Solution Overview
Problem
As Ethernet networks increasingly carry diverse traffic, including voice, data, and multimedia, the growing number of portable devices raises concerns about battery life due to increased power consumption during communication, necessitating energy-efficient networking solutions.
Innovation Solution
A method and system for end-to-end management of energy-efficient networking protocols, where messages with distinct markings and fields defined by IEEE 802.1Qat are used to configure energy-efficient parameters along network paths, enabling or disabling energy-saving techniques like Low Power Idle and sub-rating, based on application requirements and quality of service, using protocols like SNMP and LLDP.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If energy-efficient networking protocols are implemented to reduce power consumption, then battery life is extended, but network performance and quality of service may be compromised
Solution Approach 1:
The patent implements dynamic adjustment of energy-efficient parameters along network paths based on real-time traffic conditions, application requirements, and quality of service demands. The system can enable or disable energy-saving techniques like Low Power Idle and sub-rating at different locations and times, allowing the network to adapt between power saving mode and performance-critical mode as needed
Solution Approach 2:
The patent applies different energy-efficient parameters to different segments of the network path based on local conditions. Each network node can be configured with specific EEN parameters tailored to its location, traffic characteristics, and quality of service requirements, rather than applying a uniform energy-saving approach across the entire network
2Use of energy by moving object
If energy-efficient parameters are configured along network paths, then power consumption is reduced, but network complexity increases due to additional message types and configuration protocols
Solution Approach 1:
The patent leverages existing network management protocols like SNMP and LLDP to carry energy-efficient parameter configurations, making these protocols multi-functional. By reusing established infrastructure and message formats, the system avoids creating entirely new management mechanisms, thereby limiting the increase in network complexity while still enabling sophisticated energy control
3Duration of action of moving object
If energy-saving techniques are enabled along network paths, then battery life is extended for portable devices, but data transmission quality may be affected
Solution Approach 1:
The patent implements feedback mechanisms that monitor traffic conditions, packet loss, and quality of service metrics along network paths. Based on this feedback, the system dynamically adjusts energy-efficient parameter settings to maintain acceptable data transmission quality while maximizing power savings. When quality degradation is detected, the system can raise or lower energy-saving aggressiveness accordingly

AI summary
Aspects of a method and system for end-to-end management of energy efficient networking protocols are provided. In this regard, a path between two network nodes may be determined and one or more messages may be generated. The one or more messages may be communicated to one or more network nodes along the determined path and may configure an EEN control policy and/or one or more (EEN) parameters in those network nodes. The one or more generated messages may comprise a distinct marking that may, upon detection by the network nodes along the determined path, trigger configuration of the EEN control policy and/or EEN parameters within the one or more network nodes. The one or more messages may be may be utilized to enable and disable EEN in one or more network nodes along the path.
