Network Path Placement Using Power Usage Ratings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for modeling power usage of network devices are computationally intensive and infeasible due to non-linear power consumption patterns, making precise modeling difficult and resource-intensive, and frequent communications are needed for accurate power measurements which are beyond the control of routing protocols.
Innovation Solution
Categorizing network devices into power usage ratings based on power bands defined by a network-wide policy, using extended administrative groups (EAGs) to exchange power usage ratings, and performing path placement based on these ratings to optimize power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If frequent communications are used for accurate power measurements, then measurement precision is improved, but use of energy and device complexity increase
Solution Approach 1:
The patent uses power usage ratings (PURs) as simplified copies or representations of actual power consumption. Instead of continuously measuring actual power usage, the system exchanges and processes these rated values through routing protocols, achieving path placement decisions without the energy-intensive continuous measurement process.
Solution Approach 2:
The patent employs simplified power usage ratings that can be quickly exchanged and updated, replacing the need for expensive and time-consuming actual power measurements. These ratings are sufficient for routing decisions and can be updated infrequently, reducing communication overhead and energy consumption.
2Measurement precision
If frequent communications are used for accurate power measurements, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent uses power usage ratings (PURs) as simplified copies or representations of actual power consumption. Instead of continuously measuring actual power usage, the system exchanges and processes these rated values through routing protocols, achieving path placement decisions without the energy-intensive continuous measurement process.
Solution Approach 2:
The patent segments the power management function from the routing function. Power usage ratings are collected and processed separately, then used as input for routing decisions. This segmentation allows routing protocols to operate independently from complex power measurement systems, reducing overall system complexity.
3Measurement precision
If non-linear power consumption patterns are modeled precisely, then measurement precision is improved, but computational resources required increase
Solution Approach 1:
The patent uses power usage ratings (PURs) as simplified copies or representations of actual power consumption. Instead of continuously measuring actual power usage, the system exchanges and processes these rated values through routing protocols, achieving path placement decisions without the energy-intensive continuous measurement process.
Solution Approach 2:
The patent changes the parameter representation from actual non-linear power consumption values to standardized power usage ratings. This parameter transformation simplifies the data structure and enables linear processing in routing protocols, reducing computational complexity while maintaining sufficient accuracy for path placement decisions.
