Telecom digest: gumi neshanu nyanzvi zvekushandisa nezve IPv15, kuchengetedza ruzivo, zviyero uye mutemo muIT

Uku kusarudzwa kwezvinhu zvitsva kubva kuVAS Nyanzvi corporate blog. Pazasi pekucheka pane zvinyorwa nezve kurwisa botnets, iyo quantum Internet uye mabhiri matsva mumunda wekuchengetedza ruzivo.

Kuchengetedzwa kweruzivo muindasitiri yenhare

• Maitiro ekubata ne botnet zvikamu mune network yemupi
  DDoS kurwisa uchishandisa botnets imusoro kune network operators. Isu tinokurukura anonyanya kufarirwa kurwisa mavector: "yechinyakare" mafashama, smurf kurwisa uye ping mafashama. Tichakuudzawo kuti dzingadzivirirwe sei.

• Botnet "spams" kuburikidza nema routers: ndiani anobatwa?
  Gore rapfuura, nyanzvi dzekuchengetedza ruzivo dzakawana malware yakarwisa mazana mana ezviuru ma routers. Zvinangwa zvaive zvishandiso zvine BroadCom UPnP basa rakaitwa. Verenga chinyorwa nezve nzira dzehutachiona: zviteshi uye zvishandiso zvinoshandiswa nehutachiona.

• Nharembozha dzeAmerica dzichakwikwidza nefoni spam
  Veserura kuUnited States vari kuunza tekinoroji yekusimbisa vanyoreri - chiyero cheSHAKEN/STIR. Isu tinotsanangura misimboti yekushanda kweprotocol - chinyorwa chine block diagraph uye mienzaniso yekodhi kubva kuGitHub repository American telecom.

• DDOS uye 5G: gobvu "pombi" - mamwe matambudziko
  DDoS kurwiswa kutyisidzira kuIoT uye 5G. Nyaya yacho inotaura nezve nzira mbiri dzekuchengetedza ma network evapeji veInternet uye ma cellular opareta: yakazara traffic yekuchenesa nzvimbo uye sarudzo yebhajeti ine yakavakirwa-mukati yekuchengetedza masisitimu.

Network matekinoroji

• SDN ichaiswa munzvimbo: nei ichidikanwa?
  Temporospatial SDN igadziriro yekuendesa software-inotsanangurwa network mu orbit. Ichagadzirisa zvivakwa zvesathelaiti nemabharumu anogovera Internet kumakona ari kure epasi. Iyo sisitimu inoshanda sei uye ndeapi matambudziko anofanirwa kugadziriswa nevagadziri - verenga izvo.

• Tekinoroji inounza kutangwa kwequantum network padhuze
  Boka renyika dzese revafizikisi rakakwanisa kugadzira quantum inodzokorora inokwanisa (kusiyana nemaanalogues) ekushanda pakamuri tembiricha. Inogona kunge iri kiyi yekutumirwa kwepasi rose quantum network. Isu tinokuudza kuti chii chitsva uye kukurukura mamwe matekinoroji anoswededza kugadzirwa kwehuwandu hweInternet - madhaimondi ekufambisa ekufambisa qubits uye kukanganisa kugadzirisa algorithms.

• Mainjiniya "akamonyoroka" mwenje mune optical fiber: nei izvi zvichidikanwa?
  Mainjiniya vekuAustralia vakurudzira mwenje we encoding mufiber yemaziso vachishandisa spin yephoton. Mukutaura, tekinoroji ichawedzera network network neka zana. Izvi zvinogona kuitika mumakore maviri anotevera. Nyaya yacho inotaura nezvezvikamu zvegadziriro, zvinhu zvinoshandiswa (somuenzaniso, antimony telluride) uye nheyo dzekushanda.

• 500 Gbit/s irekodhi yekumhanyisa mune fiber optic network
  Vatsvakurudzi veGermany vakawana kukurumidza kwekufambisa data kwe500 Gbit / s kekutanga mumamiriro emunda. Kuti vaite izvi, vakagadzira algorithm yekugadzirwa kwechiratidzo chenyeredzi (Probabilistic Constellation Shaping, kana PCS). Nyaya yacho ichakuudza nezve misimboti yekushanda kweprobabilistic modulation uye analogue yayo - geometric modulation.

Maitiro

• IPv6 Kuita: FAQ kune Vanopa Internet
  Ngatitarisei mibvunzo inonyanya kufarirwa ine vafambisi venhare pavanenge vachichinjira kuIPv6: nezve matambudziko anogona kuitika nehardware nemidziyo yemutengi.

• Iyo chiyero chitsva chakavakirwa paPCIe 5.0 "ichabatanidza" iyo CPU neGPU - chii chinozivikanwa nezvazvo
  Gore rino, Compute Express Link iri kuburitswa, chiyero chinopa yakakwira dhata kumhanya pakati pezvikamu zveheterogeneous system (CPU, FPGA uye GPU). Chinyorwa chacho chine ruzivo rwekutsanangurwa, tekinoroji paramita uye zvikanganiso zveiyo standard, iyo inocherechedzwa neIT indasitiri nyanzvi. Ngatitaureiwo nezve analogues - iyo CCIX uye GenZ zviyero.

• USB4 yakaziviswa: chii chinozivikanwa nezve chiyero
  Midziyo yakavakirwa pa USB4 ichaonekwa chete panosvika 2021. Asi mamwe maitiro echiyero anotozivikanwa: 40 Gbit / s bandwidth, kugona kubhadharisa panguva imwe chete uye kuratidza mufananidzo. Tinokurukura zvingangoshata.

• IPv6 protocol - kubva padzidziso kusvika pakuita
  Isu tinofananidza ruzivo rweRussia uye rwekunze mukuita IPv6 muIoT network uye indasitiri. Isu tinokurukura nzira dzekutama uye ruzivo rwekushandisa iyi protocol nemasangano akasiyana.

Mitemo muIT

• Hondo yekusarerekera kwemumbure mukana wekudzoka
  Nyaya itsva inoenderera mberi yedu yakatevedzana yezvinyorwa nezve Net Neutrality. Tichataura nezve bhiri idzva - iyo "Save the Internet" Mutemo, iyo ichafanirwa "kudzosera kumashure" mitemo yekusarerekera kune 2015 nyika. Isu tinopa maonero ehurumende nevamiriri veindasitiri uye tinotaura nezve tarisiro yechirongwa ichi.

• Mamiriro ezvinhu: Japan inogona kudzikamisa kurodha pasi zvemukati kubva paInternet
  Vakuru veJapan vari kuronga kupasisa bhiri rinorambidza vashandisi kudhawunirodha mafaera ese ane kodzero dzekodzero kubva paInternet. Verenga chinyorwa pamusoro pemaitiro evabudisi vekuJapan, vanogadzira zvemukati, masayendisiti nemagweta.

• Kupa yemahara Wi-Fi zvinoenderana nemutemo
  Iri igwara rinoshanda rekuisa hotspots munzvimbo dzeveruzhinji. Tinokuudza zvaunofanira kuteerera kuitira kuti usatyora mutemo. Iwe zvakare uchawana kurudziro yekusarudza michina pano.

Mamwe madhiri pa blog yedu:

• Chiitiko chako pachako: VAS Nyanzvi webinars nezve SKAT, CG-NAT uye DPI
• Network digest: 17 nyanzvi zvinhu nezve Wi-Fi uye 5G
• 20 nyanzvi zvinhu pamaprotocol, zviyero uye kuchengetedza ruzivo
