EMAN
− Energy-Management Activity
GROUP 5 & 6
Speakers: Tianyu Shi, Jing Yang, Sebastian Marin
Supporters: Krago, Steve Sam, Xi Yang
SUMMARY
The EMAN working group provides a forum for energy management.
By creating information models that describe devices and their use with respect to power
and energy, network administrators can achieve energy management with a sophistication
on par with other network management areas. We propose that by introducing context,
power/energy descriptions, monitoring, and state control, administrators can create
sophisticated energy management and analytic management systems.

Energy Management Introduction & Requirement by Tianyu Shi & Krago
INTRODUCTION
• The requirement of reducing the energy cost and achieving the energy
sustainability.
• At the ietf meeting in 2009, the first time energy - management (eman) was
discussed.
• In august 2010, eman working group was established.

MODELLING RELATIONSHIPS BETWEEN DEVICES
In order to improve the energy consumption efficiency, the first step should enable
the network equipment can report their energy consumption by themselves.
EMAN defines the reference models of energy consumption monitoring to
standardize energy management method.
The most basic way of energy consumption management is making equipment can
report themselves En consumption situation through the network protocol.

CONCLUSION
• This Presentation：
1. Analyzed The Requirement Of EMAN
2. Summarized The Framework
3. Gave Definitions Of Related MIB
• Recommendation:
•
•
•
•
21
EMAN can be achieved on par with other management areas.
Can contribute to optimization of energy use worldwide.
Security should be considered
Readable objects in mib modules may be considered sensitive or vulnerable in some network
environments.
