Munyika inogara ichishanduka yetekinoroji, humwe hutsva hunomira pachena senguva dzakakosha dzinogadzirisa patsva mamiriro ekutaurirana edhijitari. Imwe hunyanzvi hwakadaro ndeye network switch, chishandiso chakakosha mumabhizinesi nemaindasitiri network. Iko kusikwa kwetiweki switch kwakaratidza shanduko huru munzira iyo data inofambiswa uye inogadziriswa, zvichikonzera kuti iwedzere kushanda, scalable uye yakavimbika network. Ichi chinyorwa chinotarisa kune kwakabva network switch uye nekukanganisa kwavo kwakadzama pamanetiweki azvino.
Kwakabva Network Swichi
Pfungwa yekuchinja kwetiweki yakabuda mukutanga 1990s mukupindura kuoma kuri kuwedzera uye zvinodiwa zvemakomputa network. Vasati vagadzirwa, ma network ainyanya kutsamira pamahubs nemabhiriji, ayo, kunyange achishanda, aive nemiganhu, kunyanya maererano ne scalability, kunyatsoita, uye chengetedzo.
Semuenzaniso, hubhu chinhu chiri nyore chinotumira data kune ese maturusi panetiweki, zvisinei neanotarisirwa kugamuchira. Izvi zvinotungamira kunetiweki kusangana, kusashanda, uye njodzi dzinogona kuitika nekuti zvese zvishandiso zvinogashira mapaketi ese, kunyangwe ayo asiri avo. Mabhiriji akapa kumwe kuvandudzwa nekukamura network muzvikamu, asi ivo havasati vakwanisa kubata data iri kuwedzera kana kupa hutongi hunodiwa nemanetiweki azvino.
Nekuona matambudziko aya, mapiyona enetwork akatsvaga mhinduro yaigona kubata data traffic zvine hungwaru. Kuongorora uku kwakatungamira kukudziridzwa kwekutanga network switch, zvishandiso zvaigona kungotungamira data pakiti kune yavo yavanoda kuenda, zvakanyanya kuvandudza netiweki kunyatsoshanda uye chengetedzo.
yekutanga network switch
Yekutanga kutengeserana yakabudirira network switch yakatangwa muna 1990 naKalpana, kambani diki yetiweki. Kalpana's invention yaive multiport mudziyo waishandisa tekinoroji inonzi "frame switching" kunangisa mapaketi kune chaiwo madoko zvichienderana nekwaakaenda. Ichi chitsva chinoderedza zvakanyanya zvisina kufanira data traffic panetiweki, ichigadzira nzira yekukurumidza uye yakavimbika kutaurirana.
Kalpana's network switch yakakurumidza kuve yakakurumbira uye kubudirira kwayo kwakakwezva kutarisa. Cisco Systems, mutambi mukuru muindasitiri yetiweki, akawana Kalpana muna 1994 kubatanidza tekinoroji yekuchinja mumutsara wechigadzirwa. Kutorwa kwacho kwakaratidza kutanga kwekutorwa kwakapararira kwema network switch kutenderera pasirese.
Impact pawebhu yemazuva ano
Kuunzwa kwetiweki switches kwakashandura networking munzira dzakati wandei dzakakosha:
Kuwedzera kugona: Kusiyana nehubhu inotepfenyura data kune ese maturusi, hub inongoendesa data kune chaiwo maturusi anoida. Izvi zvinoderedza zvakanyanya kusangana kwetiweki uye zvinobvumira kushandiswa kwakanyanya kwebandwidth.
Kudzivirirwa kuchengetedzeka: Nekudzora kuyerera kwedata, switch inoderedza mukana wekutora data, ichipa yakachengeteka network nharaunda.
Scalability: Network switch inogonesa kugadzirwa kweakakura, akanyanya kuomarara network, achibvumira masangano kuyera dhijitari zvivakwa pasina kukanganisa kuita.
Tsigiro yematekinoroji echizvino-zvino: Manetiweki switch ashanduka kuti aenderane nekufambira mberi kwetekinoroji, achitsigira kukurumidza kutamisa data, Simba pamusoro peEthernet (PoE), uye epamberi manejimendi manejimendi masimba.
Iko kushanduka kwe network switch
Network switch yakave nekushanduka kukuru kubva pakuvambwa kwavo. Kubva kuBasic Layer 2 switch inobata nyore kutumira data kune advanced Layer 3 switch iyo inosanganisira kugona kwenzira, tekinoroji inoenderera mberi kuzadzisa zvinodiwa zviri kukura zvemanetiweki azvino.
Nhasi, maswiti etiweki akakosha mukushanda kwenzvimbo dzedata, mabhizinesi network, uye nharaunda dzeindasitiri. Vanotsigira zvakasiyana-siyana zvekushandisa, kubva pakubatanidza zvishandiso zveIoT uye kusimbisa zvivakwa zvine hungwaru, kugonesa yakakwirira-yekukurumidza kuwana Internet uye kufambisa makore computing.
Tichitarisa kune ramangwana
Sezvo isu tichienda mberi mukati menguva yeshanduko yedhijitari, basa retiweki switch richaramba richishanduka. Nekuuya kwe5G, edge computing uye Internet yeZvinhu (IoT), kudiwa kwesimba uye inoshanduka network mhinduro inongowedzera. Network switch ine kugona kuchinjika kumatambudziko matsva aya uye icharamba iri pamberi pekusimudzira uku, kuve nechokwadi chekuti data inogona kuyerera isina musono, yakachengeteka uye nemazvo munyika yedu iri kuramba yakabatana.
mukupedzisa
Kuberekwa kwetiweki switch imvura yakadzika munhoroondo yekutaurirana kwedhijitari. Yakashandura nzira iyo data inotungamirwa uye kufambiswa pamusoro pemanetiweki, ichiisa hwaro hweiyo yepamusoro, scalable uye yakachengeteka network yatinovimba nayo nhasi. Sezvo tekinoroji ichienderera mberi, network switch pasina mubvunzo ichaita basa repakati mukuumba ramangwana rekubatana kwepasirese.
