Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless local area networks (WLANs) face challenges in processing complexity and bandwidth constraints due to the integration of advanced services like e-mail and video broadcasts, necessitating a reduction in processing complexity and overhead information transmission.
Innovation Solution
A node configured to operate in a cluster uses an identifier assigned to an access terminal to route data through the network, allowing for efficient data routing and minimizing the need for unique link layer addresses, thereby reducing processing complexity and conserving bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional routing methods using unique link layer addresses are used, then data routing can be achieved, but processing complexity increases and bandwidth is consumed
Solution Approach 1:
The patent extracts the routing function from the link layer and moves it to the network layer. By using network layer addresses (IP addresses) instead of link layer addresses for routing decisions, the system reduces link layer processing complexity while maintaining reliable data routing. The frame buffer uses network layer information to make routing decisions, separating routing functionality from the link layer protocol.
Solution Approach 2:
The patent introduces a frame buffer as an intermediary structure that stores and processes data frames. The frame buffer uses network layer addresses to identify destinations and routes data through the cluster, acting as a mediator between the physical layer transmission and the network layer routing decisions, thereby reducing processing complexity at the link layer.
2Reliability
If unique link layer addresses are assigned to each access terminal, then data routing is enabled, but bandwidth is consumed for overhead information transmission
Solution Approach 1:
The patent extracts the addressing function from the link layer to the network layer. By using network layer addresses (which can be reused and are more efficiently managed) instead of assigning unique link layer addresses to each access terminal, the system reduces the amount of overhead information transmitted at the link layer, thereby conserving bandwidth while maintaining routing capability.
Solution Approach 2:
The patent makes network layer addresses universal by allowing them to be reused across different access terminals and clusters. This multi-functionality of network layer addresses eliminates the need for unique link layer addresses for each terminal, reducing overhead bandwidth consumption while maintaining the ability to route data to any access terminal.
3Adaptability or versatility
If more services are integrated into mobile handsets, then functionality increases, but processing complexity and bandwidth constraints are exacerbated
Solution Approach 1:
The patent segments the network into clusters with hierarchical routing. By organizing access points into clusters and using a two-level routing approach (within-cluster and between-cluster routing), the system reduces the processing burden on individual nodes while supporting multiple services. This segmentation allows complex services to be routed efficiently through the cluster without increasing overall system processing complexity.
Solution Approach 2:
The patent uses the frame buffer as an intermediary that handles data processing and routing decisions. The frame buffer consolidates processing tasks by using network layer information to make routing decisions, thereby reducing the processing complexity at individual access points while supporting service integration across the entire network.
Data Source
AI summary
Various techniques for routing data through a cluster are disclosed. The cluster includes a number of nodes that support communications by an access terminal. A node may be configured to use an identifier assigned to an access terminal to route data associated with the access terminal to another node in the cluster. The identifier is assigned by any node in the cluster.
