Lan naSan Starce Local Area Network network network network, zvakateerana, uye ese ari ekutanga ekuchengetedza nzira yekushandisa mukushandiswa kwakapararira nhasi.
Lan ndeye muunganidzwa wemakomputa uye peripheral vanogovana neyakagadzirwa kana isina waya yekutaurirana yekubatanidza kune maseva inowanikwa munzvimbo dzakasiyana dzenzvimbo. San in network, kune rumwe rutivi, inopa yakakwirira-yekumhanyisa yekubatanidza network yakazvimirira, kubvumira kusevha kusanzwisisika kwemasangano akawanda ane akasiyana siyana ekuchengetedza midziyo.
Nekudaro, zvikamu zviviri zvakakosha zvinoshandiswa mune yekombuta network network kune lan switches uye san switches. Kunyangwe switches uye san switches ese ari maviri nzira yekukurukurirana data, ivo vane dzimwe misiyano, saka ngatitarisei pasi apa.
1 Chii chinonzi lan kuchinjira?
Lan kuchinjika inzira yekuchinjika-yekuchinja inoshandiswa pakutapurirwa nemapepa pakati pemakomputa pane lAn mukati mekodhi yemunharaunda yemunharaunda. Iyi nzira inoita basa rakakosha mune network dhizaini uye rinogona kugadzirisa zvakanyanya lan kunyatsoita uye kuderedza bandwidth contrachints. Kune marudzi mana eLan achinja:
Multilayer ichichinja MLS;
Layer 4 swaching;
Layer 3 switching;
Layer 2 switching.
Lan Shandura basa sei?
A LAn switch ndeye ethernet switch iyo inoshanda kubva paIP protocol uye inopa yekubatanidza inokonzeresa pakati pevatumwa uye vanogashira kuburikidza neinonhuwirira network yemadombo uye zvinongedzo. Urongwa uhwu hunobvumira huwandu hukuru hwekupedzisira vashandisi kugovana netiweki zviwanikwa. Lan Switches Act Syapaketi Switches uye inogona kubata akawanda data transmistions panguva imwe chete. Ivo vanoita izvi nekuongorora iyo kero yekuenda kweiyo yega yega data chimiro uye pakarepo kuendesa kune yakatarwa chiteshi chakabatanidzwa neyakagadzirirwa kugashira mudziyo.
Chikamu chikuru cheLan switch ndechekuzadzisa izvo zvinodikanwa zveboka revashandisi kuitira kuti vakwanise kuita pamwe chete kuwana zviwanikwa uye kutaurirana kusanzwisisa. Nekushandisa kugona kweLan switches, chikamu chikuru cheti traffic chinogona kuwanikwa muzvikamu zvakarukwa. Ichi chikamu chekubatanidza zvinobudirira chinodzora zvakazara lAn constimession, zvichikonzera mudhara yekutumira data uye network yekushandisa.
2 Chii chinonzi san kuchinja?
Kuchengetedza Area Network San switching nzira yakasarudzika yekugadzira kubatana pakati peServers uye yakagovaniswa madziva ekuchengetedza echinangwa chekutungamira kwedata rekuchengetedza.
NaSan Switch, zvinokwanisika kugadzira yakakura-chiyero, yakakwira-yekumhanyisa storage satches iyo inobatanidza maServers akawanda uye kuwana huwandu hwakawanda hwe data, kazhinji kusvika petabheti. Mukushanda kwavo kwekutanga, San anokwenenzvera zvakanyatsoronga traffic pakati peServers uye zvishandiso zvekuchengetedza nekuongorora mapaketi uye kuitisa kuti vaendere kumagumo. Nekufamba kwenguva, network nharaunda yekuchengetedza switch yakabva yashanduka kuti ishandise zvinhu zvepamberi senge nzira yekudzorerwa, network diagnostics, uye otomatiki bandwidth yekunzwa.
Fiber chiteshi chinotsvedza sei basa?
Fiber chanzuru switch chinhu chakakosha munzvimbo yekuchengetedza network San iyo inobatsira kuendesa data zvakanaka pakati servers uye michina yekuchengetedza. Iyo switch inoshanda nekugadzira yakakwira-yekumhanyisa yakavanzika network yakagadzirirwa kuchengetedza data uye kudzoserwa.
Pazviri, chichinja fiber switch inotsamira pane yakakosha Hardware uye software yekugadzirisa uye yakananga data traffic. Inoshandisa iyo Fiber Channel protocol, iyo yakasimba uye yakavimbika yekutaurirana protocol yakagadziridzwa kune san nharaunda. Sezvo data inotumirwa kubva kune server kune iyo yekuchengetedza mudziyo uye inokonzeresa, inokatyamadzwa muFiber Channel mapuranga, inoverengera kutendeka kwedata uye nekumhanya-kumhanya.
Iyo switch switch inoshanda semupurisa wemigwagwa uye inosarudza nzira yakanakisa yedata kufamba kuburikidza neSan. Iyo inoongorora iyo sosi uye yekuenda kero muFiber Channel mapepa ekunyorera eckets eckets. Uyu akangwara routing anoderedza latency uye kugunun'una, anoona kuti data inosvika kunzvimbo yayo nekukurumidza uye nekuvimbika.
Chaizvoizvo, fiber chiteshi chinonhuwira orchestrate kuyerera kwedatha mune San, kururamisa kuita uye kuvimbika munzvimbo dzakagadzirirwa data.
3 Ivo vakasiyana sei?
Kufananidza switch kushandura kune switch kunogone kufunga nezve sekufananidza sanch switch kune network switch, kana fiber chanzuru switch kusvika kuEthernet switch. Ngatitarisei kutarisisa musiyano mukuru pakati peLan Switches uye San Switches.
Kushanda Kushanda
Lan Switched pakutanga yakagadzirirwa chiratidzo cheChirungu uye fddi network uye yakazotsiviwa naEthernet. Lan switch inobata basa rakakosha mukuvandudza kugona kwakazara kwerenanani uye kugadzirisa zvinobudirira matambudziko aripo. MaLans anokwanisa kubatanidza zvishandiso zvakasiyana-siyana semaseva faira, anodhinda, dhizaini, etc., uye lan switch anokwanisa kubata traffic pakati peiyi magumo akasiyana.
Uye switch switch yakagadzirirwa yakakwirira-performance network yekuona yakaderera-latency uye yekurasikirwa data kutamisa data. Iyo yakarongedzwa nokungwarira kubata zvinobudirira kutakura mitoro inorema, kunyanya mune yakakwirira-mashandiro fiber chitubu network. Kunyangwe ethernet kana fiber chiteshi, chengetedzo nzvimbo network switches yakatsaurirwa uye yakarongedzwa kuti ibate traffic yekuchengetedza.
Kusiyana kwemisiyano
Kazhinji, lan switches inoshandisa marara uye fiber interfaces uye inoshanda pane ip-based ethernet network. Layer 2 Lan switching inopa mabhenefiti ekukurumidza data kuendesa uye mashoma latency.
Iyo inodakadza mune inoenderana seVOIP, Qos uye Bandwidth Kuzivisa. Layer 3 Lan switch inopa yakafanana nezvinhu zvakafanana nemaitiro. Kana iri iyo lan 4 lan switch, iyo shanduro yepamberi yeiyo lan switch iyo inopa maficha ekuwedzera, IPX. zvinodiwa.
San Switch anovakwa pane hwaro hweIsST Stoge Storage Networks, inosanganisira fiber chiteshi uye iscs tekinoroji. Chinhu chakanyanya kukosha ndechekuti San switches inopa yepamusoro yekuchengetedza kugona pamusoro peLan switch. Fiber Channel Switches inogona zvakare kuve ethernet switches.
Zvakakodzera, iyo Ethernet-yakavakirwa San switch yaizozvitsaurirwa kugadzirisa yekuchengetedza traffic mukati me IP yekuchengetedza nzvimbo network, nekudaro ichisvika pakufungidzira maitiro. Zvakare, nekubatana San Switches, iyo yakawedzera san network inogona kuumbwa kuti ibatanidze akawanda maseva uye zvigaro zvekuchengetedza.
4 Ndinosarudza sei switch chaiyo?
Kana uchifunga nezve lan vs, san, sarudzo yeiyo lan switch kana switch switch inova yakaoma. Kana zvaunoda zvinosanganisira faira-kugovana protocol yakadai se ipx kana applatalk, ipapo ip-based lan switch ndiyo yakanakisa sarudzo yekuchengetedza mudziyo wekuchengetedza. Zvekare, kana iwe uchida switch yekutsigira fiber chiteshi-chakavakirwa, iyo network nharaunda kuchengetedza switch inokurudzirwa.
Lan switches inofambisa kutaurirana mukati me lan nekubatanidza zvishandiso mukati meiyo network imwechete.
Fiber Channel Switches, kune rumwe rutivi, inonyanya kushandiswa kubatanidza michina yekuchengetedza kune maseva yekuchengetedza kugona uye data retrizavel. Aya majira anosiyana mutengo, kusawirirana, topology, chengetedzo, uye yekuchengetedza kugona. Iko kusarudzwa pakati pawo kunoenderana nezvakaitika zvekushandisa.
Lan Switchs isingadhuri uye nyore kusarudza, nepo san switches inodhura uye inoda kugadziriswa kwakaoma kunzwisisa.
Muchidimbu, lan switches uye san switches mhando dzakasiyana dze network switches, imwe neimwe ichiridza iyo yakasarudzika basa mune network.
