Virtual Partition Scaling for Wireless Roaming Events
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless network architectures for large facilities face inefficiencies and scalability issues, leading to increased response times, network congestion, and potential crashes due to the inability to handle a growing number of wireless devices, particularly in environments where devices need to roam and communicate effectively across the facility.
Innovation Solution
Implementing a scalable wireless network architecture that utilizes virtualized layer 2 networks with a server computer to instantiate and manage virtual partitions associated with VLANs, allowing for horizontal scaling and efficient handling of increased traffic without increasing roam times or downtime, while containing malicious data and loops within specific VLANs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional wireless network architectures are used to handle increasing numbers of wireless devices, then network coverage is maintained, but network performance deteriorates due to congestion and increased response times
Solution Approach 1:
The network is segmented into multiple Virtual Local Area Networks (VLANs) that are dynamically created and managed. Each VLAN can be assigned to specific geographic zones or functional areas within the facility, allowing network traffic to be divided and managed in smaller, more efficient units. This segmentation prevents congestion by distributing traffic across multiple virtual networks rather than a single monolithic network.
Solution Approach 2:
The patent introduces a vertical dimension to network architecture by implementing hierarchical VLAN structures and multi-layer networking. Instead of simply adding more access points in the horizontal plane, the system creates multiple layers of network virtualization, allowing traffic to be routed through different virtual paths and layers, effectively adding dimensional complexity to manage device quantity.
2Quantity of substance
If more access points are added to handle increased device density, then network coverage is improved, but device complexity and cost increase
Solution Approach 1:
The network system is designed with universal, standardized components that can perform multiple functions. Access points and network infrastructure are configured to handle various device types and traffic patterns through a unified VLAN management system. This multi-functionality allows the same hardware infrastructure to scale efficiently without requiring specialized equipment for different scenarios.
Solution Approach 2:
The patent utilizes dynamic parameter changes in VLAN configurations, IP addressing schemes, and network routing tables to accommodate scaling needs. Rather than adding physical infrastructure, the system adjusts network parameters such as VLAN IDs, subnet masks, and routing protocols to efficiently manage increased device density, keeping hardware complexity low while maintaining network capability.
3Adaptability or versatility
If wireless devices roam across different VLANs, then network mobility is enabled, but re-authentication requirements increase response time
Solution Approach 1:
The system performs preliminary authentication and authorization actions before devices actually need to roam between VLANs. Network controllers pre-establish security contexts and routing permissions for devices that may need to access multiple VLANs, so when roaming occurs, the device can transition seamlessly without time-consuming re-authentication sequences.
Solution Approach 2:
The patent introduces network controllers and authentication proxies as intermediary components that manage VLAN transitions. These intermediaries handle the complex authentication and authorization processes between devices and multiple VLANs, shielding devices from the complexity of re-authentication and enabling fast, seamless roaming by managing credentials and permissions centrally.
4Ease of operation
If a single large VLAN is used to simplify network management, then ease of operation is improved, but reliability decreases due to broadcast storms and malicious data propagation
Solution Approach 1:
The network is segmented into multiple isolated VLANs that prevent broadcast storms and malicious data from propagating across the entire network. Each VLAN acts as a containment zone, and the patent implements inter-VLAN routing controls to manage communication between segments. This segmentation maintains reliability by limiting the scope of potential network failures while preserving management simplicity through centralized VLAN orchestration.
Solution Approach 2:
The patent converts the potential harm of network segmentation (which can complicate management) into a benefit by implementing automated VLAN management systems. The complexity of managing multiple VLANs is transformed into an advantage through automation, where software controllers automatically configure, monitor, and optimize VLAN structures, making the segmented architecture easier to manage than a single large VLAN while maintaining superior reliability.

AI summary
Techniques for a scalable wireless network feature for maintaining communications between wireless devices accessing a facility are described herein. A virtual partition for each wireless virtual local area network (VLAN) of a plurality of VLANs may be maintained. A virtual partition is configured to process mapping requests from one or more wireless devices of a particular VLAN of the VLANs. A threshold may be maintained that is associated with roaming per second events by the one or more wireless devices of the facility. A new virtual partition for a new VLAN may be instantiated based on information from the one or more wireless devices indicating that the roaming per second events exceed the threshold. One or more components of an intermediate distribution frame may be updated with mapping data to utilize with new wireless devices accessing the facility and for communicating with the new virtual partition for the new VLAN.
