Assuming no other architectural changes in deployment, this overlay demonstrated a significant growth lag between 800GbE and the observed growth curves. However, the 4× growth curve generated by a 1.6TbE solution would also lag all observed growth curves, except “Peering Traffic”. Furthermore, all of the underlying factors that drive a bandwidth explosion, including (1) the number of users, (2) increased access rates and methods, and (3) increased services all point to continuing growth in bandwidth.

  • 100 Gigabit Ethernet—Fundamentals, Trends, and Measurement
    100 Gigabit Ethernet— Fundamentals, Trends, and Measurement Requirements By Peter Winterling Nearly every two years, a new hierarchy level is announced for telecommunications. The introduction of the 40 Gbps technology has dominated telecommunications for the last two years and now everyone is talking about 100 Gbps as the next generation. On the surface, everything looks simply like a change of generations is taking place and 40 Gbps seems to be outdated already. However, the introduction of 100 Gbps technology is quite different from the introduction of previous generations. If we look at this more closely, the terms 40 Gbps and 100 Gbps are general terms for comprehensive technological changes in transmission technology. Particularly during this phase of implementing new technology, measurement technology plays an extraordinarily important role. The transition from Gigabit Ethernet (GigE) to 10 GigE brought Ethernet technology to transport networks and, from the aspect of the transmission protocol, this represented a more important milestone than the introduction of the 100 GigE technology. The standardization is still not finalized; however, no significant changes relative to 10 GigE technologies are expected. Anything revolutionary will be determined by physical parameters. It was clear with the 40 Gbps technology that transmissions in existing transmission infrastructure are possible only with substantial modifications to the optically transmitted signal and path. Now, all possibilities must be exhausted for the transmission of 100 GigE (OTU4) in Wide Area Networks (WANs). Standardization for 100 Gigabit Ethernet Three organizations are involved in the standardization for 100 Gigabit Ethernet. IEEE’s Higher Speed Study Group (HSSG) defines the Ethernet specifications under the term 802.3ba.

Fabrega Dept. de Ingeniería Telemática Telefónica I+D Centre Tecnològic de Telecomunicacions de Universidad Carlos III de Madrid Madrid Spain Catalunya (CTTC/CERCA) Madrid, Spain Castelldefels, Spain [email protected] Abstract— This paper provides a short overview of 5G Distributed Unit/Central Unit (DU) over the fronthaul (FH) fronthaul transport and analyses the opportunity of using a new network. Conversely, the DU must synthesize the baseband generation of SBVT (Sliceable Bandwidth Variable Transceivers), signal to be upconverted and radiated by the antennas; this signal for this purpose. is transmitted over the fronthaul network to the RU. Keywords—fronthaul, C-RAN, sliceable bandwidth variable This approach distributes the functionality of the base station transceiver (SBVT), xhaul and the actual remote radio head in the field becomes simpler. Furthermore, it enables signal processor sharing by the massive I. INTRODUCTION deployment of antennas expected for 5G and beyond. Figure 1 After over a 10-year period of intense research and shows the main splits considered by 3GPP and the usual standardisation effort in the design of fronthaul traffic transport distribution of functionalities among RU, DU and CU (Central [1]. a number of tradeoffs, advantages and limitations of the Unit). studied technologies have been identified.

  • 2015 Ethernet Roadmap
    The 2015 Ethernet Roadmap Contributors: John D’Ambrosia, Dell Scott G. Kipp, Brocade Executive Summary Ethernet has always been about innovation, and, still today, the global ecosystem of Ethernet stakeholders leans forward into the visionary questions, What more can Ethernet do, and what else can the world do with it? However, never in Ethernet’s 40 years plus have those questions touched upon so many nuances across markets, requirements and applications. Now that Ethernet is in its 40s, the leading networking technology in the world is embracing a diversity of applications. In 2010, the Ethernet standardization community broke from its history of boosting the technology’s highest speed strictly by a factor of 10. Today—with adoption fervent on a number of diverse fronts including automotive networks, power, industrial control, next-generation and residential access and server connectivity in hyperscale data centers—Ethernet is embracing the fact that there are now considerable and substantial markets that are growing in their own ways and paces that simply cannot be ignored. The result is that the proven technology is amid a period of multi-faceted innovation, without betraying any of the core characteristics that have driven Ethernet’s emergence over the last four decades. Ethernet is developing four new Ethernet speeds—2.5, 5, 25 and 400 Gigabit Ethernet (GbE)—to add to the existing six speeds— Megabit Ethernet (MbE), 100MbE, GbE, 10GbE, 40GbE and 100GbE). Over the next decade, several more speeds are being considered, including 50GbE, 200GbE and multiple speeds beyond 400GbE. Together, these speeds define the core of the 2015 Ethernet Roadmap.
