Ukhuseleko lolwazi kwishishini le-telecom

• Indlela yokujongana namacandelo e-botnet kwinethiwekhi yomnikezeli
  Ukuhlaselwa kwe-DDoS usebenzisa i-botnets yintloko kubaqhubi benethiwekhi. Sixoxa ngezona zithwala zidumileyo zohlaselo: “zakudala” izandyondyo, uhlaselo lwe-smurf kunye nezikhukhula ze-ping. Siza kukuxelela nokuba zinokuthintelwa njani.

• I-Botnet "spams" ngokusebenzisa imizila: ngubani ochaphazelekayo?
  Kunyaka ophelileyo, iingcali zokhuseleko lolwazi zifumene i-malware ehlasele ii-routers ezingamawaka angama-400. Iithagethi ibizizixhobo ezinomsebenzi we-BroadCom UPnP osebenzayo. Funda inqaku malunga neendlela zosulelo: amazibuko kunye nezixhobo ezisetyenziswa yintsholongwane.

• Iifowuni zaseMelika ziya kulwa ne-spam yefowuni
  Abasebenzisi beeSelula e-United States bazisa ubuchwephesha boqinisekiso lwababhalisi - umgangatho we-SHAKEN/STIR. Sichaza imigaqo yokusebenza kweprotocol - inqaku liqulethe umzobo webhloko kunye nemizekelo yekhowudi ukusuka kwindawo yokugcina yeGitHub I-telecom yaseMelika.

• I-DDOS kunye ne-5G: "umbhobho" ogqithiseleyo uthetha iingxaki ezininzi
  Ukuhlaselwa kwe-DDoS kuyingozi kwi-IoT kunye ne-5G. Izinto eziphathekayo zithetha ngeendlela ezimbini zokukhusela amanethiwekhi ababoneleli be-intanethi kunye nabaqhubi beeselula: amaziko okucoca izithuthi ezibanzi kunye nokhetho lwebhajethi kunye neenkqubo zokhuseleko ezakhelwe ngaphakathi.

Iitekhnoloji zenethiwekhi

• I-SDN iya kuqaliswa kwisithuba: kutheni kuyimfuneko?
  I-Temporospatial SDN yinkqubo yokubeka i-software-defined networks in orbit. Iza kulawula iziseko ezingundoqo zesathelayithi kunye neebhaluni ezisasaza i-Intanethi kwiikona ezikude zesijikelezi-langa. Indlela esebenza ngayo inkqubo kwaye yintoni ubunzima abaphuhlisi abasafuna ukuyicombulula - funda imathiriyeli.

• Itekhnoloji eya kusondeza ukuqaliswa kweenethiwekhi ze-quantum
  Iqela lamazwe ngamazwe leengcali zefiziksi likwazile ukuphuhlisa i-quantum repeater ekwaziyo (ngokungafaniyo ne-analogues) yokusebenza kwiqondo lokushisa. Inokuba sisitshixo sokusasazwa kothungelwano lwe-quantum yehlabathi. Siyakuxelela ukuba yintoni na into entsha kwaye sixoxe ngezinye itekhnoloji ezisondeza ukudalwa kwe-Intanethi ye-quantum - iidayimani ezenziweyo zokuhambisa i-qubits kunye ne-algorithms yokulungisa iimpazamo.

• Iinjineli "zijije" ukukhanya kwifiber optical: kutheni le nto iyimfuneko?
  Iinjineli zaseOstreliya zicebise ukukhanya kwekhowudi kwifiber ebonakalayo kusetyenziswa i-spin yefoton. Kwithiyori, itekhnoloji iya kwandisa umthamo wenethiwekhi ngamaxesha alikhulu. Oku kunokwenzeka kwiminyaka emibini ezayo. Inqaku lithetha ngamacandelo enkqubo, izinto ezisetyenzisiweyo (umzekelo, i-antimony telluride) kunye nemigaqo yokusebenza.

• I-500 Gbit / s yirekhodi yesantya kwiinethiwekhi ze-fiber optic
  Abaphandi baseJamani baye bafezekisa isantya sokudlulisa idatha ye-500 Gbit / s okokuqala ngqa kwiimeko zentsimi. Ukwenza oku, baye baphuhlisa i-algorithm yokwakheka okunokwenzeka kwekroza leenkwenkwezi (Probabilistic Constellation Shaping, okanye PCS). Izinto eziphathekayo ziya kukuxelela malunga nemigaqo yokusebenza yemodulation probabilistic kunye ne-analogue yayo - ukuguqulwa kwejometri.

MiGangatho

• IPv6 Ukuphunyezwa: FAQ kuBaboneleli be-Intanethi
  Makhe sijonge eyona mibuzo idumileyo abanayo abaqhubi be-telecom xa betshintshela kwi-IPv6: malunga neengxaki ezinokubakho ngehardware kunye nezixhobo zabaxumi.

• Umgangatho omtsha osekelwe kwi-PCIe 5.0 "uya kudibanisa" i-CPU kunye ne-GPU - yintoni eyaziwayo ngayo
  Kulo nyaka, i-Compute Express Link ikhutshwa, umgangatho oza kubonelela ngesantya esiphezulu sokudlulisa idatha phakathi kwamacandelo eenkqubo ezihlukeneyo (CPU, FPGA kunye ne-GPU). Eli nqaku liqulethe iinkcukacha zenkcazo, iiparitha zobugcisa kunye neentsilelo zomgangatho, eziphawulwa ziingcali zoshishino lwe-IT.
