Smart devices are constantly coming into the market, and their growth prospects are amazing. According to research firm estimates, by 2020, the number of connected Internet of Things (IoT) devices will reach 214 billion. The increasingly serious problem that network architects and administrators need to face together is: How can we effectively manage the data tsunami that is about to hit?
The era of mobile intelligence has arrived
Mobile intelligence has changed almost everything, but what really makes the magic in the bottle free is the development of wireless connectivity technologies such as Wi-Fi® and Bluetooth® Smart. Today, smartphones, laptops, tablets, and other mobile devices provide enough data processing power to run countless smart devices. In fact, technology is around us and has even entered our bodies.
The technology of wearable devices is booming like the fire of the original, such as smart watches and smart bracelets, which not only can be good for health, but also help users achieve fitness goals. At the same time, medical and health technologies are constantly evolving, such as micro-implants, which can sense impending heart disease and can seek help by alerting them to smartphones. For smart products that can be monitored, read, perceived, tracked, reported, and alerted, the home environment is another hot market. Therefore, whether it is through entrepreneurial companies raised by crowdfunding or Fortune 500 companies, the opportunities brought by smart devices are everywhere.
Inevitable network stress
As billions of devices continue to generate and consume fast and efficient data transfer, the pressure on the network can be imagined. According to the Cisco Global Cloud Index, by 2017, the global data center's annual IP traffic will reach 7.7 terabytes (1 zebyte is equivalent to 1 byte multiplied by 10 to the 21th power). Will produce a huge amount of data.
Fortunately, the widespread adoption of Ethernet connectivity has brought tremendous advantages. As a standard that has been trusted for decades, Ethernet not only provides the Internet of Things, but also provides a secure underlying network layer for operating systems and software applications running the Internet of Things. Highly scalable Ethernet has expanded from 10 Gigabits per second (Gbps) to 40 Gigabits per second (Gbps) and is moving toward 100 Gigabits per second (Gbps).
Connect to the line with Ethernet
Undoubtedly, from this point of view, network architecture innovation and powerful new virtualization technologies will redefine the way the data center operates. However, given that Ethernet plays a key role in this unprecedented network construction, the Internet of Things may be more of an "Ethernet of Things":
Service provider network
Today, Ethernet has become the technology of choice for building service provider networks. Wireless backhaul, broadband aggregation, metropolitan area networks, and core networks all rely on Ethernet high-speed, low-latency, and cost-effective features to carry increasing traffic loads. What's more, the Ethernet business architecture connects devices to data centers that provide application and analytics, enabling a highly flexible architecture to handle the growing bandwidth demands.
Software Defined Network (SDN)
The emerging SDN architecture separates the network control and forwarding function (forwarding funcTIon), which helps administrators directly program network control and extract the underlying infrastructure for applications and network services. At the same time, the SDN software program enables rapid network configuration, management, protection and optimization, and adjusts traffic based on changing needs. This "centralized intelligence" can provide a global view of the network, making it logically a single switch for the application and policy engine. In addition, open standards and vendor-neutral low-cost SDN can simplify network design while improving manageability, coordination, and control. As an important backbone of the Internet and data center, programmable, low-latency, high-performance Ethernet switches are ideal for SDN.
Network Function Virtualization (NFV)
Complementing the SDN architecture, NFV is a new way to design, deploy and manage network services. Specifically, NFV enables all types of network functions to be independent of proprietary hardware applications such as routers and switches so that they can run on software. Using standard IT virtualization technology, NFV can "virtualize" these functions into building blocks and create communication services over the connection. NFV is applicable to any data plane processing or control plane function in wired and wireless network infrastructure. Therefore, Ethernet networks are more scalable, agile, and efficient.
cloud computing
Virtualization of networks, storage, and servers is reshaping the way organizations use IT. In this process, cloud computing plays a key role in providing Internet access for complex applications and large-scale computing resources. At the same time, the “cloud†can provide additional capacity to meet the growing demand of third-party companies or small businesses, enabling organizations to achieve greater capacity without investing in new IT infrastructure. By hosting data and data processing in the cloud, administrators are free to provision capacity to the geographic location where data is created and control the devices that generate the data. A well-designed Ethernet network delivers the low latency and high bandwidth required for cloud computing, leveraging the value of its high efficiency.
Big Data
As more data is connected to the Internet and interconnected, today's data management tools and traditional applications will not be able to accurately analyze the need for "big data" (the growing large-scale complex data set). Innovative technologies such as SDN, NFV, and cloud computing are gradually merging into a new way to enable networks to capture, refine, manage, and process big data in an acceptable runtime. With its high bandwidth and low latency, Ethernet is once again ideal for connecting servers that handle big data.
Green data center
As the size and complexity of data centers continue to increase, energy costs continue to rise and their efficiency is severely affected. According to The New York Times, 90% of the electricity that data centers receive from local power facilities in 2012 may have been wasted. The use of more energy efficient, higher speed Ethernet connections will be of great benefit to building energy-efficient and environmentally friendly data centers. According to research, if you use 1GB of Ethernet and switch to 10GB of energy-efficient Ethernet, you can reduce carbon dioxide emissions by up to 3.5 million tons, reducing consumption of 1.3 billion gallons of gasoline and 27 million barrels of crude oil. The energy saved by the decommissioning of 2.3 million vehicles.
The Ethernet stage has been opened
Combined with 10 Gigabit or higher Ethernet connectivity, SDN, NFV and other network automation tools provide a highly dynamic, highly agile and efficient network foundation for the operation of the IoT device software layer. Wireless connected devices can also effectively complement the physical network by extending the network connection.
With the full development of the Internet of Things revolution, these unique technologies and other innovative technologies will gradually be in place. Ultimately, it will ensure that end users can maximize the benefits of hundreds of billions of products and devices.
