Communication Pipe Allocation for QoS in Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The rapid increase in communication network traffic poses challenges in optimally routing traffic to ensure Quality of Service (QoS) as network hardware improvements lag behind traffic growth, necessitating efficient allocation of communication pipes and links to maintain network stability and quality.
Innovation Solution
A method for allocating communication pipes in a network that determines required capacity based on traffic volume and QoS requirements, using a combined pipe-dimensioning approach with reciprocal link allocation to prioritize traffic flow through high-capacity links and manage bandwidth effectively, ensuring improved load balancing and network stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional routing methods are used, then network traffic can be transmitted, but Quality of Service cannot be guaranteed due to traffic augmentation outpacing hardware improvements
Solution Approach 1:
The patent implements dynamic pipe capacity allocation that adapts to changing traffic conditions. The system continuously monitors network state and adjusts pipe dimensions and link allocations in real-time, allowing the network to dynamically respond to traffic augmentation while maintaining QoS guarantees. This dynamic adjustment enables the network to handle increasing traffic volumes without sacrificing service quality.
Solution Approach 2:
The invention changes key network parameters including pipe capacity, link allocations, and routing decisions based on current network state and QoS requirements. By adjusting these parameters dynamically rather than using fixed configurations, the system can accommodate growing traffic demands while maintaining guaranteed service levels for different network flows.
2Productivity
If more network hardware is deployed to handle increased traffic, then traffic capacity increases, but network complexity and costs increase
Solution Approach 1:
The patent creates a universal allocation framework that can handle multiple types of network flows with different QoS requirements using the same infrastructure. The pipe dimensioning and link allocation mechanisms provide multi-functional capabilities, allowing a single network configuration to serve diverse traffic patterns without requiring separate dedicated hardware for each flow type.
Solution Approach 2:
Instead of adding hardware, the system achieves increased traffic capacity by optimizing existing resource parameters. The allocation unit adjusts pipe capacities and link assignments to maximize utilization of current infrastructure, thereby increasing effective capacity without proportional increases in hardware complexity.
3Stability of the object's composition
If traffic is routed through existing network paths, then network stability is maintained, but load balancing deteriorates as traffic augments
Solution Approach 1:
The system implements dynamic routing that continuously adapts path selections based on current network conditions and traffic patterns. As traffic augments, the allocation unit dynamically recalculates optimal paths and redistributes flows across available links, maintaining both network stability and effective load balancing through real-time adjustments rather than static routing tables.
Solution Approach 2:
The patent incorporates feedback mechanisms where the allocation unit monitors network state, pipe utilization, and link conditions, then uses this information to adjust routing decisions and pipe allocations. This closed-loop control ensures that load balancing remains effective even as traffic volumes increase, while network stability is maintained through controlled, feedback-driven adjustments.

AI summary
The communication network includes a plurality of nodes interconnected by a plurality of links. The allocation unit assigns one or more network flows to the communication pipe. The one or more network flows have the same source node and the same destination node. The allocation unit determines a required capacity of the communication pipe based on the amount of network traffic associated to the one or more network flows and based on one or more minimal quality of service requirements associated with the one or more network flows. The allocation unit allocates one or more links of the plurality of links to the communication pipe for routing the one or more network flows from the source node to the destination node.
