Multi-Source Inbound QoS for Receiver Oversubscription
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In computer networking, especially in site-to-site VPNs, receiver oversubscription occurs due to independent providers unaware of total unused receiver capacity, leading to adverse impacts on application performance.
Innovation Solution
Implementing a Multi-Source Inbound QoS process that calculates current usage rates of provider entities, classifies them by network traffic priority, and adjusts bandwidth through fair sharing policies and link sharing at the provider-entity level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple independent providers send traffic to a receiver without coordination, then each provider can independently utilize receiver capacity, but the sum of all receiver traffic exceeds the rated receiver capacity causing receiver oversubscription
Solution Approach 1:
The patent implements a feedback mechanism where the receiver monitors total incoming traffic from multiple providers and sends signaling information back to providers about available capacity. This feedback loop enables providers to adjust their traffic rates dynamically, ensuring the sum of traffic does not exceed receiver capacity while maintaining independent operation. The receiver calculates available capacity based on rated capacity and current utilization, then communicates this to providers for rate adjustment.
Solution Approach 2:
The system dynamically adjusts provider traffic rates based on real-time receiver capacity conditions. Rather than static allocation, the patent enables continuous adaptation where providers can increase or decrease their traffic rates in response to changing receiver availability. This dynamic approach allows the system to fully utilize receiver capacity when available while preventing oversubscription, thereby maintaining both independence and reliability.
2Productivity
If a receiver accepts traffic from multiple independent providers, then traffic diversity and utilization increase, but lack of awareness of total unused capacity leads to receiver oversubscription
Solution Approach 1:
The patent introduces the receiver as an intermediary that mediates between multiple independent providers and the network. The receiver actively monitors total traffic levels, calculates available capacity, and communicates this information to providers. This intermediary role simplifies bandwidth management by centralizing capacity awareness at the receiver, eliminating the need for complex coordination mechanisms among providers while preventing oversubscription.
Solution Approach 2:
The system enables providers to self-adjust their traffic rates based on signaling information received from the receiver. Rather than requiring complex external management or coordination between providers, each provider independently monitors receiver signals and autonomously adjusts its traffic rate accordingly. This self-service approach increases productivity while avoiding the complexity of centralized control or inter-provider communication protocols.
3Reliability
If site-to-site VPNs are established one at a time with dedicated equipment, then secure connections are maintained, but resource intensity and setup complexity increase
Solution Approach 1:
The patent merges multiple individual VPN connections into a single receiver entity that handles traffic from multiple providers simultaneously. Instead of requiring separate dedicated equipment and configurations for each VPN, the system consolidates these functions at the receiver, which monitors and manages aggregate traffic from all providers. This merging maintains security through centralized control while dramatically reducing setup and maintenance complexity.
Solution Approach 2:
The receiver is designed as a universal entity that can simultaneously handle traffic from multiple different providers through a single interface and configuration. Rather than requiring provider-specific VPN setups, the receiver provides multi-functional capability to manage diverse traffic sources, maintaining secure connections through unified policies while eliminating the need for multiple dedicated equipment instances.
