I-LAN kunye neSan imi yenethiwekhi yendawo yendawo kunye nenethiwekhi yokugcina, ngokwahlukeneyo, kwaye zombini ziinkqubo eziphambili zokugcina izinto zokugcina indawo ekusebenziseni okubanzi namhlanje.
I-LAn yingqokelela yeekhompyuter kunye nee-peripherals ezabelana ngekhonkco lonxibelelwano olunentambo okanye ezingenazingcingo kumaseva akwiisethi ezifumaneka kwiindawo ezahlukeneyo zendawo. I-San kwinethiwekhi, kwelinye icala, ibonelela ngoxokolo oluphezulu kwaye yenzelwe uthungelwano lwabucala, ivumela uthungelwano olungenamthungo, ivumela uluhlu olungenamthungo lweeseva ezininzi ezinesixhobo ezahlukeneyo sokugcina.
Kananjalo, ezi zinto zimbini ziphambili ezisetyenziswa kwi-Computer Aggart Punterpart yeKhompyutha i-win switches kunye neSan Switches. Nangona i-Switches kunye neSan Switches zizo zombini iindlela zonxibelelwano lwedatha, zineyantlukwano, ke masijonge ngezantsi.
1 Yintoni i-LAN iguqula?
Ukutshintsha kwe-LAN yindlela yokutshintsha ipakethi esetyenziselwa ukuhanjiswa kweepakethi phakathi kweekhompyuter kwi-LAN kwinethiwekhi yendawo. Obu buchule budlala indima ebalulekileyo kuyilo lwenethiwekhi kwaye lunokuphucula ngokufanelekileyo i-LAN kwaye kwaye inyanzelise i-Bandwidth Bandwidth. Kukho iintlobo ezine zokutshintsha kwe-LAN:
Ukutshintsha kwe-Mulayer Mls;
Ungqimba ukutshintsha kwe-4;
Ungqimba ukutshintsha;
Ungqimba ukutshintsha kwe-2.
Isebenza njani i-lan switch?
Ukutshintsha kwe-LAN kukuSupolf I-E-Elernet isebenza ngokusekwe kwiProtocol ye-IP kwaye ibonelela ngoqhagamshelo oluguqukayo phakathi kwabathumeli kunye nabamkeli ngothungelwano lwamachweba kunye namakhonkco. Eli lungiselelo livumela inani elikhulu labasebenzisi bokuphela ukuze babelane ngezixhobo zenethiwekhi. I-Lan Switches isebenza njengepakethi yepakethi kwaye inokuphatha ukuhanjiswa kwedatha ezininzi ngaxeshanye. Bakwenza oku ngokuhlola idilesi yendawo yokufika kwesakhelo sedatha nganye kwaye ngoko nangoko ikhokelela kwisibuko esithile esinxulumene nesixhobo esifunyanisiweyo.
Indima ephambili yokutshintsha kwe-LAN kukufezekisa iimfuno zeqela labasebenzisi ukuze bakwazi ukufikelela ngokudibeneyo kunye nokunxibelelana ngokungakhathali. Ngokusebenzisa amandla e-winsing ye-LAN, inxenye enkulu yendlela yenethiwekhi inokuthi ibekwe kwicandelo le-compact len. Esi sahlulo sinciphisa ngokufanelekileyo i-LAN iyonke i-LAN, kukhokelela ekudluliseleni idatha yokudluliselwa kwedatha kunye nokusebenza kwenethiwekhi.
2 Yintoni i-San Swip?
Ukutshintsha kwendawo ye-San Swinch yindlela ekhethekileyo yokudala uqhagamshelo phakathi kweeseva kunye neeseva zokugcina izinto ezisabelayo zokwenza lula ukuhanjiswa kwedatha enxulumene noko.
NgeSan Switches, kunokwenzeka ukuba wenze uthungelwano olukhulu, isantya esiphezulu sokuqhagamshela iiseva ezininzi kwaye ufikelele kwimali enkulu yedatha, ihlala ifikelela kwi-petbytes. Kwintsebenziswano yabo esisiseko, i-San Switches ilungelelanisa ukugcwala kwezithuthi phakathi kweeseva kunye nezixhobo zokugcina ngokuhlola iipakethi kwaye zikhokelele kwiindawo ezimiselweyo ezimiselweyo. Ixesha elingaphezulu, i-switches yendawo yokugcina inethiwekhi ivele ukubandakanya izinto eziphambili ngokubandakanya indlela yokuphinda ihlawulwe, inethiwekhi yenethiwekhi, kunye ne-bandwidth bandlidth.
I-fiber witches switches Umsebenzi?
Itshaneli ye-fiber ye-fiber licandelo eliphambili kwinethiwekhi yendawo yokugcina iSan enceda ukutshintshela idatha ngokufanelekileyo phakathi kweeseva kunye nezixhobo zokugcina. Ukutshintsha okusebenza ngokwenza inethiwekhi ehamba ngesantya esiphezulu yenzelwe ukugcinwa kwedatha kunye nokubuyiswa kwemali.
Kwinkalo yayo, i-facking ye-fiber ixhomekeke kwi-hardware ekhethekileyo kunye nesoftware yokulawula kunye nokuhambisa itrafikhi yendlela. Isebenzisa iProtokholi ye-fiber ye-fiber, i-protocol yoNxibelelwano ePhakathi ilungiselelwe indawo yeSan. Njengoko idatha ithunyelwe kwiserver kwisixhobo sokugcina kunye ne-Vice Dissana, iqhutywa kwi-fibren charnel fremps, ukuqinisekisa ukuthembeka kwedatha kunye nosulelo ngesantya esiphezulu.
I-SAN STSTSET isebenza njengoMoya weTrafiki kwaye ichaza eyona ndlela ilungileyo yedatha yokuhamba eSan. Ivavanya umthombo kunye nedilesi yendawo ekuyiwa kuyo kwi-fibrennel yecannel ye-channel yentshukumo efanelekileyo yeepakethi. Oku kuqonda ukuqiqa kuncitshiswa i-tendocy kunye nokuxinana, ukuqinisekisa ukuba idatha ifikelela kwindawo eya kuyo ngokukhawuleza kwaye ngokuthembekileyo.
Ngokuyintloko, i-fiber Channels itshintsha i-richestrate i-datiment yedatha kwi-San, inyanzelise ukusebenza kunye nokuthembeka kwiindawo ezinemifanekiso.
3 Bahluke njani?
Ukuthelekisa ukutshintshela kwe-LAN ukuya kwi-San Switch kunokucinywa njengokuthelekisa ukutshintshela kwe-San kwi-switch yenethiwekhi, okanye i-fiber witch switch switch switch switch switch switch switch. Makhe siqwalasele umahluko ophambili phakathi kwe-hin switches kunye neSan Switches.
Isicelo somahluko
I-Lan Switch yayenzelwe ukuba ibe yeyokhenketho kunye neenethiwekhi ze-FDDI kwaye zatshintshwa ngu-Ethernet. I-Lan Switch idlala indima ebalulekileyo ekuphuculeni ukusebenza kwe-lans kwaye isombulule ngokufanelekileyo imiceli mngeni ekhoyo. I-Lans inokuthi inxibelelane nezixhobo ezingenamthungo ezifana neeseva zeFayile, abashicileli, ukugcinwa kweedesktos, iidesika, njl njl.
Kwaye i-Switch Switch yenzelwe iinethiwekhi zentsebenzo eziphezulu zokuqinisekisa ukudluliselwa kwendlela ephantsi kunye nokudluliselwa kwedatha engenako ilahleko. Yenziwe ngononophelo ukuba ulawule ngokufanelekileyo imithwalo enzima yentengiselwano, ngakumbi kwinethiwekhi ye-fiber ye-fiber ephezulu. Enoba i-ethernet okanye i-fiber Channel, i-switch yogcino yogcino lwendawo inikezelwe kwaye ilungiselelwe ukuphatha itrafikhi yokugcina.
Umahluko weNtsebenzo
Ngokwesiqhelo, ukutshintsha kwee-LAN Sebenzisa isinxibelelanisi sobhedu kunye ne-fiber kwaye isebenza kwinethiwekhi ye-IP-esekwe kwi-IP. Utshintshe 2 Ukutshintshela kwe-Lan Disction kubonelela ngeenzuzo zokudluliselwa kwedatha ngokukhawuleza kunye nokulandelwa kwendlela encinci.
Igqwesa kwiimpawu ezinje nge-voip, i-QOS kunye nengxelo ye-bandwidth. Ungqimba 3 I-Lan Switches inika izinto ezifanayo njengee-routers. Ngokubhekisele kwi-4 lan switch, luhlobo oluphambili lwe-Lant Switch onokongezwa kwe-telnet kunye ne-ftp.in, i-TCP, i-TCP ye-Apple i-IPX
I-San Switches Yakha kwisiseko senethiwekhi ye-ISCI, ebandakanya ijelo le-fiber kunye neTekhnoloji ye-ISCI. Elona nqanaba libalulekileyo kukuba iSan Switches ibonelela ngezakhono zokugcina eziphezulu ngaphezulu kwe-win. I-fiber wingnel switches inakho ukuba switches.
Ngokufanelekileyo, ukutshintshela kwe-ernet-sen se-e-Elernet kuya kukhethwa kulawulo lokuGcina ukuGcina i-IP yendawo yokugcina i-IP, ngenxa yoko kuqinisekisa ukusebenza kwangaphambili. Kwakhona, ngokutshintshana eSan Switches, inethiwekhi ebanzi ye-San inokusekwa ukudibanisa iiseva ezininzi kunye namazibuko okugcina.
4 Ndiyikhetha njani i-switch elungileyo?
Xa ujonga i-LAN VS. San, ukhetho lwe-Lan Switch okanye i-SAS Switch ibalulekile. Ukuba iimfuno zakho zibandakanya iiprothokholi zokwabelana ngefayile ezinje nge-IPX okanye i-AppleTalk, emva koko i-IP-iseke i-IP-esekwe kwi-IP-esekwe kwindawo elungileyo yesixhobo. Kwelinye icala, ukuba ufuna ukutshintshelwa ukuze uxhase ugcino lwe-fiber ye-fiber ye-fiber ye-fiber, indawo yokutshintshela yenethiwekhi iyacetyiswa.
Ukutshintsha kwee-LAN ngokuququzelela unxibelelwano ngaphakathi kwe-LAN ngokuqhagamshela izixhobo ngaphakathi kwenethiwekhi enye.
I-fiber ritches switches, kwelinye icala, ngokuyintloko zisetyenziselwa ukudibanisa izixhobo zokugcina kwiiseva zokugcina ezifanelekileyo kunye nokubuyiswa kwedatha. Ezi tshisi ziyahluka kwiindleko, ukukhululeka, i-topology, ukhuseleko, kunye nokugcinwa komthamo. Ukukhetha phakathi kwabo kuxhomekeke kwiimfuno ezithile zokusetyenziswa.
I-Lan Switches ayibizi kwaye kulula ukuyiqwalasela, ngelixa iShan Switches ibiza kakhulu kwaye ifuna ukuba kubekho iingxaki ezininzi.
Ngamafutshane, ukutshintshiselana kwee-LAN kunye neSan Switches ziintlobo ezahlukeneyo zenethiwekhi, nganye nganye idlala indima ekhethekileyo kwinethiwekhi.
