Dynamic Priority Bandwidth Reservation for Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional network resource management systems lack a mechanism to dynamically prioritize user connections, leading to situations where high-priority users, such as instructors or webinar hosts, may be unable to access network resources due to limited bandwidth and poor connectivity caused by a large number of concurrent users, especially in environments with finite network resources.
Innovation Solution
A method and system that identifies high-priority clients based on predefined roles or policies, reserves bandwidth for these clients, and restricts usage by other clients to ensure high-priority users have guaranteed access to network resources, using a network controller to manage access points and client devices, caching device priority information, and dynamically prioritizing traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bandwidth is shared equally among all users, then network resource utilization is maximized, but high-priority users suffer from poor connectivity and unreliable access
Solution Approach 1:
The patent implements differentiated quality of service by assigning different priority levels to different users based on their roles. High-priority users (e.g., instructors) receive guaranteed bandwidth and preferential treatment, while low-priority users (e.g., students) receive remaining capacity. This local differentiation resolves the contradiction by ensuring reliable access for critical users while maintaining overall system efficiency.
Solution Approach 2:
The system performs preliminary classification of users into priority groups before network access is needed. By pre-identifying high-priority users and reserving bandwidth for them in advance, the system ensures their reliable access without compromising overall network utilization when such users are actively transmitting data.
2Reliability
If access points serve maximum number of concurrent users, then network capacity is fully utilized, but high-priority users cannot connect when user limits are reached
Solution Approach 1:
The patent segments the user population into different priority classes (high-priority and low-priority users). By segmenting users rather than treating them uniformly, the system can guarantee connection capacity for high-priority users while allowing the access point to serve maximum concurrent low-priority users when high-priority users are not actively connected.
Solution Approach 2:
The system dynamically changes the effective user limit parameter for different priority groups. High-priority users are granted guaranteed access regardless of the overall user limit, while low-priority users are subject to the access point's maximum concurrent user capacity. This parameter differentiation resolves the contradiction between connection guarantee and maximum capacity utilization.
3Reliability
If network resources are allocated to accommodate all users, then overall network access is improved, but high-priority users still experience poor connectivity due to bandwidth contention
Solution Approach 1:
The patent implements automated priority-based resource allocation that operates without manual intervention. The system automatically identifies high-priority users, classifies them into priority groups, and allocates bandwidth accordingly. This self-service mechanism ensures high-priority user connectivity while maintaining ease of operation, as the configuration once established automatically manages resource distribution without requiring continuous manual adjustment.
Data Source
AI summary
The present disclosure discloses a method and network device for dynamically prioritizing user connections on network. The disclosed system identifies a priority class associated with a client device prior to an initial connection from the client device to a network, and reserves access to a network resource for the client device based on the priority class prior to the initial connection. Specifically, the system evaluates a total capacity of the network resource and an anticipated usage of the network resource by the client device associated with the priority level. Then, the system will reject requests for accessing the network resource received from other client devices prior to the client device associated with the priority level accesses the network resource.
