Bandwidth Modulator Packet Suppression for Network Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bandwidth modulators in network technologies struggle to efficiently manage network congestion, leading to poor user experiences when networks become excessively congested.
Innovation Solution
A packet processing device and method that utilize a bandwidth modulator to perform suppression processes on packet flows with lower priority protocols when the device is in a congested state, while also allowing for dynamic adjustment of bandwidth through suppression and release processes.

Engineering Contradiction Analysis
1Productivity
If bandwidth modulators are used to manage network congestion, then network bandwidth control is improved, but user experience deteriorates when networks become excessively congested
Solution Approach 1:
The patent applies different suppression strategies to different packet flows based on their source ports and protocols. Low-priority packets from specific ingress ports are suppressed at ingress, while packets from other ports are suppressed at egress, creating localized quality adjustments rather than uniform bandwidth control that degrades overall user experience
Solution Approach 2:
The network traffic is segmented into different priority levels and handled differently. The system divides packet flows into high-priority and low-priority categories, applying selective suppression to low-priority flows while preserving high-priority traffic, thus maintaining user experience for critical applications even during congestion
2Productivity
If suppression processes are applied to low-priority packet flows, then bandwidth efficiency is improved, but network complexity increases
Solution Approach 1:
The system performs preliminary classification of packet flows by protocol type and ingress port before congestion occurs. By pre-identifying low-priority flows and setting up suppression rules in advance, the device avoids complex real-time decision-making during congestion, reducing operational complexity while maintaining bandwidth efficiency
Solution Approach 2:
The bandwidth modulator acts as an intermediary component that sits between ingress/egress ports and the core switching fabric. It handles the complex suppression logic in a dedicated module, isolating the complexity from the main packet forwarding path and simplifying the overall device architecture

AI summary
A first packet flow and a second packet flow support a first protocol, a third packet flow and a fourth packet flow support a second protocol, and a priority of the first protocol is lower than a priority of the second protocol. The first packet flow and the third packet flow are transmitted from a first ingress port to a first egress port. The second packet flow and the fourth packet flow are transmitted from a second ingress port to a second egress port. When the packet processing device is in a congested state, a bandwidth modulator performs a first suppression process on the first packet flow at the first ingress port, and the bandwidth modulator performs a second suppression process on the second packet flow at the second egress port or on the third packet flow at the first ingress port.
