Introduction

 2% of energy consumed in the world by computers.

 Performance penalties are very severe

 Poor resource allocation–

non-uniform Traffic

 IXP2400 NP consumes – 9-12W (400MHz)

- 13-16W (600MHz)

 Our proposed method - saved 25-28% of power

consumption.

Problem and Solution

Problem:Network Processor (NP) Consumes more power.

Solution:

Microengines(ME) are consumed more than 80%

of Power

MEs are Switched off/on based upon traffic
