Ichi chinyorwa chakazvarwa nekuda kwechinyorwa . Ini handibvumirane neakawanda ezvinyorwa zvemunyori, uye mune ino chinyorwa ini handidi kungovapikisa chete, asi zvakare kuisa mberi kwangu dzidziso, dzandichazodzivirira mune zvakataurwa. Tevere, ini ndichataura nezve akati wandei misimboti yandinotevedzera pakugadzira network yemuno kune chero bhizinesi.
Nheyo yekutanga kuvimbika. Iyo isina kuvimbika network ichagara ichidhura zvakanyanya nekuda kwemutengo wekuchengetedza kwayo, kurasikirwa kwenguva yekurasikirwa uye kurasikirwa kubva kunze kwekupindira. Zvichienderana nemusimboti uyu, ini ndinogara ndichigadzira iyo huru network ine wired chete, uye, kana zvichidikanwa, imwe yakawedzera isina waya (yevaenzi network kana network yenharembozha). Sei isina waya network isingavimbike zvishoma? Chero Wireless network ine huwandu hwekuchengetedza, kugadzikana uye kuenderana nyaya. Kunyanya njodzi kune kambani yakakomba.
Kuvimbika kunotarisawo chimiro chetiweki. Iyo "Nyeredzi" yepamusoro ndiyo yakanaka iyo yatinofanira kuedza kwairi. "Nyeredzi" inoderedza huwandu hunodiwa hwekuchinja, huwandu hwemitsetse yehunde isina njodzi, uye inorerutsa kuchengetedza. Zviri nyore sei kutsvaga dambudziko mune imwe switch pane akati wandei akapararira mumahofisi, sezvakataurwa nemunyori wenyaya yataurwa pamusoro. Haisi pasina iyo mutsara wekuti "chinja zoo" inoshandiswa.
Asi kazhinji mukuita kuchiri kudikanwa kushandisa chero "fractal star" kana "mixed topology" topology. Izvi zvinokonzerwa nechinhambwe chishoma kubva kune inoshandura midziyo kuenda kunzvimbo yekushanda. Ichi ndicho chikonzero ini ndichitenda kuti optical network inozopedzisira yatsiva yakamonyoroka peya.
Kana zvisingabviri kuisa zvese switch munzvimbo imwechete, zvino zviri nani kushandisa yakasanganiswa topology, nekuti hunde dzese dzichatora nzira dzakasiyana, izvo zvinoderedza mukana wekukuvadzwa panguva imwe chete kune akati wandei.
Kutaura kwehunde. Shanduko dzakabatanidzwa nemitsara yetrunk dzinofanira kugara dziine chiteshi chekuchengetedza, zvino kana mutsara mumwe wakakuvadzwa, kubatana pakati pemanodhi kunoramba kuripo uye hapana kubatana kumwechete kuchaputswa. Iwe unogona kutora nguva yako uye kusimbisazve waya yakakanganisika. Naizvozvo, kune hunde, kunyangwe pazvinhambwe zvipfupi, unogona kushandisa inokurumidza uye yakaonda optical chigamba tambo.
Yechipiri nheyo yekuvaka scs ndeye rationality uye inoshanda. Ihwo hungwaru husingabvumiri kushandiswa kwe "mazuva ano" optics mukubatanidza nzvimbo dzekushanda uye mamwe maturusi emagetsi. Sezvakataurwa nemunyori wechinyorwa chataurwa pamusoro, zvese zvave kushanda patambo yakamonyoroka. Inoshanda zvikuru. Asi kuchine zvishoma zvinogona kushanda kuburikidza neoptical chiteshi pasina mimwe michina. Uye imwe neimwe yekuwedzera mudziyo hausi wengozi chete asiwo mutengo wekuwedzera. Asi ichi chichiri ramangwana. Rimwe zuva, kana mudziyo wega wega une yakavakirwa-mukati yekuona chiteshi, optics inotsiva zvachose tambo dzakamonyoroka.
Rationality uye kushanda kunogonawo kuratidzwa muhuwandu hwe rj45 zvigadziko munzvimbo yebasa. Izvo zvinoshanda kushandisa zvigadziko zviviri panzvimbo. Mutsara wechipiri unogona kushandiswa, semuenzaniso, kubatanidza analogi (yedhijitari) runhare, kana kungoita backup. Iyi ndiyo nzira iyo SCS inowanzogadzirirwa makambani makuru. Kune mabhizinesi madiki uye epakati, zvine musoro kushandisa soketi imwe yekombuta panzvimbo yebasa, sezvo mafoni eIP kazhinji aine madoko maviri - chinongedzo chinopinda uye chechipiri chekubatanidza komputa kuburikidza nayo. Kune network printers, zvinogara zvichikurudzirwa kugadzira imwe nzvimbo yekushandira, uye kuiwana, kana zvichibvira, zviri nyore kune vese vashandi vanoishandisa, semuenzaniso mumakoridho. Munhu ane hunyanzvi mundima yeIT anofanirwa kusarudza kuti chii chinonyanya kukosha - kurongeka kana kuita, nekuti isu tese tinonyatsoziva izvo manejimendi anowanzo sarudza.
Pane imwe pfungwa yakakosha yandingati ine chekuita nekunzwisisa uye kuita. Izvi zvine musoro redundancy. Zvinonyanya kushanda kuve nenzvimbo dzebasa dzakawanda mumahofisi sezvinogona kugarwa nevashandi, pane kuti vangani vari kushanda ipapo parizvino. Pano zvakare, mushandi ane ruzivo ane ruzivo rwemari yekambani uye anonzwisisa kuti munyaya yezvikumbiro zvitsva, anofanira kugadzirisa dambudziko rekushaya nzvimbo.
Uye zvechokwadi, musimboti wekunzwisisa uye kuita kunosanganisira kusarudzwa kwemidziyo uye zvinhu. Semuyenzaniso, kana kambani iri diki uye isina mukana wekushandisa anokwanisa network maneja anokwanisa kushanda neL2 switch, zvine musoro kushandisa ma switch asina kutariswa, nepo panofanira kunge paine hunde yekuchengetedza, kunyangwe isiri kushanda. Hapana chikonzero chekuchengetedza pazvinhu. Kushandisa copper-plated twisted pair panzvimbo yemhangura zvinoreva kuti mumakore mashomanana iwe unovimbiswa kusangana nedambudziko rekubatana kwakaipa. Kuramba mapaneru, fekitori chigamba tambo uye varongi zvinoreva kuti mushure menguva yakati iwe unozopedzisira wava nekuvhiringidzika muwadhiropu, uchigara "uchidonha" zvibatanidza uye oxidation yezvibatanidza. Iwe haufanirwe kusvetuka pane server cabinet futi. Ukuru hukuru haungokubvumiri kuti ugare nemichina yakawanda, asi ichaitawo kuti zvive nyore kuchengetedza.
Usasvetuka patambo dzechigamba. Tambo dzakanaka dzefekitari chigamba dzinofanirwa kuwanikwa munzvimbo dzebasa uye muvhavhavhavha. Kana iwe ukaverenga nguva yakashandiswa crimping connectors uye mutengo wezvinhu, ipapo kutenga fekitari chigamba tambo ichave yakachipa. Mukuwedzera, tambo ichave yakasimba, zvibatanidza zvinogona kunge zvakashata, zvibatanidza zvinokurumidza kuwedzera oxidize, crimping tool inogona kunge yakaipa, ziso rinogona kusviba, uye kune zvimwe zvikonzero zvakawanda zvekusashandisa tambo yakagadzirwa kumba.
Sekuona kwangu, kana pasina chikonzero chekuti nzvimbo yekushanda ishande pa 10G kumhanya, zvinonzwisisika kushandisa twisted pair cable yeboka 5e pane chikamu 6, nokuti haisi kungodhura chete, asiwo yakatetepa, inoshanduka uye naizvozvo. zviri nyore kuisa.
Uye pakupedzisira, musimboti wechitatu kurongeka. Iyo yakakura network, iyo inonyanya kukosha kurongeka mairi. Zvigadziko uye zviteshi zvepatch panels zvinofanirwa kuverengerwa. Kuverenga nhamba kunowanzotanga kubva kumabasa kubva kuruboshwe kuenda kurudyi kubva pamusuwo wekamuri. Panofanira kunge paine chirongwa chepasi chakatenderwa chine nzvimbo uye manhamba ezvitoro.
Izvo ndezvekurongeka uye kwete zvekuparadzaniswa kwemuviri wemanetiweki ayo zvigamba mapaneru anoshandiswa. Kana munyori we "kanopfuura kamwe ataurwa" chinyorwa achifunga kuti hapana chakakosha chekuchinja muwadhiropu yake, saka isu hatigone kuwana izvi.
Ndizvo zvose. Aya misimboti matatu akakosha anosarudza chero mapurojekiti angu eSCS. Muchikamu chino handina kukwanisa kubata pane zvese, zvimwe ndakapotsa zvakawanda, uye ndinogona kunge ndakanganisa pane imwe nzvimbo. Ndinogara ndakagadzirira kurukurirano inovaka kana ndikapiwa kokero kana kuti mutsamba dzomunhu oga.
