BACK TO THE FUTURE WITH ONE-PAIRED ETHERNET 10 MB / S - PETER JONES, ETHERNET ALLIANCE AND CISCO
It's hard to believe, but Ethernet 10 Mbps is again becoming a very popular topic in our industry. They ask me: "Why are we returning to the 1980s?" There is a simple answer, and for those of us who worked in the industry at the time, it is well known. In that era, before Ethernet became ubiquitous, networks looked like the wild west. Each had its own protocols, physical layers, connectors, etc. However, since then, IT has focused a basic set of technologies in the direction of Ethernet, which provides uninterrupted communication for billions of people.

The 10 Mbit / s Ethernet (10SPE) single-pair network was approved by IEEE in November 2019, adding two new physical layer specifications to support data and power per 1000 m copper cable with one twisted pair, as well as multi-channel connection with 8 nodes on 25 m cable . These attributes make it uniquely suited to enable Ethernet within buildings and industrial automation networks. The Advanced Physical Layer (APL) project is based on 10SPE for use in hazardous areas.10SPE was designed to meet the needs of users in the field of building and industrial automation and simplify and accelerate the transition to Ethernet. This makes adopting existing network protocols and services an easy-to-solve problem, allowing the OT world to access the benefits of 30 years of IT innovation. Now the industry has the opportunity to build a single common network infrastructure for facilities.In the year that Ethernet turns 40 years old, I have been inspired by speed since the first days.ETHERNET: GLOBAL CONNECTION TECHNOLOGY - NATAN TRACY, ETHERNET ALLIANCE AND TE CONNECTIVITY
2020 will bring another evolutionary step in the growth and dominance of Ethernet as a global communications technology. The same underlying technology that provided cost-effective LAN communications in the office sector 40 years ago continues to be used in new markets as everyone wants to benefit from the cost, performance and flexibility that Ethernet offers.

For industrial, commercial, automotive, and home applications, we’ll see an extension of the indicated Power over Ethernet (PoE) performance as new PoE options are documented and marketed for a wide range of new applications and systems - from smart buildings to home appliances and the Internet of things, sensors and controls. To ensure that PoE products sold as meeting these performance levels have been verified by certified third-party labs, the Ethernet Alliance will deploy the next phase of the PoE certification program. Another area of rapid adoption of new Ethernet technology is applications,providing the ability to connect our homes and enterprises to the core network through the development of the next generation Passive Optical Network (PON) technology, which will provide aggregate speeds of 50 Gbps over networks reaching at least 50 km.New higher Ethernet data rates will also enter the market to meet the needs of new video-intensive applications available over cloud networks. To match data rates such as 100 Gb / s, 200 Gb / s and 400 Gb / s, technologists are developing new materials and new architectures that will allow these speeds to overcome what was impossible in the past. Using powerful modeling tools and drawing on past experience, but with new materials, we will see Ethernet equipment, optical modules, connectors and cables that allow data center operators in hyper-scaling or the cloud to scale up to new levels of performance and provide new services.Indeed, 2020 will be not only the year when IEEE 802.3 is 40 years old, but also the year of continuous expansion and growth of Ethernet applications, performance and next-generation data rates.ETHERNET'S EXTENSION TO NEW MARKETS - JIM THEODORAS, ETHERNET ALLIANCE AND HG GENUINE USA TO CONTINUE

In more detail, 2020 will be another milestone for Ethernet with the advent of the 112 Gb / s product line. Although 100 Gigabit Ethernet is not new, achieving this speed in serial links not only makes the third generation of cost-effective 100 Gigabit Ethernet products available, but also provides the second generation of 400 Gigabit Ethernet and the first 800 Gigabit per second. In the Ethernet ecosystem, everything will have to leap forward to work faster, wider, and in a more complex modulation format. The first generation of 400-gigabit client optical transceivers based on 8x28Gbaud PAM4 will begin shipping. At the same time, the first 800 Gigabit / s clients will be demonstrated in 8x100 Gigabit Ethernet and 2x400 Gigabit Ethernet.The promise of cheaper serial links in the form of the 400G-ZR should finally be realized.Since most optical transceivers and active optical cables are consumed in local area networks, it only makes sense to minimize overhead and directly connect the optics to the silicon ICs inside these fibers. Jointly packaged optics are far from ready for production, but by 2020 very important work will be done behind the scenes, as the Ethernet industry shifts its technical power, as well as development funds, in the direction of integrating optical communications directly onto a silicon matrix.ETHERNET ECOSYSTEM AND CLOUDING MACHINE - ROB STONE, ETHERNET ALLIANCE AND BROADCOM
The growth in global network bandwidth in all sectors is traditionally due to two main factors; adding users and adding new applications. Despite the fact that the number of users continues to grow, it is overshadowed by bandwidth requirements arising from new applications, which ultimately require the use of new network technologies to meet demand. One of these application classes that has been driving exponential growth in recent years is artificial intelligence and machine learning (ML), in particular convolutional deep neural networks.

To speed up the learning process of ML, parallelization is used involving several separate learning nodes. This leads to stringent network requirements for the distribution of training data between nodes, as well as during the subsequent training process, since the parameters are exchanged between nodes to increase the accuracy of the model. During output, the final application emphasizes the quick return of the result to minimize the delay visible to the end user, and therefore low latency is critical. For these reasons, all major hyper-scale operators have now deployed their own ML hardware, and some offer cloud-based ML as a service for end-user applications.The competition between different ML cloud services forces operators to continue to invest in network infrastructure upgrades in order to remain competitive, which in turn encourages the Ethernet community to respond to technologies that support increased bandwidth requirements, with problems maintaining an acceptable power and cost profile.However, these internal ML-systems are useless, unless the input data can be collected and sent to the inference mechanisms for making forecasts. Devices such as autonomous vehicles, industrial IoTs, and smart homes, offices, and cities use a diverse set of connection technologies, wireless (personal networks, as well as local networks or WiFi), wired, including the use of Power over Ethernet technologies, and cellular communications ( LTE and 5G). All of these technologies make significant use of the Ethernet ecosystem to create cost-effective solutions with rich interoperability.
