Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portal devices require host processor involvement for bridging and routing, leading to buffering requirements and reduced data transfer rates due to the need for processing wireless network frames before transmission through wired networks.
Innovation Solution
Implementing a method and system where the wireless network interface subsystem performs bridging and routing offload by determining the appropriate network interface subsystem and transcoding frames independently, reducing the need for host processor intervention and buffering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the host processor performs bridging and routing functions, then the system can execute routing protocols and determine network interface subsystems, but the wireless network interface subsystem must buffer frames and data transfer rates are reduced
Solution Approach 1:
The patent extracts the bridging and routing functions from the host processor and relocates them to the wireless network interface subsystem. This is achieved by implementing a network interface subsystem that includes a processor capable of executing routing protocols and performing bridging operations independently, thereby eliminating the buffering requirement and associated data transfer rate limitations imposed by host processor involvement.
2Adaptability or versatility
If the host processor performs bridging and routing determinations, then routing protocols can be executed, but buffering requirements increase
Solution Approach 1:
The patent extracts the routing determination functionality from the host processor and embeds it within the network interface subsystem. The subsystem includes a processor that can independently execute routing protocols such as OSPF and perform spanning tree algorithm calculations, eliminating the need to buffer frames while the host processor makes routing determinations.
Solution Approach 2:
The network interface subsystem becomes self-sufficient by incorporating the capability to execute routing protocols and make routing decisions independently. This self-service approach allows the subsystem to process and forward frames without requiring host processor intervention, thereby eliminating buffering requirements.
3Adaptability or versatility
If the host processor transcodes wireless network headers, then frame conversion between networks can be performed, but processing time increases
Solution Approach 1:
The patent extracts the header transcoding function from the host processor and integrates it into the network interface subsystem. The subsystem includes hardware or software components capable of converting wireless network headers (e.g., IEEE 802.11) to wired network headers (e.g., IEEE 802.3) independently, eliminating the time delay associated with host processor-based transcoding operations.

AI summary
Aspects of a method and system for bridging and routing offload in a multiport wireless system are presented. Various aspects of the system may include a wireless network interface subsystem that enables transcoding of at least a portion of a data packet received by the wireless network interface subsystem. The wireless network interface subsystem may enable transfer of the transcoded portion of the data packet from the wireless network interface subsystem to a wired network interface subsystem that is communicatively coupled thereto. The transcoded portion of the data packet may be compliant with a format utilized by the wired network interface subsystem.
