Telecom digest: 15 akatswiri zida za IPv6, chitetezo chidziwitso, miyezo ndi malamulo mu IT

Izi ndi zosankha zatsopano kuchokera ku VAS Experts corporate blog. Pansi pa odulidwawo pali nkhani zolimbana ndi ma botnets, kuchuluka kwa intaneti ndi mabilu atsopano pankhani yachitetezo chazidziwitso.

Chitetezo cha chidziwitso mumakampani a telecom

• Momwe mungathanirane ndi zigawo za botnet mu network ya operekera
  Kuukira kwa DDoS pogwiritsa ntchito ma botnet ndi mutu kwa ogwiritsa ntchito maukonde. Timakambirana za ma vectors otchuka kwambiri: kusefukira kwa "classic", kuukira kwa smurf ndi kusefukira kwa ping. Tidzakuuzaninso momwe angapewere.

• Botnet "spams" kudzera ma routers: ndani akukhudzidwa?
  Chaka chatha, akatswiri achitetezo azidziwitso adapeza pulogalamu yaumbanda yomwe idaukira ma routers 400. Zolingazo zinali zida zomwe BroadCom UPnP ntchito idatsegulidwa. Werengani nkhani yokhudzana ndi njira zotengera matenda: madoko ndi zida zomwe ma virus amagwiritsa ntchito.

• Matelefoni aku America adzalimbana ndi spam yamafoni
  Ogwiritsa ntchito mafoni ku United States akuyambitsa umisiri wotsimikizira anthu olembetsa - mulingo wa SHAKEN/STIR. Timalongosola mfundo zogwirira ntchito za protocol - nkhaniyi ili ndi chithunzi cha block ndi zitsanzo za code kuchokera ku GitHub repository American telecom.

• DDOS ndi 5G: "chitoliro" chochuluka chimatanthauza mavuto ambiri
  Kuwukira kwa DDoS ndikuwopseza IoT ndi 5G. Nkhaniyi ikukamba za njira ziwiri zotetezera maukonde a opereka intaneti ndi ogwiritsira ntchito ma cellular: malo oyeretsera magalimoto komanso njira ya bajeti yokhala ndi machitidwe otetezera omangidwa.

Matekinoloje amtaneti

• SDN idzayambitsidwa mumlengalenga: chifukwa chiyani kuli kofunikira?
  Temporospatial SDN ndi njira yotumizira maukonde ofotokozedwa ndi mapulogalamu mu orbit. Idzayang'anira zomangamanga za satellite ndi ma baluni omwe amagawa intaneti kumakona akutali a dziko lapansi. Momwe dongosololi limagwirira ntchito komanso zovuta zomwe opanga akuyenera kuthana nazo - werengani nkhaniyi.

• Tekinoloje yomwe idzabweretse kukhazikitsidwa kwa ma network a quantum pafupi
  Gulu lapadziko lonse la akatswiri a sayansi ya zakuthambo lakwanitsa kupanga quantum repeater yomwe imatha (mosiyana ndi ma analogue) yogwira ntchito kutentha. Ikhoza kukhala chinsinsi cha kutumizidwa kwa ma network a quantum padziko lonse lapansi. Tikukuuzani zomwe zakhala zikuchitika ndikukambirana zaukadaulo wina womwe umayandikitsa kupangidwa kwa intaneti ya quantum - diamondi zopangira zotumizira ma qubits ndi ma algorithms owongolera zolakwika.

• Mainjiniya "opotoza" kuwala mu fiber fiber: chifukwa chiyani izi ndizofunikira?
  Mainjiniya aku Australia apereka zowunikira zowunikira mu fiber optical pogwiritsa ntchito kupindika kwa Photon. Mwachidziwitso, teknoloji idzawonjezera mphamvu ya intaneti ndi zana. Izi zikhoza kuchitika zaka ziwiri zikubwerazi. Nkhaniyi ikukamba za zigawo za dongosolo, zipangizo zomwe zimagwiritsidwa ntchito (mwachitsanzo, antimony telluride) ndi mfundo zogwirira ntchito.

• 500 Gbit/s ndi mbiri yothamanga mu ma fiber optic network
  Ofufuza aku Germany apeza liwiro losamutsa deta la 500 Gbit / s kwa nthawi yoyamba m'malo akumunda. Kuti achite izi, adapanga algorithm yopangira kuthekera kwa gulu la nyenyezi (Probabilistic Constellation Shaping, kapena PCS). Nkhaniyi idzakuuzani za mfundo za ntchito ya probabilistic kusinthasintha ndi analogi ake - kusinthasintha geometric.

Miyezo

• IPv6 Kukhazikitsa: FAQ kwa Opereka intaneti
  Tiyeni tiwone mafunso odziwika kwambiri omwe opanga ma telecom amakhala nawo akasinthira ku IPv6: zamavuto omwe angakhalepo pa hardware ndi zida zamakasitomala.

• Muyezo watsopano wozikidwa pa PCIe 5.0 "ulumikiza" CPU ndi GPU - zomwe zimadziwika nazo
  Chaka chino, Compute Express Link ikumasulidwa, muyezo womwe udzapereke kuthamanga kwa data pakati pa zigawo za heterogeneous systems (CPU, FPGA ndi GPU). Nkhaniyi ili ndi tsatanetsatane wa mafotokozedwe, magawo aukadaulo ndi zofooka za muyezo, zomwe zimawonedwa ndi akatswiri amakampani a IT. Tiyeni tikambiranenso za analogue - miyezo ya CCIX ndi GenZ.

• USB4 yalengeza: zomwe zimadziwika za muyezo
  Zipangizo zozikidwa pa USB4 ziziwoneka pofika 2021. Koma makhalidwe ena a muyezo amadziwika kale: 40 Gbps bandiwifi, luso pa nthawi yomweyo kulipira ndi kusonyeza fano. Timakambirana zomwe zingasokoneze.

• IPv6 protocol - kuchokera kumalingaliro kupita kukuchita
  Timafanizira zochitika zaku Russia ndi zakunja pakukhazikitsa IPv6 mumanetiweki a IoT ndi mafakitale. Timakambirana za njira zosamukira kudziko lina komanso zochitika zogwiritsira ntchito ndondomekoyi ndi mabungwe osiyanasiyana.

Malamulo mu IT

• Nkhondo Yopanda Ndandanda ya Net Ndi Mwayi Wobwereranso
  Nkhani yatsopano yomwe ikupitirira mndandanda wathu wa posts za Net Neutrality. Tikambirana za bilu yatsopano - lamulo la "Save the Internet", lomwe liyenera "kubweza" malamulo osalowerera ndale ku boma la 2015. Timapereka malingaliro a oimira boma ndi mafakitale ndikulankhula za chiyembekezo cha ntchitoyi.

• Mkhalidwe: Japan ikhoza kuchepetsa kutsitsa zomwe zili pa intaneti
  Akuluakulu a boma ku Japan akuganiza zokhazikitsa lamulo loletsa anthu kutsitsa mafayilo onse otetezedwa pa intaneti. Werengani nkhani yokhudza zomwe osindikiza ku Japan, opanga zinthu, asayansi ndi maloya anachita.

• Kupereka Wi-Fi yaulere motsatira malamulo
  Ichi ndi chiwongolero chothandiza poyika malo opezeka anthu ambiri. Tikukuuzani zomwe muyenera kutchera khutu kuti musaphwanye lamulo. Mupezanso malingaliro osankha zida apa.

Zolemba zina pa blog yathu:

• Zochitika pawekha: VAS Akatswiri pa webinars za SKAT, CG-NAT ndi DPI
• Network digest: zida 17 zaukadaulo za Wi-Fi ndi 5G
• Zida 20 za akatswiri pama protocol, miyezo ndi chitetezo chazidziwitso
