Dynamic Bandwidth Allocation in Multilayer Network Tunnels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multilayer computer networks, existing technologies face challenges in dynamically managing bandwidth across different network layers, leading to inefficiencies in providing on-demand services as they lack the ability to monitor and allocate additional bandwidth effectively within existing communication tunnels.
Innovation Solution
A stateful Path Computation Element (PCE) is employed to monitor bandwidth usage and determine when additional bandwidth is required, allowing for the establishment of new communication tunnels or expansion of existing ones across multiple network layers using protocols like MPLS and GMPLS, ensuring that bandwidth demands are met without exceeding available resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If bandwidth is allocated statically in existing communication tunnels, then network infrastructure simplicity is maintained, but bandwidth availability and adaptability to changing demands deteriorate
Solution Approach 1:
The patent implements dynamic bandwidth allocation by enabling communication tunnels to adjust their bandwidth capacity in real-time based on monitored usage patterns and available network resources. The system transitions from static to dynamic bandwidth management, allowing tunnels to expand or contract their bandwidth allocation according to actual demand while maintaining network infrastructure simplicity through automated control mechanisms.
2Quantity of substance
If additional bandwidth is established through new communication tunnels, then bandwidth requirements are met, but network resource consumption and infrastructure complexity increase
Solution Approach 1:
The patent merges bandwidth resources across multiple existing communication tunnels by enabling dynamic bandwidth allocation and sharing mechanisms. Instead of establishing entirely new tunnels to meet bandwidth demands, the system consolidates and reallocates available bandwidth from existing tunnels, thereby meeting capacity requirements while minimizing the creation of additional network infrastructure and reducing overall resource consumption.
Solution Approach 2:
The patent makes existing communication tunnel infrastructure multi-functional by enabling them to dynamically serve different bandwidth capacities and traffic patterns. The same physical tunnel infrastructure can adapt to provide varying levels of bandwidth service to different applications and time periods, maximizing the utility of existing network resources rather than requiring dedicated infrastructure for each bandwidth requirement.
3Reliability
If bandwidth is monitored and dynamically allocated, then service quality and customer satisfaction improve, but processing overhead and system complexity increase
Solution Approach 1:
The patent implements self-service bandwidth management where the network system automatically monitors its own bandwidth usage, detects when additional capacity is needed, and establishes new communication tunnels or reallocates existing bandwidth without external intervention. This automated self-monitoring and self-adjustment mechanism maintains high service quality through continuous optimization while minimizing the processing overhead that would result from manual bandwidth management.

AI summary
Bandwidth usage for an existing communication tunnel between a first device and second device is monitored. A determination is made that additional bandwidth is required for communication between the first network device and the second network device. A determination is made that for the addition of the additional bandwidth would exceed available bandwidth for the existing tunnel. Additional bandwidth is established between the first network device and the second network device.
