1、 AMERICAN NATIONAL STANDARD FOR TELECOMMUNICATIONS ATIS-0600015.08.2014 Energy Efficiency for Telecommunication Equipment Methodology for Measurement and Reporting for Small Network Equipment As a leading technology and solutions development organization, ATIS brings together the top global ICT comp

2、anies to advance the industrys most-pressing business priorities. Through ATIS committees and forums, nearly 200 companies address cloud services, device solutions, emergency services, M2M communications, cyber security, ehealth, network evolution, quality of service, billing support, operations, an

3、d more. These priorities follow a fast-track development lifecycle from design and innovation through solutions that include standards, specifications, requirements, business use cases, software toolkits, and interoperability testing. ATIS is accredited by the American National Standards Institute (

4、ANSI). ATIS is the North American Organizational Partner for the 3rd Generation Partnership Project (3GPP), a founding Partner of oneM2M, a member and major U.S. contributor to the International Telecommunication Union (ITU) Radio and Telecommunications sectors, and a member of the Inter-American Te

5、lecommunication Commission (CITEL). For more information, visit . AMERICAN NATIONAL STANDARD Approval of an American National Standard requires review by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is esta

6、blished when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be

7、considered, and that a concerted effort be made towards their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or using product

8、s, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of

9、 an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard. CAUTION NOTICE: This American National Standard may be revised or withdrawn a

10、t any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers of American National Standards may receive current information on all standards by calling or writing the American National Sta

Notice of Disclaimer Wi-Fi active with no connections and LAN ports not connected. 3.1.6 IMIX traffic: A stateless traffic profile that contains a mixture of frame sizes similar to a composition observed in the Internet (Internet traffic mix). 3.1.7 Maximum Demonstrated Throughput:

12、 The maximum non-drop data rate between WAN and LAN port in ingress direction (bps). 3.1.8 Port Utilization: Port throughput expressed as percentage of theoretical maximum throughput. 3.1.9 System Utilization: System throughput expressed as percentage of Maximum Demonstrated Throughput. 3.1.10 Teste

Example: Line rate for 1 Gb Ethernet is 1Gbps. 3.2 Acronyms DOCSIS; optical line termination; cellular data modems integrated into the main unit (excluding USB or similar dongles) Access Points 802.11 xx Switches Up to 11 ports Routers/Integrated Access Devices

15、 Router in any combination any products above 5 Metric Definition 5.1 TEER Metric Definition TEER is defined as a ratio of weighted throughput (Tw) to weighted power (Pw, the energy consumption rate) at low, idle and max states: PwTwTEER Where: Tw = 0.5*Tlow+ 0.35*Tidle+0.15*Tmax Tlow,Tidle, Tmax ar

16、e throughputs at low, idle, and max throughput states Pw = 0.5*Plow+ 0.35*Pidle+0.15*Pmax Plow,Pidle, Pmax are powers at low, idle, and max throughput states Notes on throughput: Tlow and Tidle are zero by default For interfaces with throughput (Tx) sensitive to distance, this is defined as: Tx= 0.5

17、*(Tx20% of max distance + Tx80% of max distance) (7)o :NOTE: The vendor test report should provide both a relevant standard (IEEE, ITU-T, etc) for the interface as well as the maximum distance used in the calculation. For small network equipment, this is the maximum non-drop data rate between WAN an

18、d LAN ports in the ingress direction. ATIS-0600015.08.2014 4 If multiple LAN interfaces are available, all interfaces shall be connected and idle. Maximum traffic shall only be sent through one interface based on the priority below:. 1. Wi-Fi 2. Ethernet 3. Others If multiple WAN interfaces are avai

19、lable, priority in testing shall be assigned to the higher speed interfaces. If possible, test multiple WAN ports simultaneously. 6 Test Procedure 6.1 General Measurement Condition The general requirements for measuring energy efficiency are defined in ATIS-0600015.2013. The following are the genera

20、l conditions for measurements within this standard: The equipment is to be powered and placed into the relevant operating mode. Allow the equipment to stabilize in this mode for 300 seconds. Measure the average power for a period of 15 minutes. 6.2 Equipment Configuration All testing shall be perfor

21、med on a fully configured EUT, as defined by the referenced application. For Idle, all ports shall be in an active state and ready to pass traffic. System software (SW) shall be properly configured prior to the test and all the necessary HW components installed. HW and SW shall be representative of

22、a production unit. There is no EUT configuration change allowed any time beyond preparation phase. This includes (but is not limited to) external configuration commands, scripts executing configuration commands on EUT during testing, etc. The EUT shall be placed in a shielded box/room for testing of

23、 Wi-Fi ports. RF signal strength shall be sufficient to connect with one client at maximum supported speed. 6.3 Traffic Generation/Operational Conditions 6.3.1 Traffic Topology Products with WAN and LAN ports shall be tested with traffic between the WAN and LAN ports to determine the NDR. Switches w

24、ith only LAN ports shall be tested with traffic between the uplink and downlink ports to determine NDR. If there is no dedicated uplink port, any two LAN ports may be used for the NDR test. USB, console ports and similar do not need to be connected during the testing. 6.3.2 Use of Traffic Generators

25、 Traffic generators are used to simulate traffic and collect the performance-related results according to the test conditions. Generators shall be configured for the correct traffic topology and profile. Simple IMIX packet length distribution patterns shall be used. Data inside the packets shall be random.
