    5G motivates the edge computing progress. Higher rate and higher density optical transceivers will be required. Edge computing is the leading-edge technology for the next-generation data center. In the current period, edge computing is in the period of practice. It is important that how to develop edge computing and how to meet the needs of edge computing. On Jun. 25, 2019, the OCP China Day hosted in Beijing, China by one OCP Platinum member, Inspur. The distinguished guests from Microsoft, Facebook, LinkedIn, Baidu, Tencent, and Inspur attended the conference. They share vital topics such as artificial intelligence, edge computing, and SONiC about various leading-edge technologies here. Among these topics, edge computing has been frequently mentioned, here we will discuss the development of 5G and edge computing.

  • Progression from 4G to 5G

    5G, the latest advancement in cellular network evolution, promises pioneering improvements in availability, reliability and performance requirements of the emerging applications in the enterprise segment. Standard bodies like ITU and NGMN have come up with multiple use cases for 5G. Each of these use cases differ in terms of expected data rates, latency, reliability and availability. Hence, they need different treatments by the underlying cellular networks. This article discusses such use cases, shortcomings in 4G to realize these use cases and how 5G promises to handle their stringent requirements. The article further attempts to show a high level migration from 4G EPC to 5G core network—mapping their network components with respect to functionalities. 5G Usage Scenarios Based on the requirements from the wireless networks, the 5G use cases are classified into three main categories: Enhanced Mobile Broadband (eMBB): These scenarios require 5G cellular networks to support very high data rates. 5G performance targets recommended by ITU suggest, peak data rate of 20Gbps in downlink and 10Gbps in uplink. In dense areas, it expects a throughput of 10–100Mbps/m2. Ultra-Reliable and Low…

  • Why 5G Wireless Will Leverage High-Speed Optical Networks and Machine Learning

    At this year’s Optical Fiber Conference (OFC) in San Diego, CA, we saw how advances in cognitive Software-Defined Networking (SDN) and fiber-optic electronics are enabling the rollout of 5G mobile wireless, which in turn will deliver new services such as augmented reality, drones, industrial IoT, self-driving vehicles and massive connectivity. OFC is an annual conference sponsored by two IEEE societies: the IEEE Communications Society and the IEEE Photonics Society, as well as the Optical Society. This year’s event brought together 15000 attendees and nearly 700 exhibitors, who showcased the latest products in the growing optical-network infrastructure market, along with SDN solutions. This year’s show highlighted the convergence of electronic, optical and wireless technologies that will support the growth in connectivity and network traffic over the coming decade. New services like self-driving vehicles demand higher capacity in the fronthaul, backhaul and metropolitan optical networks that connect 5G wireless access points with data centers. Alex Jinsung Choi, a senior vice president at Deutsche Telekom, explained at OFC that “5G network operators must deliver 100Gb/s connectivity to the base station to support the…

  • Ethernet for 5G Fronthaul

    5G promises to deliver higher speeds and support revolutionary new use cases, services and applications that connect people and things. No previous RAN technology has been expected to support such a wide range of services with different capacity, latency, synchronization, reliability and connectivity requirements. Operators cannot meet these expectations by building the 5G RAN in isolation from other network domains, including the transport layer. Besides the upgrades to the RAN—which include cell densification, more antennas (i.e. massive MIMO) and the use of existing and new operating frequencies—operators need more fiber and new packet transport technologies that address the diverse applications and corresponding network requirements. Where possible, their 5G plans should leverage existing packet networks to save on cost and speed deployment. 5G was not intended to operate independently or replace existing 4G networks. Rather, 5G radios were engineered to complement existing resources. This is evidenced by a thrust of non-standalone (NSA) configurations in early deployments where the 5G radios attach to the 4G packet core network and use 4G LTE for coverage and 5G for capacity infill. Having overlay networks…

  • 10 Tips You Should Know About 5G Network

    No.1 5G does not mean traffic, but the Fifth Generation of Communication Technology. No.2 If 3G is a single lane, 4G may be three lanes, 5G is ten lanes or more, and there are special lanes. 5G high-speed dedicated channels can generate many innovative personal applications and industry applications. No.3 In the 5G era, the Ready Player One is no longer a movie but a reality. In terms of industry, medical assistance can be more effective. In the future, ambulances can be turned directly into emergency rooms, and experts in hospitals can perform real-time online rescue and surgery. No.4 Where 5G is powerful—stability. Single brand products can have dedicated channels. There will never be any break or delay. No.5 5G can support 8K UHD video transmission. Virtual reality brings a thing far away from you to your face. No.6 The 5G technology is not aimed at ordinary people, but the industry. No.7 Don’t worry that mobile phones will be out of date. Now only the 5G core standards have been set down, other research and development and equipment and so on…

  • The Technical Path of 5G Needs to Be Clarified Urgently

    5G has defined three use cases, and each requires a technology phase not less than 5 years. Assuming the deployment of 5G begins in 2019, it might take more than 10 years to achieve the 5G network in our imagination. We have to analyze the feasibility of technology and application, so as to provide a basis for the rethinking of superstructure. The Three Use Cases of 5G The first use case of 5G is eMBB, short for Enhanced Mobile Broadband. It is defined to achieve Virtual Reality (VR) technology and Ultra-High Definition (UHD) video sharing, cloud access anywhere and up to 1Gbps of Internet bandwidth. The second use case of 5G is uRLLC, short for Ultra Reliable Low Latency Communications. It includes low latency automatic driving and industrial Internet etc. The last use case of 5G is mMTC, short for Massive Machine Type Communication). It is defined to realize vehicle networking and intelligent asset management, that is, to make Internet of Everything (IoE) become a reality. The three use cases of 5G have covered every technology field that human technology…

  • QSFP-DD Might Be the Mainstream Form-factor of 400G Optical Transceivers

    Time to enter 2019, when 400G has become a hot topic in the optical communications industry, the world’s leading optical transceiver manufacturers have launched their own 400G optical modules. When we list the form-factors of these manufacturers’ 400G optical modules (as shown in the figure below), we found that all the manufacturers except the Finisar (acquired by II-VI) have adopted the QSFP-DD form-factor — the market seems to have recognized QSFP-DD as the first choice for form-factors of 400G optical modules, though some manufacturers have also introduced 400G optical modules with OSFP and CFP8 form-factors. 400G Form-factors of Mainstream Optical Transceivers Manufacturers Tips: QSFP-DD is a high-speed pluggable module form-factor defined by the QSFP-DD MSA group. The QSFP-DD MSA group has defined the next generation, high-density, high-speed pluggable module form factor that addresses the industry need for high-density, high-speed networking solutions in a backward compatible form factor. The QSFP-DD Specification has been developed and refined by many companies within the QSFP-DD MSA group and released to the public. Why do mainstream manufacturers choose the QSFP-DD form-factor? Does this mean that the…
