Service Flow Segregation for Home Network Traffic Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home network configurations lack the ability to differentiate and manage separate bandwidths and quality of service for residential and work-related traffic, leading to security concerns and performance issues when employees work from home, as all traffic is intertwined and competes for resources.
Innovation Solution
Implementing a system with separate downstream and upstream service flows, each with distinct quality of service and bandwidth, allowing for segregation of residential and work-related traffic through a cable modem with router functionality, enabling separate Wi-Fi SSIDs and service flow groups to prioritize and manage traffic types effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate service flows are implemented for residential and work-related traffic, then network security and performance are improved, but device complexity increases
Solution Approach 1:
The patent divides network traffic into separate service flows - a first service flow for residential traffic and a second service flow for work-related traffic. Each service flow has dedicated bandwidth and quality of service parameters, allowing independent management and prioritization of different traffic types through the cable modem and network node.
2Reliability
If separate service flows with different bandwidths are provided, then quality of service for work traffic is improved, but network resource allocation complexity increases
Solution Approach 1:
The patent applies different quality of service characteristics to different service flows. The second service flow for work-related traffic is configured with higher priority and guaranteed bandwidth, while the first service flow for residential traffic has standard service parameters. This allows localized optimization of network resources for specific traffic types.
3Device complexity
If all traffic is intertwined in a single service flow, then device complexity is reduced, but network performance and security deteriorate
Solution Approach 1:
The patent segments network traffic into distinct service flows to prevent resource contention between residential and work-related applications. By separating traffic at the service flow level rather than requiring separate physical connections, the system maintains manageable complexity while significantly improving network performance and security for remote work scenarios.

AI summary
A service provider server is provided for use with a network node, and a cable modem. The service provider server includes a memory and a processor configured to execute instructions stored on the memory to cause the service provider server to provide a first downstream service flow to the cable modem by way of the network node, the first downstream service flow having a first set of privileges, receive a first upstream service flow from the cable modem by way of the network node, provide a second downstream service flow to the cable modem by way of the network node, the second downstream service flow having a second set of privileges that are different from the first set of privileges, and receive a second upstream service flow from the cable modem by way of the network node.
