window8之保持网络连接-Maintaining network connectivity

Maintaining network connectivity-保持网络连接原文地址：/en-US/library/windows/apps/hh761436目录Maintaining network connectivity-保持网络连接 (1)作用 (2)In this section (2)快速开始：管理连接状态的改变 (3)前提 (3)Summary (7)Related topics //相关文章 (7)作用Use the working.Connectivity namespace provided in the Windows Runtime to enable your app to monitor and maintain the integrity of a connected experience by registering for changes to network connection states or the data plan usage associated with a specific network connection.使用WinRT提供的working.Connectivity名字空间可以让你的应用程序通过注册网络连接的状态或者与一个特殊的网络连接关联的data的状态的监听器去监听和维护一段完整的连接。

（注：网络连接的状态通常是指网络的是否连接，连接速度，协议信息等等；与一个特殊的网络连接关联的data的状态：通过网络来对data作更新，我们不需要判断网络的状态，而只要判断data的状态就可以了，例如判断所需的data是否更新完毕。

）The topics in this section provide best practices and demonstrates how to register for these change notifications and respond to these events. For additional code examples, download the Network Information sample. For guidance specific to accessing the information for individual connections via connection profiles see, Accessing connection and data plan information.在这个章节中我们将提供最好的实例和演示如何为这些change通知注册监听器和对这些事件作出响应。

网件全网管路由交换机如何设置MLAG功能

网件全网管路由交换机如何设置MLAG功能网件是全球领先的企业网络解决方案，及数字家庭网络应用倡导者，那么你知道网件全网管路由交换机怎么设置MLAG功能吗?下面是店铺整理的一些关于网件全网管路由交换机如何设置MLAG功能的相关资料，供你参考。

网件全网管路由交换机设置MLAG功能的方法：在二层网络，可以通过生成树(STP)避免环路。

但STP会把部分端口阻塞，导致这一部分的链路的带宽造成浪费。

而且当某些链路中断而导致拓扑改变的时候可能导致网络振荡，这个中断的时间从几毫秒到十几秒不等。

使用MLAG技术可以使所有的链路都得以利用，而且在链路中断导致拓扑改变的时候不会导致网络的震荡。

MLAG可以是多台交换机上的端口组成一个LAG组，对端设备会认为自己的LAG组连接的对端是同一台设备，这样可以利用LAG的特性的有点做到上文说所的链路的充分利用和无间断转发。

MLAG又称为vPC。

目前Netgear的交换机当中，M6100和M7100可以支持MLAG。

本文档以两台M6100为例，说明如何配置MLAG，拓扑图如下：开启MLAG功能feature vpc配置LAG1作为peer-linkinterface lag 1no spanning-tree port modevpc peer-linkexitinterface 1/0/41udld enableaddport lag 1exitinterface 1/0/42udld enableaddport lag 1exit配置keepaliveinterface vlan 1ip address 192.168.1.1 255.255.255.0exitvpc domain 1peer-keepalive enablepeer-keepalive destination 192.168.1.2 source 192.168.1.1peer detection enableexit将LAG2和LAG3设置成MLAG链路interface lag 2vpc 1exitinterface lag 3vpc 2exit查看MLAG状态(M6100-3S) #show vpc briefVPC domain ID (1)VPC admin status...............................

电子信息专业英语(第二版)课件：Telecommunications

The golden age of automatic telephony occurred after World WarⅡwhen the entire long-distance network was automated. The invention of the transistor spurred the application of electronics to switching systems and led to the deployment of the first electronic switching in the late 1950s. Electronic switching made it possible to design and build switches with greater capacity.
Satellite communication was first proposed in 1945 by the British science fiction writer, Arthur C. Clarke. Satellite communications became a reality with the launching of the Russian satellite Sputnik (in 1957) and the American satellite Explorer (in 1958). The AT&T Telstar was the first experimental satellite capable of relaying television (TV) programs across the Atlantic Ocean. It was launched from Cape Canaveral(now Cape Kennedy)on July 1962. The first global civil communications satellite, INTELSAT Ⅰ(Early Bird), was launched in April 1965.

But it is not a path she’d originally planned to follow. After completing her psychology degree. White took a Master’s in neuro-science (神经科学), fully expecting an academic career. But after her interest was raised by the part of the course that involved coding (编码), she decided to take a Master’s course in computer science. She graduated with flying color.Now 27, White hasn’t looked back. She joined Oakbrook Finance in Nottingham as a software developer, and stayed for two years, rounding off her time there by winning Rising Star of the Year at the 2018 Women in IT awards. At Unidays, a business offering discounts to students, she works as a back end developer in the maintenance team, “working on the systems and making them better”. It’s a job she loves. “It’s a challenge every day and you never get bored. There is always something to learn.” she says.White believes that some graduates are put off technology careers because they don’t realize the range of jobs available, “A lot of people think tech is programing. But there’s also design product management—and everything in life is to do with tech these days. Whether it’s buying something with your cards or posting something on social media, you can’t really avoid it.”A common misunderstanding, she says, is that IT is all about maths. “I’m terrible at maths and it scared the living daylights out of me when I started this because I thought I wouldn’t be able to do it,”In practice, it hasn’t been a problem, and she has found that there are a lot of creative elements in programing. Her psychology background has proved to be a bonus, enabling her to bring a different perspective to her work, particularly when she has to cooperate with user experience designers.As for the future, White wants to learn as much as she can and become very strong in the area.7．How many subjects has White learned?A．Two.B．Three.C．Four.D．Five.8．What can we infer from Paragraph three?A．Nothing is impossible because of technology.B．More graduates are being attracted by technology.C．Technology contributes to the development of economy.D．We can’t live a life free from technology nowadaya.9．What does the underlined word “bonus” in the fourth paragraph mean?A．Extra benefit.B．Strong influence.C．Unexpected challenge.D．Satisfying income.10．Which of the following is the best title for this passage?A．Jess White, a Dependable and Helpful 1ady.B．Jess White, a Talented and Confident Programmer.C．Jess White, a Curious and Knowledgeable Learner,D．Jess White, a Hard-working and Proud Expert.When a chunk of ice fell from a collapsing glacier(冰川)on the Swiss Alps’ Mount Eiger in 2017, part of the long deep sound it produced was too low for human ears to detect. But these vibrations held a key to calculating the ice avalanche’s(崩塌)critical characteristics.Low-frequency sound waves called infrasound that travel great distances through the atmosphere are already used to monitor active volcanoes from afar. Now some researchers in this field have switched focus from fire to ice: dangerous blocks snapping off glaciers. Previous workhas analyzed infrasound from snow avalanches but never ice, says Boise State University geophysicist Jeffrey Johnson. “This was different,” Johnson says. “A signature of a new material has been detected with infrasound.”Usually glaciers move far too slowly to generate an infrasound signal, which researchers pick up using detectors that track slight changes in air pressure. But a collapse—a sudden, rapid breaking of ice from the glacier’s main body—is a prolific infrasound producer. Glacial collapses drive ice avalanches, which pose an increasing threat to people in mountainous regions as rising temperatures weaken large fields of ice. A glacier “can become detached from the ground due to melting, causing bigger break— offs,” says University of Florence geologist Emanuele Marchetti, lead author of the new study. As the threat grows, scientists seek new ways to monitor and detect such collapses.Researchers often use radar to track ice avalanches, which is precise but expensive and can monitor only one specific location and neighboring avalanche paths. Infrasound, Marchetti says, is cheaper and can detect break—off events around a much broader area as well as multiple avalanches across a mountain. It is challenging, however, to separate a signal into its components (such as traffic noises, individual avalanches and nearby earthquakes) without additional measurements, says ETH Zurich glaciologist Malgorzata Chmiel. “The model used by Marchetti is a first approximation for this,” she says. Isolating the relevant signal helps the researchers monitor an ice avalanche’s speed, path and volume from afar using infrasound.Marchetti and his colleagues are now working to improve their detectors to pick up more signals across at-risk regions in Europe, and they have set up collaborations around the continent to better understand signals that collapsing glaciers produce. They are also refining their mathematical analysis to figure out each ice cascade’s physical details.11．What can we learn from Paragraph 2 and Paragraph 3?A．Infrasound has a major role to play in discovering new materials.B．Ice avalanches are a bigger threat to people than volcanic eruptions.C．Researchers are trying to use infrasound in detecting ice avalanches.D．Scientists employ infrasound more in mountain areas than in other places.12．Which is an advantage of infrasound over radar?A．The combination with other relevant signals.B．The accuracy in locating a certain avalanche.C．The ability in picking up signals in wider areas.D．The sensitivity in tracking air pressure changes.13．The underlined word “this” in Paragraph 4 refers to________.A．distinguishing different components of a signalB．detecting multiple avalanches at the same timeC．calculating the speed and path of ice avalanchesD．monitoring the specific location of ice break—offs14．Which of the following would be the best title for the passage?A．From Fire to Ice B．Glacier WhispersC．Nature is Warning D．Secret of Ice AvalanchesWhen you think of how much you do with your hands all day, from making yourself fried eggs in the morning to folding laundry in the evening, it becomes clear how vital skillfulness is to daily life. 15 You need it to play sports, for example, or use a remote or a video game controller.For some specific tips on improving skillfulness, we turned to a personal trainer Abdias Rojas. He said, “there are so many movements you can do to actually improve not just the strength of your hands but also flexibility in your hands.” 16Put rubber bands on your fingers, then expand and contract them. This will contribute to myofascial (肌筋膜的) release and getting your hands to feel more comfortable.To get a better sense of how much pressure you should apply when touching things, do hand exercise in sand. 17 But when you do hand exercise inside of a sandbox, put your hands in a box of sand, you can literally learn to squeeze the sand and understand which joint or which finger is giving more giving more pressure or less pressure.18 Practice leaning into them with your palm down on the floor. Then, practice leaning into them with the backs of your hands on the floor, rolling on them, like putting weight on and taking weight off the wrist.Finally, try seated eccentric (偏心的) wrist extension. Sit upright with an arm on a table, holding a dumbbell with your hand hanging off the edge and your palm facing down. Use yourother hand to curl your wrist up, lower it, and repeat. 19Don’t overlook the value of overall body health when it comes to improving skillfulness, either. Rojas pointed out that without the optimal gross (最佳的粗肌) and fine motor skills, which make up the skillfulness of our hands, we would be unable to perform daily tasks.A．It sounds strange.B．Moreover, it helps you have fun, too.C．Here are the ones that he recommended.D．To strengthen your wrists, do wrist mobility drills.E．Do this in sets of two with 20 repetitions each, every day.F．To strengthen your sensation of touch, avoid working out with gloves.G．To start with the basics, flexibility is the skill of performing tasks, particularly with your hands.二、完形填空Alfred Nobel became a millionaire and changed the ways of mining, construction, and warfare as the inventor of dynamite (炸药).

This Switch letsyou network up to eight devices at speeds up to 2000Mbps (at full duplex) and is compact enough to beplaced virtually anywhere in your home or office. Add a computer, printer, NAS storage device, or networkcamera and expand the functionality of your network. You may also connect the Switch to hubs, switches,and routers to expand your network.DGS-108 8-Port Gigabit Desktop Switch Wall Mount KitPower AdapterD-Link Green Technology implements special power-saving features that detect cable length and linkstatus and adjust power usage accordingly. Green Technology saves energy in two specific ways:1. If there is no link on a port (when there is no connection or the device connected is turned off) theport(s) will enter a “sleep mode” which will drastically reduce the amount of power used.2. D-Link Green Technology detects the length of connected Ethernet cable and adjusts powerusage accordingly without affecting performance. This way, a port connected to a 10m or undercable only uses as much power as it needs, instead of using full power, which is only needed for100m cables.This product is IEEE 802.3az Energy Efficiency Ethernet compliant. The IEEE 802.3az EEE standard definesmechanisms and protocols intended to reduce the energy consumption of network links duringperiods of low utilization, by transitioning interfaces into a low-power state without interrupting thenetwork connection. Both connected devices must support 802.3az EEE for power saving support. If theconnected device does not support 802.3az EEE, the switch will default to D-Link’s Green Technology ofpower saving.D-Link Green TechnologyPower Indicator - This green indicator light is on when the Switch is receiving power; otherwise, it is off.Link/Act - This LED indicator light is green when the port is successfully connected to an 1000Mbpsdevice and will blink as data is transmitted or received.This LED indicator light is amber when the port is successfully connected to an 100Mbps or 10Mbpsdevice and will blink as data is transmitted or received.LEDsConnecting the SwitchStep 1Plug the supplied power adapter into the Switch and the other end into a power outlet, power strip,or surge protector (recommended). Verify the Power indicator is lit on the Switch.Step 2Connect one end of an Ethernet cable in the device you want to connect to the Switch and the otherend into one of the Ethernet ports on the Switch. Check the Link lights (LEDs) on both the Switch andthe device to verify that the cable is good and that there is a valid connection.Note: A Category 5 (or higher) Ethernet cable must be used for 100Mbps or higher operation.DGS-108• You may mount the Switch on a wall with the included mounting kit.
