5G? IoT? Fiber Deep? 600G? We Are ready for networking at 2019!
For years we have all been talking about the emergence of 5G services, the Internet of Things (IoT) and the new high-capacity, low-latency network architectures that will be needed to support the resulting onslaught of bandwidth. Higher-speed data rates are critical to electronic evolution and revolution.
Here are some of my collection of newest trends and predictions for year 2018. have picked and mixed here quotations from many articles (linked to source) with some of my own additions to make this posting.
5G: The most newsworthy stories in wireless today are all about 5G. In 2019, we enter a cautious, early-adoption phase of this next generation of wireless technology. 2019 will be the year when we see the first commercial networks turning on and first handsets arriving in the market. Only a small number of users will get a first taste of 5G in specific geographic locations, using specific applications, none of which are ubiquitous or cost-optimized. For more details read my 5G trends for 2019 posting.
Deep fiber: Deep deployment of fiber optics into national network infrastructure might not be as glamorous as the eagerly anticipated launch of fifth-generation mobile networks (5G); however, it is just as important—maybe even more important. Wired broadband access supports as much as 90 percent of all internet traffic even though the majority of traffic ultimately terminates on a wireless device. Wireline and wireless networks are driving new architectures to support the move from 4G LTE to 5G infrastructure. In fact, 5G relies heavily on fiber infrastructure. Service providers in the access market are talking about the evolution of their plants to a Fiber Deep (FD) Architecture. FD architectures move the optical node (the optical-to-electrical conversion point) deeper into the network and closer to the subscriber. This means shorter copper, faster speed, more capacity and reduction in maintenance cost for both cable TV network and telephone line based access networks.
Ethernet: Faster Ethernet speeds are taken to use. These transitions are driven by the increasing global IP traffic. Hyper-scalers and service providers are moving from 100GbE to 400GbE Ethernet rates and beyond. In this speed development 56Gb/s And 112Gb/s SerDes Matter.
TSN: Time-Sensitive Networking (TSN) is a set of standards under development by the Time-Sensitive Networking task group of the IEEE 802.1 working group. TSN standards documents that are specified by IEEE 802.1 can be grouped into three basic key component categories that are time synchronization; scheduling and traffic shaping; selection of communication paths, path reservations and fault-tolerance. Industrial Ethernet networks embrace time-sensitive networking (TSN) technology to integrate operational technology (OT) and information technology (IT).
SDN: Software-defined networking (SDN) technology is an approach to cloud computing that facilitates network management and enables programmatically efficient network configuration in order to improve network performance and monitoring. SD-WAN applies similar technology to a wide area network (WAN). SD-WAN allows companies to build higher-performance WANs using lower-cost and commercially available Internet access, enabling businesses to partially or wholly replace more expensive private WAN connection technologies such as MPLS.
IPv6: IPv4 and IPv6 are the two Protocols Run the Internet in 2019. The long-forecasted day the internet runs out of addresses has arrived and it marks a paradigm shift in the internet’s evolution. Though IPv6 has been available globally since 2012, it has seen a slow, if increasing, adoption rate. The migration to IPv6 is inevitable but will take time during that both systems are in use. In many networks a notable amount of traffic is already IPv6.
New Internet protocols: Internet security gets a boost with TLS 1.3. Also HTTP is in process of switching to a protocol layered on top of UDP. Today’s HTTP (versions 1.0, 1.1, and 2) are all layered on top of TCP (Transmission Control Protocol) that is not very optimal in today’s applications as SSL over TCP requires subsequent round trips to establish the encrypted connection.
IoT: The IoT world is here, and the level and rate of convergence is increasing in volume and velocity. We will see the evolution of converged networks for IoT applications in mind. Network convergence (version 2.0) is here with changes and improvements made since the first converged network (Convergence 1.0). TIA TR-42 (Telecommunications Cabling Systems ANSI/TIA-568 family), BICSI (TDMM and others) and proprietary or third documents must adapt and adjust.
PoE: The IEEE 802.3bt standard, approved by the IEEE Standards Association Board on September 27, 2018, included some significant enhancements especially for LED lighting systems. This specification allows for up to 90W of delivered power for cable lengths of up to 100m through the use of all four pairs of wires.
Trade wars: It seem that there is a high tech “trade war” between USA and China. It affects specifically networking business. Big Chinese manufacturers Huawei and ZTE are have received sanctions and their products are not wanted by many countries citing their business practices and potential security nightmares. For example Japan to halt buying Huawei, ZTE equipment and Huawei has been under fire in UK, just to mention examples. It seems that the business that is lost by Huawei and ZTE could benefit Ericsson and Nokia in the 5G base station markets for short term.
Security: The internet is going to hell and its creators want your help fixing it. All agree on one thing however: Right now there is a serious battle for heart and minds, the future of the internet and global society itself. There seems to be need for a conference to address the fact that people increasingly see tech as a threat and no longer as a pure force for good. Government set to revise internal rules on procurement to protect national cybersecurity. Your DNS might be broken, and you don’t even know it. Some DNS old hacks gets thrown out of use by February 1st, 2019.
WiFi: WiFi technology gets new marketing naming. The numerical sequence includes: Wi-Fi 6 to identify devices that support 802.11ax technology, Wi-Fi 5 to identify devices that support 802.11ac technology, Wi-Fi 4 to identify devices that support 802.11n technology.
Faster mobile: Mobile networks are getting faster in many countries. Mobile networks are killing Wi-Fi for speed around the world. Average data speeds on mobile networks now outpace customer’s Wi-Fi connection, on average, in 33 countries. That’s the The State of Wifi vs Mobile Network Experience as 5G Arrives.
Energy efficiency: We need to develop more energy efficient networking technologies. Today, information and communication technologies globally consume 8% of electricity and doubles every year.

Valokuituun investoidaan nyt satoja miljoonia euroja vuodessa. Valokuitusen toimitusjohtaja Heikki Kaunisto arvioi tänään jopa, että markkinat ovat kuumentumassa. Lisävauhtia haetaan kumoamalla kuituun liittyviä myyttejä ja esittelemällä niiden etuja muihin laajakaistatekniikoihin verrattuna.
Valokuitunen selvitytti lokakuussa 2022 teetetyssä tutkimuksessa suomalaisten ajatuksia eri verkkoyhteyksistä, ympäristöasioista ja netinkäytöstä. Tutkimuksen mukaan suomalaiset arvostavat kodin hyvää internetyhteyttä. Sitä mieltä on lähes kaikki tutkimukseen vastanneet (97 %) ja erittäin tärkeänä sitä pitää 71 prosenttia suomalaisista. Eri yhteyksien paremmuutta arvioitaessa noin kaksi viidestä (37 prosenttia) arvioi valokuidun olevan paras internet-ratkaisu.

Starlink -satelliittinetti saapui Suomeen – Hinta ja nopeus selville
https://fin.afterdawn.com/uutiset/2022/11/26/starlink-suomi-hinta-nopeus
Elon Muskin omistaman Starlinkin satelliittinetti on vihdoin saatavilla myös Suomessa.
Starlink on avannut tällä viikolla palvelun maapallon pohjoisemmissa kolkissa: tämän viikon aikana Starlinkin satelliittiyhteyden tarjonta laajeni Suomen lisäksi myös Ruotsiin, Norjaan, Kanadaan sekä Yhdysvalloissa Alaskan osavaltioon.
Aivan ilmainen Starlink ei ole Suomeenkaan tilattuna. Satelliittinetin vastaanottoon tarvittava laitteisto maksaa joko 565 euroa tai 2920 euroa. Näistä kalliimpi vaihtoehto on “high performance” -välineistö, joka eroaa peruslaitteistosta sillä, että se toimii paremmin lumen keskellä, sulattaen satelliittivastaanottimen päältä tehokkaammin lunta – lisäksi kalliimpi malli toimii paremmin myös erittäin kuumissa lämpötiloissa.

Microsoft acquires startup developing high-speed cables for transmitting data
https://techcrunch.com/2022/12/09/microsoft-acquires-startup-developing-high-speed-cables-for-transmitting-data/
Microsoft today announced that it acquired Lumenisity, a U.K.-based startup developing “hollow core fiber (HCF)” technologies primarily for data centers and ISPs. Microsoft says that the purchase, the terms of which weren’t disclosed, will “expand [its] ability to further optimize its global cloud infrastructure” and “serve Microsoft’s cloud platform and services customers with strict latency and security requirements.”
HCF cables have been around since the ’90s. But what Lumenisity brings to the table is a proprietary design with an air-filled center channel surrounded by a ring of glass tubes. The idea is that light can travel faster through air than glass; in a trial with Comcast in April, a single strand of Lumenisity HCF was reportedly able to deliver traffic rates ranging from 10 Gbps to 400 Gbps.

Laaja tutkimus: nettinopeudet jäävät kauaksi luvatusta
https://etn.fi/index.php/13-news/14409-laaja-tutkimus-nettinopeudet-jaeaevaet-kauaksi-luvatusta
Toimiiko nettisi sillä nopeudella, mistä maksat? Useimmiten näin ei ole, ainakaan laajan amerikkalaistutkimuksen perusteella, josta tietoturvayhtiö AtlasVPN raportoi. Pahimmillaan mitatut nopeudet jäävät alle kolmasosaan luvatuista.
Internet-palveluntarjoajat mainostavat usein Internet-nopeuksia, jotka ovat huomattavasti suurempia kuin kuluttajien todelliset kokemat nopeudet. Tämä ristiriita voi olla turhauttavaa ja hämmentävää käyttäjille, jotka odottavat saavansa Internet-palveluntarjoajansa lupaamaa nopeutta.
Atlas VPN -tiimin analysoimien tietojen mukaan nettinopeus voi jäädä jopa alle kolmannekseen luvatusta. Mittaukset osoittavat, että nopeammat Internet-paketit ovat yleensä kaukana todellisista nopeuksista, kun taas hitaammat liittyvät ovat lähempänä todellisia nopeuksia.

Cloudflare servers don’t own IPs anymore – so how do they connect to the Internet?
https://blog.cloudflare.com/cloudflare-servers-dont-own-ips-anymore/
A lot of Cloudflare’s technology is well documented. For example, how we handle traffic between the eyeballs (clients) and our servers has been discussed many times on this blog: “A brief primer on anycast (2011)”, “Load Balancing without Load Balancers (2013)”, “Path MTU discovery in practice (2015)”, “Cloudflare’s edge load balancer (2020)”, “How we fixed the BSD socket API (2022)”.
However, we have rarely talked about the second part of our networking setup — how our servers fetch the content from the Internet. In this blog we’re going to cover this gap. We’ll discuss how we manage Cloudflare IP addresses used to retrieve the data from the Internet, how our egress network design has evolved and how we optimized it for best use of available IP space.

KEY POINTS
Nokia is planning to launch 4G internet on the moon later this year, an executive for the company said.
It will be used within Nasa’s Artemis 1 mission, which aims to establish a human presence on the moon.
The aim is to show that terrestrial networks can meet the communications needs of future space missions.
The Finnish telecommunications group plans to launch the network on a SpaceX rocket over the coming months, Luis Maestro Ruiz De Temino, Nokia’s principal engineer, told reporters earlier this month at the Mobile World Congress trade show in Barcelona.
The network will be powered by an antenna-equipped base station stored in a Nova-C lunar lander designed by U.S. space firm Intuitive Machines, as well as by an accompanying solar-powered rover.
An LTE connection will be established between the lander and the rover.
The infrastructure will land on the Shackleton crater, which lies along the southern limb of the moon.
Nokia says the technology is designed to withstand the extreme conditions of space.
The network will be used within Nasa’s Artemis 1 mission, which aims to send the first human astronauts to walk on the moon’s surface since 1972.

Millaisen viiveen reaaliaikainen netti vaatii?
https://etn.fi/index.php/13-news/15055-millaisen-viiveen-reaaliaikainen-netti-vaatii
Saksalainen DE-CIX käynnisti toukokuun lopulla viikolla Suomen kolmannen internetin yhdyspisteen. Sen myötä käyttäjille tulevat entistä nopeammat yhteydet. Toimitusjohtaja Ivo Ivanov maalaili jo tulevaisuutta, jossa virtuaalinen maailma toimii yhtä nopeasti kuin reaalinen. Tälle verkolle asettuvat melkoiset vaatimukset erityisesti latenssin suhteen.
DE-CIX käynnisti toukokuun lopussa Suomen kolmannen Internet-yhdyspisteen Nokian reitittimillä. Parantuneiden yhteyksien myötä Suomi on taas lähempänä muita Pohjoismaita ja Eurooppaa. Mutta mitä se tarkoittaa reaaliaikaisen, tai immersiivisen internetin kannalta?
Maailmalla on tutkittu paljonkin sitä, millaisen viiveen ihmisaivot kokevat luonnolliseksi tai miellyttäväksi eri tilanteissa. Kosketuksen aistimuksessa viive voi olla 20 millisekuntia, näköärsykkeen havaitsemissa alle 13 millisekuntia ja äänen kuulemisessa alle puoli millisekuntia. Tämä tarkoittaa, että ollakseen oikeasti immersiivisen, sallitaan esimerkiksi AR/VR-kokemukselle millisekuntitason viive.
Valon nopeus on 300 tuhatta kilometriä sekunnissa, mutta Ivanov muistutti, että yhdessä millisekunnissa signaali kulkee optimaalisissa olosuhteissa maksimissaan 80 kilometrin päähän. Tämä on siis ns. RTT-aika eli aika, joka datapaketilta kuluu matkata laitteesta kohteeseen ja takaisin. Käytännössä tämä tarkoittaa, että datan pitää olla paljon lähempänä, jotta kokemus olisi miellyttävä.
DE-CIX:n uuden Equinixin datakeskuksessa sijaitsevan yhdyspisteen ansiosta Suomen ja Frankfurtin välinen ”matka” kutistuu alle 25 millisekuntiin
DE-CIX nojaa laitteisiin esimerkiksi Nokian 7750 SR1-reitittimiin, joiden moottorina on FP5-fotoniikkaprosessori. Se on markkinoiden ensimmäinen 800G-tasoiset runkoyhteydet mahdollistava prosessori.

SpaceX’s Starlink satellite internet constellation continues to deliver stunning download speeds in Germany. The network, comprised of thousands of satellites, became well known all over for its remarkable download speeds soon after it was opened for public participation. However, the hype around Starlink, the world’s first commercially successful low Earth orbit (LEO) satellite internet, led to millions of users signing up for SpaceX’s service – faster than SpaceX could add capacity. This led to performance downgrades across areas of high demand, particularly in several regions of America. However, now and then, Starlink reminds everyone of its true potential, and that’s the case with today’s internet tests.

Lasers enable internet backbone via satellite, may soon eliminate need for deep-sea cables
https://techxplore.com/news/2023-06-lasers-enable-internet-backbone-satellite.html
Optical data communications lasers can transmit several tens of terabits per second, despite a huge amount of disruptive air turbulence. ETH Zurich scientists and their European partners demonstrated this capacity with lasers between the mountain peak, Jungfraujoch, and the city of Bern in Switzerland. This will soon eliminate the necessity of expensive deep-sea cables.
