Ccie lab dumps From 1 to 5, how to face 5G and its challenges (2)

Second, 5G has four important features

5G has four important features: high speed, ubiquitous network, low power consumption, low latency. I will talk about these four characteristics today.ccie lab dumps

1. high speed

We can clearly feel that when I 3G, I took a mobile phone to download a picture, and the 2M picture could not be downloaded for a long time.ccie lab dumps.When it comes to 4G, not only can it be second, but there is also a big change:For example, if you open a video with WeChat, it will start playing automatically when you open it, and 3G will not play automatically.4G doesn't matter, just play it, what changes will happen in the 5G era?

VR used to be particularly hot, but why can't VR do it? Because with VR, the experience is very slow, the effect is very poor, and it will be dizzy after a while. Because VR requires at least 157M speed, and now 4G speed can not reach.


2,ubiquitous network

Ubiquitous network means that there is a network in every corner of social life. You may think, do we really need this? The answer is needed.


For example, an underground garage is needed.Smart car, it runs outside for one day, and goes back to charge at night. It has to stop in the parking space of the underground garage and plug it in. If you can find your own parking space without network, how can you plug in the charging head?

3. low power consumption.

We all wear smart watches, but wearing smart watches is painful now, because we have to charge every day, we must hope that it will be charged once a month. How can it be done? It must be done with low power consumption.

Belt, if it is connected, can record my waistline, record my body movements, recently fat or thin.My glasses should also be networked, it can record my lacrimal gland and many things I see.ccie lab dumps.All these things must be intelligent and networked, it is troublesome: go home every day, the belt is untied and charged, the shoes are taken off and charged, the glasses are taken down and charged, then we simply don't want to use them. Therefore, it is necessary to reduce the power consumption and charge it up to one month.

4. Finally, talk about low latency, which is the most important feature of 5G.

How do we usually convey the voice of our speech? The speech vibrates the air, and the two people pass each other, and the time of transmission is 140 milliseconds.140 milliseconds humans can tolerate, we never feel how much delay.But if you control a drone or control a car, give the car a brake signal,is the car need 140 milliseconds to react, it ran 200 meters. Ccie lab dumpsIf it was 20 milliseconds, it ran for more than a dozen meters. This kind of thing is impossible to make the driverless car a reality.The vision of the new World Telecommunication Union 5G is to achieve 1 millisecond, or even less than 1 millisecond, such a response to the current network and technology can not do.Therefore, solving the problem of delay is the core problem in the communication system.

The mobile network infrastructure has undergone tremendous changes in just a few years.For example, the evolution from 3G to 4G enables mobile infrastructure to offer consumers new data-centric services such as rich multimedia and enhanced content features and services.

Third, how to face the challenges brought by 5G

5G will enhance the power and capacity of mobile networks to better support end-to-end environments, enabling our society to move and connect completely.Advances in virtualization, automation, and orchestration, coupled with new 5G networking capabilities, will bring data and transaction decisions closer to the edge of the mobile network—the edge cloud.ccie lab dumps.It will allow organizations to redesign their infrastructure to better meet the needs of digital transformation. Data and calculation requests have been passed back and forth from the core for execution and can now be processed and executed at the edge.This enables organizations to greatly enhance their ability to scale and increase the speed at which decisions and transactions are completed. With edge clouds, innovation will no longer be limited by central data centers and public/private clouds.

5G network is changing business

The telecommunications industry has begun to transform its business by taking advantage of these new opportunities, and of course they are only the first. This will be the actual method of the next network computing cycle.ccie lab dumps.5G connectivity and edge-based computing will enable digital transformation, delivering exponential growth in service and productivity for businesses, and improving quality of life and highly customized and personalized experiences for connected consumers and citizens.The high-speed, low-latency nature of 5G also means that the "always on" business model can now be implemented without geographical constraints - away from enterprise data centers or cloud platforms.Ultimately, hyper-connected devices with edge clouds will no longer be limited to the cloud, but will become a new super-cloud in which applications, data and services will run across the edge of the network.

Due to its enhanced performance, 5G is complementing wireless connectivity from wired networks and centralized processing, and will support a wide range of new Internet traffic from developing IOT/IIoT sensors, devices and connectivity platforms.Connecting cars from headless sensors, different use cases are entering a new hybrid city that enters an umbrella network environment where physical and critical infrastructure is directly interconnected.

5G impact on security

With 5G technology in place, end-to-end innovation—whether technically or on the network architecture that supports it—will quickly transform mobile infrastructure into a platform and catalyst for value creation and service innovation.5G's "flat" architecture may increase the risk of cyber attacks on mobile infrastructure, especially if they are now part of the end-to-end IP core infrastructure.ccie lab dumps.This extended attack surface will consist of thousands or even millions of interconnected nodes that are vulnerable to attack and abuse.Due to these vulnerabilities and the transition to the edge cloud, end-to-end security from the mobile core to the edge is imperative. This will drive the need to embed security features and functionality directly into the edge, far beyond the typical state of "fixed" to traditional networks.

Organizations can't wait to develop a strategy. They need to start planning now to ensure they have the technical and human resources to support and protect their 5G opportunities. Only a fully coordinated security strategy can protect future high mobility and dynamic networks and devices. And business.
