Maseŵera otani amatha kufanana ndi ma hubs ndi ma routers
Kugwiritsira ntchito makompyuta ndi chipangizo chaching'ono chomwe chimayambitsa mauthenga pakati pa zipangizo zambiri zogwiritsidwa ntchito mu malo amodzi (LAN) .
Ma-switch- Ethernet omwe amagwiritsidwa ntchito poyima ankagwiritsidwa ntchito pamaseu apanyumba zaka zambiri asanatuluke maulendo opita kunyumba. Oyendetsa nyumba zamakono akuphatikiza mawotchi a Ethernet mwachindunji mu unit monga imodzi mwa ntchito zawo zazikulu.
Zosintha zamagetsi zogwiritsa ntchito kwambiri zimagwiritsidwabe ntchito kwambiri m'magulu ogwirizana ndi malo osungirako zinthu. Nthaŵi zina kusinthana kwa maselo kumatchedwa kusinthana mabala, kukwatirana hubs kapena madaraja a MAC.
About Network Switches
Pamene kusintha mphamvu kulipo kwa mitundu yosiyanasiyana yamagulu kuphatikizapo ATM , Fiber Channel , ndi Ring Token , kusintha kwa Ethernet ndilofala kwambiri.
Kusintha kwakukulu kwa Ethernet monga awo omwe ali mkati mwabwalo lamtunduwu amathandizira Gigabit Ethernet maulendo pamtundu uliwonse, koma kusintha kwapamwamba monga momwe zilili muzipatala nthawi zambiri kumathandizira 10 Gbps pa mgwirizano.
Mitundu yosiyanasiyana ya mawonekedwe a intaneti imathandizira zipangizo zosiyanasiyana zogwirizana. Kusintha kwa makasitomala a magetsi kumapatsa maulendo anayi kapena asanu ndi atatu pazipangizo za Ethernet, pomwe kusintha kwa makampani kumathandizira pakati pa 32 ndi 128.
Kusintha kungapangitsenso kugwirizana kwa wina ndi mzake, njira yotsalira-yowonjezera kuwonjezera chiwerengero chachikulu cha zipangizo ku LAN.
Kusintha ndi Kusayendetsedwa Kusintha
Kusintha kwachinsinsi kwachinsinsi monga momwe amagwiritsidwira ntchito mumagalimoto ogulira zinthu kumafuna kasinthidwe wapaderadera kuposa kudula zipangizo ndi mphamvu.
Poyerekeza ndi kusintha kosasinthidwa kumeneku, zipangizo zam'mwamba zamagetsi zomwe zimagwiritsidwa ntchito pazinthu zamakampani zimathandizira zida zamakono zomwe zinapangidwa kuti zizilamuliridwa ndi katswiri wotsogolera. Zowoneka bwino zamasinthidwe ogwiritsidwa ntchito zikuphatikiza polojekiti ya SNMP , link aggregation, ndi thandizo la QoS .
Kusintha kwasinthidwa mwa chikhalidwe kumamangidwira kuti kulamulidwe kuchokera ku Unix-style-line line interfaces. Gulu latsopano lamasinthidwe ogwiritsidwa ntchito omwe amatchedwa smart switches, omwe amawunikira pazomwe akulowa ndi midrange mabungwe ogwirira ntchito, kuthandizira ma intaneti omwe amafanana ndi a router kunyumba.
Mitundu Yotsutsana ndi Maofesi ndi Otsogolera
Kugwiritsira ntchito makompyuta kumafanana ndi malo amtundu . Mosiyana ndi ma-hubs, komabe mawotchi amatha kusanthula mauthenga omwe amabwera pamene akulandiridwa ndikuwatsogolera ku chitukuko china choyankhulana-teknoloji yotchedwa packet switching .
Kusinthana kumatsimikizira malo omwe amachokera komanso malo omwe amapita pa paketi iliyonse ndikupita patsogolo pazipangizo zenizeni, pamene mabalawo amapereka mapaketi ku doko lirilonse kupatula omwe adalandira magalimoto. Zimagwira ntchitoyi kuti zisunge mawonekedwe amtunduwu ndipo nthawi zambiri zimapangitsa kuti ntchito ikhale yofanana poyerekeza ndi maofesi.
Kusintha kumafanana ndi ma routers a makanema. Pamene oyendetsa ndi kusintha amasinthasintha kugwirizana kwa zipangizo zam'deralo, ma routers okha ali ndi chithandizo chothandizira kuntaneti, kunja kwa intaneti kapena intaneti.
Kusintha kwachigawo 3
Zosintha zamtundu wazinthu zimagwiritsidwa ntchito pa Mzere 2 wa Data Link Layer ya chitsanzo cha OSI . Kusintha kwachigawo 3 komwe kumagwirizanitsa zida zamkati za hardware zamagetsi ndi ma routers mu chipangizo chosakanizidwa nawonso zakhala zikugwiritsidwa ntchito pa ma intaneti ena.
Poyerekeza ndi kusintha kwachikhalidwe, kusintha kwa Gawo 3 kumapereka chithandizo chabwino kwa ma LAN (VLAN) ma configurations.
