    Umahluko phakathi kokutshintsha kwe-Managed Vs engalawulwayo kwaye uthenge eyiphi?

    Ixesha lokuposa: Oct-19-2022

    Iiswitshi ezilawulwayo ziphezulu kunezo zingalawulwayo ngokwemigaqo yokusebenza, kodwa zifuna ubuchule bomlawuli okanye injineli ukuze baqonde ngokupheleleyo amandla abo. Ulawulo oluchanekileyo ngakumbi lothungelwano kunye nezakhelo zabo zedatha zenziwe ukuba zisebenziseke ngokulawulwatshintsha. Kwelinye icala, iiswitshi ezingalawulwayo zivumela olona hlobo lubalulekileyo lonxibelelwano phakathi kwezixhobo kuthungelwano.

    Kweli nqaku, siza kuphonononga umahluko phakathi kotshintsho olulawulwayo nolungalawulwayo.

     

    Yintoni elawulwayotshintsha?

    Iiswitshi ezilawulwayo zibonelela ngezakhono ezifanayo njengokutshintsha okungalawulwayo, kunye nenzuzo eyongezelelweyo yokhetho lolawulo.
    Ulawulo olubanzi lwenethiwekhi, ukujonga, kunye neenketho zoqwalaselo zikunika umyalelo omkhulu ngaphezulu kokuhamba kwedatha yenethiwekhi yakho yasekhaya.
    Ngombulelo kubhetyebhetye olubonelelwa ngotshintsho olulawulwayo, izibuko ngalinye elikwisixhobo linokuhlengahlengiswa ngokwalo ukuze lihambelane neemfuno zakho. Izibonelelo ziquka iindlela ezichane ngakumbi zokugcina i-tab kwimo yenethiwekhi yakho kunye noluhlu olubanzi lweenketho zokulungisa ukuseta kwayo kwiimfuno zakho.
    Ngokuqhelekileyo, okutshintshaimodeli iya kuba ne-web-based okanye ujongano lwelayini yomyalelo evumela ukufikelela kude kujongano lolawulo lwesixhobo. Ungangena kwinethiwekhi okanye wenze uhlengahlengiso ngaphandle kokuba kwigumbi elinye njengetshintshangokwayo.

     

    Iimpawu zolawulo olulawulwayo nokubekwa iliso ngokupheleleyotshintsha:

    Uluhlu olubanzi lwee-topology, kubandakanywa iProtocol ye-Spanning Tree, i-Ring, i-Mesh, i-Stacking, kunye ne-Aggregation, ziyafumaneka ukuthunyelwa kwayo, ukwandisa ukuphindaphinda kwayo kunye nokuthembeka. Ukusebenzisa ulawulo olukude kunye nolawulo lwe-software-defined networking (SDN), kunokwenzeka ukubeka iliso kunye nokuhlalutya idatha ye-traffic, ukulawula izixhobo zokugqibela, kunye nokujongana neengxaki nakwiinethiwekhi ezinkulu. Izinto ezininzi zokhuseleko zinokulawula ukuba ngubani ofikelela kwinethiwekhi, ukubeka iliso ekuhlaselweni kunye nokunceda ukulungisa nakuphi na ukuphulwa okwenzekayo. Umgangatho weNkonzo (QoS) unceda ukubeka phambili i-traffic kunye nokudibanisa izixhobo ezifanayo kunye ukuze bonke benze uninzi lwezixhobo zenethiwekhi.

     

    Yintoni engalawulwayotshintsha?

    Umsebenzi owodwa wokungalawulwatshintshakukudibanisa izixhobo ezenziwe nge-Ethernet kunye kuthungelwano ukuze bakwazi ukutshintshiselana ngedatha enye kwenye. Abanye abantu babona utshintsho olungalawulwayo “njengendoda ephakathi.” Ngelixa yongeza ngokufanelekileyo amachweba amaninzi kwinethiwekhi yakho, ayiphumezi enye into kwaye ayibonakali ngokwenene.

    Ukutshintsha okungalawulwayo akukwazi ukulawula itrafikhi yenethiwekhi, kodwa kulula ukuyihambisa kuba ayifuni uqwalaselo. Umzamo kuphela ofunekayo kukuyiplaga. Ukutshintsha okungalawulwayo kusetyenziswa rhoqo kwiisetingi zemizi-mveliso ukudibanisa izixhobo ezinqamlekileyo okanye ukongeza okwethutyana amaqela ezixhobo kwinethiwekhi enkulu.

    Iiswitshi ezingalawulwayo zihlala zinexabiso eliphantsi kunoogxa babo abalawulwayo, nangona kunjalo oku kungenxa yokuba abanazo izakhono eziphambili ezifumanekayo kwiiswitshi ezilawulwayo.

     

    Uqhagamshelo olungalawulwayo, oluxabisa kancinci lubandakanya ezi mpawu zilandelayo:

    Ulungelelwaniso oluzenzekelayo kunye nokusebenza xa kuplagiwe. Kona kuphela ulungelelwaniso olulula lwenethiwekhi, njengenkwenkwezi kunye netyathanga ledaisy, iya kusebenza. Amandla okuvelisa nokugcina iitafile zeedilesi ze-MAC ziphucula ulawulo lwezithuthi kwii-hubs ze-Ethernet ngeendlela ezininzi. Akukho mahluko phakathi kwendlela utshintsho oluphatha ngayo i-multicast kunye ne-traffic traffic, enokuthi ikhokelele kwimiba yengxinano emandla eyaziwa ngokuba ziziphango zokusasaza.

     

    Umahluko phakathi kwe-Maged Vs engalawulwayotshintsha:

    Indlela esetyenziswayo ngowona mahluko uphambili phakathi kokulawulwa nokungalawulwayotshintsha. Ulawulotshintshainika umyalelo kubalawuli bomsebenzi womnatha, ebavumela ukuba babeke phambili i-LAN traffic kwaye balawule ukuhamba kwayo. Ngokuchasene noko, into engalawulwayotshintshaifuna nje ukuba iplagwe kwaye ivulwe. Ivumela izixhobo ze-LAN ukuba zibe neencoko zabucala kunye nomnye.

    Uthungelwano alunakutshintshwa ngongalawulwayotshintsha, kodwa kulula ukuyisebenzisa. Ngenxa yoko, yamkelwa jikelele ngamashishini amatsha. Nangona kunjalo, ilawulwatshintshayenza ulawulo lwe-LAN, uqwalaselo, kunye nokubeka iliso. Ukongezelela, ukuguqulwa kokutshintsha okulawulwayo kuququzelela ukuphindaphinda kwedatha kunye nokubuyiselwa kwimeko yesixhobo okanye ukungaphumeleli kwenethiwekhi.

    Enye yeempawu zokhuseleko ezisisiseko zokutshintsha okungalawulwayo sisivalo sezibuko esitshixwayo, esithintela ukufikelela okungagunyaziswanga kwisixhobo. Iiswitshi ezilawulwayo, kwelinye icala, zineempawu zokhuseleko ezomeleleyo. Iyakwazi ukuvala imisonto yomsebenzi, idatha ekhuselekileyo, kwaye ilawule izicwangciso zonke ngokubeka iliso kwinethiwekhi kunye nezakhono zokulawula.

    Ayiyomfihlo into yokuba iiswitshi ezingalawulwayo zinexabiso eliphantsi kunoogxa babo abalawulwayo. Ukongeza, ixabiso liyahluka ngokusekelwe kwiintlobo zamazibuko ezikhoyo.

    Kwiimeko ezininzi, engalawulwatshintshalolona khetho lungcono kuthungelwano oluncinci, olufana nolwasekhaya okanye ishishini elincinci. Amashishini anomzila womnatha obanzi okanye axhomekeke kwiziko ledatha kwaye anokuzuza kulawulo olungqongqo kwitrafikhi yenethiwekhi kufuneka athathele ingqalelo ulawulo olulawulayo.tshintsha.

    Umahluko phakathi kwe-Management Vs engalawulwayo iswitshi kwaye uthenge eyiphi

    Ukulawulwa kweeVs ezingalawulwayotshintshakwaye uthenge eyiphi?

    Zininzi izinto ekufuneka ziqwalaselwe xa ukhetha into elawulwayotshintsha. Thetha nengcali IT oqeqeshiweyo okanye umlawuli womnatha. Oku kulandelayo yeminye imibuzo ekuluncedo ukuyiqwalasela xa uthenga ngokubanzi.

    ezinje ngotshintsho lufakwe kweyiphi indawo? Kubalulekile ukwazi ukuba bangaphi abantu kunye nezixhobo eziya kufikelela kwinethiwekhi ngaxeshanye. Ngaba itrafikhi yenethiwekhi inokulawulwa, kwaye uqwalaselo lwenethiwekhi luyafuneka? Sesiphi isizathu sokuba ufuna ukusebenzisa iiswitshi?

    Kuqhelekile ukuba uthungelwano olunezixhobo eziqhagamshelwe ezingaphantsi kweshumi elinesibini ukusebenzisa ezingalawulwayotshintsha. Ngaphaya koko, akukho mfuneko yokhuseleko nolawulo. Iiswitshi ezilawulwayo zibonelela ngokuguquguquka okukhulu kunye nokusebenza kunoogxa babo abangalawulwayo. Ibona ukusasazwa ngokubanzi kwiimeko zamaziko njengezibhedlele, izikolo, kunye nee-arhente zikarhulumente.
