Asymmetrical Dynamic Routing for Network Bandwidth Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication networks face challenges in dynamically adjusting bandwidth capacity to meet changing traffic demands, leading to underutilization of resources and latency issues due to fixed channel plans and bandwidth mismatches between requests and responses.
Innovation Solution
A network device with active and idle optical data ports, connected by light re-directing devices, dynamically adjusts bandwidth capacity by enabling idle ports and redirecting data signals when bandwidth thresholds are exceeded, using a communication protocol to manage wavelength allocation and redirect data flows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network devices are engineered for worst-case traffic volumes, then service commitments are met, but network resources are under-utilized
Solution Approach 1:
The patent implements dynamic bandwidth adjustment by enabling network devices to flexibly allocate bandwidth capacity based on real-time traffic conditions. The system transitions from static worst-case engineering to dynamic resource allocation, allowing bandwidth to be adjusted upward when needed and relaxed when traffic demand is lower, thereby maintaining service commitments while improving resource utilization.
2Productivity
If manual reconfiguration is performed when traffic patterns change, then network capacity is optimized, but reconfiguration time and cost increase
Solution Approach 1:
The patent enables network devices to automatically detect traffic pattern changes and self-reconfigure their bandwidth allocation without manual intervention. The system monitors traffic conditions and dynamically adjusts bandwidth capacity, eliminating the need for time-consuming manual reconfiguration while maintaining optimized network capacity.
3Loss of time
If bandwidth capacity is increased to handle response traffic, then latency is reduced, but bandwidth is wasted during request transmission
Solution Approach 1:
The patent implements asymmetrical bandwidth allocation that recognizes the different bandwidth requirements for requests versus responses. The system allocates higher bandwidth capacity specifically for response transmission (when content is sent back to clients) while using lower bandwidth for request transmission (when small requests are sent to servers), thereby reducing latency for content delivery while avoiding bandwidth waste during request phases.

AI summary
An asymmetrical and dynamic routing system (ADRS) is provided to enable the dynamic adjustment of the bandwidth capacity of two or more network devices exchanging data. The two or more network devices monitor their current bandwidth demand between themselves and others in a network and a first network device can transmit bandwidth request to a second network device when the first network device reaches transmission bandwidth capacity. Each network device is further configured with additional transmit and receive ports and can be selectively enabled in response to a bandwidth request from other network devices. Each network device is further configured to generate control signals that are sent to optical mirrors to re-direct data signals to or from the one or more enabled additional transmit and receive ports.
