In the Nyaya yapfuura Ndakatanga sumo pfupi yekuti BitTorrent protocol inoshanda sei inova nzira yangu yandinofarira yekugovera mafaera paP2P network. Isu takanga tabvumirana kuti maitiro acho anosanganisira kugadzira torrent faira uye kuigovana kuburikidza ne tracker (Server iyo ine basa rekutaurirana kune yakasara network kuwanikwa uye nzvimbo yefaira uye nekuiwana). Imwe nzira ndeye kushandisa magineti link, yaunotsvaga nayo node nenode kusvika wawana faira. Aya ndiwo mafambiro anoenderera mberi.
Zvinofanira kuva pachena kuti crawler yakaita seyero peji. Inongori neruzivo rwekuti ungawane kupi chimwe chinhu, asi haitore chikamu zvakananga mukutsinhana.
Kana imwe nhengo yeswarm (Iyo seti yemakomputa akabatana kune network) ane chido mufaira anotanga nekudhawunirodha zvimedu zvayo (Ndichataura zvakadzama pamusoro pazvo gare gare.) Pakusvika pane imwe nhanho yekubuda tanga kugovera iwo mafaera nevamwe vatengi vanofarira faira rimwe chete. Mune mamwe mazwi, munhu wese anorodha iyo faira inopa bandwidth kuitira kuti vamwe vagone kuidhawunirodha, vachiwedzera kumhanya kune vese.
Dhawunirodha mafaera pamusoro peBitTorrent protocol. Mabasa.
Ikozvino ini ndoda kutsanangura zvakadzama zvikamu zvakasiyana zveBitTorrent network nebasa ravo.
The tracker
A BitTorrent tracker Iyo sevha yakaisa software inotungamira yepakati kuronga kufambiswa kwemafaira pakati pevashandisi. Iyo sevha yambotaurwa haitore makopi emafaira sezvo basa rayo riri rekuita kuti vaviri vacho vasangane.
Kuchinjana ruzivo, tracker uye mutengi vachishandisa iri nyore protocol pamusoro peHTTP yakafanana neyemushandisi anopinda peji rewebhu. Mukutsinhana uku, vatengi vanozivisa tracker nezve faira yavanoda kurodha, IP yayo uye chiteshi, uye tracker inopindura nerunyorwa rwevezera vanotora iyo yakafanana faira uye yavo yekuonana ruzivo. Avo vanogadzira rondedzero padivi peiyo yaunoda kuwedzera pakurodha vanogadzira yambotaurwa "swarm". Nekudaro, nhanho iyi inogona kudzivirirwa sezvo vatengi veBitTorrent vakaisa Distributed Hash Tafura (DHT) tekinoroji umo node yega yega inotora basa retracker.
Iyo torrent file
Iyo inonziwo metainfo, ine extension .torrent uye ndiyo inotorwa kubva kune mawebsite akawanda anounganidza torrents.
Iri faira rine ruzivo rwakavharirwa kusanganisira URL yevanokambaira, zita refaira, uye ma hashi ezvikamu zvefaira kuti zvionekwe kuti ndezvipi zvakadhaunirodwa.. Kugadzira iyi faira mutengi weBitTorrent anoda nzvimbo yefaira rekutanga uye url yeanokambaira.
Seeders
Kubva panguva iyo faira raiswa kekutanga, timu inozivikanwa semuridzi kana mbeu uye inofanirwa kuramba yakabatana nepush kusvika mamwe ese asara aine kopi yefaira kuti vamwe vaenderere mberi nekuridhawunirodha. Zita remadunhurirwa remudzvari rinoshandiswawo kune vatengi avo, vakadhawunirodha faira, vachiri kubatana zvizere kuti vabvumire vamwe kuti variwane. Izvo zvinofanirwa kutaurwa kuti iyo protocol inobhadhara avo vanogovana nekupa iyo yekutanga mukurodha.
Leechers (leeches)
Hazvidikanwi kuti nhengo yechikwata kana vezera ive nefaira yose yekugovera. Vezera vasina kopi yakakwana yefaira vanonzi maleecher kana leeches. Maleecher anobvunza tracker runyoro rwedzimwe nhengo dzechamhere dzine zvikamu zvisipo zvefaira. Iyo leecher inozoenderera mberi kurodha chikamu chinodiwa cheimwe yeaya mapairi. Panguva imwecheteyo, leecher ichaenderera mberi nekugovera zvikamu izvo zvakadhaunirodwa zvakatopera.
Muchinyorwa chinotevera tichataura pamusoro pemitemo inodzora kushanda pakati pemapato.
Ini handina kumbobvira ndafarira iyi protocol kunze kwekurodha iso. Kugovera uye kumanikidza kugovera (ndizvo zvazviri) zviri nani ed2k / Kad. Nokuti p2p iri mumaawa akaderera, asi KAD ine simba risati razivikanwa kana kuti risina kuda kushandisa; yakanyatso kuderedzwa uye pasina kudiwa kwemaseva (ed2k) uye trackers (Bittorrent) kugovera zvirimo.
Thanks.
