# MUXER--A New Equipment for Energy Saving in Ethernet
## 6 Conclusions  
An important challenge for modern and powerful network equipment is to reduce energy consumption. The Energy Efficient Ethernet (EEE) standard, approved by IEEE in 2010, implements low-level mechanisms to improve Ethernet energy efficiency. Such standards, however, will not adopt in practice until their effects on workload performance are well understood. Energy consumption by network equipment and network infrastructure has a vast negative impact on sustainability of energy resources, which should be controlled by improving their power management efficiency. Currently, different manufacturer has their own equipment for controlling energy uses, but they have many limitations. Still, the fact that they are not yet ready for extensive deployment are discussed in all these articles [44; 45; 46; 47]. Therefore, MUXER has good future prospects. We will make our device more robust and efficient by considering heterogeneous property of network with its damage and replace issues in future. We must consider response time or latency of MUXER in our future work for different behavior of network and bandwidth.  
In this paper, a new network equipment named MUXER for reducing power consumption of the network is proposed. MUXER is a simple device which is put before the switches in the network that can receive the traffic from end-terminal or other devices and forward them to correspondence switches. This proposed device can control one or more switches in the same level of network to perform the turn-on or turn-off power function of switches when network traffic is in high-load or low-load conditions. The effectiveness of our proposed device has been proved in the analysis and experiment results. When network administrator can measure and put the compatible amount of MUXERs in network, they can be a power efficient solution for network. Otherwise, they increase the total power consumption of network many times. In this paper, our proposed approach has just included some prototype components and some prototype functions. Future work focuses on how to define some real thresholds which are installed in MUXER, how to build some prototypes of MUXER, and to apply them to a real LAN network to have some improvements that can be made finished products. In the future, this approach can be applied to the bigger network architecture and big enterprise which has the potential to save a large amount of energy usage.
