Traffic Control Element Buffering for Serial Stream Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication network systems require large routers with significant processing capability to convert discrete traffic packets into serial streams, leading to space occupancy issues and increased computational load due to error correction and encryption, which can cause traffic congestion.
Innovation Solution
A communication network traffic control element with a processor and buffer that receives discrete traffic packets, converts them into a serial stream, and controls the traffic flow rate independently, using a field programmable gate array (FPGA) and temporary memory store to manage traffic flow and apply selective processing schemes, preventing overload and optimizing transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a large router with significant processing capability is used to convert discrete traffic packets into serial streams, then the traffic conversion function is improved, but the space occupancy and device complexity increase
Solution Approach 1:
The patent divides the traffic control function into separate components: a receiver for accepting packets, a processor for conversion, and a buffer for flow control. This segmentation allows each component to be optimized independently, reducing overall system complexity while maintaining conversion capability
Solution Approach 2:
The buffer acts as an intermediary between the receiver and processor, decoupling their operations. This allows the processor to work at its own pace while the receiver accepts packets continuously, eliminating the need for a large router with significant processing capability
2Reliability
If error correction and encryption processing is applied to traffic, then communication reliability is improved, but the computational load and processing time increase
Solution Approach 1:
The buffer temporarily stores traffic packets before they are processed by the processor. This preliminary storage allows error correction and encryption to be applied in a controlled manner without causing congestion or increasing processing time, as packets are ready for immediate processing when the processor is available
3Reliability
If the flow of traffic is limited to a router to avoid congestion, then traffic delivery reliability is improved, but the processing bottleneck increases
Solution Approach 1:
The buffer serves as an intermediary that absorbs traffic flow variations. It receives packets from the receiver at variable rates and supplies them to the processor at a steady rate, preventing congestion upstream while maintaining high processing throughput without creating a bottleneck

AI summary
A communication network traffic control element is disclosed which is arranged to receive traffic, such as voice and data, as a plurality of discrete traffic packets at an input and communicate the traffic as a serial traffic stream to an output. The traffic control element can include a receiver which is arranged to receive the traffic packets, and a processor which is arranged to communicate the serial traffic stream to the output. The processor can include a buffer to vary a traffic output rate from the processor independently of an input rate of traffic flow to the receiver.
