Networking trends for 2018

Here are some of my collection of newest trends and predictions for year 2018. I have not invented those ideas what will happen next year completely myself. I have gone through many articles that have given predictions for year 2018. Then I have picked and mixed here the best part from those articles (sources listed on the end of posting) with some of my own additions to make this posting.This article contains very many quotations from those source articles.

Big Data, mobility and the Internet of Things (IoT) are generating an enormous amount of data, and data center operators must find ways to support higher and higher speeds. Recent data center trends predict bandwidth requirements will continue growing 25 percent to 35 percent per year. Many older data centers were designed to support 1-gigabit or 10-gigabit pathways between servers, routers and switches. Today’s Ethernet roadmap extends from 25- and 40-gigabit up through 100-gigabit, and 400-gigabit and even 1-terabit Ethernet loom within a few years. The biggest sales are forecasted for 25G and 100G ports for next few years. Ethernet switch market has now 100 Gbit/s products in the volumes at the moment, and both 200G and 400G Ethernet versions will be taken to use in 2018.

Broadcom dominates the Ethernet switch chip market today with a 73 to 94 percent share, depending on how market watchers slice the sector valued at nearly a billion dollars. Its closest rival, Cisco Systems, takes most of the rest with systems using its own ASICs. Juniper, Hewlett Packard Enterprise and Huawei also make Ethernet switch ASICs for their systems. With seven merchant chips in the pipeline and four in-house ASICs in the works, we will see a record number of unique platforms ship in 2018. Wheeler of the Linley Group expects the competition will drive Ethernet switch costs from about $60/port today to about $36/port by 2020.

Data center giants “are driving their own code and programmable capabilities as close to the server as possible.The dozen largest data center operators — including the likes of Facebook and Google — build their own switch systems or specify systems built by ODMs. They can drive sales of millions of chips a year but demand maximum bandwidth at minimum cost and power consumption. The Tomahawk-3 is geared for the next-generation of their top-of-rack and aggregation switches, delivering up to 128 100GE or 32 400GE ports, the first merchant chip to support 400GE rates.

China will start making more optical components: Several Western component and subsystems vendors have cited reduced demand from Chinese systems houses such as Huawei and ZTE for revenue declines in 2017. One reason for the slowdown is the fact that these systems houses have begun looking for more local optical technology sources. In addition to doing more development work in-house (particularly in the case of Huawei), the two Chinese systems vendors have begun to work more closely with Chinese companies such as Accelink, Hisense, and HiSilicon as well as Japanese vendors. This can mean that Western firms (particularly in the U.S.) may not see their Chinese orders return to previous levels.

Higher power power over Ethernet: 802.3bt – IEEE Draft Standard for Ethernet Amendment: Physical Layer and Management Parameters for DTE Power via MDI over 4-Pair amendment to IEEE Std 802.3-2015 increases the maximum PD power available by utilizing all four pairs in the specified structured wiring plant. This represents a substantial increase to the capabilities of Ethernet with standardized power – allow delivery of up to 90 watts of power via existing Ethernet cabling. The Ethernet Alliance has announced details of its next plugfest: Dedicated to pre-standard testing of Power over Ethernet (PoE) technologies against Draft 3.2 of the IEEE P802.3bt standard, the event will be held in February 2018. The specification’s ratification is expected in September of 2018.

802.11ax hasn’t been signed off yet, but promises to send WiFi towards 10 Gb/s thanks to its use of both multi-user multiple-input and multiple-output (MU-MIMO) and the new Orthogonal frequency-division multiple access (OFDMA). 802.11ax is  good at combining lots of different links so that users get more connections, more often, and end up with more bandwidth.  Marvell claims it’ll have the first chipsets for new 10G WiFi ready for products in H2 2018. Marvell said the chipsets will ship some time in early 2018 and will appear in products in the second half of the year. Widespread 802.11ax adoption in devices probably won’t happen until 2019.

5G something in it for everyone. 5G is big.  5G New Radio (NR) wireless technology will ultimately impact everyone in the electronics and telecommunications industries. Most estimates say 2020 is when we will ultimately see some real 5G deployments on a scale. In the meantime, companies are firming up their plans for whatever 5G products and services they will offer. Though test and measurement solutions will be key in the commercialization cycle. 5G is set to disrupt test processes. If 5G takes off, the technology will propel the development of new chips in both the infrastructure and the handset. Data centers require specialty semiconductors from power management to high-speed optical fiber front-ends. 5G systems will drive more complexity in RF front-ends .

Networks will become more and more virtual, especially on 5G. 5G networks will build on LTE network architecture with the introduction of cloud RANs (C-RANs) and virtualized RANs. Network function virtualization (NFV) and software-defined networking (SDN) tools and architectures could enable operators to reduce network costs and simplify deployment. For more details read System architecture milestone of 5G Phase 1 is achieved article.

Automotive Ethernet: Automotive Ethernet will replace the Media Oriented Systems Transport (MOST) bus found on many vehicles today and also compete with systems like Maxim’s Gigabit Multimedia Serial Link (GMSL). The standards include IEEE 802.3bw 100BASE-T1 and IEEE P802.3bp 1000BASE-T1 that adopt the 100-Mb/s and 1-Gb/s Ethernet protocols to run over over a single twisted pair up to 15 meters. Chips, PHYs and switches are now readily available for automotive Ethernet. Automotive switches will support time-sensitive networking (TSN) features like audio video bridging (AVB) ingress policy, rate limiting andalso features 802.1Qav/Qbv queue-shaping support. We will need a Security Blanket for Automotive Ethernet.

Car-to-car communication: The industry and government have defined several versions of vehicular communications. These are vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), and vehicle-to-everything (V2X). V2V is the direct communications between vehicles within range of one another. V2V link-up is automatic and cars exchange status information messages Basic Safety Message (BSM) 10 times per second (contains data such as GPS location, speed, direction, brake status, and related conditions). There are competing technologies to make this all work. IEEE802.11p ahead of LTE-V2V for safety critical applications. 5G will offer increased capacity and decreased latency for some critical applications such as vehicle-to-vehicle (V2V) or vehicle-to-infrastructure (V2I) communications for advanced driver assistance systems (ADAS) and self-driving vehicles. The big question is whether 5G will disrupt the landscape or fall short of its promises.

TSN (time sensitive networking) will be talked on many application. Success in the IIoT requires that information- and operational-technology networks work in tandem—time-sensitive networking can make it happen. A converged industrial network will address several challenges that currently exist in today’s disparate network architecture, and it is believed that needed convergence is provided by time-sensitive networking (TSN). TSN is a set of IEEE 802 sub-standards that, when implemented, enable deterministic communication over Ethernet networks while keeping the benefits of communication in best effort manner, on that same network. TSN introduces different traffic classes that share the same link. Proper implementation of TSN requires a solution that can provide a low latency and deterministic response at TSN end points and TSN bridges – it is usually implemented with combining a processor and a FPGA or using advanced Ethernet switch chip.

Gartner analyst says on-premises data centers will soon be ‘useless’: Govekar said that as soon as 2019, at least a third of the largest software vendors will have transitioned their products from cloud-first to cloud-only. For this reason Gartner analyst predicts doom for on-premises data centers. If this happens , there will be a lot of work for network operators and cloud service companies to be able to build the infrastructure that can handle all this without problems. I expect that not all on-premises data centers are doomed. There are applications where moving everything to central could does not make sense – for example many IoT applications are moving some of the processing from cloud to edge devices for various reasons (lower latency, reduce needed bandwidth, work also when communications does not work etc..). There is also place for some on-premises data centers on some application (may them be depending on need anything from embedded server to room full of equipment racks). When designing for the IoT, security needs to be addressed from the Cloud down to each and every edge device. Protecting data is both a hardware and a software requirement, as more data is being stored and analyzed in edge devices and gateways.

Network neutrality talks will continue in 2018. Federal Communications Commission (FCC) on December 14, 2017 overturned the Title II-based Open Internet Order the previous Democratic-controlled FCC regime put in place in 2015. So what happens next? In the immediate term, nothing. The Restoring Internet Freedom Order won’t go into effect until sometime in the first half of 2018.

IPv6 usage seems to be finally accelerating in 2018. IPv6 has been a “future” since 1998, and an important future since 2007. IPv6 deployments have been increasing and chances are you have already used IPv6 – but haven’t realized it yet. IPv6 deployment is increasing around the world, with over 9 million domain names and 23% of all networks advertising IPv6 connectivity. Network admins will have many concerns about migrating to IPv6 in 2018. China plans to put the Internet Protocol version 6 (IPv6)-based network into large-scale use, to boost the development of the Internet industry. China aims to have 200 million active users of IPv6 by the end of 2018. IPv6 use is increasing, but that does not mean that IPv4 is no way dying. It seems that both of those technologies will co-exist in Internet for a long time.

    China Calls US Concerns Over Huawei ‘Groundless’

    Beijing called the latest US warning against using Huawei equipment “groundless” on Tuesday, as the Chinese telecom giant faces espionage fears in a growing number of countries.

    The world’s second-largest smartphone maker and biggest producer of telecommunications gear has been under fire in recent months after the arrest of a top executive in Canada and a global campaign by Washington to blacklist its equipment.

    “The US has spared no effort in unscrupulously fabricating all kinds of groundless charges,” said Chinese foreign ministry spokeswoman Hua Chunying at a regular press briefing in Beijing Tuesday.

    112G Digs in at DesignCon 2019

    112G serial links have moved out of the lab and onto the exhibit floor. 56G ramps up while 28G goes mainstream.

    Last year at DesignCon 2018, we witnessed high-speed digital designs that moved past 56 Gbits/s (56G) and onto 112 Gbits/s (112G). This year, DesignCon 2019 brought numerous demonstrations of 112G as the connectors and cables caught up with the silicon. While still appearing in technical papers and panels, 112G has certainly moved into the exhibit hall. Meanwhile, 56G has matured and is now a complete ecosystem.

    South Korea is Censoring the Internet by Snooping on SNI Traffic

    South Korea has been blocking HTTP websites that are on their censor list for a while now and they have recently started using SNI filtering to block their counterparts served over HTTPS.

    A warning page bearing the seals of the Korea Communications Standards Commission (KCSC) and the Korean National Police Agency is displayed for blocked HTTP websites, while TLS sites blocked using Server Name Indication (SNI) filtering will only throw a “This site can’t be reached” error.

    SNI filtering used to block websites

    SNI is a TLS extension which allows browsers to inform a web server of the hostname they want to connect to at the beginning of the handshaking process, as detailed in IETF’s RFC3546.

    Russian MPs Back Bill to Isolate Country’s Internet

    Russian lawmakers on Tuesday backed a bill that could cut off the country’s internet traffic from servers abroad which critics say is a step towards censorship and possibly an isolated network like in North Korea.

    The bill passed its first reading by 334 votes to 47 after an unusually heated debate in the State Duma, where many lawmakers from minority parties criticised it as too costly and argued that it was not written by experts.

    Copper Assembly Can Replace Fiber Optics in Some High-Speed Server Applications
    Molex’s BiPass cable assembly can serve in switch-to-server connections at speeds up to 112 Gbps.

    In the ongoing drive toward gigabit speeds in servers and other computing systems, copper cabling has sometimes been written off. That’s especially true now, as engineers charge toward 112 gigabits per second (Gbps).

    But at the recent DesignCon 2019 show, Molex, Inc. demonstrated a cable assembly that could enable hyper-scale data centers to employ copper, instead of expensive fiber optics, in some 112 Gbps applications for switches, routers, and servers.

    Known as BiPass, the cable assembly routes signals directly from an ASIC chip in a switch to the server front-panel I/O without having to go through the printed circuit board that normally resides in between them. “Because it eliminates so much of the loss that you would (otherwise) have going through the printed circuit board, now you can go two-and-a-half to three meters, and all of a sudden, a passive copper link is still viable,” Brent Hatfield, new product development manager for Molex, told Design News. “And at the same time, you don’t have to go to an optical fiber, which would be dramatically more expensive.”

    BiPass accomplishes that by employing a twinaxial copper cable assembly

    In essence, the twinax serves as a shunt around the switch’s printed circuit board, which can be “lossy,” Hatfield said. “As speeds go up, printed circuit board materials tend to have increasing challenges transmitting the signals,” he said. “They have so many traces in there, and the traces can get long. So by the time you get to the front panel I/O, you can lose signal.”

    “The big thing that drives all this is the economics,” Hatfield said. “A good rule of thumb is that if you’re going to have an optic solution, it’s going to be seven to ten times more expensive than copper.”

    Molex actually introduced the BiPass solution in 2017, in anticipation of the coming demand for speeds of 56 Gbps. Now that 56 Gbps is emerging, and the industry has begun looking to the next step of 112 Gbps, the BiPass concept is starting to gain traction, Hatfield said.

    Huawei Backlash: China Accuses ‘Lying’ U.S. Of ‘Unjust And Immoral Bullying’

    The flagship Mobile World Congress event is now just a week away, and when the telecoms industry gathers in Barcelona for its annual show and tell it could be the most interesting one yet. Not because of early-adopter 5G handsets and folding screens, not because of demos of lightning-fast 5G downloads and AI apps, but because it will become the epicenter of a ‘tech war’ between the U.S. and China that has escalated to threaten the best-laid 5G deployment plans of countries around the world.

    Huawei hasn’t yet fixed its security vulns, says UK’s NCSC overseers
    Not secure enough for use either

    Huawei has not showed British government overseers a “credible plan” for dealing with security shortcomings flagged in a report issued last year, the technical director of the National Cyber Security Centre (NCSC) has said.

  12. Tomi Engdahl says:

    Germany tells America to verpissen off over Huawei 5G cyber-Sicherheitsbedenken
    Europeans can’t find any evidence of Chinese spying

    German is expected to snub US pressure to cut Huawei out of its next-generation 5G networks, rejecting claims that the Chinese manufacturer is a security risk.

    Would a Huawei Boycott Unravel the Supply Chain?

    Huawei Technologies Co. — the controversial Chinese vendor of networking gear and smartphones — faces the real possibility that its telecom equipment will be banned from U.S. and European markets. If Huawei’s sales suffer, its supply chain will feel the pain. Huawei became the world’s third-largest semiconductor buyer in 2018, according to Gartner, and almost half its $100 billion revenue is derived from foreign markets.

    Huawei’s ascension on the top buyers’ list underscores a dilemma facing the global supply chain.

    A U.S.-EU Huawei ban would whack component makers with both ends of the stick. U.S. vendors would be cut off from a massive — and growing — global OEM. A boycott of Huawei’s smartphones and telecom equipment would put a considerable dent in its component demand.

    IEEE 802.3 Ethernet Working Group new task forces and study groups: Listed

    Forces, whose efforts continue to drive viable solutions for industry and end users alike. These new efforts include:

    IEEE P802.3cg™ 10 Mb/s Single Pair Ethernet Task Force.

    Automotive and automation industries have begun the transition from legacy networks to Ethernet. As a result, there is a growing need for an intrasystem control 10 Mb/s solution that operates over a single balanced pair of conductors.

    IEEE P802.3ck™ 100 Gb/s, 200 Gb/s, and 400 Gb/s Electrical Interfaces Task Force.

    The continual growth of bandwidth demand has driven evolution of higher Ethernet speeds, most recently with 100 Gb/s, 200 Gb/s and 400 Gb/s Ethernet. To meet this growth, IEEE P802.3ck will support ongoing advancement in serializer and deserializer circuit (SERDES) technology to higher rates of operation that will enable the development of higher density or lower cost electrical interfaces using 100 Gb/s signaling.

    IEEE P802.3cm™ 400 Gb/s over Multimode Fiber Task Force.

    Rapid growth of server, network, and internet traffic is driving the need for higher data rates, higher density, and lower cost fiber optic solutions, especially in the data center space. To address these needs, advances in technology now allow the specification of new 400 Gb/s physical layer types operating over fewer multimode pairs than in existing IEEE 802.3 Ethernet standards.

    IEEE P802.3cs™ Increased-reach Ethernet optical subscriber access (Super-PON) Task Force

    The IEEE P802.3cs Task Force intends to help the fiber optic communication community to reduce cost and complexity in access optical distribution networks. The project aims to define a passive optical network (PON) architecture supporting longer distances between the central office and the customers and an increased number of subscribers per fiber strand through wavelength division multiplexing.

    IEEE 802.3™ 100 Gb/s per lane optical PHYs Study Group

    The IEEE 802 LAN/MAN Standards Committee Executive Committee has chartered this Study Group under the IEEE 802.3 Ethernet Working Group to develop a Project Authorization Request (PAR) and Criteria for Standards Development (CSD) responses for 100 Gb/s per lane optical PHYs for 2 km and 10 km for 100 Gb/s Ethernet and 400 Gb/s Ethernet.

    Why 56Gb/s And 112Gb/s SerDes Matter In Our Daily Social-Media-Driven Lives

    High-speed serial links are critical for the next generation of servers, switches, routers and 5G infrastructure.

    Hyper-scalers and service providers are moving from 100GbE to 400GbE Ethernet rates and beyond.

  17. Tomi Engdahl says:

    Good fiber-optic connections start with the ferrule

    The quality of an optical connection often can be directly traced to the ferrule used in constructing the connector.

    ariance in hole size would allow for minute variations in the manufactured optical fiber cladding diameters. For example, for a 125-µm optical fiber, ferrules are available with hole sizes ranging from 124µm to 127µm.

    Ferrules are manufactured using an injection-molding process of the ceramic. After the initial molding step, the ferrules are put through a precision boring process and then polished to remove any machining marks, nicks or scratches.

    The bore diameter depends on extremely precise and minute factors. Fiber optics is a technology that requires extreme accuracy and attention to detail. If this factor falls short to a tiny degree, loss of light, and therefore data, occurs. The greater the discrepancy, the lower the connectivity performance.

    Law Expert: Chinese Government Can’t Force Huawei to Make Backdoors

    The Sino-US trade war is hurting companies on both sides of the conflict. In early January, the US stock market dropped sharply after Apple issued its first revenue warning in 16 years, citing weak sales in China. Several weeks later, chipmaker Nvidia cut its quarterly revenue expectations by $500 million for the same reason. A survey last year by the US-China Business Council showed that 28 percent of US companies reported increased scrutiny from Chinese regulators because of trade friction. Even American cherry growers are being affected, losing $89 million in sales last year.

    Meanwhile Huawei, a Chinese supplier of telecommunications equipment, has become the target of a US campaign to bar its gear from many global markets.
