Ma switch oyendetsedwa ndi apamwamba kuposa osayendetsedwa malinga ndi magwiridwe antchito, koma amafunikira ukadaulo wa woyang'anira kapena mainjiniya kuti azindikire zomwe angathe.Kuwongolera bwino kwambiri kwamanetiweki ndi mafelemu awo a data kumatheka pogwiritsa ntchito switch yoyendetsedwa.Kumbali ina, ma switch osayendetsedwa amalola kulumikizana kofunikira kwambiri pakati pa zida zapa netiweki.
M'nkhaniyi, tiwona kusiyana pakati pa ma switch oyendetsedwa ndi osayendetsedwa.
Kodi switch yoyendetsedwa ndi chiyani?
Zosintha zoyendetsedwa zimapereka kuthekera kofanana ndi masiwichi osayendetsedwa, ndi phindu lowonjezera la zosankha zowongolera.
Kuwongolera kwatsatanetsatane kwamanetiweki, kuyang'anira, ndi kusanja zosankha kumakupatsani mphamvu yayikulu pamayendedwe a netiweki yanu yakunyumba.
Chifukwa cha kusinthasintha komwe kumaperekedwa ndi ma switch oyendetsedwa, doko lililonse pazida likhoza kusinthidwa payekhapayekha kuti ligwirizane ndi zosowa zanu.Ubwino umaphatikizapo njira zolondola kwambiri zowonera momwe netiweki yanu ilili komanso njira zingapo zosinthira kukhazikitsidwa kwake mogwirizana ndi zosowa zanu.
Kawirikawiri, chitsanzo chosinthirachi chidzakhala ndi mawonekedwe a intaneti kapena mzere wa malamulo omwe amalola mwayi wopita kutali ndi mawonekedwe oyendetsera chipangizochi.Mutha kuyang'ana pa netiweki kapena kusintha popanda kukhala m'chipinda chimodzi monga chosinthira chokha.
Mawonekedwe a switch yomwe imayendetsedwa bwino ndikuwunikidwa:
Mitundu yambiri yama topology, kuphatikiza Spanning Tree Protocol, Ring, Mesh, Stacking, ndi Aggregation, ilipo kuti itumizidwe, ndikuwonjezera kubwereza kwake komanso kudalirika.Pogwiritsa ntchito kasamalidwe kakutali ndi pulogalamu-defined networking (SDN), ndizotheka kuyang'anira ndikusanthula kuchuluka kwa magalimoto, kuwongolera zida zomaliza, ndikuthetsa mavuto ngakhale maukonde akulu kwambiri.Zambiri zachitetezo zimatha kuwongolera omwe akulowa pamanetiweki, kuyang'anira kuwukira ndikuthandizira kukonza zolakwika zilizonse zomwe zimachitika.Quality of Service (QoS) imathandizira kuyika magalimoto patsogolo ndikuphatikiza zida zofananira pamodzi kuti onse athe kugwiritsa ntchito bwino zomwe zili pamanetiweki.
Kodi switch yosayendetsedwa ndi chiyani?
Ntchito yokhayo yosinthira yosayendetsedwa ndikulumikiza zida zolumikizidwa ndi Efaneti pamodzi pamaneti kuti athe kusinthanitsa deta wina ndi mnzake.Anthu ena amawona masiwichi osayendetsedwa ngati "munthu wapakati."Ngakhale imawonjezera madoko ambiri pa netiweki yanu, sizimakwaniritsa zina zambiri ndipo sizikuwoneka.
Zosintha zosayendetsedwa sizingawongolere kuchuluka kwa magalimoto pamanetiweki, koma ndizosavuta kugwiritsa ntchito chifukwa sizifunikira kusinthidwa.Chokhacho chomwe chimafunika ndikuchilumikiza. Zosintha zosayendetsedwa zimagwiritsidwa ntchito pafupipafupi m'mafakitale kuti zilumikize zida zam'mphepete kapena kuwonjezera kwakanthawi magulu a zida pamanetiweki akulu.
Zosintha zosayendetsedwa nthawi zonse zimakhala zotsika mtengo poyerekeza ndi anzawo omwe amawawongolera, komabe izi ndichifukwa choti alibe luso lapamwamba lomwe limapezeka pama switch oyendetsedwa.
Malumikizidwe oyambira osayendetsedwa, otsika mtengo ali ndi izi:
Kusintha ndi kagwiritsidwe ntchito kazodziwikiratu mukalumikizidwa. Muzosavuta zosinthira netiweki, monga nyenyezi ndi daisy chain, izi zigwira ntchito.Kuthekera kopanga ndi kusunga matebulo a adilesi ya MAC kumathandizira kasamalidwe ka magalimoto pama Ethernet hubs m'njira zingapo.Palibe kusiyana pakati pa momwe masiwichi amachitira ndi ma multicast ndi mawayilesi owulutsa, zomwe zitha kubweretsa zovuta zambiri zomwe zimadziwika kuti mvula yamkuntho.
Kusiyana pakati pa Managed Vs Unmanaged switch:
Njira yogwiritsiridwa ntchito ndiyo kusiyana kwakukulu pakati pa kusintha koyendetsedwa ndi kosayendetsedwa.Kusintha koyendetsedwa kumapereka lamulo kwa oyang'anira maukonde, kuwalola kuti aziyika patsogolo kuchuluka kwa magalimoto a LAN ndikuwongolera kuyenda kwake.Kumbali ina, chosinthira chosayendetsedwa chimangofunika kulumikizidwa ndikuyatsidwa.Zimathandizira zida za LAN kuti zizikambirana mwachinsinsi wina ndi mnzake.
Maukonde sangasinthidwe ndi chosinthira chosayendetsedwa, koma ndichosavuta kugwiritsa ntchito.Zotsatira zake, zimalandiridwa padziko lonse ndi mabizinesi atsopano.Komabe, kusintha koyendetsedwa kumathandizira kuwongolera kwa LAN, kasinthidwe, ndi kuwunika.Kuphatikiza apo, kusinthanso kwakusintha kowongolera kumathandizira kubwereza kwa data ndikubwezeretsanso ngati chipangizo kapena netiweki yalephera.
Chimodzi mwazinthu zodzitchinjiriza zosintha zosayendetsedwa ndi chivundikiro cha doko chotsekeka, chomwe chimalepheretsa mwayi wofikira pachidacho.Zosintha zoyendetsedwa, kumbali ina, zimakhala ndi chitetezo champhamvu.Itha kutseka ulusi wa zochitika, chitetezo cha data, ndikuwongolera mapulani onse ndi kuthekera kwake kuwunika ndi kuwongolera maukonde.
Si chinsinsi kuti masiwichi osayendetsedwa ndi otsika mtengo kuposa omwe amayendetsedwa nawo.Kuphatikiza apo, mtengo wake umasiyanasiyana malinga ndi madoko omwe alipo.
Nthawi zambiri, kusintha kosayendetsedwa ndi njira yabwino kwambiri pa intaneti yaying'ono, monga nyumba kapena bizinesi yaying'ono.Mabizinesi omwe ali ndi netiweki yayikulu kapena omwe amadalira malo opangira data ndipo angapindule ndi kuwongolera movutikira pamanetiweki akuyenera kuganizira kusintha koyendetsedwa.
Kusintha kwa Managed Vs Unmanaged ndi kugula iti?
Pali zinthu zambiri zomwe muyenera kuziganizira mukasankha switch yoyendetsedwa.Lankhulani ndi katswiri wodziwa za IT kapena woyang'anira maukonde.Zotsatirazi ndi zina mwa mafunso omwe ndi othandiza kuwaganizira pogula zinthu zonse.
monga ma switch amaikidwa pamalo ati?Ndikofunikira kudziwa kuti ndi anthu angati ndi zida zamagetsi zomwe zidzalowe pamaneti nthawi imodzi.Kodi kuchuluka kwa magalimoto pamanetiweki kungawongoleredwe, ndipo kasinthidwe ka netiweki amafunika?Chifukwa chiyani mukufuna kugwiritsa ntchito masiwichi?
Ndizofala kuti maukonde okhala ndi zida zolumikizidwa zosakwana khumi ndi awiri agwiritse ntchito masiwichi osayendetsedwa.Komanso, palibe chifukwa chachitetezo ndi kasamalidwe.Ma switch oyendetsedwa amapereka kusinthika kwakukulu ndi magwiridwe antchito kuposa anzawo osayendetsedwa.Imawona kutumizidwa kofala m'mabungwe monga zipatala, masukulu, ndi mabungwe aboma.
