Energy consumption relative to network products, users are more concerned about equipment performance, price and ability to support future business. After all devices can play a good role, is the buyer's mind. But also resulted in a large environment, energy efficiency, network equipment be easily overlooked aspect of leakage. In the energy-saving servers, power, air conditioning and other equipment have been popular round today, people focus fell on the network device.
Energy-hungry
Statistics show that a core layer routing switch about the actual power between 800W ~ 1500 W, in accordance with the all-weather 365 × 24-hour operation basis, its annual electricity consumption of about 7,000 ~ 13,000 kwh. The current standard by Beijing, 1 yuan per kWh of industrial power calculation, a core router of electricity per year in 10,000 to 2 million a year. This is ruled out convergence layer and access layer, ranging from the number of switches, edge devices, as well as to control the indoor temperature by the addition of the results of air-conditioning facilities. According to the survey, a Shanghai operators monthly electricity bills as high as 100,000 yuan is huge. Large power network equipment, impact on operating costs high, is astounding.
Faced with such high power costs, operators buy network equipment in the total cost of ownership for the network increasing degree of attention, especially in the current energy crisis, saving the situation of the wind become the United States and Germany, will feature similar performance Product comparison, energy saving, low-power network devices into a user's choice.
Currently, many network equipment vendors will be saving and environmental protection as an important part of the implant design of its products. Such as IBM's "Project Big Green" program, D - Lin k introduced green switch products, J unip er release to low energy consumption as a selling point of the core router T1600.
J unip er which has just launched the "Big Mac" router T1600 is the industry's first to focus on energy efficiency as a core device. It is reported that, compared to similar competitive platform, the router can save 30% electricity and 30% cooling capacity. At the same time can be as much as possible re-use of hardware and line cards, reduce waste, protect the environment and cost savings. T1600 also herald the introduction of the core level as a big power, high-capacity router is also becoming the main energy.
Ethernet victory
Experts pointed out that: At present, old and new communication network equipment in the staggered, from the consumption of view is also uneven, through the replacement of inefficient equipment in the network, rationally adjust electricity load can effectively meet the energy saving effect. But unless the use of investment in equipment renovation methods, new equipment with energy efficient replacement of old equipment consumes large, otherwise this part of the electricity must be guaranteed and can not be saved.
Therefore, the search for more energy-efficient equipment and network technology is imperative. Power over Ethernet (P o E) with its low-cost, more secure, energy-efficient features to win more and more attention. Currently, more and more network equipment providers already provide support for Power over Ethernet products. IE EE 802.3 af standard PoE network has two basic components: provision of power supply equipment, power equipment, known as the (P SE); receive and use the power of the device, known as the power supply device was (PD). In to any network device when connected to the PSE, PSE must first determine or "discover" devices are not PD. This ensures that the standard may not meet the existing PoE Ethernet devices will not be mistakes made power, or may be damaged. The discovery process as an extension option, PD can also provide much power required to classify PSE. This feature can provide effective support for the PSE will help its power in an efficient manner.
With IE EE 802.3 af standard is established, a large number of applications are rolling in, such as Bluetooth access points, network printers, IP phones, network cameras, security systems, PoE controller market is expected to grow from 3,600 in 2006 million port expansion to 110 million in 2008 port.
Endless energy
Dedicated Ethernet energy efficiency standards development work EEE (Energy Ethernet) research team has recently achieved a new milestone. IEEE Executive Committee has adopted in mid-July EEE Study Group to develop standards for energy conservation projects authorized by the Ethernet application, which means the team can save energy and efficient Ethernet as a mandate to work more seriously. Resources for the Ethernet link is idle for most of the situation, the team sought to redefine the Ethernet auto-negotiation via technology, as soon as possible to achieve in milliseconds seamless speed physical layer Ethernet switch stage to reduce the flow of data in the low speed of the network, saving the overall Ethernet switching device power consumption. The team estimated that if they worked out in the future, the standard can be implemented, the only year in the United States could save 450 million U.S. dollars of energy costs.
The present case, PoE market is mainly dominated by three major applications, namely the wireless access point (W AP), VoIP phones and security systems including network cameras. As to the metro Ethernet technology and telecom business development, energy conservation became broader.
