Chii chinonzi Ring network redundancy?

Network mhete inoshandisa mhete inoenderera kubatanidza mudziyo wega wega.Inova nechokwadi chekuti chiratidzo chinotumirwa nemudziyo mumwe chinogona kuonekwa nemimwe michina yese paringi.Iyo ring network redundancy inoreva kana switch inotsigira network kana tambo yekubatanidza yakanganiswa.Iyo switch inogashira ruzivo urwu uye inomisa chiteshi chayo chekuchengetedza kudzoreredza kushanda kwakajairwa kwekutaurirana kwetiweki.Panguva imwecheteyo, shanduko ine zviteshi 7 uye 8 yakabviswa mune network, relay yakavharwa, uye chiratidzo chemwenje chinotumira alarm yenhema kumushandisi.Mushure mekunge tambo yagadziridzwa kune yakajairwa, basa reiyo relay uye chiratidzo mwenje kudzoka kune yakajairika mamiriro.

Muchidimbu, iyo Ethernet ring redundancy tekinoroji inogona kugonesa imwe intact yekutaurirana chinongedzo kana chinongedzo chekutaurirana chakundikana, izvo zvinovandudza zvakanyanya kuvimbika kwekutaurirana kwetiweki.

Chii chinonzi IP protocol?

Iyo IP protocol iprotocol yakagadzirirwa kuti makomputa network itaurirane.MuInternet, iri seti yemitemo inoita kuti ese macomputer network akabatana neInternet ataurirane, uye inotsanangura mitemo iyo makomputa anofanirwa kutevedzera paanenge achitaurirana paInternet.Makomputa masisitimu anogadzirwa nechero mugadziri anogona kubatana neInternet chero achitevedzera IP protocol.Iwo network masisitimu uye zvishandiso zvinogadzirwa nevagadziri vakasiyana, senge Ethernet, packet-switching network, nezvimwewo, haigone kutaurirana.Mamiriro acho akasiyana.Iyo IP protocol ndeyechokwadi seti yeprotocol software inoumbwa nesoftware zvirongwa.Inoshandura zvakafanana "mafuremu" akasiyana kuita "IP datagram" fomati.Kutendeuka uku ndechimwe chezvinhu zvakakosha zveInternet, zvichiita kuti marudzi ese emakombuta awane kuwirirana paInternet, ane hunhu hwe "kuvhurika".Izvo chaizvo nekuda kweIP protocol iyo iyo Internet yakakurumidza kuvandudzwa kuita yakakura pasi rose, yakavhurika komputa yekukurukurirana network.Naizvozvo, iyo IP protocol inogona zvakare kunzi "Internet Protocol".

IP kero

Panewo zvakakosha zvikuru zvirimo muIP protocol, kureva kuti, kero yakasiyana-siyana inotsanangurwa kune imwe neimwe kombiyuta nemimwe michina paInternet, inonzi "IP address".Nekuda kwekero iyi yakasiyana nedzimwe, zvinova nechokwadi chokuti kana mushandisi akashanda pakombiyuta inetiweki, anogona kusarudza zvakanaka uye zviri nyore chinhu chaanoda kubva muzviuru zvemakombiyuta.

IP address dzakafanana nedzedu dzepamba, kana uchinyorera munhu tsamba, unofanira kuziva kero yake kuti mupositi atumire tsamba.Kombiyuta inotumira meseji senge positi, inofanira kuziva “kero yepamba” yakasiyana nedzimwe kuitira kuti isaendesa tsamba kumunhu asiri iye.Ndizvo chete kuti kero yedu inoratidzwa mumashoko, uye kero yekombuta inoratidzwa mumabhinari manhamba.

IP address inoshandiswa kupa nhamba kukombiyuta paInternet.Zvinoonekwa nemunhu wese zuva rega rega ndezvekuti PC yese inetiweki inoda IP kero kuti itaure zvakajairwa.Tinogona kuenzanisa "kombiyuta yega" ne "foni", ipapo "IP address" yakaenzana ne "nhamba yefoni", uye router muInternet yakaenzana ne "program-controlled control" muhofisi yekufonera.
