic and load information, determine processing policies, and execute traffic control decisions across multiple network elements, enabling coordinated traffic management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a service access network element performs traffic control based on local traffic information and load information, then the resource overload problem of the service processing network element is resolved, but the network element can only perform traffic management on its own service and cannot coordinate with multiple network elements
Solution Approach 1:
The patent introduces a service management network element as an intermediary that collects traffic information from multiple service access network elements and load information from service processing network elements. This mediator coordinates traffic control decisions across the entire network, enabling unified traffic management while preventing resource overload at any single processing node.
Solution Approach 2:
The service management network element performs multiple functions: collecting traffic information from service access network elements, obtaining load information from service processing network elements, determining traffic control decisions, and distributing control information back to access elements. This multi-functional approach enables coordinated traffic management across multiple network elements through a single centralized entity.
2Adaptability or versatility
If a centralized service management network element collects traffic information from multiple service access network elements and coordinates traffic control, then traffic management across multiple network elements is achieved, but the system complexity increases
Solution Approach 1:
The patent segments the traffic management system into distinct functional components: service access network elements that collect local traffic information, service processing network elements that provide load information, and a service management network element that performs centralized decision-making. This segmentation allows each component to have a specific, simplified function while achieving complex coordinated management through their interaction.

AI summary
The present invention relates to the communications field, and specifically, to a service traffic control method, a decision network element, and a communications system. In the communications system, a resource sampling network element obtains reference load information of a service resource of the resource sampling network element and sends the reference load information to a decision network element; a service sampling network element obtains reference traffic information and sends the reference traffic information to the decision network element; according to the reference load information and the reference traffic information, the decision network element determines target traffic control information and sends the target traffic control information to an execution network element, where the target traffic control information is used to indicate a processing policy of a request of a target service; and the execution network element executes, for the target service, the processing policy of the service request of the target service according to the target traffic control information. According to solutions provided in this application, a decision network element can perform traffic management on services of multiple service sampling network elements.
